Clearances
(Figs. 12 &13)
1. A flat vertical area is required for the installation
of the boiler.
2. These dimensions include the necessary
clearances around the boiler for case removal,
spanner access and air movement. Additional
clearances may be required for the passage of
pipes around local obstructions such as joists
running parallel to the front face of the boiler.
3. For unventilated compartments see Section 7.5.
7.4
Location
NOTE:
Due to the nature of the boiler a plume of
water vapour will be discharged from the flue. This
should be taken into account when siting the flue
terminal.
1. The boiler may be fitted to any suitable wall with
the flue passing through an outside wall or roof and
discharging to atmosphere in a position permitting
satisfactory removal of combustion products and
providing an adequate air supply. The boiler should
be fitted within the building unless otherwise
protected by a suitable enclosure i.e. garage or
outhouse. (The boiler may be fitted inside a
cupboard - see Section 7.5).
2. If the boiler is sited in an unheated enclosure
then it is recommended to incorporate in the system
controls a suitable device for frost protection.
3. If the boiler is fitted in a room containing a bath or
shower reference must be made to the current
I.E.E. W
IRING
R
EGULATIONS
and
B
UILDING
R
EGULATIONS
. If the boiler is to be fitted into a
building of timber frame construction then reference
must be made to the Institute of Gas Engineers
document UP 7.
