Product Q&A
12 QuestionsQ: The vent kit instructions show the combustion air entering the bottom on a side wall termination (Figure 7). The water heater manual also shows combustion air entering the bottom on a side wall termination (Figures 24, 25, and 29). However, Figure 23 shows combustion air entering from the top and has a note "important: intake leg must be facing up." Should the intake leg face up or down on a side wall termination? I think I can only accommodate down...

Q: How is this lengthened?
Asked by Partsguy 13 years ago

The air intake can't be lengthened since it is behind the rim of the vent, but the exhaust in the center can simply be added to by gluing pipe to your required length. I recommend keeping the exhaust and intake at least 3 feet away from each other since the exhaust is loaded with moisture that will freeze in the intake screen if too close.
Not really sure since its a intake pipe in a exhaust pipe at the exit end. If memory serves me right there is a Y branching at the end that allows the intake and exhaust to be separately run with PVC. I will reply this weekend with correct answer once I get to house to look at it as it is my weekend lake house. We took the exit end out of the side of the house on wall opposite where water heater was installed so run was only about 5 feet. Only issue I had was the intake didn't appear to come with a screen and we had some swifts build a nest in it which shut water heater down (good sensor on the water heater to detect the blockage). I was able to by pass the block at the heater and draw air from the basement directly at intake blower until I figured out problem. There was a screen in the pipe just short of the blower, but I think the plumber installed it there instead of on the outside of the house at intake entrance, it may have been the one that came with the unit?. Once I put a vacuum cleaner into intake on heater side on blow/exhaust I was able to blow birds and nest out. Unfortunately the birds didn't survive the experience as they we on the nest when we started up house and water heater. I added a screen on the outside intake end using one of the U shaped gutter down pipe screens which fit perfectly in the opening and left the original where it was as a backup, plus I couldn't get it out anyway with out cutting pipe at joint. It is a heavy well built PVC pipe system.
You choose how long to make your pipe. The instructions make it clear. But be sure you don’t exceed the max length & 90deg bend rules. If the included pipe isn’t long enough, use a PVC coupling.
Q: I was asked can a furnace and water heater be vented into one concentric vent if a 3"/ 4" is used instead of a normal 2"/ 3" I could not find an answer for this person.

Verified Reply- PexSupply StaffThis is not recommended by the manufacturer.
I would avoid combining vents for two appliances. Don't even think about if unless they are both sealed-combustion type. The problem is that when only one appliance is running, some of its exhaust will be pushed backward through the exhaust system of the other appliance into the fresh air intake. Some will recirculate into the running appliance's intake, reducing efficiency. When the other appliance starts, it will have exhaust in its intake piping, and probably won't have a long enough purge cycle to get it all out.
No. Each appliance must be vented separately with it's own dedicated piping or concentric vent. If you hooked them to the same vent then one appliance would backdraft into the other. Not to mention it would void your warranties on both appliances. Brian P Tahlequah, Ok 74464
I really doubt that you could do that. You cannot even extend the vent for a single water heater.
