Information on Smokeless Fuel (Ancit) burning
Ancit, briquetted smokeless and coal type fuels require very different burning conditions to log
burning and the single air control has been designed to allow for this. Use the control on the
right side of its travel marked ‘Coal’ for best efficiency on these types of fuel. Ancit and other
smokeless briquetted fuels can burn with very little primary air and stay in for many hours to be
revived after an overnight burn for example.

Lighting the Stove
We recommend that you have two or three small fires before you operate your stove to its
maximum heat output. This is to allow the paint to cure in steadily and to give a long service life
of the paint finish. During this curing in process you may notice an unpleasant smell whilst the
finishes finally cure. It is non-toxic, but for your comfort we would suggest that during this
period you leave all doors and windows open.
First, open the single air control fully. Then load the firebox with plenty of starting fuel, i.e.
paper, dry kindling sticks and/or firelighters. A crib lattice pattern or wigwam pattern tend to
work well. If using Ancit, place a layer of ancit into the firebox as well. Light the fire at the base
leaving the air control fully open. Leave the door ajar for 5-10 minutes to enhance initial starting
and reduce smoke emission – DO NOT leave the stove unattended if the door is left ajar. Allow
the fuel to reach a steady glow and build the fire up gradually by adding a few small well split
logs or Ancit briquettes at a time. Once you have a good fire bed established across the grate,
further fuel can be added step by step as required. Don’t be tempted to overload the fire bed
with fuel all at once or close down the air controls until the fire is really well established for
some time. Once the ignition period is well under way, gradually reduce the air control opening
to establish the burning intensity you require.

Re-fuelling
When burning Ancit the fire will begin to die down with a significant amount of white ash
showing amongst the fuel. Shake the grate using the shaker and then
gently
run a poker
through the fire bed to remove most of the ash into the ashpan. Empty the ashpan if it is nearly
full and then re-fuel with a good load of briquettes. The fuel load should initially be level with
the top of the fuel retainer and not above the rear firebox liner tertiary air inlet profiling. Whilst
approval test cycles are 1 or 2 hours, a stove burning Ancit may be kept in overnight easily
under normal conditions.
When burning wood, the fire will die down as the fuel is consumed. When the flames disappear
and the remainder is breaking down into glowing embers it is an appropriate time to consider
re-fuelling. NOTE: If the flames disappear and there are still lumps of solid wood left this
indicates excessive internal moisture in the wood or insufficient air supply/flue draught.
NOTE:
To eliminate unwanted smoke emission, after loading new logs on to the fire, open the
air wash control up fully for 3 minutes or until the logs are blackened all over to boost the fire
and get flames issuing from the top of the fuel as soon as possible. When flames are well
established, reduce the air wash to the running setting required.
Burning without flames above
the fuel will create unnecessary smoke
. Do not load fuel above the tertiary air inlet hole
profiling at the back of the firebox.
Loading 1 or 2 large sized logs will produce a good output with reasonable burn time. Small logs
will burn up quicker producing a high output and more emissions for a short time, and a large
log will take longer to burn and produce less output and less emissions over a given time. These
appliances are approved for intermittent operation on wood (0.75 to 1.5 hour burn cycles)
