Gas water heater inside the cabinet

0 votes

Hello,
 I have a question, Our gas water heater is in a cabinet inside. The cabinet is old and has venting grills on the bottom and top of the door. When we had the water heater replaced a few years ago, it was properly vented to the outside. We are going to replace the cabinet now and I was wondering, do we need to vent the door again now that the heater has been vented to the outside?
 
I hate to put holes in the new door if it is unnecessary. If we do need to vent the door, do you know what size the holes need to be for code? Currently they are 14in wide and 8in high. I would appreciate your expertise on this!

Hi, unfortunately you do need those holes, if you follow this link, I’ve explained everything in more detail – Combustion Air for Fuel Burning Appliances. Proper venting of your water heater and your safety depends on air supplied for its combustion.

If your water heater closet / cabinet has an exterior wall (to the outside), there’s an attic above or basement / crawlspace underneath, you’ll have more choices which could save your new door. Let me know or check the post link above.
