ANNUAL start-up by qualified service
technician
Obtain an Inspection and service kit (see “Replacement parts,”
page 39) before attempting to perform the annual start-up.
This kit contains items that will usually have to be replaced.
Check water supply temperature at several outlets to ensure
the water temperature is acceptable for intended use and
that all temperature control devices are functioning properly.
Read page 3 and verify that all requirements are met by the
installation.
Perform the following procedures:
❏ ❏ Perform any procedures required by local codes.
❏ ❏ Verify system pressure both on domestic water and
boiler water sides.
❏ ❏ Manually operate T&P relief valve at least once
a year (see Figure 21). This will release some hot
water. Move operating lever to open position for
a few seconds and then move it back, allowing it
to snap closed. After T&P relief valve is operated,
if it continues to release water, close cold water
inlet to water heater immediately. Follow draining
instructions, and replace the T&P relief valve. If
T&P relief valve weeps periodically, it may be due
to thermal expansion. Install an expansion tank if
not already installed.
❏ ❏ Follow instructions on circulator to oil it, if oil-
lubricated.
❏ ❏ Follow instructions in “Inspect anode and water
heater interior,” page 26.
❏ ❏ Check valves, pipes and fittings for leaks.
❏ ❏ Check function of all controls and valves (see con-
trol manufacturer’s instructions).
❏ ❏ Review homeowner’s maintenance responsibilities
Figure 21 T&P valve operation
Before operating the T&P relief
valve, make sure no one is in front of
or around the T&P relief valve dis-
charge piping. Hot discharge water
can cause severe personal injury or
substantial property damage.
Plugging T&P relief valve or dis-
charge piping can cause excessive
pressure in the water heater, result-
ing in severe personal injury, death
or substantial property damage.
