INSTALLATION
WATER HEATER LOCATION
The water heater should be installed close to the most frequently used outlet
and its position chosen with safety and service in mind. Make sure people
(particularly children) will not touch the flue terminal. The flue terminal must be
clear of obstructions and shrubbery.
Clearance
must
be
allowed
for
servicing of the water heater. The
water heater
must be accessible
without the use of a ladder or scaffold.
Make sure the temperature pressure
relief valve lever is accessible and the
access cover, top panel and burner
can
be
removed
for
service.
Remember you may have to remove
the entire water heater later for
servicing.
The water heater is to be installed at ground or floor level on a stable fireproof
base as acceptable to local authorities. The water heater must also stand
vertically upright with the back of the water heater against or within 25 mm of
an external wall or alternatively against a fireproof screen extending at least
500 mm above, below and either side the flue terminal. Failure to observe this
precaution can cause problems in high wind areas.
Alternatively, the water heater may be installed partially recessed into an
external wall. A flashing kit for a recessed installation is available from Rheem.
"Flashing Kit"
Refer to
on page 27.
A secondary flue is not required.
It is a requirement of AS 5601 and AS/NZS 5601.1 to secure the water heater
to the wall. The top of the unit is to be secured to the wall or screen using the
wall bracket provided. Use the M6.5 masonry anchor provided only if it is
suitable for the wall or screen type. Otherwise select and use an alternative
"Wall Bracket"
fastener suitable for the application. Refer to
on page 27.
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.
