combustion air

beaver canyon 041.jpgCan combustion air supply be taken from garage? This is a propane fired boiler, garage size itself is adequate. Boiler room is open to garage.
The garage is currently used as a work area, which is probably why the current owner has done this in photo.
What do you all think?

Hi to all,

Jamie, there should be no breach in the garage fire wall least of all for either returns or combustion air supply.
