WARRANTY
Alliance continuous flow gas water heaters models R26N, R26P
WATER SUPPLY QUALITY
This water heater must be connected to water of a quality within the limits described
below to be covered by the warranty.
This water heater is manufactured to suit the water conditions of most public reticulated
water supplies. However, there are some known water chemistries which can have
detrimental effects on the water heater and its operation and / or life expectancy. If you are
unsure of your water chemistry, you may be able to obtain information from your local water
supply authority.
CHANGE OF WATER SUPPLY
The changing or alternating from one water supply to another can have a detrimental effect
on the operation and / or life expectation of a heat exchanger in a continuous flow water
heater.
Where there is a changeover from one water supply to another, e.g. a rainwater tank supply,
bore water supply, desalinated water supply, public reticulated water supply or water brought
in from another supply, then water chemistry information should be sought from the supplier
or it should be tested to ensure the water supply meets the requirements given in these
guidelines for warranty to apply.
SATURATION INDEX
The saturation index (SI) is used as a measure of water’s corrosive or scaling properties.
In a corrosive water supply, the water can attack copper parts and cause them to fail.
Where the saturation index is less than –1.0, the water is very corrosive and warranty does
not apply to a copper heat exchanger in a continuous flow water heater.
In a scaling water supply calcium carbonate is deposited out of the water onto any hot
metallic surface. Where the saturation index e0.80, warranty does not apply to a
copper heat exchanger in a continuous flow water heater.
Water which is scaling may be treated with a water softening device to reduce the saturation
index of the water.
WARRANTY CONDITIONS
1. The water heater must be installed in accordance with the water heater installation
instructions, supplied with the water heater, and in accordance with all relevant statutory
and local requirements of the State in which the water heater is installed.
