1.3 FIREPLACE / SURROUND SUITABILITY
The fire is suitable for hearth mounting or wall mounting. It must not be fitted
directly onto a carpet or other combustible material. It must not be fitted to com-
bustible walls.
This fire is suitable for the following hearth / surround types:
Non-combustible hearths / surrounds.
Purpose made proprietary hearths / surrounds with a minimum temperature rating
of 150oC.
If a heating appliance is fitted directly against a wall without the use of a fire-
place or fire surround, soft wall coverings such as wallpaper, blown vinyl,
etc. could be affected by the heat and may, therefore scorch or become dis-
coloured. Please bear this in mind when installing or decorating.
1.4 SHELF POSITION
The fire may be fitted below a combustible shelf providing there is a minimum dis-
tance of 200 mm above the top of the fire and the shelf does not project more than
150 mm. If the shelf overhangs more than 150 mm the distance between the fire
and the shelf must be increased by 15 mm for every 25 mm of additional overhang
over 150 mm.
1.5 SIDE CLEARANCE
A minimum clearance of 70mm should be allowed on either side of the fire for
servicing. Any fire surround uprights should not project forward by more than
100mm.
NOTE. The fire must be installed so that no part of a combustible side wall when
measured laterally is less than 500mm from the radiants.
1.6 CLOSURE PLATE
A closure plate is supplied with this fire and must be fitted. The closure plate must
be sealed to the fireplace or surround opening with suitable adhesive tape. See
section 2.2.2
1.7 FLUE / CHIMNEY INSPECTION
Before commencing installation, a flue or chimney should be inspected to ensure
that all the following conditions are satisfied.
a) Check that the chimney / flue only serves one fireplace and is clear of
any obstruction. Any obstruction. Any dampers or register plates must
be removed or locked in the open position.
5

Supplied By www.heating spares.co Tel. [phone]
b) Brick / stone built chimneys and any chimney or flue which has been
used for an appliance burning fuel other than gas must be thoroughly
swept. The base of the chimney/flue must also be thoroughly cleared of
debris etc.
Any under floor air supply to the fireplace must be completely sealed off.
Ensure that the inside of the chimney/flue is in good condition along its length and
check that there is no leakage of smoke through the structure of the chimney dur-
ing and after the smoke pellet test.
With pre-cast flues it is especially important to check the inside of the flue
for extruded Cement / sealant protruding from the joints between the flue
blocks. If present, these should be removed by rodding the flue before pro-
ceeding with the installation.
Using a smoke pellet, check that there is a positive up draught present in the
chimney / flue and that the smoke can be seen issuing from the terminal / chimney
pot outside. There must be no leakage of smoke through the structure of the chim-
ney during or after the smoke pellet test and it is important to check inside upstairs
rooms adjacent to the chimney / flue. Check the chimney pot / terminal and gener-
al condition of the chimney brickwork or masonry. If the chimney or flue is in poor
condition or if there is no up draught do not proceed with the installation. If there is
a history of down draught conditions with the chimney / flue, a Advantica tested
and certified flue terminal or cowl suitable for the relevant flue type should be con-
sidered.
A spillage test must always be carried out during commissioning of the
appliance.
1.8 CHIMNEY CATCHMENT SPACE.
1.8.1 Brick Built Chimneys.
The catchment space below the flue spigot should be as deep as possi
ble, and must not be less than 250mm measured from the bottom of the
flue spigot to the bottom of the catchment space, or to the top of any
“bricking-up” of the fireplace, whichever is the least. See Fig. 1.
The flue spigot must pass through the closure plate at least 25mm and
have a minimum clearance of 50mm between its open end and the
nearest obstruction. There must be a minimum clearance of 165mm
between the back of the closure plate and the back of the catchment
space. See Fig. 1 overpage.

Supplied By www.heating spares.co Tel. [phone]
The front opening of the fireplace must be between 305mm and 440mm
wide, and between 470mm and 650mm high. If the opening is larger
than this, then a surround must be constructed in a suitable non-com
bustible material to create an opening to these limits. Allow a minimum
flat surface of 20mm around the opening to ensure that the closure
plate can be sealed to the fireplace.
Any surround must be sealed to the fireplace to prevent leakage. The
operation of the chimney should be tested a detailed as in section 1.7.
Note. A flue spigot extension of up to a maximum total length of 125mm
may be fitted if necessary, providing that a minimum clearance
50mm between its open end and nearest obstruction is always
maintained.
