Operating Hints - Masport HORIZON Owner's Manual & Installation Manual

When the kindling is well alight, open the door slowly and add some larger pieces of wood.
throw fuel pieces into the firebox as this could damage the top baffle and the insulating
boards or firebricks.
Close and latch the door firmly.
Move the heat output control away from the maximum position only after the fire is well established.
A new woodfire should not be run at higher than half setting beyond the first 30 minutes until it has
been used for a total of 8 hours. Once fully 'run in', we recommend running at full heat for up to one
hour after lighting as this will minimise creosote build-up in the flue. The control can then be set
wherever desired.
The special high temperature paint on the firebox will emit some smoke as it cures during the first few
minutes of running. This is quite normal.

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. If moist fuel must be
used, add it only to a really hot fire, mixing it with a large proportion of dry fuel. In Clean Air Zones,
only wood may be used as fuel, and it must have a moisture content not greater than 25% (measured
on a wet weight basis).
• Do not burn driftwood, as salt will corrode the woodfire.
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 maximum 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. In the Christchurch Clean Air Zone, load the fuel from side to side
in the LE 3000 model. Wood pieces for the Provincial Clean Air Zone (Christchurch) model should
be generally about 250mm long, and should not exceed 300mm in length.
• Load fuel carefully to avoid damage to the insulating boards, firebricks or top baffle.
• If smoke wafts into the room 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. (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. If these
checks do not uncover the fault, add an extra length of flue (bracing it, if necessary) to counteract the
down draught effects caused by roof shape, nearby buildings, hills or trees.
• Switch off the circulating fan (if fitted) when the fire is burning at low heat outputs. Use only the
slow fan speed at medium heat output, moving to the higher speed(s) only when full heat output has
been reached.
• Adjust the door to eliminate any minor leakage. (See MAINTENANCE - page 15). Serious leakage
will require a new door seal.
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. LEAVING THE ROOM DOOR OPEN WILL
HELP SPREAD WARMTH THROUGH THE REST OF YOUR HOME.
