How Long Will the Water Heater Last
The water heater is supported by a manufacturer’s warranty (refer to page
31). There are a number of factors that will affect the length of service the
water heater will provide. These include but are not limited to the water
chemistry, the water pressure, the water temperature (inlet and outlet) and
the water usage pattern.
Precautions
Where damage to property can occur in the event of the water heater
leaking, the water heater must be installed in a safe tray. Construction,
installation and draining of a safe tray must comply with AS/NZS 3500.4
and all local codes and regulatory authority requirements.
The water heater must be maintained in accordance with the Owner’s
Guide and Installation Instructions. Refer to “Periodic Maintenance” below.
If this water heater is to be used where an uninterrupted hot water supply is
necessary for your application or business, you should ensure that you
have back up redundancy within the hot water system design. This should
ensure the continuity of hot water supply in the event that this water heater
was to become inoperable for any reason. We recommend you seek advice
from your plumber or specifier about your needs and building back up
redundancy into your hot water supply system.
Periodic Maintenance
Minor Six Monthly Maintenance
It is recommended minor maintenance be performed every six months by
the dwelling occupant.
Warning: Exercise care when operating easing levers as water
discharged from the water heater may be of a very high temperature.
Minor maintenance actions:
1. Operate easing lever on pressure temperature relief valve (refer to
“Pressure Temperature Relief Valve” on page 9).
2. Operate easing lever on expansion control valve (if ECV fitted) (refer
to “Expansion Control Valve” on page 10).
3. If an overflow tray is installed, check to ensure the overflow tray drain
pipe is not blocked.
