Customer Question

REGENCY U39 GAS STOVE. Pilot works fine. When main burner is turned on (cold stove) the flame lights but then chokes out... lot of condensation on the glass. If I get the stove running with the glass door open for a couple of minutes, then close the door, all is good. 11' of vertical flue, no obstructions.

is flue all external?
Single wall?
do you have sufficient combustion air?
Or is this likely a cold stack not wanting to draft?

Customer: replied 2 years ago.
Flue is all internal direct vent so there should be plenty of combustion air. Once I have the stove heated up with the doors open there seems to be sufficient air to be able to close the door. The flame height at this point seems too high.. impinging on the top of the fire box.
Expert:  BillyHvac replied 2 years ago.
Thank you...that is indeed too high.
Have you attempted to adjust a regulator or valve?
Customer: replied 2 years ago.
all the pressures have been tested and are within specified limits for the propane conversion
Expert:  BillyHvac replied 2 years ago.
Dont know how they were tested...but if your flame is impinging on the the top you have too much pressure.
What pressure was supply and what pressure was manifold?
And do not take someones verbal...what were the numbers.
