INSTALLATION
21
You must be able to read the
information
on
the
rating
plate.
Remember you may have to take the
entire water heater out later for
servicing.
The water heater is to be installed at
ground or floor level and must stand
vertically upright on a stable base as
acceptable to local authorities. The
base of the water heater is made of
corrosion resistant material, and it may
be placed directly in contact with the
supporting surface. It is not necessary
to allow for free air circulation under the
base of the water heater.
Note:
The water heater should not be placed in direct contact with a concrete
surface that is less than two months old and not fully cured as this may attack
the metal coating of the water heater base. A moisture barrier should be used
between the two surfaces in this instance.
Alternatively, a 050 and 080 model may be hung on a wall capable of taking the
weight of the filled water heater. A bracket kit is available from Rheem. Refer to
the instructions supplied with the kit.
Note:
If the base of the water heater is higher than the lowest hot water outlet by
2 m or more, the tank may be subject to a negative pressure (partial vacuum)
which can cause damage to the water heater cylinder. In this instance, an
approved vacuum break valve (RMC AV50A or equivalent)
must be
installed at
the highest point in the hot water line. Damage to the cylinder caused by incorrect
installation is not covered by the Rheem warranty.
Remember all local authorities have regulations about putting water heaters into
roof spaces.
SAFE TRAY
Where damage to property can occur in the
event of the water heater leaking, the water
heater must be installed in a safe tray.
Construction, installation and draining of a safe
tray must comply with AS/NZS 3500.4 and all
local
codes
and
regulatory
authority
requirements. AS/NZS 3500.4 also has
particular requirements when a safe tray must
be installed.
