SAFETY AND WARNINGS
 This water heater is only intended to be operated by persons who have the experience or the knowledge
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.
 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 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.
 The water heater uses 220 - 240 V a.c. electrical power for operation of the control systems and the
combustion fan. The removal of the front panel will expose 220 - 240 V a.c. wiring. It must only be removed
by a qualified person.
 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.
The Rheem warranty may not cover faults if safety devices or the relief valve are tampered with or
if the installation is not in accordance with these instructions.
 Temperature controllers must not be fitted to this water heater (874 series) if it is installed as an in-series
gas booster with a solar water heater system because water at a temperature much higher than the
controller setting can be delivered. If a solar water heater is installed to an existing water heater
installation, then all controllers must be disconnected and removed.
 For continued safety of this water heater it must be installed, operated and maintained in accordance with
the Owner’s Guide and Installation Instructions.
 Servicing of the water heater must only be carried out by qualified personnel. Phone Rheem Service or
their nearest Accredited Service Agent / Centre.
 Do not modify this water heater.
 Switch off the electrical supply at the power outlet to the water heater prior to performing general
maintenance. This will prevent the water heater from operating while you clean or spray around the water
heater. Refer to “General Maintenance” on page 12 for additional information.
 Do not spray aerosols in the vicinity of this water heater while it
is in operation. Propellants and gases in many aerosol sprays
contain hydrocarbons which are flammable. Gases from aerosol
sprays may also become corrosive when drawn into a flame.
 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 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.
