These were installed at a tennis club to take the place of an aging Armstrong beheamoth that took up 4 times the space.

sorry bout that

Aw Dude, where is the combustion air?? Did you check to see you had enough indoor building volume to support good clean combustion?

jvegas · 06-24-2009, 09:43 AM

Idont think that would fly in mass. maybe if there is a outdoor lover into the room with enough combustion air

hvaclover · 06-24-2009, 11:07 AM

depends if its a confined area or not. So many cubic feet of free space will give you enough combustion air.

NHMaster3015 · 06-24-2009, 11:13 AM

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

hopefully you have a drip leg on the gas line somewhere close.

hvactech · 06-28-2009, 11:00 AM

it looks like he covered the combustion air on the wall to the right doesnt it?

NHMaster3015 · 06-29-2009, 01:42 PM

Drip leg on the incoming though it's propane so not required. That cover is covering where a hot air duct ran into the office. They wanted it moved to the ceiling.

I like it. no cooling?

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.

Looks good to me, would have liked to see a pic of the old Armstrongs, use to work on a couple oil burners converted to gas long ago. could almost crawl in them big ole things! lol

My flexibles are AGA approved. I got no crap for using them

hvactech · 07-06-2009, 01:12 AM

flexibles are for those who cant measure and cut pipe to fit properly and good short cut for those hackers out there!

hvaclover · 07-06-2009, 01:46 AM

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

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.

hvaclover · 07-06-2009, 11:49 AM

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.
