OPERATING INSTRUCTIONS

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.

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.

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 .

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.
