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.

6.1 Lighting and Testing
Make sure that the electrical supply to the back boiler is
isolated.
The fire front is fitted with a Combustion Products
Discharge 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.
The combustion products discharge safety device
MUST NOT be adjusted or disconnected.
If replacing use only the correct and approved parts.
Make sure that the flat on the drive rod faces the wall
before fitting the control knob, see diagram 6.1.

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.
Advise the user, to ensure the continued efficient and
safe operation of the appliance it is recommended that it
is checked and serviced as necessary at regular intervals.
The frequency of servicing will depend upon the
particular installation and usage, but in general once a
year should be enough.
It is the law that servicing is carried out by a competent
person.
Advise that the under fuel bed lighting can be used at
any time.
Demonstrate lighting the fire front with a spill or long
match, see diagram 7.1.
Remove the brass trim and front hearth casting.
Hold a lighted spill or long match and insert it into the
hole in the front plate, position the spill so that the flame
is over the burner.
Keep the spill in position, push in and turn the gas tap
knob to position 1, keep knob pushed in for about 10
seconds and the burner will light.
Once lit operate the gas tap normally.
Advise that this is a temporary measure, to be used only
if the ignition system should fail.
