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
).
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 (
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

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).
