    Default oil furnace in the garage.

    Exposed oil furnace with AC in the garage.
    Require a narrative considering venting is exposed.
    Looking for a canadian standard or something applicable.

    Picture?
    Is the oil tank in proximity to furnace or on the exterior of garage?
    Is the furnace protected from damage - bollards?
    Not sure what you mean by venting exposed?

    Also found this on oil tanks, although it has nothing to do with your question, its very good information albeit for North West Territories.

    Interior garage.
    Could not locate oil tank.
    Too much stuff.
    Could not get an image with the car removed.
    Plenum, return and supply and branches in the garage.
    Circa 1987 everything.

    If it supplies interior of home it's wrong because CO can be carried into living space.

    Replying on my phone so hard see about the photo - but isn't the heated air system in a closed loop to/from the living space and separate from the combustion air system in the garage?

    Just like when a furnace is in an attic or basement.

    I am also under the impression the system is in the garage and not separate in its own room ... just like it would be in an attic or basement.

    The only time the duct (return air) is not sealed to the unit would be when the unit is in the conditioned space, right?

    Otherwise you would be having to heat the air of whatever temperature was outside (if the unit was in an attic) or whatever the air temperature was in the basement, leading to a very inefficient system trying to heat -40 degree air to 70 degrees, or even trying to heat 40 degree air in a basement to 70 degrees, and having to keep heating fresh air instead of just having to re-heat the environmental air in the conditioned space.

    Oil tank outside underground somewhere? In an inaccessible compartment off the garage? In a basement?

    Ductwork in a garage needs to be:
    - sealed just like all other ductwork needs to be
    - protected from physical damage
    - insulated just like all other ductwork not in conditioned space needs to be
    - properly supported

    Furnace in garage needs proper combustion air.

    Vent from furnace in garage needs to not be insulated (if that insulted item in the photo is the vent).

    As Raymond said - need more information, paint the picture better for us.

    You guys way up north there need to make sure that silly looking fat guy feeds those weird horses with horn things well, they have a lot of work scheduled for tonight.

    Happy Holidays!

    Jerry,

    I was using my phone to look and post about the furnace too.

    Now back on my computer. I agree with your assessment.

    Further concern with duct work at cleats, they are not sealed.

    Also its a power vent exhaust.

    From that post you linked too:

    "But, I will add that open combustion flames present a hazard for combustion gases and by-products (Carbon Monoxide for one) to reach the inhabitants of the dwelling you are inspecting. Forced air furnaces and other Air Handlers that have ductwork in garages can be the pathway to draw in these hazards. "

    Somehow, putting the furnace in the garage is MORE dangerous than putting that very same furnace INSIDE the living space (because carbon monoxide can get into the ductwork from the garage, but it's okay to allow that same carbon monoxide to just roll out into the living space?

    Either I am missing something or he did not think the reply through.

    I don't know about up there, but the IRC requires the ignition source (flame, spark, anything which can ignite something else) be at least 18 inches above the garage floor.

    Everything appears correct.
    The burner was 18" inches above the flooring.
