rheem warm air furnace

Paul S_3

I have another problem with burners not lighting fully across...brand new them two stage furnace...only one burner lights...the one closest to the spark igniter...they light full across when I blow the gas around when its trying to light....I checked incoming gas pressure I'm getting 6.8" wc....on the outlet I'm getting .40"wc reading on both high and low fire...cannot adjust both high and low regulator on gas valve....I screw the set screw all the way down and up on both high and low regulator with no change in pressure and visible firing rate....faulty gas valve???

Were you getting 6.8 in when the valve was open, or only static?

6.8"wc

With valve open

Sounds like the valve. I would try to send 24v right to it first. Could also be a low amp draw on the valve circuit, which might lead to a faulty control board.

Did you

call Rheem tech support? Sounds like a gas valve, is this a natural draft installation?

I seem to recall

hearing of manufacturing oil in the burners block the crossover. Try washing out the burners.

Is this the set screw

Adjustment that has a 2mm set screw inside a 3mm set screw? If it is you need to replace the valve and If you ever find the guy that dreamed that up, kick him in the butt.
