IMPORTANT
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 fittings
in the unit.

Table 2.
Use PVC primer and solvent cement or ABS solvent
cement meeting ASTM specifications, refer to Table 2.
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. Metal
or plastic strapping may be used for vent pipe hangers.
Uniformly apply a liberal coat of PVC primer for PVC.
Canadian Applications Only – Pipe, fittings, primer and
solvent cement used to vent (exhaust) this appliance
must be certified to ULCS636 and supplied by a single
manufacturer as part of an approved vent (exhaust)
system. In addition, the first three feet of vent pipe from the
furnace flue collar must be accessible for inspection.
Table 3 lists the available exhaust termination kits, as well
as vent pipe equivalencies, which must be used when
sizing vent pipe.
Joint Cementing Procedure
All cementing of joints should be done according to the
specifications outlined in ASTM D2855.
DANGER OF EXPLOSION!
Fumes from PVC glue may ignite during system check.
Allow fumes to dissipate for at least 5 minutes before
placing unit into operation.
1.
Measure and cut vent pipe to desired length.
2.
Debur and chamfer end of pipe, removing any ridges
or rough edges. If end is not chamfered, edge of pipe
may remove cement from fitting socket and result in a
leaking joint.
3.
Clean and dry surfaces to be joined.
4.
Test fit joint and mark depth of fitting on outside of pipe.
5.
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.
6.
Promptly apply solvent cement to end of pipe and
inside socket surface of fitting. Cement should be
applied lightly but uniformly to inside of socket. Take
care to keep excess cement out of socket. Apply
second coat to end of pipe.
NOTE: Time is critical at this stage. Do not allow
primer to dry before applying cement.
7.
Immediately after applying last coat of cement to pipe,
and while both inside socket surface and end of pipe
are wet with cement, forcefully insert end of pipe into
socket until it bottoms out. Turn PVC pipe 1/4 turn
