Installation instructions
1 INTRODUCTION
1.1 GENERAL
The gas fire must be positioned and connected as an “open” appliance by a “Gas Safe
Register” registered gas installation engineer in accordance with the following installation
instructions, nationally and locally applicable regulations (see “Technical Details /
Regulations” at the rear of this manual). If you have any queries regarding the
installation, please consult your local gas company.
This manual contains directions for both positioning and for connecting
the appliance
.
It also contains indications for the annual maintenance, technical data for the appliance,
parts information and directions in the event of problems.
Study the Installation instructions carefully before using the appliance. We recommend
you keep this manual in a safe place for reference purposes.
Read the “Instructions for use & maintenance manual” before operating the appliance
Important: Before beginning the installation, check that the details on the
rating plate correspond to the gas type and pressure to which
the appliance will be connected.
If an existing chimney is to be used, please consult your installer first. If the chimney
was previously used for a wood or coal fire, then it should be cleaned by an expert. A
chimney draw of approximately 5 Pa (=0,05 mbar) is sufficient for full load of the
appliance. If the chimney draw is more than 20 Pa (=0,2 mbar), then it is recommended
to reduce it.
The appliance is factory set to the correct nominal heat input. The pilot light is set to the
correct level of consumption.
The gas fire can be installed as an insert into an existing open fire place or as a
built-in appliance in a new fire place.
1.2 SAFETY
• Do not place embers, wood logs or shingles against the pilot light burner. Make sure
that the pilot flame can burn at all times freely over the main burner. Only in this way
is proper ignition of the main burner ensured.
Ignoring these directions could lead to a dangerous situation.
• Do not place flammable objects within 100 cm of the appliance. Pay special attention
to furnishings and ornaments around the fire.
• When igniting the pilot light and burner, always keep a minimum distance of 100 cm
from the front of the appliance.

Installation instructions
•If the pilot !ame goes out for any reason, wait for 5 minutes before attempting to
re-light it.
• It is essential that the appliance, the complete !ue system and the room ventilation
openings are cleaned and inspected annually by a recognised "tter/gas specialist.
The safe operation of the appliance will thus remain guaranteed.
See Chapter 3: Annual maintenance.
• The gas "re must never be used with the door open or the door glass removed.
• Never place !ammable material on the ceramic log set.
• The "lling of the main burner with embers, wood logs or pebbles may not under any
circumstances be changed or added to.
• Do not place easily-!ammable materials, such as nylon clothing or !ammable liquids,
in the vicinity of the gas "re.
• Ensure at all times that children and other people who are not aware of the operation
of the gas appliance are only in the vicinity of the appliance exclusively under
supervision.
• Use a "reguard to protect the people and children mentioned above against possible
burns.
1.3 BUILT-IN PROTECTION OF THE APPLIANCE
The appliance is fully protected by means of a thermo-electric pilot light shut off in the
event of a gas escape from the main burner.
Flue gas exhaust protection:
Also the appliance is "tted with an atmosphere protection facility. This is an “oxy-stop”
pilot !ame that turns off the burner if the !ue gas is insuf"ciently exhausted
When the !ame is blue and hazy (when the appliance is burning for some time), this
means that combustion is not correct, and that the “oxy-stop” will be activated within a
certain period.
If the “oxy-stop” pilot !ame is activated then check that the air supply and the !ue
exhaust are open. Following isolation of the cause, the appliance can be put back into
operation.
Always contact your installer in the event of continual problems.
It is not permitted to disable or modify the protection.

N.B. If any part is missing, please contact your dealer.
1.4 INCLUDED
In the event that the “oxy-stop” pilot !ame is to be replaced, then only the original model
should be applied.
This atmosphere protection; the “oxy-stop” pilot light, is not a substitute for an
independent-mounted carbon monoxide detector.
