C. 6 MONTH MAINTENANCE
Check Primary and Gas Piping

Remove the water heater cover and perform a gas leak inspection following Operating Instructions, page 2, this manual. If gas
odor or leak is detected, follow procedures on page 2. Call a qualified service technician.

Visually inspect for leaks around the internal water heater water connections and around the heat exchanger. Visually inspect
the external system piping, circulators, and system components and fittings. Immediately call a qualified service technician to
repair any leaks
Have leaks fixed at once by a qualified service technician. Failure to comply could result in substantial property damage, severe
personal injury, or death.
Operate Pressure Relief Valve

Before proceeding, verify that the relief valve outlet has been piped to a safe place of discharge, avoiding any possibility of
scalding from hot water.

Shut power off to the water heater. To avoid scalding, wait for water heater to cool before operating the relief valve.
To avoid water damage or scalding due to relief valve operation, a discharge line must be connected to the valve outlet and directed to
a safe place of disposal. This discharge line must be installed by a qualified service technician or heating/plumbing installer in
accordance with the water heater installation manual. The discharge line must be terminated so as to eliminate possibility of severe
burns or property damage should the valve discharge.

Lift the relief valve lever. If water flows freely, release the lever and allow the valve to seat. Watch the end of the relief valve
discharge pipe to ensure that the valve does not weep after the line has had time to drain. If the valve weeps, lift the lever
