1. In the U.S.A., the installation must conform with state or other codes or in the absence of such codes, refer to the latest edition of:

• Standard for Recreational Vehicles NFPA 1192
• National Fuel Gas Code ANSI Z223.1/NFPA 54

In Canada, the installation must be in accordance with:

• Standard CAN/CSA Z-240.4.2-08, Installation Requirements for Propane Appliances and Equipment in Recreational Vehicles.
• Any applicable local codes and regulations

2. Minimum clearances from combustible walls above and below counter: (See Figure 1A)

 

Models	Below Counter	Center of Burner Head(s) to adjacent vertical combustible material above the cooking surface burners.
	Sides, Rear and Bottom	Right Sidewall	Left Sidewall	Backwall
SCN SCS	0"	6"	6"	9"
SRN SRS	0"	6"	6"	9"

3. Range Cut-out dimensions illustrated in Figure 2 are as follows:

Models	Dimensions
	A	B	C	D	E
SRNS SRSS	20 3/8”	18 1/4”	2 1/2”	22 3/4”	7/16”
SRNL SRSL	20 3/8”	24”	2 1/2”	22 3/4”	7/16”
SCN SCS	20 3/8”	5 7/8”	2 1/2”	22 3/4”	7/16”

Slide-in cut-out dimensions illustrated in Figure 3 are as follows:

Models	Dimensions
	A	B	C	D	E	F
SCN SCS	20 3/8”	5 7/8”	20 5/8”	22 3/4”	2 1/4”	22 7/8”

The minimum vertical distance to combustible material above the range cooking top is 24 inches, provided the overhead construction does not extend 13 inches from the rear wall.

Note: UL and cUL certified with a minimum top clearance of 19 1/2” to overhead combustible construction when installed with a range hood spaced a minimum of 1/4” from the construction.

4. Ensure the cabinets are properly constructed. The cabinets must be squared with respect to the counter top and the cabinet face. For proper operation of these units, the cabinet must be level and the bottom of the range should be supported.
5. After the cabinet has been prepared per the dimensions given and the gas connection is in place, position the unit in the cabinet opening.

Warning

It is imperative that the cabinet in which the unit is placed be separated from other appliances so that the combustion air supply to the top burners can not be affected in any way by any forced-air heating appliance or its return air system or by any source of positive or negative air pressure, such as, but not limited to, power vents, fans, etc. A negative air pressure created by another forced air moving appliance may draw the flame down around the top burners and into the main top resulting in damage to the burners and cooktop, as well as possible personal injury and/or damage to vehicle. A positive draft could cause the burner flame to liftoff the burner and go out resulting in an uncontrolled escape of gas. Whenever the gas fumes reach an open flame or another ignition source, an explosion and/or fire will occur resulting in property damage, personal injury and/or loss of life.

6. Fasten unit in place with provided fasteners through four holes provided in side of glass cover. Secure front frame bottom tabs with two appropriate fasteners. 
7. Be sure burner knobs are in “off” position. Remove the main top. Secure 3/8” flare gas connection and turn on gas supply. Check all connections for leaks using a pressure drop test; or a soapy-water solution; or a non-corrosive leak detection solution. Do not use a soapy-water solution containing ammonia.

Caution

Gas supply tubing within the confines of the appliance connection shall be rigid or semi-rigid metallic tubing.

Warning

Never check for leaks with an open flame or any ignition source for this purpose.

 

Note: The appliance must be disconnected from the gas supply piping system during any pressure testing of that system at test pressure in excess of 1/2 PSIG. The appliance must be isolated from the gas supply piping during any pressure testing of the gas supply piping system at test pressure equal to, or less than, 1/2 PSIG.

8. If equipped with lighting, connect the red (+) and black (-) wires in the left rear of the range to a 12VDC circuit, being sure to observe correct polarity. See figure 10.
9. Install rubber trim pieces onto the side edges of main top. Pieces are located in a plastic bag stapled to this manual. Place two pieces on each side of main top, one front and one rear. The “U” shaped trim piece will slip over the vertical edge of the main top side. See Figure 5.
10. Replace main top.
11. Your unit is now ready for operation. Before operating, read the safety information and operating instructions contained in the manual.

Safety Information

Warning

If the user of this appliance fails to maintain it in the condition in which it was shipped from the factory or if the appliance is not used solely for its intended purpose or if appliance is not maintained in accordance with the instructions in this manual, then the risk of a fire and/or the production of carbon monoxide exists which can cause personal injury, property damage or loss of life.

 

Warning

Do not use surface burners with cover in closed position.

Listed below are some very important facts that you should follow. They are listed for your protection and safety.

1. Never attempt to repair the appliance yourself. Any repairs to or installation of this appliance must be performed by a qualified installer, service agency or the gas supplier and in accordance with the instructions in this manual. Service of your appliance by a non-approved service person or agency could result in failure of the integrity of the appliance and could lead to property damage, serious injury or loss of life.
2. Have your dealer show you where the main gas shut-off valve is located and how to shut it off in an emergency.
3. Use your range/cooktop only for its intended use.
4. If the range/cooktop is near a window, proper precautions should be taken to prevent curtains from blowing over burners creating a fire hazard.
5. Keep the area around the cooktop clean and clear of any combustible materials, gasoline or other flammable vapors and liquids. Not doing so can cause an explosion and/or fire.
6. Do not leave children alone or unsupervised in area where range/cooktop is being used. The top burners, burner grates and other areas near the burners become hot enough to cause severe burns.
7. Children should be taught that the range/cooktop is not a toy. They should not be allowed to play with the controls or any other parts of the appliance. Do not allow anyone to stand or sit on top of the range. Not only can this damage the range, but personal injuries could result.
8. Do not store items of interest to children in cabinets above or near the appliance. Children climbing on the appliance to reach items could be seriously injured.
9. Do not wear loose fitting clothing or long-hanging sleeved clothing while using the appliance. If they contact the open flame of the burner, they could ignite and cause severe burns.
10. Use only dry potholders to remove hot utensils. Using damp potholders on hot surfaces could result in burns to hands. Do not use a towel or bulky cloth for a pot holder. The cloth could contact open flame and catch fire.
11. Never heat an unopened container. Pressure build-up within the container can cause it to explode.
12. Keep appliance clean. The build-up of grease and food boil-over and/or spillage can create a fire hazard.
13. Avoid using your range/cooktop or any other appliance if you smell gas. Do not assume that the smell of gas in your RV is normal. Any time you detect the odor of gas, it is to be considered life threatening and corrected immediately. Extinguish any open flames including cigarettes and evacuate all persons from the vehicle. Shut off gas supply at Propane gas bottle. (See safety notice on front cover of this manual.)
14. Turn pan handles inward or toward back of cooktop and out of the way of people walking past cooktop and/or out of the reach of children. Do not turn handles to where they are over the burners.
15. Do not use water on grease fires. Never pick-up a flaming pan. Smother a flaming pan with a lid or flat pan. Flaming grease outside the pan can be extinguished with baking soda or a multipurpose dry chemical fire extinguisher.
16. Do not use the oven as a storage area.
17. Do not cover the oven vent openings whenever oven is being used. See Figure 4. Covering the vents restricts the flow of combustion air to the oven burner and could cause poor combustion and the formation of carbon monoxide.

Warning

Never cover any slots, holes or passages in the oven bottom or cover an entire rack with materials such as aluminum foil. Doing so blocks airflow through the oven and may cause carbon monoxide poisoning. Aluminum foil linings may also trap heat, causing a fire hazard.

18. Never leave top burner(s) unattended.

• For such reasons as down drafts that could be created by opening and closing of cabinet doors or doors within the RV or by positive or negative air pressures affecting burners due to improper installation. The burner could extinguish resulting in gas escaping into the RV. Remember, gas flow to each burner is controlled manually, you must turn gas flow “ON” and “OFF”.
• A boil over could occur and the spill could ignite.

19. Flame size

• Never extend the flame beyond the outer edge of the utensil. A higher flame simply wastes heat and energy.
• Correct flame size is determined by utensil size and material, what you are cooking and whether or not you are cooking with liquid.

20. To prevent damage to the cooktop, top burners, or top grate, never operate a top burner without a pan in place. The top burners, especially the high input burner, should not be operated on high for an extended period of time. The high setting should be used only to start the food cooking or to bring liquids to a boil, then reduce the flame to a lower setting to continue cooking. Use the low flame setting to keep food warm. Remember, a gas range heats quicker than an electric range; therefore, experiment with various settings until you feel comfortable cooking with gas.

Never use cookware which extends beyond one inch of the grate (maximum pan size 10” diameter). Never place cooking utensil on grate to where it rests over two operating top burners. This will cause excessive heat buildup, which results in damage to the grate, top burner(s) and cooktop.

Cookware & Bakeware Information

1. To provide proper heating and cooking performance, we suggest that you acquire cookware that fits the RV environment. Proper cookware will reduce cooking time, use less propane and provide better cooking results.
2. Foods will cook faster when the cookware is covered. This also improves cooking efficiency.
3. Select a cookware material such as aluminum or copper that conducts heat quickly and evenly.
4. When baking in the oven for the first time, allow for a period of adjustment. Because each oven has its own personal baking characteristics, do not expect your new RV oven to perform exactly like your previous oven or even your oven at home. You may find that cooking times, oven temperatures, and cooking results differ somewhat from your previous range. Follow the baking recipe and adjust as necessary.
5. Maximum pan size - 13x9x2 inch, maximum cookie sheet size - 14x10 inch.

• Shiny metal pans - reflect heat and produces lighter browning. Best used for cakes or cookies.
• Dark pans or pans with anodized bottoms - absorbs heat and produces darker browning. Best used for pies, crusts or bread.

Preheating 

1. Preheating is necessary for baking. Turn the OVEN knob to the desired temperature and allow approximately 10 to 15 minutes for the oven cavity to preheat.
2. Selecting a higher temperature will not shorten the preheat time and may affect baking results. It is not necessary to preheat for roasting or broiling.

Baking

1. Place the food to be baked in the center of the oven with 1 to 2 inches of space from the oven walls.
2. Do not block air passage or crowd the oven cavity with an oversized pan as it will affect baking.
3. If necessary, check food progress at minimal intervals until the food is done. If the oven door is opened too often, heat will escape and affect baking results.

Operating Instructions

Warning

Do not use surface burners with cover in closed position.

1. Top Burners 

• Know which knob controls which burner. Always be sure the correct burner is turned on.
• Depress knob and turn fully counter-clockwise to “Lite” position. (See figure 9.)
  • Verify sufficient gas supply before attempting to light the burner. Air in the gas line will significantly delay burner ignition. The burner may light unexpectedly as the air in the line clears and is replaced by propane gas. This unexpected ignition could burn you. Air in the gas lines may occur after the vehicle gas bottle and/or tank is refilled, during and after servicing other appliances on same gas line, etc.
  • Do not attempt to light more than one burner at a time.

If your model ends with “EC”, the burner can be lit by rotating piezo knob clockwise rapidly. This produces a spark at the burner which ignites the gas. (See figure 9.) If your model ends with “SC”, the burners can be lit by depressing the button. This produces a spark at the burner which ignites the gas. (See figure 9)

• If any burner should extinguish after initial lighting or due to accidental blow-out, turn gas off by turning control knob clockwise to “OFF”, wait five (5) minutes before attempting to relight the burner. Failure to follow these instructions could result in a fire or explosion.

If the burner should go out while cooking, or if there is an odor of gas, turn control knob(s) clockwise to “OFF”. Wait five (5) minutes for gas odor to disappear. If gas odor is still present - do not relight burners. See “What To Do If You Smell Gas” on the front cover of this manual.

• To turn burner(s) “OFF”, turn the appropriate control knob clockwise to “OFF”.

Warning

Be sure all control knobs are turned “OFF” when you are not cooking. Someone could be burned or a fire could start if a burner is accidently left on or unattended even if only momentarily.

2. Oven Burner

Note: Before the oven burner will operate, the oven pilot must be lit.

• Lighting Oven Pilot (See figure 8.):
  • Be sure ALL valves are in the “OFF” position. The oven control knob should be in the “OFF” position.
  • Be sure main gas supply is on.
  • Open oven door; smell for gas - If you smell gas STOP! Read and follow the instructions on front of your manual.
  • If you do not smell gas, turn knob to the pilot position “Push In/Lite Pilot”.
  • If range is equipped with spark ignition, depressing button will provide spark to ignite the pilot.
  • Immediately light pilot with a match. Hold knob in at least 5 to 7 seconds for this allows gas to flow to pilot and to heat thermocouple. Release knob, pilot should stay on. Note: If the appliance has not been operated for a long period of time, a longer waiting period for ignition of the pilot may be due to air in the pilot and gas lines. If pilot goes out, repeat steps a, b, c, d.
• Operation of Oven Burner:
  • Turn the oven control knob counter-clockwise to the desired setting. Oven burner will come on immediately and the oven burner will stay on until it reaches the desired setting. Then the oven burner flame will decrease in size. This is normal for this type of thermostat and this flame size will maintain a constant temperature within the oven.

Note: Oven thermostat was calibrated at the factory and is not field adjustable.

• For broiling, a 2-piece porcelain broiler pan can be purchased from Suburban:
  • Center the broiler pan underneath the oven burner flame.
  • Turn the food over frequently to ensure even browning.
• To Shut Down Oven Burner:
  • Turn oven control knob clockwise to “Pilot On” position. At this position, the oven pilot will remain lit.
• To Shut Down Oven Pilot:
  • Slightly depress knob and turn clockwise to “OFF” position. At this position, the oven pilot will go out.

3. Light Operation (If Equipped)

• To operate the blue knob backlighting only, press the switch to the up position.
• To operate the blue knob backlighting and oven cavity light, press the switch to the down position.
• To turn all lights off, return the switch to the center position.

Maintenance

1. Make sure all controls are “OFF” and the range cooktop and oven are cool before cleaning.
2. Make sure that all cooktop surfaces, burner grates and burners are cool before cleaning or disassembling cooktop.
3. Do not use oven cleaners, bleach or rust removers on the cooktop or burner grates.
4. Clean all surfaces as soon as possible after boil overs or spillovers.
5. Use warm soapy water only to clean the burner grates, cooktops, painted surfaces, porcelain surfaces, stainless steel surfaces and plastic items on your range. Do not use grit or acid-type cleaners. Do not use cleaners with ammonia. Cleaners of these types are corrosive and could damage component parts in the range.
6. Do not use steel wool or abrasive cleaners. They will damage the cooktop and oven finish. Use only non-abrasive plastic scrubbing pads.
7. Do not allow foods containing acids (such as lemon or tomato juice, or vinegar) to remain on porcelain or painted surfaces. Acids may remove the glossy finish.
8. Do not wash warm porcelain surfaces. Allow these areas to cool before cleaning. You could burn yourself or the porcelain could crack.
9. Pitting and discoloration will result if spills are allowed to remain for any length of time on stainless steel.
10. Do not allow spillovers to remain on the burner caps. The caps could be permanently stained if spillovers are not cleaned up promptly.
11. If any of the burner ports or the orifice are clogged, carefully clean with a small wire or needle. Be sure not to enlarge ports. Never use a wire brush for cleaning burner ports or orifice. Never use any brush which may “shed” bristles, which may become lodged in the orifice or burner ports and cause a fire or explosion.

To Remove the Wire Gate and Main Top for Service and Cleaning

1. ​​​​​​​Remove the wire grate by raising straight up. Use caution not to dislodge the grommets in the top (one at each corner).
2. Grasp top in the center and raise front up approximately 3”. If your unit has sealed burners, disconnect the piezo wire at each burner.
3. Slide top forward off the two spring clips at rear of top. Lift up top.

To Reinstall 

1. Reconnect piezo wires to each burner if they were removed.
2. Align slots in rear flange of top with the tabs on the spring clips. Push top in and press front of top down until the spring clip snaps into place.
3. Reinstall wire grate by aligning the four (4) legs on the wire grate with the four (4) grommets in the top. Press wire grate down into each grommet, being careful not to dislodge the grommets.

Oven Door 

Do not place excessive weight on an open oven door or stand on an open oven door as, in some cases, it could cause the range to tip over, break or damage the door to the extent that the range would be unsafe to use, or cause serious injury to the user. When opening the oven door, allow steam and hot air to escape before reaching in oven to check, add or remove food.

Oven Rack

Your RV range features one oven rack with a choice of two or three rack positions. The oven rack is designed with a safety lock-stop position to keep the rack from accidently coming completely out of the oven when pulling the rack out to add or remove food. The rack also features two tabs to keep the rack from rattling during travel. See Figure 7.

Caution

Do not attempt to change the rack position when the oven is hot.

• To Remove: Be sure the rack is cool. Pull the rack straight out until it stops. This releases the two tabs on the sides of the rack. Lift the front end of the rack up, then pull and remove from the oven.
• To Replace: Place the oven rack in the oven on top of the rack supports. Slide the rack to the stop position and lift upward then, as you push the rack back past the two tabs, it will anchor the rack into place and prevent it from rattling during transit.

Oven Bottom

When baking, use an adequate size cooking utensil to avoid boil overs or spillovers. Never place cooking utensils or aluminum foil directly on the oven bottom. This will restrict the openings in the oven bottom, reducing the air circulation inside the oven which will cause uneven baking, food may burn or be undercooked.

• To Remove: When cool, remove the oven rack. Remove the one(1) screw and nut that secures the oven burner assembly to the oven bottom (A Figure 8). Remove the four (4) screws that secure oven bottom to the oven sides and back (B Figure 8). Hold oven bottom and slide it out of the oven.
• To Replace: Position oven bottom rear flange to align with the two holes in back of the oven. Secure with (2) screws. Secure oven bottom to oven sides with the two (2) screws (see B Figure 8). Secure oven burner assembly to oven bottom with screw and nut.

Oven Bulb Replacement (If Equipped)

Ensure the oven is cool and all power is off. Unscrew the glass cover of the oven light assembly. Pull the bulb straight forward out of the socket. Replace the bulb with a G4 base, 12VDC, 10W Halogen bulb resistant to high temperature. Reinstall the glass cover.
