CHAPTER 4 - INSTALLATION REQUIREMENTS
4.2. Connect Piping to INSTINCT
The INSTINCT appliance is supplied with an
acoustic dampening foam rubber insert lo-
cated in the appliance air inlet adaptor.
DO NOT remove this at installation.
The INSTINCT universal vent and combustion air
adapters will directly accept PVC/CPVC, DuraVent FasN-
Seal Polypropylene (PP), and AL29-4C Stainless Steel
venting without the use of adapters.
The universal vent and combustion air adapters
contain three seals for each type of venting material.
• The uppermost seal is used for PVC/CPVC venting.
• The middle seal is used for DuraVent FasNSeal
Polypropylene (PP) venting.
• The bottom seal is used for AL29-4C Stainless
Steel venting.
1. The installer must clean, deburr and chamfer the
pipe ends prior to assembly.
The pipe ends must be smooth, free of sharp
edges, chamfered and wiped clean to prevent
possible damage to the sealing gasket in the
vent and combustion air adapters. Failure to
comply with this requirement can cause flue
gas leakage, resulting in substantial property
damage, serious injury, or death.
2. Prior to inserting the pipe into the adapter:
• Verify the adapter gaskets are in place.
3. Ensure the adapter retaining strap is loose prior to
inserting the pipe.
4. Apply a small amount of water to the insertion end
of the pipe to ease insertion into the adapter.
5. Insert the pipe into the adapter until it is fully seat-
ed to the proper level for the type of venting mate-
rial being utilized.
Do not bend, twist or apply excessive force to
the vent or combustion air adapters when in-
stalling the vent / combustion air piping. The
adapter gasket could be damaged and leak
flue gas, resulting in substantial property dam-
age, serious injury, or death.
6. Secure the vent and combustion air pipes by tight-
ening the adapter retaining strap. Do not over
tighten the strap. The seal is made by the gasket
inside the adapter.

4.3. Vent and Combustion Air Piping Installation
4.3.1 PVC/CPVC Vent System
1. The installer should install the vent / combustion air
piping working from the boiler to the piping termina-
tion. The piping length must not exceed the lengths
listed in Table 8 on page 9.
2. The installer should cut the pipe to the required length
and must deburr the inside and outside of both ends.
3. The installer must chamfer the outside of the pipe ends
to allow even distribution of cement when joining.
4. The installer must dry assemble the vent system pri-
or to nal assembly to ensure proper t.
5. The pipe ends and ttings must be cleaned and
dried thoroughly prior to nal assembly.
6. When assembling a joint the installer must:
a. Handle ttings and pipes carefully to prevent
contamination of surfaces
b. Apply a liberal amount of primer to both the end
of the pipe and the insert socket of the tting.
c. Apply a light uniform coating of approved ce-
ment to both the end of the pipe and the insert
socket of the tting, while the primer is still wet.
d. A second coat of approved cement should be
applied to the mating surfaces. The installer
should avoid, however, using too much cement
on the socket of the tting to prevent a buildup
of cement on the inside.
e. With the cement still wet, the pipe end should
be inserted into the socket of the tting and
twisted 1/4 of a full turn. Ensure the pipe end is
inserted fully into the socket of the tting.
f. Any excess cement should be wiped clean from
the joint. Inspect the joint to ensure a smooth
bead of cement is around the entire joint seam.
7. The installer must use perforated metal strap hangers
or equivalent pipe hangers suitable for plastic pipe to
support the piping. The hangers must be placed at
a maximum of every 5 feet [1.5 m] of horizontal and
vertical run of piping. A support must be placed at
the boiler and at every vertical or horizontal change
in direction (i.e elbow). Do not penetrate any part of
the piping or vent system with a fastener.
Failure to properly support vent system can
cause the venting system to fail, resulting in
substantial property damage, serious injury,
or death.
