11.2 - FIRE SURROUND - SLIPS - HEARTH REQUIREMENTS (Also See diagrams in Section 11.1)
a.
If the Fire is to be fitted against a purpose made Fire Surround Back Panel it must have a temperature rating of 150
º
C.
b.
Where a Fire Surround is to be used due to the possibility of cracking we recommend that the Back Panel of the Surround is made of 3
pieces with a top and sides. Some back panel materials, (Conglomarate), claiming a 150C rating may still not withstand the temperature
variations created by this high efficient output fire and may discolour or create an odour.
c.
The Fire requires a non-combustible Hearth of 50mm high consisting of a top of at least 12mm thick.
d.
The hearth must project at least 300mm in front of the wall and have a minimum width of 700mm centrally positioned.
e.
If the Hearth as an Upstand it must not be greater than 15mm above the hearth as the controls door will not open.
f.
The wall must be flat, and square to the hearth.
g.
For Wall Installations without a Surround Back Panel or if Slips are to be used there must be a minimum flat surface central around the
flue of 630mm high by 635mm wide. This will allow for the case to fit close to the wall.
h.
There must be provision for a gas supply through the rear at the left side 65mm from the centre, see Section 10 Gas Supply.
i.
Dependant on the Control specified the fire may be fitted with Electronic Equipment, which is sensitive to dampness and high
humidity so it is
very important
that any rendering/building work is allowed to thoroughly dry out before Installation.
! IMPORTANT NOTE !
Dry lined walls - ensure that any air gaps between the back of the plasterboard and wall are sealed off
around the flue hole as heat from the flue can cause overheating of the wall, wall staining.
11.3 - FIREPLACE REQUIREMENTS
a.
The fire can be installed into a property with internal timber/studwork constructed walls, see Section 11.1.
b.
No combustible materials (e.g. Wood-Studwork) must
NOT
be closer than 110mm to the flue. This distance cannot be reduced by lining
with a Non Combustible material.
c.
Where the property as Cavity Wall Insulation this
MUST
be sealed off at least 110mm clear of the flue.
Note: A drip/weather shield should be provided above the Fireplace Opening to prevent rain/damp bridging the cavity.
d.
A Hole for the flue should be centrally cut at a height of 454mm from the top of the Hearth. See Cutting the Hole.
e.
There must be provision for a gas supply through the rear at the left side 65mm from the centre, see Section 10 Gas Supply.
f.
There must be a flat surface around the flue of 630mm high by 635mm wide to allow for the fire, see Section 11.1.
g.
A Hole for the flue should be centrally cut at a height of 454mm from the Hearth. See Cutting the Hole.
h.
The fireplace opening should have provision for a gas supply through the rear, see Section 10 Gas Supply.
i.
Dependant on the Control specified the fire may be fitted with Electronic Equipment, which is sensitive to dampness and high humidity so
it is
very
important
that any rendering/building work is allowed to thoroughly dry out before installation.
NOTE: Take Care Not To Use Materials That Will Give Off An Odour When Hot
As This Issue Is Known To Result In Complaints And Is Difficult To Resolve.
11.4 - FALSE CHIMNEY BREAST APPLICATION
a.
If it is decided to use a false Chimney Breast to accommodate the fire then the details for materials, sizes, clearances are as detailed
above and the diagrams in Section 11.1.
b.
The void around the flue must not be packed with insulation and we also recommend that ventilation openings/grilles are added to
ventilate the void of the False Chimney Breast at high and low Level.
This will allow the cooler room air to circulate around the void of the Chimney Breast, which will reduce temperatures and assist with wall
coverings applied to the Chimney Breast.
11.5 - CLEARANCES TO COMBUSTIBLE MATERIALS AND SHELVES (Ref: Diagram in Section 11.1)
No Combustible Material Must Be Closer Than 110mm To The Flue
a.
A
non combustible
shelf can be fitted above the fire and should be positioned at least 680mm above the hearth, see Section 11.1.
Please note a lower position for a shallower shelf could be used however ensure the case can be lifted off for removal.
b.
A 150mm
combustible
shelf can be fitted above the fire but must be positioned at least 750mm above the hearth.
For deeper combustible shelves they must be raised a further 25mm for every extra 25mm of depth.
c.
Any combustible sidewall must be 700mm central about the flue, however with a combustible fire surround with side walls deeper than
150mm this distance must be increased by 25mm for every extra 25mm of depth.
d.
With all heating appliances, soft furnishings, decorations and wall coverings they may discolour or scorch if placed too close.
e.
No combustible material, e.g. curtains must be closer than 500mm to the fire.
f.
Any combustible wall claddings (wall paper) must be cut back centrally about the flue to 620mm high and 560mm wide.
g.
Due to the heat output of the Veo Balanced Flue it is
not recommended
to use blown vinyl wall covering around the fire.
11.6 – CUTTING THE HOLE FOR THE FLUE
The flue is 150mm in diameter, and a hole is required providing sufficient clearance, we recommend 160mm diameter minimum.
The following Notes will assist:
a.
If cutting the hole with a core drill ensure the pilot hole is cutting into solid material as it may wander.
b.
Partially drill the hole and then check the fit of the flue before finishing,( a Wall Plate is provided for the outside).
c.
For cutting out the hole with a chisel, first pilot drill the hole centreline then mark out the hole on both inside/outside and use small
holes around the hole before cutting out with the chisel and making good the hole,( a Wall Plate is provided for the outside).
d.
Ensure the hole is horizontal, round and straight.
e.
Any Cavity Wall insulation must be trimmed and sealed back from the hole by at least 100mm to prevent contact with the flue.
f.
Any internal plaster board typical to a dry lined property should be cut back 25mm around the flue, e. g. 210mm diameter.
