4.1 Approved Venting Materials

WARNING
We recommend that the Condensing boiler be vented with approved polypropylene venting material. This can be with
either coaxial venting or with the two pipe rigid vent system. Use only materials listed below for vent pipe, intake air
pipe and fittings. Failure to comply could result in personal injury, death or property damage. Installations must comply with
local code requirements and with U.S.ANSI Z223.1
All venting must be properly supported. The boilers are not intended to support any type of vent system whatsoever.
All piping, glue, solvents, cleaners, fittings and components must conform to ASTM and ANSI standards.
Note: In Canada ULC S636 and in the USA UL 1738 schedule 40 CPVC are the only approved vent system to be used as
an alternative to polypropylene venting for the exhaust pipe.
Vent Material Options:
1. 100mm / 60mm Polypropylene concentric ("4 inch/ 2 inch")
or
2. 80 mm polypropylene twin pipe (MUST be polyproylene on BOTH intake and exhaust) ("3 inch")
or
3. 3" Twin pipe CPVC (PVC optional on intake ONLY).
