Installing pipe clamp around pipe every 3 feet to support pipe. Install pipe clamps on each side of elbow.
Steel joint connector rings (available from Centrotherm supplier) must be used at each pipe joint. The connector rings
ensure that the joints do not separate under heavy loads. These connector rings must be used to comply with ULC‐S636
requirements. See following photo with the joint connector attached to the pipe sections.

Step 6: If any of the straight pipe sections need to be cut, use a hack saw and make a straight cut on the male
(ungasketed) end of the pipe. When making the cut, allow for the 2” minimum (51 mm) insertion distance inside the
female end of the pipe. Using a razor knife, deburr the edges of the cut pipe to make an approximately 15 degree bevel
to avoid any sharp edges that may damage the gasket.
WARNING
Cut pipe edges must be properly deburred. Damage to the gasket from not deburring the edges of the cut male
end may result in the release of dangerous flue products.
WARNING
DO NOT operate vent system without properly
installing Connector Rings.
