For PPs material, use the transition / adaptor tting (Sch 40 to PPs) offered by the
respective PPs manufacturers Centrotherm / Innoue
TM
(their part # ISAA0303 or #
ISAA0404) or M&G Dura Vent / PolyPro
TM
(# 3PPs-AD), (# 4PPs-AD) or Z-Flex/Z_DENS (#
2ZDCPVCG3). For PPs material exposed to outdoor weather, follow the venting supplier’s
recommendations on UV protection.
Combustion air piping - if used - is inserted directly into the 3" or 4" female stainless steel
tting (see Section 1.4.7).
Venting shall be supported in accordance with the applicable code.
*Manufacturers of stainless steel Type BH venting systems must submit their approved
transition tting to IBC for evaluation and written approval.
1.4.3 Vent Travel
PVC/CPVC or PPs (Rigid Single Wall) or Schedule 40 approved piping is the standard
venting option; with this, the boilers can be sited up to 200 equivalent feet from the vent
termination. The actual vent travel allowance is reduced for ttings in accordance with the
following tables. For example, for an SL 40-399 G3 using 6 x 90º CPVC vent elbows, the
maximum lineal measure of pipe allowed is 152 feet (200' – (6 x 8' = 48) = 152').
