I have been getting some hot engine smellls coming into my house from
the garage. It has an exhaust vent ( probably because the hot water
heater is gas) but no fresh air intake. I would like to add a fresh
vent to the metal side door that I can close.
A google search did not come up with anything but I do not know what
they are called specifically.
Something like a ss grill 18" by 9 " with a knob in the middle that
allows you to slide a cover across blocking the holes would be
If you are getting 'hot engine' smells from garage, and there isn't a
running engine in there, you need to find out where the smell is coming from
and FIX it, before the carbon monoxide KILLS you. A water heater should
NEVER smell. I suspect you have burner troubles, or a clogged vent stack
affecting combustion. Unless your garage door is super-tight, garage should
be leaky enough to provide plenty of combustion air without adding a vent
grille. (Since W/H is in garage, I take it you live down south?) Quick
check- leave the big door open and the hot water running for awhile, to
force a long burn. Do you still get the smell?
Seriouly, guy, get it checked out. Even if garage ceiling is closed in, a
water heater out there, and the vent stack (if needed) should be trivial to
change, and relatively inexpensive labor-wise, compared to in an interior
closet or basement. Are you sure smell is from garage, and not, say, kitchen
stove, or exhaust fan? Smells can be very deceptive, collecting in areas of
poor air circulation.
Fix it correctly. Place an vent in the door and one into the attic for fresh
air. That is what is required by code. Vents should not be closed for any
If your not to far from an outside wall vent it directly to the out side and
the ceiling and forget the vent in the door. Call a plumber for specific
code issues where you live as for an estimate
ok but my original question remains - where do I find such a door
And no the smell is not dangerous in any way - it is just hot engine
and is only a problem if I close the garage door before the engine
