    The manuals Im looking at say 10.5"-11.0 wc.

    With that said, I like to use a combustion analyzer to set the proper manifold pressure in an attempt to get the unit between 6-9% O2.

    Also, had a blower limit tripping due to the dumb insulators ripping my return flex off in the attic, flooding 100 degree air into it. What is a typical blower limit switch set at? Too lazy to look.

    If this is a TDH2 series, the "Reverse Flow Limit" on the blower housing OPENS at 105f, CLOSES at 95f.

    I dont know why it is called a reverse flow limit though. Not like the blower was drawing air back from the heat exchanger. It was just drawing hot air from the attic. Thanks for the specs though, its an xr95.

    That is what I was afraid of. Some what of an odd ball unit.

    The LP kit for this unit states - 9.5"wc, and the Reverse Flow Switch has 95f/85f temps.

    Check your email.

    Any chance you put a combustion analyzer on it to see the results of that pressure setting?

    What makes that a rare furnace? I guess trane's fix is a 6" spacer between furnace and coil and higher threshold limit switch to keep them from tripping. BS in my opinion.

    Most are set to 10.5"-11.0" wc for LP.

    Ive been away from resi, but back in the day, the AUH, AUY, AUX series used to be notoriously underfired with the 56 orifices in the LP kit.
