7.8 CONDENSATE DRAIN ASSEMBLY
KC Boilers contain a condensate drain cup
(Figure 2.6) which should be inspected and
cleaned annually to ensure proper operation.
To inspect and clean the assembly, proceed as
follows:
1. Remove the left side panel and left rear
cover to provide access to the condensate
drain components (see Figure 2.6).
2. Disconnect the drain hose attached to the
exhaust manifold.
3. Disconnect the plastic tubing from the
condensate cup drain tube to the drain
4. Remove the condensate cup from under the
unit. Thoroughly clean the cup and inspect
drain tube for blockage.
5. Check to ensure that the condensate drain
opening in the exhaust manifold is not
blocked.
6. Flush out the drain hose and plastic tubing.
7. After the above items have been cleaned
and inspected, reassemble the condensate
drain components by reversing the previous
steps.
