11B. PRIMARY AIR
The ash pit door is to be used to introduce initial combustion air when the stove
is started from cold or re-fuelled with its body temperature below 150°C on the
top plate.
The ash pit door must be drawn out 3-5mm to allow draft until the top plate has
reached 150 degrees centigrade and then closed and the air wash control
takeover. (see 11C.)

11C. SECONDARY AIR (AIRWASH)
After Stoves top plate has reached 150°C. the ashpit should be closed whereby the preset (fixed)
Secondary air (airwash) system will continue combustion (from the rear of the stove via the tubed baffle
system).
The airwash in conjunction with the tertiary air supply will produce clean combustion and clear any the
majority of blackening on the door glass apart from a band at the top or fly ash deposits on the inner
face of the glass (when the stove reaches 150°C or above).
It is important to note that the stoves performance is directly relative to the flue chimneys draft. The
stronger the draft the faster the stove will heat from cold and respond to the air controls.
Excessive draft will cool the stove faster when combustion is finished (draft should not be above .06
water gauge).
11C (1) SECONDARY AIR (AIR WASH) AND OUTSIDE AIR OPTION MODEL 678EC
No controls need to be altered for secondary airwash air to operate as the rear back plates transfer this
air to the secondary air ports automatically when the control lever (horizontal knob handle) is in the
tertiary air position(far right). The action of moving the knob handle to the right closes the primary air
leaving the secondary air permanently open.
11D. OUTSIDE AIR
Outside air is an extra option. When fitted the appliance draws its combustion air predominantly from
outside, therefore reducing drafts to the room in which the appliance stands. This air is preheated
before being delivered into the same points of combustion as with the standard stove operation 1)
primary air to beneath the grate bed 2) secondary air down the face of the glass and tertiary air through
the same rear pre-
drilled back boards. The combustion characteristics haven’t changed.
