6. Cleaning Ivory Painted Appliances
6.1 Allow appliance to cool thoroughly to avoid risk of
burns.
6.2 Ivory painted appliances require special attention when
cleaning. They have been coated with a high quality paint
that should give many years of service. However, this colour
will mark more easily and require cleaning more than other
models.
6.3 Take care when touching the appliance to avoid marking
the paint. Most marks can be removed using a mild soap
solution and a clean lint free cloth. The finish can also be
refreshed using aerosol touch up paint (product code 2055)
available from your Gazco retailer.
7. Arrangement of Fuel Bed
Advice on handling and disposal
of fire ceramics
The fuel effect and side panels in this appliance
are made from Refractory Ceramic Fibre (RCF),
a material which is commonly used for this
application.
Protective clothing is not required when
handling these articles, but we recommend you
follow normal hygiene rules of not smoking,
eating or drinking in the work area and always
wash your hands before eating or drinking.
To ensure that the release of RCF fibres are kept
to a minimum, during installation and servicing
a HEPA filtered vacuum is recommended to
remove any dust accumulated in and around the
appliance before and after working on it. When
servicing the appliance it is recommended that
the replaced items are not broken up, but are
sealed within heavy duty polythene bags and
labelled as RCF waste.
RCF waste is classed as stable, non-reactive
hazardous waste and may be disposed of at a
licensed landfill site.
Excessive exposure to these materials may
cause temporary irritation to eyes, skin and
respiratory tract; wash hands thoroughly after
handling the material.

6.3 The appliance is not suitable for installation against a
combustible wall. All combustible materials must be
removed from behind the appliance.
6.4 Ensure that all minimum clearances to combustible
materials are complied with as shown in Diagrams 4 & 5.
The specified clearances provide the minimum distance
to combustible materials. If the appliance is intended to
be installed into a non-combustible opening the clearance
to the sides and above the appliance can be reduced.
However, it is recommended that the specified clearances
are maintained irrespective of the materials used in the
construction of the opening to allow adequate air flow
and access to controls. The clearance at the rear of the
appliance must always be a minimum of 50mm.

Unpacking
1.6 Remove the appliance from its packaging, and check that it
is complete and undamaged.
2. Upgrading the Appliance
2.1 The appliance is fitted with a control valve that can easily be
upgraded to battery powered remote control.
There are two versions of this control which can be obtained
through your local Gazco retailer.
There is no requirement for this upgrade to be carried out by
an approved GasSafe engineer. However Gazco recommend
that this task is undertaken by a suitably competent person.
2.2 This upgrade can be fitted before or after installation but if
side clearances are limited then it will be easier to upgrade
the appliance before installation. Full instructions are
included with the kit.

on the inlet fitting and turn the gas supply on. Light the
appliance and check all gas joints for possible leaks. Turn
the appliance to maximum and check that the supply
pressure is as stated on the databadge. Turn the gas off
and replace the test point screw, turn the gas on and check
the test point for leaks.
5. Arrangement of Fuel Bed
Advice on handling and disposal
of fire ceramics
The fuel effect and side panels in this appliance
are made from Refractory Ceramic Fibre (RCF),
a material which is commonly used for this
application.
Protective clothing is not required when
handling these articles, but we recommend you
follow normal hygiene rules of not smoking,
eating or drinking in the work area and always
wash your hands before eating or drinking.
To ensure that the release of RCF fibres are kept
to a minimum, during installation and servicing
a HEPA filtered vacuum is recommended to
remove any dust accumulated in and around the
appliance before and after working on it. When
servicing the appliance it is recommended that
the replaced items are not broken up, but are
sealed within heavy duty polythene bags and
labelled as RCF waste.
RCF waste is classed as stable, non-reactive
hazardous waste and may be disposed of at a
licensed landfill site.
Excessive exposure to these materials may
cause temporary irritation to eyes, skin and
respiratory tract; wash hands thoroughly after
handling the material.

6. Log Layout
6.1 There are 4 logs, each with an identification letter, A, B, C
and D. Log C has an arrow on the underside to indicate
its orientation. The arrow points towards the rear of the
appliance.
6.2 Place the largest log A on the burner with the location legs
on the underside against the stops on the rear of the burner
skin, see Diagram 13.
13
6.3 Place the rear face of log B against the stops on the front of
the burner skin. The front of the log will rest on the firebox
behind the two slots, see Diagram 14.
14
6.4 Place log C with the arrow pointing towards the rear of the
appliance. The front of the log will rest in the hollow on the
left-hand side of log B. The rear of the log will locate in the
left-hand hollow on log A, see Diagram 15.
15
6.5 Log D is placed with the Y shaped branch towards the front
of the appliance. There is a cutout on the top right hand side
of the front log (B). Locate the right hand branch of log D in
this cut-out and rest the top of the log in the location of log
A, see Diagram 16.
16
NOTE: ENSURE THAT LOGS ARE POSITIONED AS
DETAILED ABOVE.
7. Replacing the Door
