    Major problems with that unit. I will not attempt to tell you anything about that system since it was plagued with problems. They might do a warranty exchange if the tank has leaks.

    Lennox is still supporting that system with parts and pieces. They discontinued the HM30 as a complete unit and replaced it with the HM61 and then discontinued that also.

    I suggest you contact a Lennox dealer and if no satisfaction there call Lennox factory.

    In your case you can try to replace the pressure switch if it is defective but in all truth your brst bet is to call a Lennox dealer.

    Here are a few pages for you to surf explaining some of the problems.
