Furnace temperatures


Does any one know what the exhaust gas temp is as the hot air comes out of the exhaust pipe on a hydro-flame dc8232 furnace using propane.

Also what temp is the heated air on this type furnace at the register.

My furnace exhaust gas temp is 600 to 700 F. And the inside vent temp is 130 to 144F.

Sounds high to me.

First off...........
What are you using to measure those exhaust/air temps with?

A good propane flame is BLUE (meaning complete combustion of fuel....clean/efficient)
A BLUE propane flame is 3596*F (1980*C)

A Model DC 8232 burns 32,000 btu per hour of continuous use
RV Propane system is ONLY 0.4 psi (just about what you can blow whistling)

Furnace Exhaust Grille has HOT embossed on it for a reason .....600*F/700*F is NOT abnormal----but due to low volume of spent fuel it cools off within a foot of exhaust port

Inside heated air temp of 130*F - 144*F is also normal
Furnace Heat Exchanger transfer hot exhaust temp from combustion to the air being blown thru the heat exchanger at roughly 340 CFM
That model uses a 190*F High Temp Limit Switch.........would shut down heating IF air temp reached 190*F

That is an OLD model but sounds like it is working correctly

I was using a Fluke temp meter with a k type thermal couple.

The reason I was asking was because I just replaced the dis board and cleaned up all the electrical connections. I also took a look at the burner.

Many thanks
