Installation Instructions
A qualified person should complete all building work; a qualified and
competent person to all relevant national legislative controls must carry out
the installation of gas burners, mechanical extraction, flue systems and
remote control units.
Final responsibility for the complete installation is with the Gas Safe Engineer
who connects this appliance to the gas supply.
Building work
Building work should only commence after a thorough survey of the intended
location of installation has been completed and it has been established that
the unit can be installed and operated without risk to the owner or tenants of
the property or their neighbours.
Where existing chimney systems are to be used in conjunction with the
appliance, they should have been swept and undergone thorough examination
to ensure that they are in a sound and safe condition, as well as providing an
adequate draw when the gas fire unit is in operation. [See Technical Section]
A simple smoke test will reveal whether or not the chimney is working
correctly.
Installation Procedure
It is important that the gas supply is disconnected before any existing
surround and hearth is removed.
The original fire opening must be closed, using bricks / blocks. In fill any void
below the fire to ensure a solid base is available to mount the enclosure. Allow
15mm clearance in the height of the fire opening for adjustments.
In some installations it is necessary to install a small lintel unit above the
opening. If so, an allowance must be made to accommodate the lintel. NOTE -
The FIREBREAK does not have its own support lintel.
The FIREBREAK enclosure should be located centrally to the existing flue /
chimney at your desired height.
Ensure the gas supply is to the required standard [pipe work size is critical on
this appliance] and electrical connections are in place (READ EARLIER
SECTIONS). Any unused access holes must be sealed with suitable metal
tape. This ensures that air cannot be drawn into the chimney from the lower
half of the appliance. If not done there will be adverse air travel and flame
reversal will occur when the appliance is lit.
