for a minimum heat output and burn rate rotate the
spin valve clockwise until fully closed. For nominal
heat output the spin wheel will need to be open
between 1 and 2 turns depending upon the draught
of the chimney. You will soon learn spin valve set-
tings to best suit your requirements. (See Fig.6)

RECOMMENDED FUELS

This appliance has been tested using seasoned
wood logs only. Other fuels are commercially avail-
able and may give similar results. Do not use fuels
with a Petro-coke ingredient as this may cause the
grate to overheat, causing damage. Reduced out-
puts will result when fuels of lower calorific values
are used.
All fuels should be stored under cover and kept as
dry as possible prior to use.
This stove has obtained HETAS Ltd approval as an
intermittent operating appliance for burning natural
wood logs only as the recommended fuel. HETAS
Approval does not cover the use of other fuels either
alone or mixed with the recommended fuel, nor does
it cover instructions for the use of other fuels.

RE-FUELLING

Riddle the fire by connecting the grate operating tool
onto the rocker connection located at the bottom
front of the stove, then gently pull and push the
rocker arm until all dead ash has fallen through into
the ashpan. Before opening the door, open the spin

valve by turning it anti-clockwise, as this will help to
eliminate any smoke or fly ash resident in the com-
bustion chamber. Add fuel to fire, taking care not to
overfill higher than the front firebars. Close fire door
and re-set spin valve to required setting. Do not
operate this appliance with the fire door open. (See

SLOW BURNING

To achieve a low burn rate, close the spin valve fully,
then open about half a turn, or less, depending on
draught conditions. If the fuel load is too small or the
draught too strong the spin valve may need to be
closed even further to sustain the low burn rate.
This will be found by trial and error by adjusting the
amount of air depending upon the amount of fuel left
over at the end of the burning period.
