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 16 for fitting and operation
and also operating instructions on fuels for correct
settings of the grate.
AIR INLET CONTROLS
Stratford multifuel stoves have three 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 primary air inlet providing under draught to
the base of the fire chamber through the gap
between the body and the ash pit door.
•Most importantly on the Stratford Boiler stoves is
the thermostatic control system.
Please note partial opening of the ash door will
over-ride and negate the thermostatic control.
THERMOSTATIC CONTROL
Stratford Tf Integral Boilers have a
thermostatically controlled side air inlet, beneath an
access plate.
The damper plate at the rear/side of the appliance
regulates the amount of under draught entering,
depending on the setting of the thermostat control
knob (located at the bottom front on the left hand
side of the unit) and the temperature of the water
transmitted through the sensor phial in the water
jacket.
Stratford Tf and Ti with the ash door fully shut,
the settings range from 0 (fully anti-clockwise) a
shut-off setting at which the damper will shut off
the underdraught completely, causing the fire to die
down and in time go out, to 8 (fully clockwise) the
highest setting at which the appliance will burn
fiercely and produce very high outputs.
For more information on the Ti inset model please
see page 20.
Note: The area around the thermostat, both inside
at the back of the firebox and externally, must be
cleared of ash and other debris regularly.
(See page 13). For setting instructions refer to
"Checking Thermostat" on page 19 .
AARROW AIR WASH 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 shaft 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.
The operating tool should be used to tap the control
shaft to the desired setting.
Fig. 1 Fully Closed Fig. 2 Fully Open
Note: Opening or part opening of the ash door is
controlled by the "interlock" device located in the
front of the unit (refer to INTERLOCK section on
page 9). Even when all the slots are completely shut
a "bleed" of secondary air will be maintained
ensuring that inflammable gases are burnt off.
DISASSEMBLE AIR WASH
The Stratford 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.
