OT: Side draft chimney for furnace

[flyboy71]

Well the weather here has gone from near triple digits to almost fall and I need to figure out if Im gonna heat the garage. I acquired an old working mobile home furnace last spring and Id like to temporarily install it without cutting a hole in the roof. Has anyone vented an oil furnace through an insert in an existing window using a side draft flue or something?

i will start out by saying that newer mobile home nat gas furnaces have both the intake out out take at the same place and they take a special pipe to be hoooke dup correctly. i dont know how hot a oil burner mobile homes furnace flu gets. so i dont know how to direct you on how to install the exhaust.

Yes you can do it, just use the proper vent piping.

Natural gas yes, oil I would call the building inspectors and talk it over with them. I'm pretty sure you need to do a chimney due to the chimney heat and carbon monoxide, triple wall to 24" above the peak of you roof. Cost me around $480 in materials. Single wall to the ceiling height, then an adaptor, then 8' of triple wall with a roof penetration, guy wires and a cap. Only took a couple hours to do once I read the instructions about ten times. Most restrictions are combustable within 8" of the triple wall, 24" within the single wall.

At the end of the day it was money well spent, put the thermostat next to the unit so I can keep the garage above freezing and it warms the 24x28x8 in a matter of minutes. My furnace is a Tempstar 105 kbtu. Mix 1 gallon of waster oil pre 20 gallons of heating oil. Used around $200 last year.
