Combustion Air Source

[cowboyplumbing]

We've got a boiler in a closet in a garage with some bypass closet doors on it. It had combustion air in there until those vents were blocked off with cardboard. Likely someone realized running the zone plumbing directly in front of the air vents was a less than ideal install and fixed that with their Amazon box. Could the combustion air vents be relocated to the other side of the garage or is there a distance limitation between the boiler and the vents? How could we separate the heat and the vents a little better here? Thanks. Brendan.

Use one of these.

There is a distance limit. It's based on the size of the pipe and the size of the boiler.

Here's a couple of formulas for make up air. Garage have heat, water heater and how cold does it get in your area? Since the make up was closed off most garages leak enough air for a boiler.

Tech Tip: Do you have enough make-up air to support proper combustion?
