The installation of any electrical services during the installation of this boiler and the associated
heating system must be carried out by a registered competent electrician in accordance with the
requirements of the latest issue of BS7671.

D raught
A flue draught of minimum 1.2mm to a maximum 2.5mm water gauge is required for
satisfactory appliance performance. The flue draught should be checked under fire at
high output and, if it exceeds the recommended maximum, a draught stabiliser must be fitted so
that the rate of burning can be controlled and to prevent overfiring.

An existing fireplace opening can be bricked up or sealed with a register plate. A short length of
flue pipe of a minimum 150mm internal diameter may then be used to connect the stove to the
chimney. This flue pipe should conform to Building Regulations. Ensure that the pipe end is no
closer than 76mm to the side or rear chimney walls.
Ideally, the old fireplace should be filled in so that there is a smooth streamlined entry into the
flueway. The length of any horizontal run of flue pipe must not exceed 150mm.
It is essential that all connections between the stove and chimney-flue are sealed and made
airtight. This appliance is not suitable for installation in a shared flue system.
Both the chimney and flue pipe must be accessible for cleaning and if ANY parts of the chimney
cannot be reached through the stove (with baffle removed), a soot door must be fitted in a
suitable position to enable this to be done.

The stove can be recessed in a suitable sized fireplace but a permanent free air gap of at least
150mm must be left around the sides and top and at least 50mm at the back of the stove to obtain
maximum heat output and for access to the rear of the stove.
All non-combustible walls closer than 400mm to the stove should be at least 75mm thick. In all
instances the back wall of the fireplace recess and the hearth should be made of non-combustible
material. Allow an apron of at least 300mm at the front of the stove and 150mm on either side.
The hearth on which the stove is to be placed should not be less than 125mm thick and should be
in accordance with the current building regulations.
Care should be taken to level the stove using the adjusting screws in the feet.
The appliance shall be installed on a floor with adequate load-bearing capacity. If the existing
construction does not meet this prerequisite, suitable measures (e.g. load disturbing plate) should
be taken to achieve it.
