CAUTION
Vent systems made by Heat Fab, Protech and
Z-Flex rely on gaskets or proper sealing. When
these vent systems are used, take the following
precautions:
• Make sure that gasket is in position and un-
damaged in the female end of the pipe.
• Make sure that both the male and female
pipes are free of damage prior to assembly.
• Only cut vent pipe as permitted by the vent
manufacturer in accordance with their in-
structions. When pipe is cut, cut end must
be square and carefully de-burred prior to
assembly.
WARNING
All condensate that forms in the vent must be
able to drain back to the boiler.
1. Vent Length Restrictions
a. Vent length restrictions are based on equivalent
length of vent/combustion air pipe (total length
of straight pipe plus equivalent length of ttings).
Maximum vent/combustion air lengths are listed in
Table 8. Do not exceed maximum vent/combustion
air lengths. Do not include vent/combustion air
terminals in equivalent feet calculations. See
“Combustion Air/Vent, Equivalent Length Work
Sheet”.
b. The vent termination location is restricted as per
‘General Guidelines’, Paragraph A.5. (Refer to
Figure 4)
c. Where the use of “silicone” is called for in the
following instructions, use GE RTV 106 or
equivalent for the vent collar. Air inlet piping
sections are sealed with any general-purpose
silicone sealant such as GE RTV102. PVC air inlet
piping sections are connected with PVC cement.
d. Longitudinal welded seams should not be placed at
the bottom of horizontal sections of exhaust pipe.
e. Do not drill holes in vent pipe.
f. Do not attempt to mix vent components of different
vent system manufacturers.
2.
Near Boiler Connection
To install the stainless steel vent adapter
[P/N 102219-01 (3”). 102220-01 (4”)]:
a. Push the stainless steel vent adapter onto the CPVC/
PVC connector with a slight twisting motion. Make
sure that the stainless steel vent adapter is inserted
at least 1” (refer to Figure 17).
b. Secure the adapter to the CPVC/PVC connector by
tightening the metal strap.
3.
System Assembly
a. Plan venting system to avoid possible contact with
plumbing or electrical wires. Start at vent connector
at boiler and work towards vent termination.
b. Refer to Tables 13A and 13B for approved AL29C
Vent Systems.
c. Do not exceed maximum Vent/Combustion air
length. Refer to Table 8.
d. Follow all manufacturer instructions and warnings
when preparing pipe ends for joining and using the
primer and the cement.
