Section 5: MAINTENANCE
5.1 INTRODUCTION
Regular water heater maintenance will ensure
trouble-free service for many years. It is
recommended that you set up and follow a
maintenance program. All component may fail
eventually. The use of incorrect replacement
parts or disregarding safety procedures and
warnings during repairs may reduce the boiler
safety level and shorten its useful life.
The owner should set up the following
maintenance program.
5.2 AT ALL TIMES
The water heater should be immediately
inspected in case of:
Overheating or burn plastic odours are
detected.
Water leak from the water heater or the
domestic hot water system is found.
If the hot water is leaking from the pressure relief
valve, it may indicate a problem with some
components of the systems. Immediate attention
and repair by a qualified technician are required.
NEVER CLOSE OR PLUG A PRESSURE
RELIEF VALVE.
5.3 YEARLY INSPECTION
Make sure that the power supply to the water
heater has been turn off at the circuit breaker
before attempting any work on the water
heater.
Visual inspection of the water heater
electrical cabinet. Checks for leaks at the heating
elements, sign of overheating of electrical
components and wiring. Check for t proper
operation of the unit temperature control.
Check the thermostatic mixing valve
proper operation by measuring domestic water
temperature at a domestic hot water tap with a
thermometer.
Check for proper operation of the
automatic air vent, located on top of the water
heater, by removing its cap and by pressing on
the knob, releasing air until water began to be
expelled.
Do not open the tank drain tap unless
repair to the water heater is required. Opening
the drain tap will eventually force fresh water into
the tank. This water will introduce oxygen diluted
in the fresh water. This oxygen will cause
corrosion of the tank internal surfaces, damaged
the reservoir and void the warranty.
If repair is required, it should be
accomplished as soon as possible, by a qualified
technician and using genuine replacement parts.
The manufacturer’s warranty DOES NOT
cover
problems
caused
by
improper
installation or maintenance. If the safety valve
opens periodically, it may be due to the
expansion tank. Immediately call a qualified
technician to appraise and repair the problem.
