INSTALLATION – WATER HEATER
THIS WATER HEATER IS FOR OUTDOOR INSTALLATION ONLY.
THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING.
Check the water heater is suitable for the gas type available.
(refer to the rating label on the water heater)
The 874 series of water heater may be installed as an in-series gas booster water heater to a solar preheat
water heater. For information relating to the function and operation of the solar water heater, refer to the
Owner‟s Guide and Installation Instructions supplied with the solar water heater.
The installation must comply with these installation instructions and with the requirements of Standards
AS/NZS 3500.4, NZS 5261 or AS/NZS 5601 and all local codes and regulatory authority requirements.
All packaging must be removed from the water heater prior to its 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. If this water heater is part of a solar water heater system, it should also be
installed close to the solar storage tank. Make sure people (particularly children) will not touch the flue
terminal. The flue terminal and air inlet 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 entire front panel can be removed for
service. 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.
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 secured to the wall
or frame using suitable mounting screws, two each at the top and
bottom of the unit (refer to page 49 for mounting hole positions).
Alternatively the water heater can be recessed into a wall (refer to
"Recess Installation"
on page 43).
For a single water heater installation, refer to the diagram on page 52.
The water heater must not be installed in an area with a corrosive atmosphere where chemicals are stored or
where aerosol propellants are released. Remember the air may be safe to breathe, but when it goes through
a flame, chemical changes take place which may attack the water heater.
A secondary flue is not required. The water heater must not be installed indoors or in a confined space.
