Furnace Exhaust Vent Changes
Hello -- I want to build a deck off the back of my house, but the existing PVC furnace vent is messing up my planned design. Is it OK for me to cut the vent where it exits the house, splice in another 6" or so of length, and then reattach the vent pipe? This way I can bring the vent up through a corner of my new deck. I'm not sure whether there is a standard building code that addresses such things. Please help! Thanks, Sue
Sure you can. Offset it with two-45's. You are going to see the pipe anyway, so a few modifications should not get in the way of your new plans. As far as the height is concerned, YES check local codes to determine the height. Even though the pressure switch would shut-off the gas valve in the event of a blockage, due to snow, birds nest, etc. You can also check the manufactures' suggested height requirement, but local codes take precedence.
