General; Installation Requirements; Fire Location; Check The Chimney - Potterton Hallmark Installation & Service Instructions Manual

2. General - Page 3
The Hallmark is an Radiant Convector gas fire, it is lit by a piezo spark igniter so batteries or electricity are not required.
The radiant heat is created by the use of ceramic radiants mounted centrally below the convector box.
IMPORTANT: Certain types of wallcoverings e.g. Blown Vinyl, are easily affected by heat. They may shrink and
discolour when close to a heating appliance. Please bear this in mind when installing the fire. Also,
because of the way hot air circulates naturally convected heat from the fire, dust or tobacco smoke
particles in the air will draw towards the wallcovering around the fire and may discolour it.
IMPORTANT: This fire MUST NOT be installed without its Closure Plate.
If you have any problems or questions concerning this appliance, please contact the Potterton Myson Technical
Help Line - Telephone (01926) 410044.

3.1. Fire Location

The fire may be floor or wall mounted. The depth of the fireplace opening being a minimum of 165mm and the height to the
base of the spigot being a minimum of 250mm. A clearance of 50mm minimum between the end of the spigot and the
chimney. See Fig. 2.
A space of 765mm wide x 700mm high is required for installation. The height can be reduced where non combustible
materials are used. See Fig. 4.
A floor mounted fire must be on a non combustible hearth measuring at least 762mm wide and 305 deep. The hearth
material should be at least 12mm thick, see Fig. 3. Its top surface should be preferably be 50mm above the floor level in
order to discourage the placing of a rug over it. The fire MUST NOT be fitted directly onto a combustible floor. The fire is
suitable for installing in a normal brick chimney or a properly constructed Pre-Cast Flue.

3.2. Check The Chimney

a) The chimney must be swept immediately prior to
installation.
b) Remove any damper or register plate.
c) Any air supply e.g. underdraught openings etc., that
enter the fireplace other than via the closure plate
MUST BE COMPLETELY SEALED OFF.
d) Check that the chimney serves only one fireplace and
the base of the flue is clear of debris, bricking up etc.
e) Check also that the fireplace opening and the flue are
properly sealed so that combustion products do not
come in contact with combustible material outside the
flue passage.
f) Check for flue pull by applying a lighted taper, match or
smoke match into the fireplace opening. If there is a
definite flow into the opening proceed with the
installation. If not, pre-heat the flue for about 2 minutes
and re-check. If there is still no definite flow the flue may
require attention, so:
DO NOTPROCEEDANYFURTHER WITH THE
INSTALLATION UNTIL EXPERT ADVICE HAS BEEN
SOUGHT.
