Material Clearance Dimensions; Distances From Combustible Materials; Distances From Non Combustible Materials; Hearths - Fireline PUREVISION Installation And Operating Instructions Manual

Ideally, the old fireplace should be filled in so that there is a smooth streamlined entry into the
flue way. It is essential that all connections between the stove and chimney-flue are sealed and
made airtight with sealing rope, clamping rings and/or fire cement or heat resisting cement
where required.
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.

In addition it is strongly recommended that any furniture or other combustible materials are
kept at least 900mm clear from the front of the stove.
COMBUSTIBLE SHELVES AND BEAMS
Due to the fact that combustible shelves, timber fireplaces and beams have potentially
thousands of possible configurations in conjunction with stoves outset or inserted partially or
fully into chambers, it is not possible to give firm guidance on dimensions to these features. As a
guideline, materials that are in 'line of sight' to the stove are more likely to overheat due to
direct radiation from the stove body than materials that are not in 'line of sight' (e.g. with stove
fully inside a chamber). Materials above the stove are far more likely to overheat than materials
alongside or below. A guideline limiting temperature for solid timber (not surface finishes) is
approximately 80-85 degrees C with a normal ambient room temperature. Temperatures of
combustible materials can be substantially lowered with a simple heat shield constructed of a
non-combustible material and small air gap (6-12mm for example) between the shield and
combustible material.
5.6.2. Distances from NON-combustible materials:
The stove can be recessed in a suitable sized non-combustible fireplace but a permanent free
air gap of at least 50mm must be left around the sides and top and at least 50mm at the back of
the stove to obtain reasonable heat output and for access to the stove for removal and
maintenance. A clearance of 150mm will give a better heat output
In accordance with Building regulations all non-combustible walls closer than 400mm to the
stove should be at least 75mm thick. For practical reasons the back wall of the fireplace recess
and the hearth should be made of non-combustible material.

5.7. Hearths:

Purevision freestanding stoves do not require a constructional hearth beneath them as they do
not cause the floor temperature to exceed 100 degrees C. Hearths must be generally level. In all
instances a non-combustible superimposed hearth extending fully underneath the stove and
forming an apron of at least 225mm at the front of the stove and 150mm on either side must be
