Tx Series Installation and Operation Instructions

Trinity
13
Near Boiler Vent/Air-inlet Piping
The Trinity Tx employs universal Vent and Air-inlet appliance adapters that accept either 3” PVC/CPVC or 3”
Polypropylene (PPs) venting, without the need for additional adapters. The appliance adapters incorporate two
seals, one for the larger diameter PVC/CPVC pipe (3.5” OD), and one for the smaller diameter PPs pipe (3.15”
OD). The exhaust/vent adapter uses a toothed-ring to prevent the vent pipe from being pulled out once it is
inserted.
PVC/CPVC Piping
– Remove the
lower
gasket and toothed-ring from the exhaust adapter to avoid damage from
flue gas condensate; the 3” PVC/CPVC has an outside diameter of 3.5” and will seat into the upper portion of the
adapter. Ensure the
upper
gasket and toothed-ring are in place and properly positioned prior to installation.
Ensure the venting system does not apply a load or strain on the boiler flue outlet adapter; recommend using two
elbows to create a “swing joint” to reduce potential strain on vent piping and cemented joints. See Figure 4-2(a).
PPs Piping
– 3” PPs has an outside diameter of 3.15” and will seat into the lower portion of the adapter. Ensure
the
lower
gasket and toothed-ring are in place and properly positioned prior to installation Ensure the venting
system does not apply a load or strain on the boiler flue outlet adapter; recommend using an elbow with an offset
to reduce potential strain on vent piping and cemented joints. See Figure 4-2(b).
Stainless Steel Piping
– The Trinity Tx has been tested and approved for use with DuraVent – FasNSeal AL29-
4C Stainless Steel Special Gas Vent. Venting with FasNSeal will require DuraVent adapter part number 300715
(contact DuraVent at 1-800-835-4429 or www.duravent.com). Remove the
lower
gasket and toothed-ring from
the appliance exhaust adapter to avoid damage from flue gas condensate; the DuraVent adapter has an outside
diameter of 3.5” and will seat into the upper portion of the appliance adapter. Ensure the
upper
gasket and
toothed-ring are in place and properly positioned prior to installation. Ensure the venting system does not apply
a load or strain on the boiler flue outlet adapter; recommend using two elbows to create a “swing joint” to reduce
potential strain on vent piping and cemented joints. See Figure 4-2(c).
Gasket Seating
- Improper seating can cause leakage and eventual failure of the sealing
gasket. Ensure the vent pipe is adequately beveled prior to inserting into the boiler flue
adapter. Failure to follow these instructions may result in serious injury or death.
Toothed-Ring
- Failure to ensure the toothed-ring is properly in place and securing the
exhaust vent pipe to the appliance adapter may result in serious injury or death.
Exhaust venting must be supported to reduce strain on piping joints. Failure to follow
these instructions may result in result in damage, serious injury or death.
In Canada, the first
3 ft (915 mm)
of vent piping must be readily accessible for inspection.
