Do not install the condensate assembly if a component is lost or missing. Replace the entire assembly. Failure to follow this warning
could result in property damage, serious personal injury, or death.
6. Fill the condensate trap with fresh water prior to reassembly on the boiler.
7. Slide the condensate trap adapter onto the drain tube until the holes line up with the groove.
8. Insert stainless steel hitch pin to lock condensate adapter to the drain tube.
9. Reattach the clear plastic hose to the hose barb.
Do not operate the boiler without the clear hose attached from the hose barb to the pressure switch. Failure to follow this warning could
result in property damage, serious personal injury, or death.
10. If a condensate neutralizer kit is installed with the boiler, check the assembly when cleaning the condensate trap, and replenish the
limestone chips if necessary. When replacing the limestone chips, take care to ensure chips are
no smaller than ½” to avoid blockage in
condensate piping (for piping details, refer to condensate neutralizer installation instruction.)
11. Check condensate piping for sagging and/or leakage. Repair any sags or leaks before restoring power to the boiler.
It is very important that the condensate piping be no smaller than ½”. To prevent sagging and maintain pitch, condensate piping should
be supported with pipe supports, and pitched ¼” per foot to allow for proper drainage.
The condensate line must remain unobstructed, allowing free flow of condensate. If condensate freezes in the line, or if line is
obstructed in any other manner, condensate can exit from the tee, resulting in potential water damage to property.
12. If the boiler has a condensate pump, ensure the pump operates properly before considering maintenance complete.
