MAINTENANCE INSTRUCTIONS
As with all vents, the DuraSeal vent system should be inspected at least
an nually for the presence of deposits or debris and any accumulation
should be removed. The vent system should also be inspected at regular
periods for signs of leakage of condensate or combustion products at any
joints.
If the vent system incorporates a drain hose from either a Drain length or a
Drain tee cap, the hose must be inspected periodically to ensure that water
is in the trap loop. If a proper trap loop is not maintained, exhaust from the
connected appliances may accumulate in the building area.
