CHAPTER 4 - INSTALLATION REQUIREMENTS
4.1.2 3” to 4” (100 mm) Transitions
This Chapter outlines the installation of 4” (100
mm) Venting and Combustion Air piping for
all PRESTIGE Solo models and the EXCELLENCE
when the vent system must transition from the
3” outlet of the boiler to the 4” (100 mm) vent
system.
1. The transition from 3” vent system to 4” (100 mm)
vent system must occur within 5 feet [1.5 m] of the
boiler vent outlet.
2. The transition from 3” vent to 4” (100 mm) vent must
occur in a vertical run only.
Transition of 3” vent to 4” (100 mm) vent in
a horizontal run will result in pooling of the
condensate and potential vent blockage. Fail-
ure to transition from 3” vent to 4” (100 mm)
vent in a vertical run can result in substantial
property damage, serious injury, or death.
3. Use a 4”x3” bell reducer to make the transition to 4”
CPVC/PVC vent.
4. Use a 3” appliance vent adapter and 4” (100 mm)
to 3” (80 mm) reducer to make the transition to
4” (100 mm) Polypropylene vent. See Table 4 on
page 6.
5. The 4” (100 mm) vent must not transition back to
3” (80 mm) vent at any point in the vent system ex-
cept when using ACV - Triangle Tube’s optional PVC
concentric vent termination kit. See kit instructions
for details.
6. The PVC combustion air piping shall transition from
3” to 4” (100 mm) using a 4”x3” bell reducer and shall
transition in a similar manner as the vent system.
7. The total equivalent length of the 3” (80 mm) vent
and 4” (100 mm) vent piping combined shall not
exceed the length listed for a 4” (100 mm) vent sys-
tem in Table 8 on page 9
8. The total equivalent length of 3” (80 mm) and 4”
(100 mm) combustion air piping combined shall
not exceed the length listed for a 4“ (100 mm) com-
bustion air system in Table 8 on page 9.
NOTICE
WARNING
4.2. Connect Piping to PRESTIGE
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 vent and combustion air adapters are
securely attached to the top of the jacket by
turning clockwise.
• Verify there is no packing material or obstruc-
tions inside the adapters and the 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.
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 tight-
en the strap. The seal is made by the gasket inside
the adapter.
