1 General Notes and Information

This fire front may be fitted to a Glow-worm back boiler WITHOUT
a flue blockage safety device.  Please refer to the supplementary
instructions at the end of this booklet, especially “Lighting the
Boiler”.

This Glow-worm gas fire front is to be used with a specially
designed Glow-worm Back Boiler Unit only.

This fire front and back boiler are NOT suitable for fitting to a
precast flue.

The fire front is delivered packed in two cardboard cartons,
which together contain all the parts necessary for the installation
of the fire front.

If the back boiler and fire front are to be installed at the same time
please read both sets of installation instructions before starting.

Wherever possible, all materials, appliances and components
to be used shall comply with the requirements of applicable
British Standards.

Where no British Standards exist, materials and equipment
should be fit for their purpose and of suitable quality and
workmanship.

1.1 Important Notice

This fire front is for use only on G20 gas.

This fire front is fitted with a flue blockage safety device which
will shut down the fire if there is an unacceptable spillage of
products at the draught diverter.  If the fire front shuts down
frequently for no appreant reason the first things to be checked
are the chimney and the air inlets into the room.  An additional
cause could be that the filter, in the gas tap has become blocked.
Any problems found must be put right by a competent person,
before the fire front is used again.

Sheet Metal Parts

WARNING.  When installing or servicing this fire front care
should be taken when handling metal parts (components) to
