Exhaust Collector Removal, Inspection & Replacement
The Exhaust Collector Gasket seals around the secondary flue tubes and between the jacket
and the collector cover. This seal allows the exhaust to be concentrated into a single
exhaust port and allows a passageway for the condensate to flow into the trap.
If condensate is dripping from the seal or if a measured reduction in blower pressure is
observed, the gasket may need inspection. To do this, follow the steps listed below.
1. Loosen the hose clamp connecting the condensate tee to the exhaust cover.
2. Remove the ¼” clear hose from the port on the exhaust cover.
3. With a 5/16” socket or wrench, loosen the 8 screws
sealing the cover to the gasket.
4. Remove the cover and inspect the seal bead on the
gasket flange as well as the seal around the secondary
flue tubes. Inspect the gasket to make sure there are
no cuts or openings in the balance of the gasket body.
5. If the gasket requires replacement, follow the steps
below:
a. Remove the gasket from the studs extending through the jacket. The gasket flange
should be aligned such that the studs extend through the flange holes.
b. Pull the gasket off the secondary flue tubes.
c. Replace the gasket with the new gasket by first pushing the gasket over the secondary
flue tubes. This can be done by hand and should be pushed over the secondary flue
discharge such that the neck of the opening should be flush with the end of the
secondary flue tube.
