    Default Furnace in the garage

    This is a first I wonder if they just forgot and stuck these in at the end.

    Same here, it's a regional or climate thing. Most FAU/AHU & WH are both in the garage. Easier to service and replace too.

    Gets cold in Utah? that right wall is an outside wall? no insulation. Maybe not the best arraingement. I agree with having some dont hit me posts installed. This is common?

    I have a couple of towns in the area that I service where this type install is fairly common.

    Granted we only get 1-3 inches of snow once every third year, but the furnace is in the garage. It will heat the garage enough so that nothing freezes. Common setup in my area. Add a few bollards and good to go.

    Fairly common setup in my area of operation for homes built in the 70's and 80's. Currently builders just jam the appliances in the crawlspaces and attics. Temperature wise not a big difference. At least the garage does not have to contend with basically outdoor environment of a crawlspace.

    Approximately 80% of houses around here (Oregon) have furances in the garage. The regional differences are interesting.

    I dont know how well that would work here. Minus 25c in an un-insulated, unheated sorta garage.

    Regional differences is right.

    Fairly common here in Washington, except in my area there is almost no gas appliances.

    Pretty common here in California as well. I did note that the vent connection of the water heater vent to the FAU vent is not proper. Supposed to be a Y branch fitting, not a Tee.

    I guess I would also recommend that the plenum be insulated (might be on the inside though???) since the unit is in the garage...same as if in attic or crawlspace (unconditioned). Your just wasteing heat otherwise.

    That's probably what keeps the pipes from freezing. The uninsulated plenum, that is.

    Seeing as how codes were written as minimums I would mention that installing a metal post (in addition to the raised platforms) would provide much more protection to these gas appliances. I know that most vehicles have bumpers higher than the 18 inches that most codes require for protection.

    I didn't even blink an eye at having the furnace in the garage...seems pretty common to me.

    The garage is not insulated for one and we get temps around -25 to -30. Also the furnace plenums are never sealed 100 percent so if you leave your car idling in the garage that can be a problem for CO. I think its a terrible idea But thats just me.

    Has anyone considered through wall and membrane penetrations of a fire separation wall?

    Ducts (fire damper present?) electrical panel and plumbing box?
