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 over firing.
Connection to the Chimney
An existing fireplace opening can be bricked up or sealed with a register plate. A short length of flue
pipe of a minimum 125mm 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 125mm.
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.
Material Clearances
A MINIMUM clearance to combustible material MUST be at least 1500mm.
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.
Commissioning and Handover by Installer
After completion of the installation, allow a suitable period of time for any fire cement and mortar to
dry out. A small fire should be lit first and checked to ensure the smoke and fumes are taken from the
stove up the chimney and emitted safely to atmosphere. Do not run the stove at full output for at least 3
to 4 days.
Upon finishing the installation and commissioning, the installer must ensure that the operating
instructions and operating tools for the stove are left with the customer. They should also advise the
customer on the correct use of the appliance and warn them to use only the recommended fuels for the
stove. Warn the user on what to do should smoke or fumes be emitted from the stove and to use a
suitable fireguard in the presence of children, aged and/or infirm persons.
