BONDING OF PVC
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.
Commercially available solvent cement for PVC must be used to join
PVC pipe fittings. Follow instructions on container carefully.
Pipe and Fitting – ASTM D1785, D2466, D2661, & D2665
PVC Primer and Solvent Cement – ASTM D2564
Procedure for Cementing Joints – Ref ASTM D2855
1. Cut pipe square, remove ragged edges and burrs. Chamfer 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 APPLYING 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.
Connection of the pipe and collar of the combustion air inlet should
just be a friction fit. It is recommended that the inlet air joint be sealed
with RTV type sealant to allow the joint to be separated for possible
future service. The inlet and vent pipes must be properly supported
throughout the entire length.

Note: Follow venting instructions carefully when using PVC cement.
Important: All joints must be water tight. Flue condensate is
somewhat acidic, and leaks can cause equipment
damage.
