a)
Boiler Location
The boiler may be installed in any room to any suitable wall which is capable of carrying its weight with the flue passing through an
outside wall or roof and discharging to atmosphere allowing satisfactory removal of combustion products and providing adequate air
supply. However particular attention is drawn to: -
•
The requirements of the current issue of BS7671 with respect to the installation of a boiler in a room containing a bath or a shower.
Any electrical switch or boiler control using mains electricity supply should be so sited that a person using the bath or a shower cannot
touch it. The electrical provisions of the Building Standards (Scotland) Regulations are applicable to such installations in Scotland.
•
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 ' gas Installation in timber Frame Housing' . If in doubt, ask local gas utility company or Gledhill Water Storage Ltd.
This boiler is not suitable for fitting outdoors. It should be fitted within the building unless otherwise protected by a suitable enclosure
i.e. garage or out house. If the boiler is sited in an unheated space then it is recommended that the boiler 'on-off' switch is always left in
the 'ON' position to give frost protection. It may also be necessary to install additional frost protection device to protect other parts of
the system.
The boiler may be fitted inside a cupboard or a compartment without any air vents. The appliance will run sufficiently cold without ventilation.
The installation in cupboards must comply with BS 5440: Part which refers to room sealed appliances installed in compartments.
The boiler must be mounted on a flat vertical wall, which is sufficiently robust to take its total weight of 50 kg. The overall dimensions are
shown in fig .6 and the clearances required are shown in figure 4.8.
b)
clearances
The boiler should be positioned and installed so that at least the minimum clearances shown in figure 4.8, are provided for servicing
and correct operation. Additional clearances will be useful around the boiler during installation and servicing.
For flue installations where external access is not practical, consideration will need to be given to the space required to install the flue
internally, which may require clearances larger than those specified in figure 4.8.
c)
ventilation requirements
The boiler is room sealed, so
when it is installed in a room or
space, a permanent air vent is not
required.
If the boiler is installed in a
compartment, a permanent air
vent is not required. However there
is no need for existing air vents to
be removed.
