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.
EVOMAX 30/30P, 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.

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.
• 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.
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.

Detail reference should be made to BS. 6644 and IGEM/UP/10
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 and IGEM/UP/10. 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) and
IGEM/UP/10.
Room Sealed Installations
A minimum of 2cm
2
free area per kW of net heat input at both
high and low level is required for boiler rooms. For enclosures
refer to BS6644 and IGEM/UP/10.
