construction, use the cable fixing method.

Method 2 - Cable fixing, see diagram 3.6. To fix secure
the four eyelets in the fire opening. Attach the cables to
the upper cable tensioning brackets at the rear of the
appliance. Thread the cables down through the eyelets,
forward through the holes at the bottom rear of the
appliance and out through holes in the lower cable
tensioning brackets. As you offer the appliance to the
wall pull the slack cable tight. Thread the cables through
the cable clamps pull tight and secure with the cable
clamp locking screws. Apply extra tension if required
using the adjuster wing nuts. Loop the excess cable, do
not cut it off.

5 Instructions to User

Hand the Instructions for Use to the user and make sure
that they are understood.

Refer to the Instructions for Use on how to light the fire.
Advise the customer that they should read their Users

instructions before operating the fire and always follow
the advice in the Section headed “Cleaning your Fire”.

Advise that any smell which may be apparent on initial
lighting is quite normal and it will quickly disappear.

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 that to ensure the continued efficient and safe
operation of the fire it is recommended that it is checked
and serviced at regular intervals. The frequency of
servicing will depend upon the particular installation and
usage, but in general once a year should be enough.

Advise that the chimney must be checked at least once a
year and any debris found removed.

Draw attention, if applicable, to the current issue of the
Gas Safety (Installation and Use) Regulations, 35, which
imposes a duty of care on all persons who let out any
property containing a gas appliance.

It is the Law that any servicing must be carried out by a
competent person.

Reminder, leave these instructions with the user.

6.1 Notes

To ensure the continued efficient and safe operation of
the fire it is recommended that it is checked and serviced
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 any servicing is carried out by a
competent person.

Refer to Section 1.
Before starting make sure that the gas and electrical

supplies are turned off.
Make sure that the fire is cold before doing any servicing.
After servicing of parts always test for gas soundness

with a suitable leak detection fluid.
WARNING. Take care as the burner has a naked flame.
To test the gas control assembly apply leak detection

fluid to all joints, light the burner and check all joints for
leakage at all settings.

Carry out functional check of controls.
After removing or disconnecting any pipework always

make sure that it is refitted correctly and does not
interfere with the fitting of the fire.

Control of Substances Hazardous to Health

Information for the Installer and Service Engineer.

Under Section 6 of The Health and Safety at Work Act 1974, we are required to provide
information on substances hazardous to health.
The adhesives and sealants used in this appliance are cured and give no known hazard in this state.

FUELBEDS, ARTIFICIAL FUEL
This product uses fuel effect Pieces containing Refractory Ceramic Fibre (RCF), which are man­made vitreous silicate fibres. Excessive exposure to these materials may cause temporary irritation
to eyes, skin and respiratory tract, consequently, it makes sense to take care when handling these
articles to ensure that the release of dust is kept to a minimum.
To ensure that the release of fibres from these RCF articles is kept to a minimum, during installation
and servicing we recommend that you use a HEPA filtered vacuum to remove any dust and soot
accumulated in and around the fire before and after working on the fire. When replacing these
articles we recommend that the replaced items are not broken up, but are sealed within heavy duty
polythene bags, clearly labelled as RCF waste. This is not classified as “hazardous waste” and may
be disposed of at a tipping site licensed for the disposal of industrial waste. Protective clothing is
not required when handling these articles, but we recommend you follow the normal hygiene rules
of not smoking, eating or drinking in the work area and always wash your hands before eating or
drinking.

INSULATION PADS/CERAMIC FIBRE, GLASSYARN, MINERAL WOOL
These can cause irritation to skin, eyes and the respiratory tract.
If you have a history of skin complaint you may be susceptible to irritation. High dust levels are
usual only if the material is broken.
Normal handling should not cause discomfort, but follow normal good hygiene and wash your
hands before eating, drinking or going to the lavatory.
If you do suffer irritation to the eyes or severe irritation to the skin seek medical attention.

Because of our constant endeavour for improvement details may vary slightly from those in the instructions.
