1.
Work from the boiler to vent or air termination. Do not
exceed the lengths given in this manual for the air or vent
piping.
2.
Cut pipe to the required lengths and deburr the inside
and outside of the pipe ends.
3.
Chamfer outside of each pipe end to ensure even
cement distribution when joining.
4.
Clean all pipe ends and fittings using a clean dry rag.
(Moisture will retard curing and dirt or grease will prevent
adhesion.)

Installation & Operation Manual
Dry fit vent or air piping to ensure proper fit up
before assembling any joint. The pipe should go
a third to two-thirds into the fitting to ensure
proper sealing after cement is applied.
Priming and Cementing:
a.
Handle fittings and pipes carefully to prevent
contamination of surfaces.
b. Apply a liberal even coat of primer to the fitting
socket and to the pipe end to approximately 1/2"
beyond the socket depth.
c.
Apply a second primer coat to the fitting
socket.
d. While primer is still wet, apply an even coat of
approved cement to the pipe equal to the
depth of the fitting socket along with an even
coat of approved cement to the fitting socket.
e.
Apply a second coat of cement to the pipe.
f.
While the cement is still wet, insert the pipe into
the fitting, if possible twist the pipe a 1/4 turn as
you insert it. NOTE: If voids are present,
sufficient cement was not applied and joint could
be defective.
g.
Wipe excess cement from the joint removing
ring or beads as it will needlessly soften the
pipe.
