1.5 Site Requirements
Refer to diagram 1.1 for dimensions appropriate to the back
boiler.
For all types of installation a standard builder’s front opening is
required, see diagram 1.2.
IMPORTANT NOTES :
The depth of the fire opening MUST conform to the dimensions
given in diagram 1.2.
Any larger front opening will need to be reduced, with non-
combustible material to conform to this requirement.
It is important that the opening is cleared of debris and mortar
etc.
The void behind the the front opening should be sufficient to
allow for the water connections fittings.
It is recommended that the access hole for pipework into the
fireplace or builders opening is either at the left hand or right
hand side of the chimney breast. if access is required at both
sides then it may be necessary to prepare some of the
connections before fitting the back boiler into the builders
opening.
The prepared base for the back boiler must be level.
Refer to diagram 1.3 for dimensions of the fire fixing wall face
which MUST be true.
