Location
1. The boiler must be positioned on a flat and level
floor or base which must be capable of supporting
the full operational weight of the boiler. The flue
must pass through an outside roof or wall and
discharge to atmosphere in a position permitting
satisfactory removal of combustion products.
2. The boiler should be fitted within the building
unless otherwise protected by a suitable enclosure
i.e. garage or outhouse. (The 120 and 150 boilers
may be fitted inside a cupboard - see Section 6.7).
3. If the boiler or any part of the system is located
in an area that may be subjected to low ambient
temperatures, it is recommended that a suitable
frost protection device is incorporated into the
control system.
4. If the boiler is fitted in a room containing a bath
or shower reference must be made to the current
I.E.E. Wiring Regulations and Building
Regulations. If the boiler is to be fitted into a
building of timber frame construction then
reference must be made to the current edition of
Institute of Gas Engineers Publication IGE/UP/7
(Gas Installations in Timber Framed Housing).
6.5
Gas Supply
1. The gas installation should be in accordance
with BS6891.
2. The connection to the appliance is a 22mm
copper tail. This is connected to the gas service
cock (Fig. 9).
3. Ensure that the pipework from the meter to the
appliance is of adequate size. Do not use pipes of
a smaller diameter than the boiler gas connection
(22mm).
6.6
Electrical Supply
1. External wiring must be correctly earthed,
polarised and in accordance with current I.E.E.
Wiring Regulations.
2. The mains supply is 230V ~ 50Hz fused at 3A.
NOTE:
The method of connection to the electricity
supply must facilitate complete electrical isolation
of the appliance.
Connection may be via a fused double-pole
isolator with a contact separation of at least 3mm
in all poles and servicing the boiler and system
controls only.
