NOTES FOR THE INSTALLER AND END USER
5
T
his fire is a very effective heating appliance and must be fitted against a wall of non-combustible material as
classified in BS 476-4:1970 (2007).
All parts of the appliance become hot while running and should therefore be considered to be working surfaces.
An air vent is not required for this application. Both appliances have been tested without the need for additional
air requirements.
W
e recommend that if the chimney/flue has been used for solid fuel, it is swept prior to installation of this
a
ppliance and that any flue restrictor or damper plate should be removed.
The chimney/flue must always generate a positive up draught to ensure safe operation.
The installer must then establish that all the products of combustion are entering the flue within ten minutes of
lighting from cold. This can be verified by inserting a lit smoke match into the central duct immediately above the
door. It should NOT be inserted into the left and right convector ducts.
T
his operation should be carried out before fitting the trim so no staining occurs (see ‘Spillage Test’ page 6).
A
n isolation valve must be fitted adjacent to the appliance. When closed, this will allow the complete burner and
control assembly to be disconnected for maintenance or repair in accordance with national regulations.
The gas supply should be provided by a semi rigid pipe with an 8mm diameter and should be no longer than 1.5
metres in length.
NOTE: When the gas supply pipe is passed through masonry or other brickwork always ensure that the end
of the pipe is covered to avoid any debris passing through into the appliance controls.
The appliance is fitted with an Oxygen Depletion Sensor (ODS) that monitors the room for products of
combustion. If products are detected, the ODS will automatically shut down the appliance. If this situation
arises, re-light the appliance, referring to the user instructions (page 20).
If shut down re-occurs, a qualified person must be called to thoroughly check the appliance. The spillage
monitoring system (ODS pilot) must not be put out of operation or be tampered with or adjusted by either the
installer or the user. If the unit is found to be at fault it should be replaced with the manufacturers original
replacement parts.
INSTALLATION REQUIREMENTS
This appliance must only be installed in Great Britain or Ireland.
1. This fire is a natural gas appliance and has been designed for use with the following applications:
a) Class I - Conventional brick or stone chimney as used for a solid fuel fire with a cross sectional dimension of
225mm x 225mm (9” x 9”) or a lined flue with a minimum diameter of 125mm (5”), with the fireplace components
conforming to BS1251, or a builders opening a minimum of:
Ethos Landscape - 466mm high and 757mm wide with a minimum depth of 325mm
Ethos Portrait - 622mm high and 757mm wide with a minimum depth of 325mm
to allow sufficient volume for debris collection (unlined chimney 12 dm3 and lined 2 dm3). Any permanent flue
restrictions or variable dampers are to be removed or locked in the fully open position.
The chimney should also
be swept prior to installation.
b) Class II -
An insulated flue (twin wall) having a minimum diameter of 125mm (5”) and a minimum ef
fective
overall height of 3 metres (10’).
NOTE: If the fire is to be used with an existing brick or stone chimney, a 125mm (5”) minimum diameter flue
liner conforming to BS715 may be used.
2. Care should be taken to prevent any damage being caused to surrounding soft furnishings or decoration, e.g.
many embossed vinyl wall coverings may become discoloured if placed too close to the appliance.
3. A suitable proprietary fire surround with 100°C rating may be used with a minimum clearance from hearth to
underside of shelf of 830mm, providing that the depth of shelf is 150mm or less. It is recommended that
combustible materials are not placed directly above or adjacent to this appliance.
