in Radiant Heating
I'm in the process of installing the input and exhaust on my micro boiler for the radiant heat in my Morton building, do I need to install a backdraft preventer on the exhaust side? There isn't any mention of it in the installation directions that I can see. I'm use Schedule 40 ASTM D1785 PVC for both.
Thanks.

    Do not install a damper on the exhaust. Just pipe it like the manual and you are good to go. In addition the the other post. Pitch the pipe carefully and be sure the primer and cement is for PVC exclusively. I keep seeing universal cements in the big box stores. Use only PVC cement and primer
