GENERAL MAINTENANCE
The jacket of the water heater can be cleaned with a soft cloth and warm mild soapy water. Under no
circumstances should abrasive materials or powders be used.
Condensate Trap
A condensate trap may be installed as part of a condensate drain line from the secondary flue system.
Regularly check a condensate trap, if one is installed, to ensure it is filled with water. If a trap is dry or the
water level is low, then a trap must be refilled.
To check and / or refill a trap with water, remove the clamp securing the hose of the condensate trap to the
spigot on the flue outlet. Remove the hose from the spigot and fill the condensate trap with water. Reconnect
the hose to the spigot. Ensure the hose is not kinked when reconnected.
Warning: Failure to fill a Condensate Trap with water may cause flue gases to escape through the drain
line.
