Section 6 : MAINTENANCE
6.1 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 components 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.
6.1 AT ALL TIMES
The boiler should be immediately inspected in
case of:
Overheating or burn plastic odours are
detected.
Water leak from the boiler or the space
heating system is found.
If the hot water is leaking from the boiler pressure
relief valve, it may indicate a problem with some
components of the space heating system or the
domestic hot water system. Immediate attention
and repair by a qualified technician are required.
NEVER CLOSE OR PLUG A PRESSURE
RELIEF VALVE.
6.2 EVERY 6 MONTHS
Check
automatic
air
vent
proper
operation.
Using hand operated air vent installed on
the heating system radiators or in other
location, bleed air from the heating
system.
6.3 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. Check for leaks at the
heating elements, sign of overheating of
electrical components and wiring. At the
beginning of the heating season, check
for proper operation of the boiler
controller, circulating pump(s), mixing
valve for low temperature heating system,
room thermostat(s) and other heating
system components for proper operation.
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
introduces oxygen diluted in the fresh
water. This oxygen will cause corrosion of
the tank internal surfaces, damage the
reservoir and void the warranty.
If repair is required, it should be
accomplish 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.
