Proheat installed in Bay - enough air intake?

[daveola]

I have a Proheat XL900 that I am going to install.  I don't really have space for it in the normal A/C bay, so I am planning on putting it in one of my luggage bays (where the water supply is so that it can also help keep the water from freezing).

But I see that the Proheat needs, of course, fresh air intake.  Is there enough leakage into the luggage bays to get fresh air for combustion, or do I need to vent it?

You definitely need to supply a source of fresh air.  If you have a couple square inches of holes throughout the bay then you should be good.  If not, add a fresh air intake.
