Automatic Combustion Control
30°
Lift off the rear panel.
On a cold stove, the starting point of the mechanism is controlled. The starting point on a cold stove is about
30° above horizontal.
It should move easily and spring loaded when you push it, no matter if the stove is cold or hot.
With a rising or falling temperature it should move gradually.
The damper plates must be dry and clean and slide together unhindered.
Control bars and slide gates may have to be lubricated with a proprietary lubricant such as WD40 or a PTFE
based product such as Amberglide.
Insulation (Skamolex)
The mica board insulation material of the combustion chamber may, in time, become worn and damaged.
Cracks in the insulation have no effect on the efficiency of the stove. The insulation should be replaced,
however, when it is reduced to less than half the original thickness due to wear and tear.
Maintenance Instructions
Flue Draught Measurement
A flue draught which is too low will result in the stove being difficult to light, responding only
slowly to demands for increased output and unable to reach its full heating output. If this is
the case rectification work of the chimney construction should be undertaken. A flue draught
which is too high will cause difficult control conditions, and makes it possible to over fire
the stove, which can seriously damage it. In this instance a flue draught stabiliser may need
to be fitted or if it is wind assisted excessive flue draught a stabilizing cowl may need to be
fitted.
The negative pressure created within the combustion chamber of the stove must be
measured using a test hole drilled into the flue, as close to the stove as possible and before
any draught stabilizer that may be fitted to the flue. To ensure a constant air inlet size the
readings should be taken with the air inlet controls set at maximum.
