The ODS pilot is a required feature for vent-free room heaters. The ODS pilot shuts off the heater if the normal air oxygen content is reduced to 18%.
Unconfined Space An unconfined space whose volume is not less than 50 cubic feet per 1,000 BTU/HR of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed, though openings not furnished with doors are considered a part of the unconfined space. Confined Space A confined space whose volume is less than 50 cubic feet for each 1,000 BTU/HR of the aggregate input rating of all appliances in that space.
in high traffic areas in windy or drafty areas IMPORTANT : Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without enough ventilation may cause mildew formation from too much moisture content. See National Fuel Code for Fresh Air for Combustion and Ventilation. This appliance may be installed in an aftermarket* manufacture (Mobile) home, where not prohibited by state or local codes.
1. Install mounting brackets on wall as shown in Figure 2. Use enclosed “paper template” for proper location of holes. It may be necessary to use plastic or lead anchors for plaster walls. 2.

Figure 7 3. Installation and repair should be done by a qualified service person. The room heater should be inspected before use and at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting and other materials. It is imperative that the control compartments, burners and circulating air passageways of the heater be kept clean. CONNECTING TO GAS SUPPLY : WARNING : Never connect an unregulated gas line to the heater.
Figure 8 LEAK CHECKING: GENERAL : Although all gas connections on the heater are leak tested at the factory prior to shipment, a complete gas tightness check must be performed at the installation site due to possible mishandling in shipment, or excessive pressure unknowingly being applied to the appliance. Periodically check the whole system for leaks, or immediately check if the smell of gas is detected. BEFORE TESTING Do not smoke while leak testing. Extinguish all open flames.
LEAK TESTING HEATER GAS CONNECTIONS: 1. Open manual shutoff valve. 2. Open main gas valve located near gas meter. 3. Make sure control knob of heater is in the OFF position. 4. Check all joints from manual gas valve up to gas control and including the manifold assembly. Apply the soap solution around the connections, valve and tubing. Soap bubbles will appear where a leak is present. 5. If a leak is present, immediately turn off gas supply, tighten any leaky fittings, turn gas on and recheck. 6.
Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don’t try to repair it, call qualified service technician or gas supplier. Force or attempted repair may result in a fire or explosion. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and replace any part of the control system and any gas control component which has been under water.
Note : If pilot goes out, repeat steps 3 through 7. TO TURN OFF GAS TO HEATER Shutting Off Heater 1. Turn control knob clockwise to the OFF position. Shutting Off Burner Only(pilot stays lit) 1. Turn control knob clockwise to the PILOT position. CAUTION Do not try to adjust heating levels by using the manual shutoff valve.
Note : The thermostat sensing bulb measures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, installation location, room size etc.). Frequent use of your heater will let you determine your own comfort levels. MANUAL LIGHTING INSTRUCTIONS 1. Remove lower front panel. 2. Follow steps 1 through 4 as stated under Lighting Instructions. 3. Press and turn control knob counterclockwise to the PILOT position. 4.

SOLVING COMMON PROBLEMS The 3 most common problems associated with any gas heater are gas leaks, wrong gas pressure and dirt. Do Not Use Your Heater Without Checking For Leaks! Leaks can occur during shipment and installation. A simple solution of soap and water dabbed on the fittings will bubble if a gas leak is present. Do not take short cuts! Wrong Gas Pressure! Too much gas pressure may severely damage your heater. Too little gas pressure and your heater will not burn correctly.
