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 in the system controls a
suitable device for frost protection.

it can only be fitted in zone 3, (Figs. A & B shows zone
dimensions for a bathtub. For other examples refer to
Section 601 of 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
