Installation Continued
The stove can be recessed in a suitable sized fireplace but a permanent free air
gap of at least 100mm must be left around the sides and top to obtain maximum
heat output and for access to the rear of the stove. There should not be any
combustible material within a distance of 450mm from any surface of the stove.
Furniture and general soft furnishings should not be within 900mm of any stove
surfaces including the stove pipe. In all instances the stove In all instances the stove
should be positioned on a non-combustible hearth. 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 if the floor is made of
combustible material, and care should be taken to level the stove and secure the
hearth. If existing floors do not have adequate load bearing capacity then suitable
modifications i.e. load bearing plates must be adopted.
When the stove is desired position mark hearth through holes in feet, remove stove
drill and plug hearth for securing stove and levelling.
Upon completion of installation, the appliance should be checked under fire for
soundness of joints and seals, and also that all smoke and fumes are taken from the
appliance, up the chimney and emitted safely.
Care should be taken that all flues, hearths, and combustion air supplies are in
accordance with the current Building Regulations, Local Authority Bye-Laws, British
Standards and Codes of Practice. The Firefox 5 CB has no ventilation requirement
but a fixed vent is advisable as this will enhance the pull of the chimney and reduce
unwanted draughts. Care should be taken that these opening cannot become
obstructed. Considerations and provisions must be made for any other appliances
requiring ventilation. An extractor fan must not be used in the same location as the
appliance. This appliance is not to be used with a shared chimney.
Operating Instructions
The appliance uses the down burn principle unlike conventional stoves where the
flame path rises up to the baffle plate in the top of the stove, circulates around the
baffle then out through the flue outlet. The down burn stove has a throat at the
bottom rear of the fire box. Behind the back brick is a combustion chamber that
has its own air supply, the flame passes up into the fire box then down into the
throat, it then enters the combustion chamber where it is injected with pre-heated
air. This causes a rise in temperature burning off smoke particles, creating cleaner
emissions. After entering the combustion chamber the hot gasses circulate around
the inner baffle and out round the flue outlet.
The secondary and tertiary air supplies create the clean burn function; these air
supplies are not adjustable. The primary air supply controls the burn rate. There is a
fixed primary air bleed on the door located above the primary air slide.
