Thread: Oil furnace in closet

    Default Oil furnace in closet

    I never had oil heat before, so I'm looking for some info please. The furnace was installed 2 years ago in a closet space in the hallway of a mobile home. When I bought the place, there was a piece of sheetrock that had been removed from above the furnace. I don't know whether they just didn't feel like putting it back, or if the furnace really needs to have open space above it. Anyway, my brother found it and just screwed it back in place. Now I'm worried that it was taken off for a reason. Any help? Thanks.....

    Someone probably took it off to either see what was back there or to get at the flue or firomatic switch and couldn't be bothered to put it back. Either way it does not have to be there but the hallway sure looks better if it is.

    Is it not possible the air flows down and somebody left the top open as the return?

    Now I'm worried again. On the door of the unit there are louvered vents backed by a filter. When the furnace is running, cool air comes out through the vents. I thought this was the return. I guess my question is when installing a furnace unit, does there need to be a certain amount of space above it left open?
    ............I don't want to die in my sleep from carbon monoxide. I at least want to know ahead of time so I can load up on beer, pizza and cigarettes, which I haven't had in a very long time but still long for. Maybe I should do that anyway, just in case!

    A picture or two would be very helpful here. The filtered lovers you are describing do sound like the room-air intake for the heat exchanger, but there should not be any air coming out of them, and there should be no cool air coming out anywhere for as long as the heat exchanger is warm.

    There are clearance requirements related to fire prevention, but not all furnaces are ducted in the same way. I lived in an older mobile home many years ago, and the hallway was the cold air return for the furnace closet with its louvers flush on the wall. After you figure out the flow of room air through your furnace, you need to be sure the blower can pull unrestricted air in ... and that might be why the top of your furnace closet was open even though the bottom would be better if your intake louvers are low. Another possibility here is that your blower is running backwards. I made that discovery once after a landlord had installed a new blower motor a year or two before my wife and I had rented the place. The previous tenants had complained about high gas bills, and ours dropped dramatically after I got the blower running in the proper direction.

    From wherever your furnace gets room air even before that air gets to the intake louvers, some of that air goes through the firebox and out the chimney. Therefore, a non-ducted furnace (no return ducting) in a sealed closet is being choked, and that would definitely not be good.

    It would be worth a hundred dollars or so for you to have an oil furnace pro come take a look and let you know whether everything is fine if you cannot figure that out for yourself for sure.

    Default furnace

    We have no where near enough information on your installation to even make an educated guess as to whether it is a safe installation or not. But you should have a competent local service person check it out.
