LIGHTING THE FIRE
Prior to lighting the fire for the first time check
with the installer that:
•Installation and all building work is complete.
•The chimney is sound and has been swept and is
free from obstruction.
•Adequate provision for combustion air has
been made, i.e. a permanent vent of at least
550mm² per kW of rated output above 5 kW,
is fitted in the room in which the appliance
is installed.
•That Building Regulations and any local
by-laws have been followed during installation
(see installation instructions).
•All firebox liner panels are in place.
•Throat plate is in place.
•That the chimney draw has been checked and is
within specification. With the chimney warm the
draught should be between 1 - 2mm water gauge
(0.1 - 0.2mbar).
WARNING: An over drawing chimney can cause
over-firing resulting in damage to the appliance.
ENSURE THAT YOU HAVE READ &
UNDERSTOOD THESE INSTRUCTIONS
BEFORE LIGHTING THE FIRE.
ALWAYS WEAR SUITABLE PROTECTIVE
FIRE GLOVES WHEN REFUELLING YOUR
STOVE.
SOLID FUEL BURNING - Multifuel Stoves
•Ensure that the multifuel grate and ash pan are in
position and the fire doors are closed.
•Set the air wash to one quarter open position.
•Set the primary inlet to the fully open position
•Light in the normal manner with paper and
kindling, or use a fire lighter.
•If using a gas poker be sure to remove it
immediately the fire is alight.
•When the fire is well alight regulate the burning
rate by adjusting the setting on the primary air
inlet control.
•The air wash can be opened sufficiently to keep
the door glass clean.
BURNING WOOD
•Set air wash to the fully open position
•Proceed as for solid fuel but note the fire will burn
up and become established more quickly.
MIXED FUELS
•As per coal but allow additional secondary air.
•The primary air inlet can be closed and burning
regulated by means of the air wash above the door.
ANTHRACITE
Anthracite is more difficult to keep in for long
periods, consequently more care in setting the
controls and some familiarisation is necessary
when burning anthracite.
Use the smallest size fuel (Stovesse or Small Nuts).
Proceed as for manufactured smokeless fuel. Leave
the air inlet control open about a quarter or less.
Note: The high temperature paint acquires
durability by being "cured" during the initial
firings of the appliance will give off fumes which
are non-toxic, but which certain persons may find
have an unpleasant or irritant effect. Ensure that
the area is well ventilated during this time.
EXTENDED BURNING
The appliance will burn for an extended period
provided:
•Sufficient fuel is placed in the firebox.
•The controls are set correctly.
•Excess draught is not present in the chimney.
•Fire door is closed.
•If the fire goes out with unburnt fuel left in
the firebox increase the air opening slightly,
and vice versa.
