1 General Notes and Information
1.1 Important Notice
The fire is fitted with a safety device which will shut it
down if there is a lack of oxygen. If the fire shuts down
frequently for no apparent reason the first things to be
checked are the chimney and 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 is used
again.
This fire front is for use only on G20 gas.
Sheet Metal Parts
WARNING. When installing or servicing this fire front
care should be taken when handling sheet metal parts, to
avoid any possibility of personal injury.

Hand the Instructions for Use to the user and instruct in
the safe and economical use of the fire and back boiler,
including lighting the fire with a spill, see below.
Draw attention, if applicable, to the current issue of the
Gas Safety (Installation and Use) Regulations, Section
35, which imposes a duty of care on all persons who let
out any property containing a gas appliance.
Advise that any smell which may be apparent on first
lighting is quite normal and it will quickly disappear.
Advise that the trims (not the decorative motif) are solid
brass and they only may be cleaned with a proprietary
metal cleaner and polish, such as “Duraglit”.
Important. Advise that soft wall coverings, for example,
blown vinyl wallpaper, are easily affected by heat, they
may, therefore, scorch or become discoloured when
close to a heating appliance. This should be borne in
mind when having a heating appliance installed and
when redecorating.

11 Supplementary Instructions
These fire fronts are fitted with combustion products
discharge safety devices.
As these fire fronts may be fitted to a Glow-worm 45,
56, 45R or 56R back boiler units WITHOUT a
combustion products discharge safety device, the
following instructions must be read and followed in
place of those in the main Installation and Servicing
Instructions.
To check if a combustion products discharge safety
device is fitted, refer to inset in diagram 11.1, if one is
fitted this supplement MUST be ignored.
11.1 General
To fit the fire front to one of the above EXISTING
GLOW-WORM BACK BOILER UNITS follow the
instructions below.
11.2 Installation
1. Do not fit the back boiler sensing tube as required in
the main installation and servicing instructions.
2. Fit the electrical connection supplied with the fire
front to the back boiler unit control box, see diagram
11.2 to identify if a four or six way terminal block is
fitted. Continue to fit the fire front as the relevant part of
the main installation and servicing instructions.
3. Any references in the installation and servicing
instructions to the back boiler unit combustion products
discharge safety device must be ignored.
Push in and slightly turn gas control knob “A” clockwise
until “ ” is against its setting point, that is, set to “Off”.
Push in slightly and turn gas control knob “A”
anticlockwise until “ ” is against its setting point, then
push fully in and hold in.
At the same time press and release piezo button “D”
until pilot burner “E” lights. Look at flame through
viewing window “F”.
At initial lighting of the boiler air may be present and
several attempts may be needed to light the pilot.
Keep the control knob “A” pushed in whilst operating
the ignition button.
When the pilot is alight and stable, keep knob “A” fully
pushed in for about 15 seconds then release. Check that
the pilot is still alight, look through window “F”.
If the pilot burner fails to stay alight turn gas control
knob “A” “Off”, that is, fully clockwise. Wait three
minutes. Repeat the lighting operation, only now keep
the control knob “A” pushed in for a little longer that
before after the pilot has lit.
NOTE. Always wait three minutes before attempting to
relight the pilot after it has gone out for any reason.
Push control knob “A” in slightly and turn anticlockwise
until “ ” is against the setting point.
Note. If gas control knob “A” is turned to until “ ” is
against the setting point, a safety lock prevents it being
turned on again. No attempt should be made to turn the
valve on again until at least three minutes have elapsed.
