MOUNTING THE BOILER
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.
Models 40/40P & 60/60P
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.
• Due care should be taken
when lifting the boilers, with
respect to their weights, see
Table 2 on Page 6. Also refer
to Safe Handling on Page 8.
1. 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.
2. Using the remaining coach
screws, secure the bottom of
the boiler to the wall through
the attached brackets.

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.
The temperature within the boiler room shall not exceed 25ºC within 100mm of the floor, 32ºC at mid height and 40ºC within 100mm
of the ceiling.
Models 80, 80P, 100, 120, 150 and multiple boiler
applications
Detail reference should be made to BS. 6644 for inputs
between 70kW and 1.8MW (net). In IE refer to the current
edition of 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
ventilation options refer to BS. 6644. In IE refer to the current
edition of I.S.820.

Note: Where a boiler installation is to operate in summer
months (e.g. DHW) additional ventilation requirements
are stated, if operating for more than 50% of time (refer
to BS6644).
Room Sealed Installations
A minimum of 2cm

free area per kW of net heat input at
both high and low level is required for boiler rooms. For
enclosures refer to BS6644.
