VENT FITTING MATERIAL – PLASTIC
Gas and liquid tight single wall vent fittings, designed for
resistance to corrosive flue condensate, MUST be used
throughout.
Listed in Table 7 are 2", 2-1/2", and 3" size fittings that meet
these requirements. The materials listed are various grades
of PVC and ABS plastic.
PIPE JOINTS: All joints must be fastened and sealed to
prevent escape of combustion products into the building.
NOTE:
It is recommended that the first joints from the furnace be
connected and sealed with high temperature RTV. This will
enable the pipes to be removed later without cutting.
Be sure to properly support these joints.
BONDING OF PVC
Commercially available solvent cement for PVC must be
used to join PVC pipe fittings. Follow instructions on con-
tainer carefully.

PVC Primer and Solvent Cement – ASTM D2564.

All joints must be water tight. Flue condensate is somewhat
acidic, and leaks can cause equipment damage.

1. Cut pipe square, remove ragged edges and burrs. Cham-
fer end of pipe, then clean fitting socket and pipe joint
area of all dirt, grease, moisture or chips.
2. After checking pipe and socket for proper fit, wipe socket
and pipe with cleaner-primer. Apply a liberal coat of
primer to inside surface of socket and outside of pipe.
DO NOT ALLOW PRIMER TO DRY BEFORE APPLY-
ING CEMENT.
3. Apply a thin coat of cement evenly in the socket. Quickly
apply a heavy coat of cement to the pipe end and insert
pipe into fitting with a slight twisting movement until it
bottoms out.
4. Hold the pipe in the fitting for 30 seconds to prevent
tapered socket from pushing the pipe out of the fitting.
5. Wipe all excess cement from the joint with a rag. Allow
15 minutes before handling. Cure time varies according
to fit, temperature and humidity.
