ABOUT YOUR WATER HEATER
5
MAINS PRESSURE
The water heater is designed for direct connection to the mains water supply. If the mains supply pressure in
your area exceeds that
shown on page
15, a pressure limiting valve must be fitted. The supply pressure should
be greater than 140 kPa for the rated flow and performance to be achieved.
Note:
It is not recommended this water heater be installed with a low pressure water supply.
REDUCED HOT WATER FLOW WHEN HEAT EXCHANGER IS COLD
At a cold start-up, i.e. when the water heater has not operated for some time (which is most often first thing in
the morning), the initial flow of hot water may be reduced for a period of 5-10 seconds while the heat exchanger
warms up.
This is both an energy and water saving feature of this water heater.
Once the heat exchanger
has warmed up the hot water flow will increase and remain at normal flow levels. This feature will only occur
at a cold start-up and not when the heat exchanger is already warm from a recent use of hot water.
HOW HOT SHOULD THE WATER BE?
The water heater heats the water to the preset outlet temperature setting.
The factory preset outlet temperature setting of the 834 series water heater
is 60°C.
Note:
The preset outlet temperature setting of this water heater cannot be
adjusted by the householder. The setting can only be adjusted by the
installer, Rheem Service or their nearest Accredited Service Agent.
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
This water heater can deliver water at temperatures which can cause
scalding. Check the water temperature before use, such as when entering a
shower or filling a bath or basin, to ensure it is suitable for the application
and will not cause scald injury.
We recommend and it may be required by regulations that an approved
temperature limiting device be fitted into the hot water piping to the bathroom
and ensuite when an 834 series water heater is installed. This will keep the
water temperature below 50°C at the bathroom and ensuite. The risk of scald
injury will be reduced and if the preset outlet temperature setting has not
been adjusted below 60°C, still allow hotter water to the kitchen and laundry.
SAFETY
This water heater is supplied with a temperature sensor, over-temperature cut-off device and a pressure relief
valve. These devices must not be tampered with or removed. The water heater must not be operated unless
each of these devices is fitted and is in working order.
The Rheem warranty may not cover faults if relief valves or other safety devices are tampered with or
if the installation is not in accordance with these instructions.
