manual handling.
•Always obtain assistance when lifting the
appliance.
•When lifting always keep your back straight. Bend
your legs not your back.
•Avoid twisting at the waist. It is better to
reposition your feet.
•Avoid upper body/top heavy bending. Do not
lean forwards or sideways when handling the fire.
•Always grip with the palms of your hands.Do not
use fingertips for support.
•Always keep the stove as close to the body as
possible. This will minimise the cantilever action.
•Use gloves to provide additional grip.
THE PRINCIPLE OF THE FIRE
Your Aarrow Fire is built to the highest standard of
craftsmanship using the best materials and the most
modern equipment available. It is a highly efficient
and sophisticated piece of machinery and when
properly installed and operated it should provide a
lifetime of heating satisfaction.
Safety is the most important consideration when
installing your fire. If not properly installed and
operated a house fire may result. Installation must
comply with the Building Regulations and conform
to all relevant fire safety standards.
Aarrow Fires produce a variety of appliances
ranging from units, which are traditional in style to
stoves which are modern in appearance, all
bristling with "High Tech" features.
Model types include simple room heaters,
convectors, integral boiler models and inset units.
Your Aarrow Fire is constructed from either single
or twin wall steel strengthened where necessary.
Cast iron is used where appropriate for long life.
All fire doors are fitted with special high
temperature ceramic glass panels through which
the fire can be viewed.
Multifuel stoves are fitted with a cast iron grate to
give full multifuel facility and positive de-ashing.
All models except integral boiler models are lined
with firebricks or heat reflective panels which
ensure complete combustion and provide a good
heat store to even out fluctuations in burning.
An internal throat plate produces turbulence to
encourage secondary combustion and directs the
flue gas around the whole upper firebox before
allowing it to escape up the chimney.
On multifuel appliances the primary air for burning
enters the ash pit chamber beneath the grate,
controlled by the air inlet mechanism.
Aarrow Fires are also fitted with an "air wash" so
called because it provides a curtain of high speed
preheated air behind the glass to help keep it clean
and to provide secondary air/over draught.
The provision of two inlets on all multifuel stoves
gives a wide range of primary air/secondary air,
under draught/over draught combinations. The
optimum settings will only be established by
experience in firing the appliance, and will depend
on type of fuel, the position of the appliance in the
house, condition of chimney etc.

Inside the appliance you should find the following:

FIREBOX LININGS & THROAT
PLATE
The Apex Multifuel stoves firebox has reflective
liners to the sides and rear and a specially shaped
throat plate which sits on the liners. If these are not
in place please refer to page 16 to install these.
MULTIFUEL GRATE
The Aarrow Multifuel grate comprises of a series of
reciprocating cast iron bars seated on a pivoted
"comb". These should come fitted in your stove, if
not please refer to page 17 for fitting and operation
and also operating instructions on fuels for correct
settings of the grate.
AIR INLET CONTROLS
Apex multifuel stoves have two air inlets:
•The air wash system (so called because its
pre-heated high speed air washes across the inner
face of the door glass, keeping it clear), which
provides over draught, and
•The lower set of holes; the primary air inlet
providing under draught to the base of the fire
chamber through controls on the bottom of the
stove door.
PRIMARY AIR FOR MULTIFUEL
Air enters the appliance through the control on the
bottom of the fire door. The Aarrow Apex has a
single control knob which slides left to right.
Sliding the knob to the right will increase the
amount of air intake to the stove. To decrease push
knob to the left.
AARROW AIRWASH SYSTEM
The air wash has an internal sliding plate with slots,
housed in a cover plate, and is located above the fire
door. Sliding the control knob to the right as far as it
will go achieves the fully open position. Sliding it to
the left will shut off the air inlet slots As shown in
figures 1 and 2.
Fig. 1 Fully Closed Fig. 2 Fully Open
Even when all the slots are completely shut a
"bleed" of secondary air will be maintained
ensuring that inflammable gases are burnt off.
DISASSEMBLE AIRWASH
The Apex air wash may be disassembled for
cleaning or adjustment. To achieve this, the
following procedure should be followed:
This should only be carried out when the fire is cold
and unlit.
•Support Air Wash cover with one hand.
•Move cover up by smartly tapping the bottom with
a hammer. (Fig. 3)
Remove assembly from appliance.
•Clean and/or adjust.
•Refit using reverse procedure.
