It is advisable to extend this to the wall behind the appliance. Clearances to combustibles are as follows: • From jacket to adjacent side walls, 2” on the 20/35, and 6” on the 50/70. Maintain adequate clearance on right side for accessibility. • From rear surface vertical vent pipe to rear walls – 6”. • From rear of unit to rear wall, 13” on 20/35, and 14” on the 50/70. • From top of heater to ceiling, 34” on the 20/35, and 31” Projection on the 50/70. • From top of heater to any overhanging projections such as a mantle or window sill is 22” on the 20/35, and 19 inches on the 50/70 models, with a maximum horizontal extension of 18 inches. The clearances around the air opening into the combustion chamber must be maintained, and the burner must be kept clean. Do not permit dust or dirt to accumulate here. The other clearances previously mentioned must be maintained. There must be adequate room provided and maintained around the heater for accessibility and for the flow of combustion and ventilation air.Projection TEMPERATURE CONTROL BLOCKED FLUE SWITCH PILOT GENERATOR PILOT ADJUSTMENT MAIN BURNER ORIFICE The pilot flame can be observed by opening the pilot lighting hole cover. The pilot flame should surround the top 3/8 to . inch of the thermocouple (see Figure 2). If the flame needs adjusting, first locate the pilot adjustment screw cap and remove. Adjustment screw is underneath (see Figure 1). To increase the flame, turn the pilot adjustment screw counterclockwise . To decrease the flame, turn the screw clockwise . NOTE: The pilot is unregulated. If incoming line pressure is more than 7” w.c. Natural Gas or 11” w.c. for L.P. Gas, the pilot flame size should be decreased. Pilot Adj. Screw FIGURE 1 PILOT FLAME 3/8 TOADJUST-1/2 INCH MENT Pilot flame should envelop 3/8 to 1/2 inch on the tip of the generator. FIGURE 2 RADIANTS AND GLASS PANELS FOR ALL VCRMODELS (See Figure 9 – Replacement Parts Section) INSTALL GLASS AND RADIANTS AS FOLLOWS: STEP 1. Remove three screws from under top of opening in bezel frame assembly. STEP 2. Pull top of bezel down and lay aside. STEP 3. Remove glass from bottom pad in shipping carton. STEP 4. Remove carton containing radiants from cavity of combustion chamber. STEP 5. Remove radiants from carton and install by tilting backwards and lifting at the same time into opening. Place the radiants on the burner radiants supports. The radiants must be straight. Never operate heater if any radiant is tilted to front or rear. Continued This appliance was shipped from the factory with an orifice sized to give the correct gas input using the gas for which the heater was equipped. There may be local conditions, such as variation in gas pressure or BTU content of the gas, which may be cause for a change in the orifice. The gas company supplying the fuel or the installing contractor should check the gas input rate. If the rate exceeds the “BTUH INPUT” on the rating plate by 5%, the orifice should be replaced with a smaller orifice by a qualified technician to reduce the input to the rating plate value. The input rate may need to be adjusted for elevation. See the following charts to determine the correct orifice size for your Model Number and elevation. These orifice sizes are based on a heating value of 1020 for Natural Gas and 2500 for L.P. Gas. CAUTION: As elevation increases, derating is necessary for the safe and proper operation of this heater. Do not increase the Btu input rate by increasing the orifice size or gas pressure. Allow for elevation derating when sizing gas heatin...
