5. Remove the DHW inlet filter. Then clean it with a toothbrush and clean running water. See Figure 56.
Figure 56
– Cleaning the Inlet Filter
6. Reinstall the DHW inlet filter.
7. Purge air from the DHW lines by opening a hot water faucet in the
system. When water flows freely, all air is purged.
8. Repeat the process on the CH inlet filter on the appliance.
9. Restore water service to the appliance by opening the isolation valves,
or turning on the main water valve.
10. Turn on the gas valve. Turn on electrical power to the appliance and
press the Power button to turn the appliance on.
11. Reinsert the filter and ensure the filter cap is securely tightened.
12. Connect electrical power to the appliance.
Maintaining the Condensate System
The condensate trap assembly MUST BE PROPERLY INSTALLED
according to these instructions when operating the appliance. Operating
the appliance 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 appliance 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 appliance.
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 57, Condensate Detail, are installed with the condensate trap. If any parts are missing, DO
NOT reinstall the trap. Replace the entire assembly.
