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.
The water heater has a frost protection system to protect against damage by preventing ice forming in the
waterways of the water heater, in the event of freezing conditions occurring. The frost protection system
will be rendered inoperable if electrical power is not available at the water heater. If it is necessary to
switch the power off to the water heater and there is a risk of freezing, then it is necessary to drain the
water heater. Refer “Frost Protection” on page 11 and to “Draining the Water Heater” on page 13.

Mains pressure water supply
The water heater is designed to operate at mains pressure by connecting directly to the mains water supply.
The maximum mains water supply pressure for the water heater is 1,000 kPa. If the mains supply pressure in
your area exceeds 1,000 kPa, an approved pressure limiting valve that does not have non-return valve
characteristics (such as an RMC PSL series valve) must be installed.
A minimum water supply pressure of 120 kPa is required to achieve the rated flow and performance of the
water heater.
Refer to “Mains Water Supply” on page 52 for additional information.
Mounting of the water heater
This water heater must be installed vertically upright with the water, gas and power connections on the
underside, pointing toward the ground. The back of the water heater can be either against a wall or supported
by a frame. The water heater must be well secured to the wall or frame using two fasteners, suitable for the
wall or frame type, each at the top and bottom of the unit. Refer to the note on page 50 for additional
information.
Alternatively the water heater can be installed recessed into a wall, using a proprietary made recess box from
Rheem for such an installation. Refer to the installation instructions which accompany the recess box kit for
the dimensions of the space required and information on its installation. Refer also to “Recess Installation” on
page 52.
