OPERATING INSTRUCTIONS
FIREBOX LININGS & THROAT
PLATE

liners to the sides and rear) and a specially shaped
throat plate which sits on the liners. If these are not

and also operating instructions on fuels for correct
settings of the grate.
AIR INLET CONTROLS
Becton 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 primary air inlet providing under draught to
the base of the fire chamber through the gap
between the body and the ash pit door.
PRIMARY AIR FOR MULTIFUEL
On Multifuel units primary air enters the appliance
through the gap between the body and the ash pit
door. The width of the gap is controlled by rotating
the door knob (if hot, with operating tool) anti-
clockwise to increase the the air inlet, clockwise to
reduce the air inlet, or seal the ash door
completely.
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 below.

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.
