    Intertherm m3rl 90+ eff. 80,000 BTU Downflow problems
    Hi, I just installed an intertherm m3rl 90+ downflow furnace today and what happens is the inducer fan runs and is venting proplerly, but when the flame lights and blower fan is signaled, the blower is blowing out the flame. How can this be possible unless there is some sort of leak in heat exchanger. Please help me!!
