GENERAL WIRING DIAGRAM

HEATER MOUNTING INSTRUCTIONS

The water heater should be installed close to a water drainpipe so that excess water from
the safety relief valve can drain away without harm; this drain pipe should always be kept
free of obstruction.
Fix the mounting bracket supplied with the heater to the wall; see below for dimensions
of the holes required; always use screws that are suitable for the wall material and the
weight of the heater otherwise the heater may pull the bracket o the wall.
Hang the water heater on the bracket.
Tug downwards on the heater to ensure that both “fingers “of the bracket are seated in
the mounting slots.

The heater can also be stood on its base using the rubber feet provided for this purpose.
Attach the four adhesive feet to the base of the heater before plumbing.

Confirm water piping orientation before wall mounting.

Note: If using the rubber feet, it is not neces­sary to use the wall bracket also.
Should the installer wish to use the bracket as
an additional xing method, conrm location
of bracket with feet attached to heater prior to

installation.
