7.0 Site Requirements

7.1 Location
NOTE: Due to the high efficiency 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 7.2).
2. If the boiler is sited in an unheated enclosure then it is
recommended to incorporate an appropriate device for
frost protection in the system controls.
3. If the boiler is fitted in a room containing a bath or
shower it MUST NOT BE fitted in zone 0, 1 or 2, ONLY
within the shaded area (Figs. A & B shows zone
dimensions for a bathtub. For other examples refer to
the Current I.E.E. Wiring Regulations) reference must be
made to the relevant requirements.
In GB this is the current I.E.E. Wiring Regulations and
Building Regulations.
In IE reference should be made to the current edition of
I.S. 813 "Domestic Gas Installations" and the current
ETCI rules.
4. 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).
7.2 Ventilation of Compartments
1. Where the boiler is installed in a cupboard or
compartment, no air vents are required for cooling
purposes providing that the minimum dimensions below
are maintained.
Sides 15mm
Top 200mm
Bottom 50mm
Front 30mm
2. If the boiler is installed in a smaller cupboard or
compartment it must be ventilated according to
BS 5440 Part 2 and the minimum clearances given in
section 4.0 "Technical Data" maintained.
3. Any compartment should be large enough to house
the boiler only.
NOTE: The ventilation label on the front of the outer
case MUST NOT BE REMOVED when the appliance is
installed in a compartment or cupboard.
