This Hole in the Wall Application is suitable for all Trim Models without a Sealing Frame however for
the Synergy Ellesse Glass Trim Option the Glass Shelf Must be used.
This Hole in the Wall Application does not use the Nu-Flame Sealing Frames.
13.1 - SLIPS & WALL COVERINGS
It is essential to use marble, slate or stone slips, fitted around the fireplace opening. The slips must have a temperature rating of
150
º
C and we recommend that they form a border around the fire of at least 100mm. In order to direct the flow of heated air away
from the wall we recommend that a non combustible shelf (lip) is fitted above the top slip, protruding 30mm – see diagram at end of
section 12.6.
With any form of heating appliance convection air will rise up through the fire carrying particles of dust that will in time result in
varying degrees of wall staining. The non-combustible shelf is designed to minimise this by deflecting the airflow away from the wall.
However, over time some staining might occur and we therefore suggest not using patterned paper around the fire.
Due to the heat output of The Synergy Perspective BF it is
not recommended
to use blown vinyl wall covering around the fire.
Where the Chimney Breast is made of Stone or Slate or other Suitable Non Combustible Material with NO wall coverings then Slips
are Not Required but the Dimensions of the Fireplace Enclosure must be as shown below and a Flat Surface of at least 50mm must
be provided around the opening for sealing.
In this Application as Slips are being used we supply a Cable Fixing System as Drill Fixing may cause cracking of the slips, which
may not show until the fire as got hot and then cooled down over a number of operations.
Nu-Flame will not accept responsibility for Cracked Slips due to Drill Fixing

HOLE IN THE WALL APPLICATION (WHEN USING MARBLE SLATE OR STONE SLIPS)
BUILDING ENCLOSURE
a.
The fire can be installed in a suitably sized Masonry Fireplace Enclosure or suitable studwork construction, see diagrams.
b.
It is recommended that a qualified builder or joiner constructs the Building/Fireplace Enclosure.
c.
For Masonry Constructions it is recommended that a lintel is fitted above the Fireplace opening. A structural survey may be
Required.
d.
For Combustible Installations (e.g. Wood-Studwork) the Fireplace should be lined with a suitable non combustible material
(e.g. Superlux Board or Equivalent).
If the rear wall is also Combustible the Fire back must also be insulated.
e.
No
combustible materials (e.g. Wood-Studwork) must be closer than 50mm to the fire and therefore the size of the Fireplace
should cater for this, see diagram for minimum sizes. The Front Opening sizes should be as shown in the diagram.
f.
The base of the fireplace enclosure must be flat, level and square to the wall and it
MUST
be strong enough to support the fire.
g.
Where the cavity forms part of the Fireplace Enclosure this MUST be Sealed off with either a Non Combustible Material or with
a Combustible Material set at least 50mm away from the Fire. Note: A drip/weather shield or equivalent should be provided
above the Fireplace Enclosure to prevent rain/damp bridging the cavity.
h.
A Hole for the flue should be centrally cut at a height of 540mm from the base of the Enclosure. See Cutting the Hole.
i.
The Fireplace Enclosure should have provision for a gas supply through the rear, see Section 10 Gas Supply.
j.
There must be a flat surface around the face of the Fireplace opening of sufficient area to enable the slips to be fitted. The slips
must be square to the fireplace enclosure.
k.
The
recommended
height for the base of the Fireplace Enclosure is 350mm above floor level. The
minimum
height for the base of
the Fireplace Enclosure is 250mm above floor level.
l.
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 fireplace enclosure or fireplace as this can affect the fires efficiency and cause wall staining.
! IMPORTANT !
When fitting the slips ensure they are flush and form a flat surface around the fireplace opening.
