PRE-INSTALLATION
3.7 BOILER LOCATION & CLEARANCES
This boiler is only suitable for installing internally within a property at a
suitable location onto a fixed, rigid non-combustible surface at least the
same size as the boiler and capable of supporting the boiler weight.
NOTICE:
No surface protection is required against heat transfer
from the boiler.
COMPARTMENTS:
Follow the requirements of BS6798 and BS5440 Part 2 and note:
• Minimum clearances must be maintained
• An access door is required to install, service and maintain the boiler
and any ancillary equipment.
• If an airing cupboard is adapted to house a boiler, then the airing
spaces must be separated from the boiler compartment by a
noncombustible partition. The partition may be perforated, if
required, by holes not exceeding 13 mm in diameter.
• If the appliance is fitted into a cupboard or a compartment is built
around the appliance after installation, then the compartment must
be built or lined by a non-combustible material.
BOILER CLEARANCES:
The drawing below Fig. 15 shows the minimum space required to install
and service the boiler.
VENTILATION
This is a room sealed appliance and does not require any air for
combustion from inside the property.
The requirements of BS 6798 and BS 5440 regarding ventilation do not
apply, with the Greenstar CDi System boiler. There is no need for
ventilation openings to be provided in the compartment because of the
low heat loss from the appliance casing, if the clearances shown are
maintained.
Do not operate the appliance if the flue terminal fitted on the outside wall
or roof is obstructed or damaged.
