INSTALLLATION
IMPORTANT: When installing a new water heater to an existing system, it is a Raypak requirement
that the system and its equipment be inspected, drained and flushed with clean fresh water, before the
new water heater is connected.
Failure to do this may cause blockages and/or water heater damage which is NOT COVERED BY
WARRANTY.
WATER HEATER LOCATION
This water heater is suitable for installation indoors or outdoors with the correct flue configuration. The
water heater should be installed either close to the most frequently used outlets or with a circulated
flow and return system and its position chosen with safety and service in mind. Make sure people
(particularly children) will not touch the flue outlet. 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 pressure relief valve lever is accessible and the
front covers or panels, thermostats and burner can be removed for service.
Gas or water piping, electrical conduits, trees, fences, or other equipment, etc must not obstruct the
front or top of the heater.
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.
If a safe tray is required, it should be large enough for all the equipment and must not restrict
combustion airflow.
The water heater must be mounted on a level non-combustible base such as a concrete slab, concrete
plinth, steel plate etc. Raypak water heaters must not be installed on carpeting.
RAISED OR MESH PLATFORM
Water heaters installed on a raised platform must be installed on a
solid non-combustible base to prevent wind affecting the
performance of the water heater.
If steel mesh decking is used, a base of suitable non-combustible
material must be used to cover the mesh.
The base must extend 1m on all sides of the water heater.
HIGH WIND CONDITIONS
In areas where high winds occur frequently it may be necessary
to install a wind break so that the water heater is not subject to
direct wind gusts.
High rise or multi storey installations can present problems with
excessive winds and we recommend that the common practice of
surrounding the water heater within an open top enclosure be
adhered to.
