2.1 Boiler Location
This boiler is not suitable for outdoor installation.
This boiler may be installed in any room, although particular
attention is drawn to the installation of a boiler in a room
containing a bath or shower where reference must be made to
the relevant requirements.
This boiler is suitable for installation in bathroom zones 2 and 3.
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.
The boiler must be mounted on a flat wall, which is sufficiently
robust to take its total weight, see Table 1. Section 1.
2.2 Clearances
The boiler should be positioned so that at least the minimum
operational and servicing clearances are provided, see diagram
2.1.
Additional clearances may be beneficial around the boiler for
installation and servicing.
For flue installations where external access is not practicable,
consideration should be given for the space required to insert
the flue internally, which may necessitate clearance larger than
those specified in diagram 2.1.
2.3 Timber Frame Buildings
If the boiler is to be installed in a timber frame building it should
be fitted in accordance with the Institute of Gas Engineers
document IGE/UP/7/1998 and BG Operational Procedures,
Part 19 Building and Kitchen Work, Section 7 - Timber Frame
Constructions. If in doubt seek advice from the local gas
undertaking or Glow-worm.
2.4 Room Ventilation
The boiler is room sealed, so when it is installed in a room or
space, a permanent air vent is not required.
2.5 Compartment Ventilation
Due to the high efficiency and hence low casing temperature of
this boiler, cupboard or compartment ventilation is not necessary.
Leave existing air vents.
