    problem with sealed combustion

    I just installed a new buderus g244/37 sealed combustion boiler. I can not get the flame to burn correctly. The fan is running and bringing air in but the temp of the boiler will not rise. I took the front of the boiler off to let in air and it runns great temp goes up no problem! If i put the door on, it starts to starve for air again.
    I have checked for obstructions in the flue and fresh air intake. The only problem i think that i have is that we converted this to propane and the boiler may need to be adjusted to burn properly when combustion door is sealed. The flame is blue and burns fine when the door is off.
    What do you think??

    Proper combustion

    Have you converted the gas valve with the propane kit?

    Have you tested and adjusted the incoming gas pressure with a manometer?

    This must be done, or not only will the warranty be void, you can damage the gas trane....or create a CO problem...get help from Buderus tech services or your rep or wholesaler.

    Did you...

    follow the installation manual to the T?

    Incoming pressure adjustments is critical, and the use of a combustion analyzer is necessary. You just can't eyeball stuff anynmore. What may appear to look good can kill you.

    Aren't you in the Denver area G-Dawg?

    Get out your test instruments

    First the manometer to verify both incoming and manifold gas pressure. Then use it to see what your intake and exhaust pressures are. After checking those use your combustion analyzer to see what's going on with the flame. As in O2, CO, CO2, flue temp etc. I'm betting that something revealed by those tests will jump out at you.
