Installation / Operation Instruction Manual

SECTION VIII

MAINTENANCE

This indirect-fired water heater 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 and Pressure Relief Valve (Annual) – The

temperature and 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 capacity 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 and pressure 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.
