Weil Mclain Venting Materials

Hello.

I picked up a used Weil Mclain GV4 boiler to run in my garage to heat my infloor system.

The guy I bought it from(which is a heating contractor) told me I have to use Stainless Steel pipe for venting. After reading through the installation manuals and such it listed a couple venting options, and PVC ends up being one.

Can I use PVC with this furnace?

I have installed a couple forced air units that could be venting with PVC and I guess I don't understand why this particular closed combustion system with direct venting would care if you used PVC or Stainless Steel.

Any insight would be great!

Where did you see that you can vent in PVC?

The flue temps are too high and the PVC will just melt.

You need the starter tee also.

Here are the GV4 install manual.

I may have been a little confused.

I was reading through the GV 3" Vent brochure I got with the furnace, which is also a pdf you attached, thank you.

Page 4, Number 5 talks about Combustion Air materials

So what I am gathering is that incoming air can be PVC or basically anything, but the exhaust has to be one of the recommended:

Heat-Fab, Inc. Saf-T Vent®
• Metal-Fab, Inc. CORR/GUARD
• Z-Flex®, Inc. Z-Vent II
• ProTech Systems FasNSeal™
