Furnace in closet

[Steve A. Rinner]

Is a gas forced air furnace ever allowed in a bedroom closet?

Thanks in advance

[Kevin L. Luce]

Depends on the furnace. If there are two PVC pipes connected to the furnace and both pipes are terminated to the exterior, no problem.

Just keeping it simple.

Sure ... if it's direct vent as Kevin noted (exception #1 above), or has a self closing door and combustion air if from the outside with no door grille (exception #5 above).

Ive seen water heaters installed in dead spaces in mobile holes, accessible via removable panels held in place by screws, with a grille to the exterior allowing for combustion air.

I sometimes see water heaters in small bedroom closets with the concentric sidewall vent terminations ... no issues with that at all.

Check the listing of the gas appliance. Most say "not approved for use in manufactured homes".
