3” to 4” (100 mm) Vent/Combustion Air Transition
This section outlines the installation of Venting and
Combustion Air for the PRESTIGE 60, 110, 175, 250
and EXCELLENCE. Where the vent system must
transition from the 3” outlet of the boiler to the 4”
(100 mm) vent system.
• 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.
• 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 horizon-
tal run may result in pooling of the condensate and
potential vent blockage. Failure to comply can result
in death, serious injury or substantial property dam-
age.
• The 4” (100 mm) vent should not transition back to
3” (80 mm) vent at any point in the vent system
except when using ACV - Triangle Tube’s optional
PVC concentric vent termination kit, see kit instruc-
tions for details.
• The combustion air piping shall transition from 3” to
4” (100 mm) in the same manner as the vent system.
• The total equivalent length of the 3” (80 mm) vent
and 4” (100 mm) vent combined shall not exceed the
length listed for a 4” (100 mm) vent system Table 8,
page 8.
• The total equivalent length of 3” (80 mm) and 4”
(100 mm) combustion air piping combined shall not
exceed the length listed for combustion air in Table
8, page 8.
Insert Piping to PRESTIGE Adapters
1. The installer must clean, deburr and chamfer the
pipe ends.
The pipe ends must be smooth, free of sharp edges
chamfer and wiped clean to prevent possible dam-
age to the sealing gasket in the vent and combustion
air adapters. Failure to comply with this requirement
could result in leakage of flue products causing pos-
sible severe personal injury or death.
2. Prior to inserting the pipe, inspect the vent and com-
bustion air adapters to verify there are no obstruc-
tions or packing material inside the adapters and the
gaskets are in place.
3. Ensure the adapter banding strap is loose prior to
inserting the pipe.
4. Apply a small amount of silicon grease or 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 seated.
Do not apply excessive force, twist or bend the
adapter or vent / combustion air pipe when inserting.
The adapter gasket could be damaged resulting in
possible flue gas leakage.
6. Secure the vent and combustion air pipe by tighten-
ing the adapter banding strap. Do not over tighten
the strap. The seal is made with gasket inside the
adapter.
