ADJUSTING THE PRIMARY AIR FOR
COMBUSTION
The primary air setting on the burner has been set from the factory, but may need
adjustment due to a number of factors; local gas supply variations, air supply or altitude.
The minimum allowable primary air opening for natural gas must be ¼”, and the
minimum opening for propane is ½”. Hazardous conditions may result if adjusted
below minimum settings.
Primary air adjustments are only to be performed by a qualified technician or installer, as
this procedure involves some disassembling of the burner, which must be reassembled
prior to any further use. The factory settings should be adequate for most applications.
Periodic visual inspection of the burner will determine if it is operating properly. Once the
pilot has stabilized and the burner switch is moved to the ON position, the burner should
ignite within 5 seconds. Once lit, the burner flames should be mainly bright yellow in color,
with a slightly bluish flame base. All of the burner ports should be burning, and none of the
flames should be lifting off the burner once stabilized. The flame pattern should be dancing
quite consistently, not slow or lazy. Primary air adjustment will control this effect if required,
as more air allows more motion of the flames. Consult your service agent if any burner
problems are detected.
NOTE:
Incorrect Settings Of Primary Air Control May Result In Improper
Appliance Operation. All Damages Incurred Due To This Malfunction
