5. BUILDERS OPENING
Many fireplace openings have a supporting lintel. Remove
the covering plaster to identify it's position before starting
any constructive work. Do not remove constructional lintels
without making provision to support the remaining structure
of the building. The appliance must not form any part of the
supporting structure.
5.1 The chimney/flue must have a sealed connection to the
appliance flue spigot.
5.2 The structure of the builders opening will reach high
temperatures. Use insulating blockwork to reduce the heat
transfer to the external walls, in particular the area of the
chimney breast above the opening.
5.3 Take care when finishing the chimney breast and
surrounding area. The conducted and convected heat
emitted by the appliance could be high enough to crack
normal plaster. Use a high temperature plaster, or face
the area with a suitable high temperature plasterboard.
New plaster should be fully dried before the appliance is
used, or cracking could occur.

If you are in any doubt about your ability to produce a
safe opening contact your Stovax dealer for professional
advice.*
6. FIRE SURROUND CLEARANCES

6.1 We recommend you obtain expert advice before
proceeding with work of this nature.
6.2 Some finishes may discolour with heat and some lower
quality products may distort, or crack, when in use.
If stone / granite / marble or any other natural material
is used to construct the fire surround, or any part of it,
provision should be made for expansion and movement
of the parts due to heating and cooling.
If you are in any doubt about the installation
requirements, or suitablity of fire surrounds contact your
Stovax dealer.
6.3 All fire surrounds should be suitable for use with solid fuel
heating products.
