4) Locate the boiler in the fireplace opening ensuring that
the 'V' in the front plate is about the centreline of the
opening and horizontally aligned with the front
opening.
5) Offer the spigot hood up to the flue hood to ensure it
will fit inside the front opening.
6) Mark the position of the fixing holes, move the boiler
clear of the marked points then drill and plug the
holes.
7) Position the boiler back over the holes and secure to
the floor with the 2 No. 8 x 1" Pozi Woodscrews
provided.

Remember ! The burner/gas valve assembly will be fitted

off tap should be installed close to the boiler if it is
in a low point of the system.
Note: On combined Gravity DHW Pumped Heating
Systems the injector tee must be fitted directly to
the boiler. The tee on the combined flows is to be
fitted as close to the boiler as possible.
