D. MAINTAINING THE CONDENSATE SYSTEM
The condensate trap assembly MUST BE PROPERLY INSTALLED according to these instructions when operating the boiler.
Operating the boiler without the condensate trap assembly will cause flue gases to leak and result in serious personal injury or death.
When servicing is complete, make sure the condensate collector
cap is replaced securely. Failure to do so will cause venting issues
that will result in serious injury or death.
1. Ensure the boiler is powered off and has had time to cool.
2. Remove the hose clamp attaching the condensate trap to the
condensate hose from the heat exchanger. Remove the clear plastic
hose from the hose barb. Remove the condensate hose clamp to
detach the condensate trap from the drain tube. Remove the
condensate trap from the boiler.
3. Remove the bottom cap from the condensate trap.
4. Flush trap with fresh water to remove debris from the trap.
NOTE: Ensure the float moves freely within the trap. If the float does
not move, DO NOT reinstall the trap.
5. When the condensate trap is sufficiently clean, reinstall the bottom
cap on the trap.
NOTE: Ensure all parts shown in Figure 35, Condensate Detail, are
installed with the condensate trap. If any parts are missing, DO NOT
reinstall the trap. Replace the entire assembly.
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. Install the condensate trap on the condensate hose from the heat
exchanger. Use the hose clamp to secure the trap. Attach the clear plastic hose onto the hose barb. Reinstall the condensate hose
clamp to detach the condensate trap from the drain tube.
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.
8. 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.)
9. 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 ¾”. To prevent sagging and maintain pitch, condensate piping should
be supported with pipe supports, and pitched ¼” per foot to allow for proper drainage.
