OPERATING INSTRUCTIONS
MULTIFUEL GRATE
The 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 9 for fitting and
operation instructions and correct grate settings.
AIR INLET CONTROLS
HSB Boiler Stoves have three air inlets:
The air wash system (so called because
pre-heated high speed air washes across the
inner face of the glass, helping to keep
it clear) provides the over draught air for
the stove. See fig 15 & 16.
The thermostatic air control system
which is the primary source of under
draught air for the stove.
The Easy Boost air slider.
Easy Boost air slider
The
Easy Boost
air inlet slider is positioned at
the bottom of the door as pictured below.
Sliding towards the ‘
+
’ symbol increases under
grate air, towards the ‘
-
’ reduces under grate air.
Opening the slider will give a boost to the fire
during lighting, or if a rapid increase in output is
required. This control should be used for
short
periods only
and will reduce the effect of the
thermostatic control. Always close the Easy Boost
slider if the stove is to be left unattended.
Thermostatic control
HSB Boiler Stoves
have a thermostatically con-
trolled air inlet, beneath an access cover.
The damper plate at the side of the stove regu-
lates the amount of under draught air entering the
stove, dependant on the setting of the thermostat
control knob (located at the bottom front left hand
side of the stove, see image on opposite page).
The temperature of the water in the boiler jacket
is transmitted by the sensor phial located on the
upper face of the rear boiler jacket outer skin.
Partial opening of the stove door during firing
will over ride the thermostatic control and
may cause over firing.
Air wash System
The air wash control has an internal sliding plate
with apertures, housed behind the stove outer
body, and is located above the fire door.
Sliding the control to the far right will achieve the
fully open position. (See Fig. 15).
Sliding the control to the left, will shut off the
air wash inlet. (See Fig. 16).
The operating tool should be used to move the
control to the desired setting.
A permanent bleed of secondary air is arranged
within the stove body to ensure flammable gases
are burnt off, even when the air wash is in the
fully closed position.
