This Focus gas appliance is a High Efficiency, Balanced Flue Live Fuel Effect appliance. It provides radiant and convected heat using the latest burner technology.

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 unremovable.

Do not operate this appliance if the glass panel has been broken (or cracked), removed or with firebox access panels open.

Only flue approved by Focus 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.

On the Grappus, the control valve is located behind the control hatch in the “Log Box”. On the Slimfocus, the control valve is located in the foot of the appliance, at the rear.

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.

User instructions

Page 9

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.

GAS CONNECTION

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.

APPLIANCE 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.

This appliance must be securely fixed to the floor using the fixings built into the base of the appliance.

Do not make any adjustments to the appliance.

The appliance and Flue system should be fitted with a minimum clearance of 500mm from any combustible objects or materials; this includes any combustible materials used for the fireplace construction.

As this is a room sealed appliance and the appliance stands appropriately and is securely fixed to the floor, a hearth is not required for this appliance. A gap of 100mm should be left all round the appliance.

FLUE CONNECTION

A. 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 Focus. The Focus specified flue parts have been approved with the appliance. If the appliance is installed on non-Focus approved parts, Focus cannot guarantee or accept and responsibility for the proper and safe working of the appliance.

The flue system must be constructed from the appliance upwards, with all joints being fully locked and sealed using the Focus specified parts.

B. 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 CORGI installer series in the UK).

C. 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.

D. 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.
