MOUNTING THE BOILER
•
Due care should be taken when lifting the boilers,
with respect to their weights, see below.
W45 = 87kg
W60 = 88kg
W80 = 101kg
•
Lift the boiler onto the wall mounting plate as shown.
Note: It is not necessary to hold the boiler at an angle
to engage the wall mounting plate.
•
Using the remaining coach screw, secure the bottom
of the boiler to the wall through the attached bracket.
10 VENTILATION
The ventilation requirements of these boilers is dependant
on the type of flue system used, and their heat input. All
vents must be permanent with no means of closing, and
positioned to avoid accidental obstruction by blocking or
flooding.
W45, W60, W45P and W60P
Detail reference should be made to BS. 5440 Pt. 2. In IE
refer to the current edition of I.S. 813.
The following notes are for general guidance only:
If installed as a room sealed appliance in a room or internal
space, then no purpose provided ventilation is required.
If installed as an open flued appliance in a room or internal
space then a permanent air vent is required. The sizes
given below are for vents directly communicating with
outside air. For other situations refer to BS. 5440 Pt. 2. In IE
refer to the current edition of I.S. 813.

If installed in a compartment, then permanent air vents are
required at high and low level. These vents may
communicate direct to outside air, or to a room/internal
space. If to a room/internal space, it must itself be
adequately ventilated as above.

I.S.820. The following notes are for general guidance only:
If ventilation is to be provided by means of permanent high
and low vents communicating direct with outside air, then
reference can be made to the sizes below. For other
