COMBUSTION AND VENTILATION AIR When installed, this gas appliance must be provided with fresh air for combustion, ventilation, and dilution of hot flue gases. The minimum required volume of the area where the appliance is installed should be 50 cubic feet per 1,000 btu/hr.
DRAFT DIVERTER The draft diverter must be installed in the same atmospheric pressure zone as the combustion air supply for the main burner. DOOR KNOB Remove from the inside of the casing door and assemble to the outside of the door. VC201 and VC202 have finger holes in the door in lieu of knob.
PILOT ADJUSTMENT The pilot flame can be observed by opening the pilot lighting hole cover. The pilot flame should surround the top 3/8 to ½ 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).
CAUTION: There may be momentary and spasmodic orange flashes in the flame. This is caused by the burning of air borne dust particles and is not to be confused with the yellow tipping which is a stable or permanent situation when there is insufficient primary air.
