Kelvinator Gas Continuous Flow hot water system for the plumber 5
For the plumber
PLEASE NOTE this water heater is supplied factory set to
comply with the requirements of AS 3498.
If you are installing a 60°C or 70°C gas continuous flow hot
water system, a tempering valve is to be installed for the
hot water supplying sanitary fixtures primarily used for the
purpose of personal hygiene.
Please follow all the installation instructions in this manual
including the following instructions regarding the water
heater outlet connection:
1. When connecting the hot water supply to the fixtures in
the property, a minimum of three (3) metres of pipework
must be used between the outlet of the water heater and
the first tap or outlet. If you are installing a 60°C or 70°C
model, only a minimum of one (1) meter of pipework is
necessary. See diagram to the right.
2. The hot water outlet line from the water heater should be
covered with 20mm pipe insulation or similar to prevent
heat loss and persons coming in contact with it.
3. When the installation is completed, the temperature of
the hot water supplying sanitary fixtures primarily used
for the purpose of personal hygiene, for example the
bathroom shower/taps, shall be checked to ensure it does
not exceed 50°C. If a 50°C model gas continuous flow hot
water system has been installed, all hot water taps and
fixtures need to be checked to ensure they do not
exceed 50°C.
