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 874 series water heater is installed. This will
keep the water temperature below 50°C – AU or 55°C – NZ at the bathroom and ensuite. The risk of scald
injury will be reduced and if no controllers are installed and the preset outlet temperature setting has not been
adjusted below 55°C or if a Kitchen controller is installed, still allow hotter water to the kitchen and laundry.
An 876 series water heater will not deliver temperatures exceeding 50°C, in accordance with AS 3498. There
is no need to fit a temperature limiting device to satisfy the requirements of AS/NZS 3500.4, if an 876 series
water heater is installed in an application where 50°C is the maximum permissible hot water temperature at
the outlet of a sanitary fixture used primarily for personal hygiene purposes.
SAFETY
This water heater is supplied with temperature sensors, a FlameSafe
®
protection system 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.
If the power supply cord or plug is damaged, it must be replaced by a qualified person in order to avoid a
hazard. The power supply cord and plug must be replaced with a genuine replacement part available from
Rheem. Phone Rheem Service or their nearest Accredited Service Agent / Centre to arrange for an inspection.
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.
WARNINGS

and the capabilities to do so.
 This water heater is not intended to be operated by persons with reduced physical, sensory or mental
capabilities i.e. the infirm, or by children. Children should be supervised to ensure they do not interfere
with the water heater.
 The water heater uses 240 Volt AC electrical power for operation of the control systems and the
combustion fan. The removal of the front panel will expose 240 V wiring. It must only be removed by a
qualified person.
 The power lead from the water heater must be plugged into a weatherproof electrical outlet. Take care
not to touch the power plug with wet hands.
 For continued safety of this water heater it must be installed, operated and maintained in accordance with
the Owner’s Guide and Installation Instructions.
 Do not modify this water heater.
 Do not use or store flammable materials in or near this water heater.
Flammable liquids (such as petrol), combustible materials (such as
newspapers) and similar articles must be kept well away from the water heater
and the flue terminal.
 Do not spray aerosols in the vicinity of this water heater while it is in operation.
Gases from some aerosol sprays become corrosive when drawn into a flame.
 Do not store swimming pool chemicals, household cleaners, etc., near the
water heater.
 Do not place articles on or against this water heater, or in contact with the flue
terminal. Ensure the flue terminal is not obstructed in any way at any time.
 Do not use Propane / Butane gas mixtures in a Propane model. A Propane model is designed to operate
on Propane only. The use of Propane / Butane mixture, such as automotive LP gas fuel, in a Propane
model is unsafe and can cause damage to the water heater.
Note: LP gas models sold in New Zealand are designed to operate on the Propane / Butane mixture
supplied in New Zealand. An LP gas model has an LFZ suffix in its model number.
