In the case of PVC venting, the flue venting pipe is affixed to the adapter using RTV liquid
silicone and then clamped with a worm-driven Hose Clamp.
When using non-metallic (plastic) venting materials, use schedule 40 or thicker, single-wall,
uninsulated pipes. When using non-metallic (plastic) vent systems for Canadian installations,
per CSA B149.1, use vent systems that are certified to the standard for Type BH Gas Venting
