780 HD USERS INSTRUCTIONS

Introduction

The 780 HD has been designed and tested to the requirements of EN 613 and is suitable for use in

Great Britain & Republic of Ireland.

780 HD incorporates a single gas valve which selects ignition pilot, with variable setting between

low and high setting and is operated via remote control hand device or optional smart app

device. This system is powered by mains electricity via pre-wired transformer plus supply cord.

Alternative power supply is available for users during mains interruptions.

The 780 HD incorporates a safety device in form of an Oxygen Depletion System, which

constantly monitors the oxygen in the room and will cause the fire to switch off if the oxygen

level reduces, for instance due to insufficient ventilation or a blocked flue.

Consumer Protection Information

As manufacturers and suppliers of heating products, we take every care to ensure that the

design and construction has to meet the general safety requirements when properly used and

installed. To this end, our products are thoroughly tested and examined before despatch.

Any alteration that is not approved by the manufacturer could invalidate the approval of the

appliances, operation of the warranty and could affect your statutory rights.

This appliance could contain some materials that could be interpreted as being injurious to

health. It is the users / installers responsibility to wear protective clothing when handling the

following materials. Artificial fuel, mineral wool, insulation material, refractory/ceramic fibres and

glass yarn. May be harmful if inhaled, may be irritating to skin, eye, nose and throat.

When disposing refractory / ceramic materials to keep dust to a minimum these materials should

be securely wrapped in polythene and clearly labelled “RCF waste”. These materials are not

classified as hazardous waste and should be disposed of at a site licensed for disposal of

industrial waste.

780 HD USERS INSTRUCTIONS

Important Information

The appliance is for use on Natural Gas (G20 @ 20mbar) or LPG (G31 @ 37mbar).

The Chimney or flue (unless new or previously used with a gas appliance) shall be swept before

installation if been used for solid fuel.

In Great Britain, the appliance must be installed by a competent person whose name appears

on the gas safe register. All Gas Safe engineers should possess an ID carrying the logo below.

In IE (Ireland), the appliance must be installed by a competent person and

installed in accordance with the current edition I.S 813 Domestic Installation.

The glass front of this appliance acts as a dress guard, conforming to BS 1945 (1997) however a

fireguard to BS6539 (1997) must be used to protect young children, the elderly or infirm.

The Appliance must not be used with the glass safety screen removed or if it is damaged or

cracked.

During initial “burn off”, an odour may be evident during the first few hours of use. This is due to

the surface coating on the metal work “burning off”. The odour produced is harmless and will

disappear after a short period of time.

During the normal operation of the fire some black staining may appear on some parts of the

fuel bed. This is quite normal. However, if excessive black staining occurs it may be due to the

fuel bed shapes laid incorrectly. This should be checked prior to contacting a service engineer.

Care must be taken to prevent any damage being caused to surrounding soft furnishing or

decoration. Many embossed vinyl coverings may become discoloured if placed too close to the

appliance. It is suggested that a sample of the proposed wall covering should be placed above

the appliance at its hottest point first. The appliance should then be run on high rate over a

couple of days

It is advised that this appliance is serviced annually as recommended by Gas Safe. This is more

likely to provide trouble-free operation and is a requirement of the extended warranty.

In GB (Great Britain) the fire does not normally require purpose built ventilation, but if for any

special reason purpose built ventilation is provided it should be checked periodically to ensure

freedom from obstructions.

In IE (Ireland) permanent ventilation must comply with the current edition of IS813.

Cleaning the 780 HD Appliance

Ensure the appliance is cold before proceeding.

The outer metal work frame should be cleaned using a damp cloth.

To clean the glass panel, remove the two fixing covers and the four M4 nuts fixing the glass

clamp to the glass panel. (See Fig 8). With the nuts removed, pull the glass clamp clear of the

four studs. Finally lift the glass panel out of the bottom glass fixing.

Using a damp cloth and warm soapy water will remove a majority of stains. For more substantial

marking we recommend the use of ceramic hob cleaner. These are available from all leading

super markets. The brands of hob cleaner we have tested and found suitable are “Hob brite” &

“Bar Keepers Friend”. Ensure the glass is dry and re-assemble.

Note- Never operate the appliance when the glass panel is removed or broken. The glass may discolour quickly

when first installed, and it should be cleaned. This is due to the burning of the refractory fuel bed shapes.

To Clean the Pilot assembly. Remove the four M4 nuts and glass clamp (See Fig 8). Carefully lift

the glass panel from within the bottom location. Remove the log and bark chip shapes. Lift out

the air tray assembly from within the burner shelf.

The pilot is located on the right hand side of the appliance, remove any debris in or around the

pilot head and the aeration hole. This can be achieved using the nozzle of a vacuum cleaner. It

is advisable not to blow the debris within the pilot head or aeration hole as this may cause more

of a restriction and not rectify the problem.

Note-Take care when cleaning in this area so as not to damage the pilot assembly.
