PRESSURE RELIEF PIPE WORK
•
The pressure relief drain pipe (1) from the boiler should be at least
15mm diameter copper pipe and run downwards, away from any
electrical equipment or other hazard, preferably to an external drain
or soak away.
•
Pipe (1) should be finished with a partial bend, near the outlet to face
the external wall (as shown) to help prevent freezing.

BOILER LOCATION & CLEARANCES
This boiler is only suitable for installing internally within a property at a
suitable location onto a fixed, rigid surface at least the same size as the
boiler and capable of supporting the boiler weight.
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 non-
combustible 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 diagram opposite 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 Combi 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.
NOTICE:
Unheated internal areas.
B
Internal pipe runs in unheated areas such as lofts,
basements and garages should be treated as external
runs.
NOTICE:
B
The pressure relief valve is a safety device for the
boiler and if activated may discharge boiling water or
steam through the relief valve drain pipe.
B
Care should be taken when siting the outlet pipe so
that it does not cause an obstruction or discharge
above a window, entrance or other public access
where it could cause a hazard.
