IF A FURNACE AND HOT WATER HEATER ARE IN A CLOSET..

Question

I KNOW THAT SOME WHERE I HEARD THAT HEATING AND HOT WATER HEATERS THAT ARE GAS FIRED NEED TO HAVE A VENT TO ALLOW FOR AIR TO GET IN TO ALLOW FOR COMPLETE COMBUSTION TO OCCUR. SOME WHERE I REMEMBER A RULE OF THUMB THAT FOR EVERY BTU THERE IS A NEED FOR A CERTAIN AMOUNT OF SQUARE INCHES OF VENT. CAN YOU HELP ME WITH THE DETAILS?

THANK YOU,

ALAN

Hi Alan,

Check the following articles on my websites and let me know if you need additional information:

There may be different sources of combustion air for your appliances in a closet but I'd need to know how is this closet situated inside your house: what's above, below, and behind its walls.
