Installation Instructions
SECTION EIGHT Siting the Appliance

CLASS ONE
That is a conventional brick or stone chimney as used for a solid fuel appliance with an effective cross-
sectional dimension of 225 x 225 mm (9” x 9”) or a lined flue with a minimum diameter of 125mm (5”). The
chimney must have a minimum effective height of at least 3 metres. Any permanent flue restriction or variable
dampers are to be removed or locked fully open. The chimney should be swept prior to installation if it has
previously been used with solid fuel. This is not necessary if the flue has previously been used with a gas
appliance or if it is a new installation.
Note: A brick or stone chimney with a 125 mm (5 ins) minimum diameter flue liner conforming to BS 715 may
be used. Provided a suitable sealing plate is fitted to the base of the liner and the appliance does not restrict
the opening into the liner. Ensure a smooth lead into the flue way and no combustible materials are used. A
void of 50mm must be maintained from the top of the firebox to gather into flue.
PREPARING THE OPENING FOR STANDARD INSTALLATION
The front face and the base of the fire opening must be flat to ensure that a good seal is formed between the
rear and base of the appliance and the chimney to avoid any reduction of natural draught.
773-825mm
943-960mm
Floor
This area behind the trim/fascia
must be clear of combustible
material and be flat for the seal.
