1. General Notes
This Mendip gas appliance is a High Efficiency, Balanced Flue Live Fuel Effect appliance. It provides radiant and
convected heat using the latest burner technology. As well as having a variable heat output, these fires also
utilise a special control system that allows the appliance to use three burners for high output or a single burner
for lower outputs.
The Front Burner will be designated as the "Main" Burner, the second, rear burner, will be designated as the
"Effect" Burners. The Effect burner can be switched ON or Off whilst the appliance is alight.
Before Installation, check that the local distribution conditions, nature of the gas and pressure, and adjustment
of the appliance are compatible.
This appliance is intended for use on a gas installation with a governed meter.
This Gas Installation may only be installed by a registered professional competent person (Gas Safe installer
in the UK). The installation must adhere to the requirements of the local and national Building regulations and
national standards. The installation manual must also be followed.
Ensure that the Flue Terminal is not in any way obstructed and is clear of vegetation, i.e. trees, shrubs etc. and
that no objects are leant against the terminal or guard.
Always clean the Window Panel before the fire is ignited. Any finger prints must be removed, as these will be
burnt into the glass and will be un-removable.
Do not operate this appliance if the glass panel has been broken (or cracked), removed or is open.
The appliance is designed to fit numerous installation situations as listed in these installation instructions.
However only flue approved by Mendip for this appliance may be used.
This appliance is a balanced flue product and is room sealed and as such requires no additional ventilation for
operation. However an adequate supply of fresh air to maintain temperatures and a comfortable environment is
recommended.
This appliance is designed as a heating appliance, and as such will get very hot in operation; all surfaces (except
the controls and access door) are considered to be working surfaces and as such should not be touched. The
front windows and surrounds are not considered to be fully secure guards against accidental contact. It is
recommended that an approved fire screen be used if children, the elderly or persons with limited mobility are
to be present in the same area.
Do not place curtains, laundry, furniture etc. within a safe distance of 300mm of this appliance.
Do not attempt to burn rubbish on this appliance.

2.1 Emergency Gas Isolation
In the event of a gas leak or if gas is smelt, the appliance must be isolated. This is done by turning OFF the gas
at the Isolation Tap. This Isolation Tap is located in the foot of the appliance.
2.2 First Time of Operation
Before igniting the appliance, ensure that all packaging, safety stickers and any protective wrapping have been
removed, and that the glass has been cleaned, including all fingerprints from the glass.
Ensure that the room is adequately ventilated the first time that the appliance is ignited; we would recommend
opening windows if possible. Run the appliance at full setting for a few hours so that the paint gets an
opportunity to fully cure. During this period it is possible for some fumes and vapours to be given off. We would
recommend keeping children and pets out of the area at this time.

2.3 Control Overview
2.3.1 Basic Manual Control
1. Igniting the Pilot Light
1. From the OFF position, depress the control knob for five seconds (only pilot gas flows).
2. Turn the control knob anti-clockwise through the PILOT position and continue turning until the igniter
“clicks”, if the Pilot flame lights, hold for ten seconds (only pilot gas flows). If the Pilot has not Ignited,
return the control knob to the OFF position and repeat.
3. Upon releasing the control knob the pilot flame should remain alight, if not return the control knob to the
OFF position and repeat.
2. Igniting the Main Burner
The appliance should always be run on FULL for the first 30 seconds.
From the IGNITION position, turn the control knob fully anti-clockwise, this is the FULL position, gas should now be
flowing to the main burner and the burner should light on full.
3. Adjusting the Flame Height (heat setting)
From the FULL position, turn the control clock-wise, until the control knob reaches a stop, this is the LOW setting.
Any position between HIGH and LOW can be selected as an intermediate setting.

The control valve is located behind the control hatch in the Base of the appliance.
2.5 Cleaning and Maintenance
This appliance should be inspected and serviced once a year by a qualified, competent and registered person.
The inspection and maintenance must at least ensure that the appliance is working correctly and safely. It is
advisable to clean the appliance of any dust and debris before regularly during the heating season and especially
if the appliance has not been used for some time. This can be done with a soft brush and a vacuum cleaner or a
damp cloth and if required a non-abrasive cleaning agent. Do not use corrosive or abrasive substances to clean
the appliance.

3. Installation instructions.
Before commencing Installation, confirm that the details on the appliance data plate correspond to the local
distribution conditions, gas type and pressure to which the appliance is to be installed.
Ensure that gas supply and supply pipe is capable of delivering the required volume and pressure of gas and is in
accordance with the rules in force.
3.1 Gas Connection
This appliance has a gas inlet connection of Ø 8mm.
3.2 Ventilation
This appliance is a Balanced Flue room sealed appliance, and as such needs no additional ventilation. However
an adequate supply of fresh air to maintain temperatures and a comfortable environment is recommended.
This appliance may be installed in a completely sealed or mechanically ventilated house.
3.3 Appliance Fireplace Installation
Determine the position required for the appliance.
Create a gas connection for the appliance in approximately the correct location for the gas controls.
The gas controls are connected to the Burner of the appliance.
For clearance details see section 3.3.1. below.
The clearance distance of the Flue from combustibles must not be less than 75mm. This dimension can be
reduced to 25mm as the distance from the underside and the sides of Horizontal Flue runs.
The stove must stand on a fireproof hearth, which must be of a non-combustible material with a minimum
thickness of 12mm and extend 100mm in front of the stove.
The hearth must not be capable of inadvertent covering by a rug or carpet. This may be achieved by either the
hearth being 50mm above the level of the floor, or a fender or kerb around the hearth to a height of 50mm.
3.3.1 Clearance requirements
The appliance must not be fitted against a rear wall constructed from a combustible material; a gap of 300mm
should be given around the stove before combustible materials may be used in the wall construction.
If the appliance has to be located in an opening, the minimum clearance from non-combustible materials is:
To Rear : 50mm
To Right : 50mm
To Left : 50mm
The stove must be located at least 280mm from any combustible materials.
A combustible shelf may be fitted over the appliance, if in the case of a 150mm or less deep shelf, there is at
least 280mm clearance above the top of the stove. The shelf depth may increase at the same rate as the
increase in clearance; i.e. a shelf depth of 200mm would require a clearance of 330mm.

3.4 Flue Connection
3.4.1 General notes
This appliance may be installed with a roof terminal (C31) or a wall terminal (C11).
This appliance may only be used with Balanced Flue (otherwise known as Concentric Flue) parts as specified by
Mendip. The Mendip specified flue parts have been approved with the appliance. If the appliance is installed on
non-Mendip approved parts, Mendip cannot guarantee or accept and responsibility for the proper and safe
working of the appliance.
Approved Flue Systems are listed on Page 4.
The flue system must be constructed from the appliance upwards, with all joints being fully locked and sealed
using the Mendip specified parts.
3.4.2 Timber Frame Construction
Whilst it is possible to install room-sealed appliances in timber frame properties, great care needs to be taken
to ensure that the flue assembly does not interfere with the weather proofing qualities of any outer wall which
it may penetrate. Before attempting this work, further details need to be referenced, (e.g. “Gas Installations in
Timber Frame Buildings” from the GAS SAFE installer series in the UK).
3.4.3 Carport or Building Extension
Where a flue terminal is sited within a carport or building extension, it should have at least two completely
open and unobstructed sides. The distance between the lowest part of the roof and the top of the terminal
should be at least 600mm.
Note: A covered passageway should not be treated as a carport. Flues should not be sited in a covered
passageway between properties.
3.4.4 Basements, Lightwells and Retaining walls
Flue terminals should not be sited within the confines of a basement area, light well or external space formed
by a retaining wall, unless steps are taken to ensure the products of combustion can disperse safely at all times.
It may be possible to install this Balanced Flue system in such a location provided that it is not sited lower than
1m from the top level of that area to allow combustion products to disperse safely.
Flue terminals should be sited to ensure total clearance of the combustion products in accordance with the
included information.
When the products of combustion are discharged, they should not cause a nuisance to adjoining or adjacent
properties and they should be positioned so that damage cannot occur to other parts of the building. If the outer
wall surface is constructed of combustible material, a non-combustible plate should be fitted behind the
terminal projecting 25mm beyond the external edges of the terminal.
