e.
When building a False Chimney Breast No Combustible materials must be closer than 50mm to the Flue Box.
f.
No Combustible materials must be closer than 50mm to the Twin Wall Flue over its entire route through the Property.
g.
The Flue Box must be Insulated on its top and sides with 50mm thick Non Combustible Fibreglass Insulation or Equivalent.
h.
If plaster board is used in front of the flue box it must be sealed to the box with high temperature Silicone Sealant or an equivalent
flexible sealant.
i.
If the Fire is to be fitted with a purpose made Fire Surround it must have a temperature rating of 150
º
C.
j.
The Fire requires a non-combustible hearth with an upper surface of at least 12mm thick.
k.
The surface of the hearth must stand at least 50mm above the floor and level with the fireplace opening.
l.
The hearth must project at least 300mm in front of the fireplace opening and 150mm either side (700mm minimum hearth width).
m.
The Surround must cater for a minimum flat surface around the Fireplace Opening allowing 630mm high by 630mm wide.
This is essential in order to achieve a good seal between the face of the surround and the sealing flanges of the fire.
n.
The Fire Surround must be fully sealed to the Fireplace Opening to ensure a good flue seal.
o.
The Fireplace Opening should have provision for a gas supply through the rear, see Section 10 Gas Supply.
p.
The Thermatronic fire is 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 !
Do not forget to take account of the difference in height of the base of the Flue Box when mounting the
box on the floor; it must be level with the Hearth.
13.3 - CLEARANCES TO COMBUSTIBLE MATERIALS AND SHELVES (Ref: Diagrams on Page 19)
a.
For Fire Surrounds with a 150mm
non combustible
shelf it must be fitted above the fire at least 680mm above the hearth.
For deeper non-combustible shelves they must be raised a further 25mm for every extra 25mm of depth.
b.
For Fire Surrounds with a 150mm
combustible
shelf it must be fitted 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 at least 500mm from the inside of the builders/fireplace opening, however with a non combustible
fire surround it can be 250mm from the inside of the builders/fireplace opening provided it does not protrude more than 150mm
and this must be increased by 25mm for every extra 25mm of depth.
d.
With all heating appliances, soft furnishings, decorations and wall coverings may discolour or scorch if placed too close.
e.

f.
Any combustible wall claddings (wall paper) must be cut back to a height of 750mm and 300 mm either side of the Fireplace
Opening.
g.
Due to the heat output of The Fenton CF it is
not recommended
to use blown vinyl wall covering around the fire.
