It's at an indoor tennis court. The building is probably 400 x 600 with 20' ceiling. Plenty of combustion air.

The size of the building has nothing to do with it. How large of a room is the unit in and does that room have enough free air for combustion coming into it.

As for a drip leg, it is required by the National Fuel Gas Code of which propane has to comply, it isn't just for Natural Gas.

You can't have a flex enter a cabinet in my area either, it has to be hard pipe at that point.

I can measure and cut with the best of them. I just don't have room in the truck after loading up for a full installation.

Nor do these old bone take kindly to the weight of the pipe stand:wheelchair:

Doesn't matter if they are AGA approved or not. They aren't allowed to enter through a cabinet in any places I work . I have had inspectors bust my chops about using them as a vibration stop on 90 pluses like the Lennox Pulse. I had an inspector ask me if I thought anyone was gonna pull out the furnace and sweep behind it.

Now there is the rub. Going thru the cabinet of the furnace is not a concern here. Sometime we put a section of garden hose as a sleeve over the portion penetrates the cabinet if there is a possible metal to metal contact.


Works good than heat.

Gas flex not allowed here either.
