Before You Begin
Locate the paper mounting-hole template packed with the heater.
Read the installation and operating instructions completely.
Decide whether to install with concealed or exposed plumbing and/or electrical
connections. Concealed connections are preferred for superior appearance.
Step 1 – Positioning
Position the heater so the tap will drain on to a draining board or drip tray.
Position the base of the tap to be not less than 200mm above the draining
board (height should be increased only if essential for filling larger vessels).
Provide clearance for service access of not less than 150mm top, 65mm left,
20mm right.
Mark corner positions for the heater on the wall so as to position the paper
mounting-hole template.
Step 2 – Fastening
Position mounting-hole template on wall and drill holes where shown.
Drill holes for water inlet, vent outlet and wiring if rear access is intended.
Remove cover fastening screws (as shown below) from heater and lift whole
cover off heater.
Install plumbing and wiring and prepare pipe ends and wiring ends as shown.
Screw heater chassis to the wall using the supplied fixings, ensure the fixings
are suitable for the substrate. If not supply your own suitable fixings.
Ensure the mounting surface is capable of supporting the weight of the filled
unit, fixings must be capable of supporting the heater weight when filled. See
Product specifications for filled weights.

b. Electrical supply.
A standard 13 amp double pole fused spur on the wall within 1500mm of
the heater.
Isolation switches must have a contact separation of at least 3mm in all poles.
The circuit should be protected by a suitably rated RCD.
The electrical installation should comply with current IEE regulations and
any Local Authority requirements.
c. A potable cold water supply with a minimum working pressure of 0.07
MPa (0.7 bar) and a maximum working pressure of 0.7 MPa (7 bar)
connected via an isolation valve.
d. Outlet drainage to a sink draining board or to a drip tray.
e. Access to drainage from a vent situated at the base of the heater.
f. If the water pressure is likely to exceed 0.7 MPa (7 bar), a 0.35 MPa
(3.5 bar) pressure reducing valve must be installed in the cold water
supply line.
g. In all installation instances the walls of the heater must be vertical and the
base horizontal, there can be no exceptions to this rule.
