Mandatory Pre-commissioning Procedure for Plastic Venting
Do not apply power to the appliance prior to Step 4 in the Mandatory Pre-commissioning
Procedure for Plastic Venting.
1) Working with the power turned off to the appliance, completely install the vent and air intake system,
securely cementing joints together. If possible, allow primers/cements to cure for 8 hours before firing the
burner. If curing time is less than 8 hours, proceed with Steps 2 through 6.
2) Maintain the appliance gas supply shut-off valve in the off position.
3) Disconnect electrical leads to the Hot Surface or Spark Igniter. Ensure the cables are placed in a fashion
where they will not arc to ground or other conductor.
Spark Igniter Cable - Maintain a minimum 2” separation between spark igniter circuit and
conductors. Failure to follow instructions may result in component failure, injury or death.
4) Turn power on to the appliance and apply a heat demand.
5) Allow for 3 complete trials for ignition, consisting of pre and post purge of the combustion blower, until an
ignition lockout occurs. Repeat the process two more times (i.e. 9 complete ignition sequences in total).
6) Turn power off and reconnect the electrical leads to the Igniter.
Vent/Air-Intake Pipe Length Determination
Use Table 4-4 to determine the maximum pipe length that can be used. The table calculates sweep, 90º elbows,
and 45º elbows at 5 equivalent feet [1.52 m] each. Allowable equivalent pipe lengths for vent and air-intake pipes
are shown separately for Natural Gas and LP. Length calculations need not include the three 90
°
elbows of the
exterior vent piping (two outlet, one inlet).
Example: An Lx200 can be installed with 105 equivalent feet [32 m] of air-intake piping and 105 equivalent feet
[32 m] of vent piping when operating with Natural Gas. When operating with Propane Gas (LP), the maximum
vent length in equivalent feet is limited to 50’ (3” pipe). Maximum equivalent feet may vary depending on model
number and vent pipe size (.i.e. 30’ with 4” pipe and 65’ with 6” pipe). Note, the Lx800 operates on Natural Gas
only; therefore, no pipe lengths are specified for Propane. See Table 4-4 for more details.
The length of one vent pipe (intake or exhaust) may not exceed the length of the other
vent pipe by more than 20 equivalent feet (6.1 m).

Notes
1
Only 6” exhaust vent is permissible for the Lx800. Air intake pipe can be 4” or 6” (6” is recommended).
2
Model Lx800 operates with Natural Gas only.
Venting Options
Venting systems include direct vent (two-pipe), concentric vent, and indoor combustion air for side-wall or roof
terminations. Options are model dependent. See Figures 4-4 to 4-8 for Options and Figures 4-12 to 4-14 for Kits.
PVC In Canada - Safety authorities in some jurisdictions are not allowing PVC venting
materials with appliances of any kind, even if System 636 certified. Check with the local
safety inspector to verify compliance prior to installing a PVC Concentric Vent Kit with a Trinity Lx appliance.
Venting Options - Due to potential moisture loading (build-up) along the exterior wall,
sidewall venting may not be the preferred venting option. See Figs 4-4(b), 4-5(b), 4-8 (b).
