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.
14.1 - SLIPS & WALL COVERINGS
It is essential to use marble, slate or stone slips, fitted around the builders 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 see Section 7b to determine the Slip sizes to
match the Trim being used. In order to direct the flow of heated air away from the wall with the Steel or Glass Trims Options we
recommend that a non combustible shelf (lip) is also fitted above the top slip, protruding 30mm – see diagram in section 13.4.
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 Range it is
not recommended
to use blown vinyl wall covering around the fire.
Where the Chimney Breast is made of Stone, Slate or other Suitable Non Combustible Material with NO wall coverings then Slips are
Not Required but the Dimensions of the Builders Opening must be as shown below and a Flat Surface as detailed in Section 8b will be
required for the Trim Option being considered to allow the Trim to be fitted and provided a flat area around the opening for sealing.
In this Application as Slips are being used we supply a Cable Fixing System as Drill Fixing may result in 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.
14.2
HOLE IN THE WALL APPLICATION (WHEN USING MARBLE SLATE OR STONE SLIPS)
a.
It is recommended that a qualified builder constructs the
builders opening.
b.
It is recommended that a lintel is fitted above the builders
opening, structural check may be required
c.
The builders opening must be constructed from
Non-combustible materials.
d. No
combustible materials must present in the builders
opening.
e.
The base of the builders opening must be flat, level and
square to the wall.
f.
The builders opening should have provision for a gas
supply through the rear, see Section 11 Gas Supply.
g.
There must be a flat surface around the builders opening of
sufficient area to enable the slips to be securely fitted. The
slips should be fitted to the wall in such a way that they form
a seal to stop air from the room being drawn behind the slips
into the builders opening.
We recommend a high temperature silicon sealant.
h.
The
recommended
height for the base of the Builders
Opening is 400mm above floor level. The
minimum
height
for the base of the Builders Opening is 250mm above floor
level.
i.
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.
Note: The builders opening can taper towards the back to a minimum of 750mm and must be 300mm deep.
! 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.
! IMPORTANT !
When fitting the slips ensure they are flush and form a flat surface around the builders opening.
14.3 - CLEARANCES TO SHELVES & COMBUSTIBLE MATERIALS
a.
We do not recommend the use of a combustible shelf in this application.
b.
We do not recommend the use of a non-combustible shelf in this application other than the non combustible shelf /lip mentioned
in section 13.1 and the diagram shown in 13.4.
c.
Any combustible sidewall must be at least 500mm from the inside of the builders/fireplace opening.
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.
