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).
