EcoKing C200 - Mandatory Pre-Commissioning Procedure for Plastic Venting; Vent;Air-Intake Pipe Length Determination

Part 4 - General venting
Warning
The concentric vent pipe should extend fully into the appliance flue outlet adapter / air intake adapter. Make sure
the concentric vent pipe extends in the appliance on the adapter location as shown in the figure underneath.
Ensure that the venting system does not apply a load or strain on the appliance flue outlet adapter.

Warning
Warning
In Canada, the first piece of vent piping must be readily
accessible for inspection.
Exhaust venting must be supported to reduce strain on piping joints. Failure
to follow these instructions may result in damage, serious injury or death.
Mandatory Pre-commissioning Procedure for Plastic Venting
Warning
1) Working with the power turned off to the appliance, completely install the concentric vent and air intake system.
2) Maintain the appliance gas supply shut-off valve in the off position.
3) Disconnect electrical leads. Ensure the cables are placed in a fashion where they will not arc to ground or
other conductor.
Vent/Air-Intake Pipe Length Determination
Use table 4.3 to determine the maximum pipe length that can be used. The table calculates pipe length with regard
to use of 90º elbows, and 45º elbows. Allowable pipe lengths for vent and air-intake pipes are shown for Natural
Gas.
