This Application does not require the Sealing Frames & with the Synergy Perspective Glass, the Glass Shelf.
For This Application a Riser Plate is Fitted That Raises The Fire To Enable The Door To Be Opened
Therefore The Fireplace Opening is 30mm Higher.
In this Application as a fire surround is being used we supply a Cable Fixing System as Drill Fixing may result in cracking of
the back panel, which may not show until the fire has got hot and then cooled down over a number of operations.
Nu-Flame will not accept responsibility for Cracked Back Panels due to Drill Fixing.
15.1
FIRE SURROUND APPLICATIONS
Notes: There must be no combustible materials inside the builders opening.
The builders opening can taper towards the back to a minimum of 750mm and must be 300mm deep.
15.2 - FIRE SURROUND REQUIREMENTS
a.
If the Fire is to be fitted into a purpose made Fire Surround it must have a temperature rating of 150
º
C. Take care with some
micro marbles and the adhesives used claiming 150
º
C rating as they can be prone to blistering and can give off odour.
b.
The Fire requires a non-combustible hearth of at least 12mm thick.
c.
The surface of the hearth must stand at least 50mm above the floor and level with the fireplace opening.
d.
The hearth must project at least 300mm in front of the fireplace opening and 150mm either side (1080mm minimum width).
e.
The base of the fireplace must be flat, level and square to the face of the fireplace opening.
f.
There can be
no
up stand around the hearth as the door of the fire has to be opened.
g.
The surround must cater for a minimum flat surface around the Fireplace Opening allowing 100mm above the opening and 125mm
on each side. This is essential in order to achieve a good seal between the face of the Surround back panel and the Fire sealing
Flange.
h.
The 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 !
Dry lined walls – ensure that any air gaps between the back of the plasterboard and wall are sealed around
the builders opening or fireplace as this can affect flue pull and wall staining.
15.3 - CLEARANCES TO SHELVES & COMBUSTIBLE MATERIALS (Ref: Diagram Above)
a.
A
non combustible
shelf can be fitted above the fire and should be positioned at least 95mm above the builders opening. We recom-
mend the depth of the shelf should be a maximum of 75mm as anything deeper will reduce convection air and the
efficiency of the fire. For deeper non-combustible shelves they must be raised a further 25mm for every extra 25mm of depth.
b.
A 150mm
combustible
shelf can be fitted above the fire but must be positioned at least 350mm above the builders opening.
(1025mm minimum from base of fireplace opening). 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 combustible fire
surround it can be 150mm from the inside of the builders/fireplace opening provided it does not protrude more than 150mm and
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.
No combustible material, e.g. curtains must be closer than 500mm to the builders opening.
f.
Any combustible wall claddings (wall paper) must be cut back to the perimeter of the shelf and slips or to a height of 875mm and
140mm either side of the Fireplace Opening.
