OPERATING HINTS FOR CLEAN BURNING AND BEST EFFICIENCY
FUEL: USE ONLY WOOD THAT HAS BEEN AIR DRIED IN A SHELTERED WELL
VENTILATED STACK, PREFERABLY FOR AT LEAST 12 MONTHS. In all Clean
Air Zones in New Zealand, only wood may be used as fuel, and it must have moisture
content not greater than 25% (measured on a dry weight basis).
• Do not burn driftwood, treated, and painted wood or coloured paper as these
can corrode the wood fire and flue.
CAUTION: THE USE OF SOME TYPES OF PRESERVATIVE TREATED WOOD AS
FUEL CAN BE HAZARDOUS.
• Add fuel reasonably often. A large fuel load placed on a dying fire can drop
combustion temperatures undesirably.
• Avoid large smouldering fires. A small intense fire is more efficient.
• Move the heat control to high setting for a minute or so and turn off the air
circulating fan (if fitted) before opening the door on a low burning fire. This will clear
away any fumes in the firebox.
• Always open the door SLOWLY, and close and latch it shut securely again as soon
as possible after re-loading.
• When loading fuel, place the pieces of wood in a
Front-to-back direction to ensure good air access
and the cleanest possible burning. This will give
you the overall emission and room heating efficiency
that the fire was designed and tested to achieve.
(Except Atlanta Bay (NZ) model which was emission
tested with fuel loading from side to side)
• While loading fuel, take care in order to avoid damage to the insulating
boards, firebricks or top baffle.
• If smoke wafts into the room from a fully established fire while the door is open, first
check that make-up air can flow freely into the room to replace the air passing up
the flue. Make-up air is the replacement air used by fire for combustion which needs
to come into the room from external sources (See box below).
• Then check that the flue is not obstructed in any way, particularly by the rain cap
being too close to the end of the flue. Check flue is sealed correctly. (See the flue
cleaning requirements in the Maintenance section, page 11). If these checks do not
uncover the fault, you may need to add an extra length of flue and casings (bracing it,
if necessary) to counteract the down draught effects caused by roof shape, nearby
buildings, hills or trees. Consult experienced wood fire installer for solutions.
• Switch off the circulating fan (if fitted) when the fire is burning at low heat outputs.
This does not apply to LE4000 Provincial insert as it is permanently connected to
main power supply and has thermo-switch
• After a season, adjust the door to eliminate any minor leakage. (See MAINTENANCE
– Adjusting the Door Latch section on page 9).
REMEMBER, FOR THE FIRE TO DRAW PROPERLY, AIR MUST BE ABLE TO ENTER THE ROOM
WHERE YOUR WOODFIRE IS INSTALLED. YOU MAY HAVE TO LEAVE A DOOR SLIGHTLY OPEN
AND PERHAPS A WINDOW ELSEWHERE IN THE HOUSE IF YOUR HOME IS OF MODERN
AIRTIGHT CONSTRUCTION. THIS IS PARTICULARLY IMPORTANT IF AN AIR EXTRACTIO N FAN
IS OPERATIN G SOMEWHERE I N THE HOU SE. LEAVING THE ROOM DOOR OPEN WILL
HELP SPREAD WARMTH THROUGH THE REST OF YOUR HOME.
