The exhaust and intake connections are made of PVC.
Use PVC primer and solvent cement when using PVC
vent pipe. When using ABS vent pipe, use transitional
solvent cement to make connections to the PVC fitting in
the unit.
IMPORTANT
Use PVC primer and solvent cement or ABS solvent cement
meeting ASTM specifications, refer to Table 4. As an
alternate, use all purpose cement, to bond ABS, PVC, or
CPVC pipe when using fittings and pipe made of the same
materials. Use transition solvent cement when bonding ABS
to either PVC or CPVC.
Low temperature solvent cement is recommended during
cooler weather. Metal or plastic strapping may be used as
vent pipe hangers. Uniformly apply a liberal coat of PVC
primer for PVC or use a clean dry cloth for ABS to clean
inside socket surface of fitting and male end of pipe to depth
of fitting socket.
Canadian Applications Only
Pipe, fittings, primer and solvent cement used to vent
(exhaust) this appliance must be certified to ULC S636 and
supplied by a single manufacturer as part of an approved
vent (exhaust) system. When bonding the vent system to
the furnace, use ULC S636 approved One-Step Transition
Cement to bond the pipe to the flue collar. In addition, the
first three feet of vent pipe from the furnace flue collar must
be accessible for inspection.
