INSTALLATION
Preparations
Note
Ensure that the temperature knob will be accessible from
the front when the appliance is secured in place.
The appliance is designed to be permanently wall-mounted to a
solid surface. Ensure the wall offers adequate load bearing ca-
pacity. Consult the specification table for the filled weight of your
appliance.
There should be a suitable drain near the appliance to drain off
water in the case of activation of the T&P relief valve.
Always install the appliance vertically in a room free from the risk
of freezing and as close as possible to the draw-off points.
The appliance may not be fitted in a corner since the screws for
fixing the appliance to the wall must remain accessible.
10.2 Securing the plywood backing sheet
This procedure calls for mounting a ¾˝ plywood sheet to the wall
attaching to at least 3 wooden studs, or another wall surface using
comparable means. Mount the appliance to the plywood sheet
using ½˝ diameter fasteners.
f
Transfer the dimensions for the holes to be drilled on the ply-
wood sheet (see chapter 16.1, “Dimensions and connections”,
pg. 11).
f
Drill a hole in the plywood to fit the ½˝ tee nuts into the back
side of the sheet. Thread the ½˝ bolt and washer into the tee
nut, leaving a gap for the tank to mount on.

f
Find the wall studs and mark their location. This is the most
secure means of mounting the sheet on the wall.
f
Secure the plywood sheet to the studs with screws at least
size #10 x 2½˝ long. Space the screws every 6˝ above the
location of the tee nuts, and every 12˝ below. Use a level to
align the sheet horizontally.
f
It is recommended to mount the plywood onto 2x6 studs, but
an installation on 2x4 studs is acceptable if mounted to at
least 3 studs. If studs are spaced farther apart than 16˝, use
a wider plywood sheet and make sure to mount to at least 3
studs.

10.3 Mounting onto the plywood backing sheet
The mounting bracket attached to the appliance has hook-in slots.

the washers are on the outside of the mounting bracket.
