MAINTENANCE
The Single-wall Indirect is intended to provide a service life of many
years. Components that require service, however, may be subject
to failure. Failure to use the correct procedures or parts in these
circumstances may make the water heater unsafe.
The owner should arrange to have the following inspections and
simple maintenance procedure performed by qualified service
personnel at the frequencies suggested.
1. Boiler and Domestic Water Piping (Annual) – Check all
piping for signs of leakage at joints, unions, and shut-off
valves. Repair as needed.
2. Temperature-Pressure Relief Valve (Annual)- The
temperature-pressure relief valve should be checked to ensure
that it is in operating condition. To check the relief valve, lift
the lever at the end of the valve several times. The valve
should seat properly and operate freely. If water does not
flow, remove and inspect for obstructions or corrosion.
Replace with a new valve of the recommended size as
necessary. Do not attempt to repair the valve, as this could
result in improper operation and a tank explosion. In areas
with poor water conditions, it may be necessary to inspect the
temperature-relief valve more often than once a year.
CAUTION
Before manually operating the valve, make sure that a
drain line has been attached to the valve to direct the
discharge to an open drain. Failure to take this
precaution could mean contact with extremely hot water
discharging from the valve during this checking
operation.
