Bryant unit heater

Posted by on December 9, 2008, 12:34 pm

I have an older Bryant 75 K BTU unit heater installed in a new
shop...gas does not flow through the 25 volt valve. The oil-bath
solenoid opens the secondary pilot when energized, but does not open
the diaphragm main burner valve (the steel plate on the diaphragm does
not lift enough to allow gas flow). Can you suggest what the problem /
solution might be? The heater is a model 75-327, series B FG, serial
No. 131513. The Bryant gas valve is a model No.1/2 A 639.
Thank you for your consideration!
Sincerely,
Greg

professionally trained HVAC technician to dignose and repair or replace the
furnace.

My car won't run, but the dome light works.
Do you know what the problem/solution might be?

Greg,
The problem is that your old heater wont work.
The solution is to have it fixed.
