3.3 Installing the boiler
The appliance must be installed
exclusively on a plumb, vertical solid wall
capable of supporting its weight.
■ The boiler should be fitted within the building
unless otherwise protected by a suitable
heated enclosure i.e. garage or outhouse.
(The boiler may be fitted inside a cupboard)
■ It is recommended to always leave the
ON/OFF switch always in ON position to give
frost protection.
■ If the boiler is installed in a room containing a
bath or shower reference must be made to the
relevant requirements.
■ Appliance is approved for installation on
combustible walls.
In order to allow access to the interior of the
boiler for maintenance purposes, it is important
that the minimum distances indicated in figure 1
are respected. To make the installation easier,
the boiler is supplied with a template to enable
the pipe connections to be positioned prior to
fixing the appliance to the wall.
To install the appliance, proceed as follows (see
fig. 2):
a.
Use a level (of not less than 24" long) to
mark a horizontal line on the wall where the
appliance is to be fitted.
b.
Position the top of the template along the line
drawn with the level, respecting the distances
indicated. Then mark the center position of
the two wall screws or anchors. Finally, mark
the positions of the water and gas pipes.
Position the boiler with consideration of the
venting requirements.
c.
Remove the template and install the
domestic hot and cold water pipes, the gas
supply pipe and the central heating pipes
using the fittings supplied with the unit.
Fix the boiler to the wall using the bracket and
connect the pipes.
