SERVICING SECTION 6

Servicing must be carried out by a properly qualified person.
Whilst giving these instructions for the care of the Heater, it is recommended that checks
are carried out by the installer or local gas authority, at least annually. Ensure good
ventilation by keeping the heater free of extraneous materials and clear of dust and lint.
Keep pipework, flue and tops of heaters clear of any combustible materials. A water
softener or lime inhibitor should be employed in hard water areas. The heater should be
inspected every few months via the hand hole cleanout and lime or silt deposits removed.
Failure to do so will shorten heater life and may invalidate the warranty.
NOTE! The cleanout hole gasket must be renewed whenever the cover is removed.
Before servicing, carry out the following operations.
1) Turn off the gas service cock.
2) Turn off the cold water supply to the heater.
3) Turn on the hot water draw-off taps served by the water heater, or, for multiple
installations, turn off the hot water outlet connection valve and secondary return valve.
4) Drain down using the drain valve on the heater.
Annual checks of the ignition systems, temperature controls and any other controls are
necessary to ensure continued safe and efficient operation.
The entire combustion system must be sealed for this water heater to function correctly.
Ensure that the burner access panel is kept tightly sealed. The combustion air supply pipe
at the rear of the heater must be tightly clamped to the vent adopter and combustion air
box boot. Replace any damaged parts.
The entire venting system and combustion air supply must be inspected at least annually
for integrity of all joints and gaskets.
BLOWER MOTOR BEARINGS
Every six months lubricate the blower motor bearings. Apply four drops of SAE 20 motor
oil to the ports of the front and rear motor bearings.
