2)
Vent at back of stove, controlled by the thermostat is also a Primary air vent – the thermostat will allow air in initially
but will close when upto temperature. When burning for longer periods, or when the stove is not supervised, all other
vents shut be closed to minimum. If the water temperature exceeds safe limits, the thermostat automatically closes the
rear Primary inlet thus slowing the burn rate to help avoid boiling of the water in the system.
Before use, the operation of the thermostat should be checked when cold – turn the thermostat control dial to
minimum, to ensure that the closure plate sits flush against the stove body. If it doesn’t, it can be further tightened
with a crosshead screwdriver. Once a satisfactory closure is achieved, the control arm can then be opened ready for
use.
3)
Vent control at top of door – this is the Secondary or Airwash supply – this vent allows air in which is flushed down
onto the glass helping to keep the glass clean and aiding cleanburning of the gases. Moving slider to the left will
minimise air flow/ burn rate. Moving to the right fully opens for maximum air flow and burn rate.
4)
Vent under the stove body – this is the Tertiary air inlet and remains open – it allows air in to a channel behind the
firebox and this air is preheated and introduced into the firebox through a series of small holes at the back of the
firebox. This air supply is essential for clean burning of the fuel and gases.
