Vent and air piping and boiler connections
(continued)
7. The adapter accepts 3” PVC, CPVC, Polypropylene and
AL29-4C material.
For AL29-4C vent pipe ap-
plications, comply with any additional requirements in the
vent system manufacturer’s instructions. Provide a AL29-4C
starter piece from the AL29-4C manufacturer to the transi-
tion at the boiler vent connection.
8. Cut pipe to required lengths.
9. Dry assemble entire vent or air piping to ensure proper fit
before assembling any joint.
10. Maintain minimum clearance of
³⁄₁₆
inch between vent pipe
and any combustible wall or material.
11. Assembling PVC or CPVC: (
— follow pipe
manufacturer’s instructions for preparation and assembly)
a. Deburr inside and outside of pipe ends.
b. Chamfer outside of each pipe end to ensure even cement
distribution when joining.
c. Clean all pipe ends and fittings. Dry thoroughly.
d. For each joint:
s
Handle fittings and pipes carefully to prevent con-
tamination of surfaces.
s
Apply primer liberally to both joint surfaces — pipe
end and fitting socket.
s
While primer is still damp, lightly apply approved
cement to both surfaces in a uniform coating.
s
Apply a second coat to both surfaces. Avoid using
too much cement on sockets to prevent cement
buildup inside.
s
With cement still wet, insert pipe into fitting, twist-
ing ¼ turn. Make sure pipe is fully inserted.
s
Wipe excess cement from joint. Check joint to be
sure a smooth bead of cement shows around the
entire joint.
12. Seal wall or floor penetration openings following local code
requirements.
1. Clean and deburr inside and outside of both ends of air and vent
pipes. Chamfer boiler end of vent pipe for ease of insertion.
The vent pipe end must be smooth and chamfered to
prevent possible damage to sealing gasket in vent pipe
adapter.
2. Inspect vent or air adapter (above) — verify no obstructions or
foreign objects inside.
3. Loosen clamp screw (if used).
4. Measure 2¼-inches from end of pipe and make a mark with felt-
tip pen.
5. Apply small amount of silicon grease to end of pipe to ease insertion.
6. Insert pipe into adapter.
7. Slide pipe down until the 2¼-inch mark is reached.
Do not apply excessive force or bend the adapter or flue/
air pipe when inserting. The adapter or seal could be dam-
aged. If any portion of the vent or air system is damaged,
it must be replaced.
8. The seal is accomplished with the internal gasket.

Control selection for vent material
To insure proper boiler operation the boiler control is pro-
grammed default is for PVC venting material. You
MUST

you installed other than PVC, in order to improve operational
efficiency.
Refer to “
Quick Start Guide
” page 3, to first power up the boiler.
To access the configuration menu:

”.
4. Press the DHW buttons (+ or -) to view or modify the value
of a parameter: the modification will be automatically saved.
