8.1. Flue Damper Control
The damper control varies the size of the throat in the fireplace, serving
two purposes:
(a) Provides control over the burning rate of the fire and therefore the
consumption rate of the fuel.
(b) Reduces the heat-loss up the chimney, thereby improving efficiency.
The fire in the Jetmaster is lit with the damper fully open to promote
maximum draw from the fire. When the fire is burning well the damper can
be closed down (using the poker provided) to a position that will allow the
fire to burn at the desired rate without smoking. This position will be
determined by the draw on the chimney, the type and size of the fuel being
burned and the desired size of the fire.
NOTE: Open position of damper
(a) Universal models - forward (handle L/H side)
(b) Hex models - damper handle vertical (at rear of flue)
(c) Heron models - rear (handle middle)
(d) All other models - to rear (handle centre)
Because each chimney has its own peculiarities, the damper should be
used as best suits your chimney. It should never be closed so far as to cause
the least trace of smoke in the room.
8.2 Lighting the fire (Solid fuel)
(a) Superjet (rear blower) and jetgrate (portable front blower) models:
! Ensure that grate is right back against the back-plate.
! To lay the fire, crumple sheets of dry newspaper, place dry split
wood criss-cross on top of the paper, leaving plenty of air space
between the pieces.
DO NOT add solid fuel (wood) at this stage.
NOTE: A firestarter may be used in place of the above procedure.
! Before lighting, open damper fully (refer Point 1).
! Light the paper or firestarter and switch on the fan.
! When the wood is burning well, slowly add fuel, limiting the
quantity so that the flames are kept alive all the time.
! With the grate fully fuelled and the fire burning brightly (after
approx. 40 mins.), the fan can be switched off. (Removed in the
case of the Jetgrate to prevent heat damage).
