FireFlexmaster
Installation
For Gas, Oil, Wood and Solid Fuel
PREPARATION
Good working practices and statutory health and safety considerations should be followed. The
installation of
FireFlexmaster
chimney lining is a two person job.
Safe working platforms or other means of access should be arranged to avoid accidents. Wear
protective gloves, goggles and dust-masks, particularly when handling dusty or sooty materials.
There is a danger of cuts and abrasions from the liner and metal fittings.
FireFlexmaster
can be used with UK fuels
such as standard fuel oil, gas, ‘clean burn’ coal,
as
well as wood and wood products, providing it is suitably cured. The product is not suitable for
biomass boilers or stoves.
SIZE OF LINING
The following is a general guide for flue sizing but referral should be made to Building
Regulations ADJ Clause 2.4 and Table 2.
Solid-fuel stoves, room heaters, boilers and cookers:
Minimum 6” (150mm) diameter, 7” – 8” (175mm – 200mm) for larger or multi-fuel appliances.
Other appliances:
Consult the appliance manufacturer. Unless the appliance manufacturer recommends
otherwise, the diameter of the liner should not be smaller than the appliance outlet.
PREPARING THE CHIMNEY
Check that the appliance and chimney arrangements are satisfactory and that the walls of the
chimney are at least 100mm thick solid masonry; ensure that the chimney is structurally sound.
Clean the chimney using a brush and rods, your chimney sweep should be able to determine
the length of the chimney, you will need to know this to order the correct length of
FireFlexmaster
flue liner
.
FireFlexmaster
chimney liner is supplied in one continuous length.
It is better to over order as
the
FireFlexmaster
chimney liner
cannot be joined together.
Remove any terminals, chimney
pots, cappings, damper plates or any other obstructions, which might effect installation of the
liner. If there are severe bends or obstructions in the length of the flue, the chimney wall will
require opening to ensure proper access and installation. The openings must be repaired using
the appropriate materials and workmanship after installation.
There are two methods of installation at the top of the stack that we suggest;
1)
Without chimney pot
or
2)
With chimney pot
