The Metro Ultra Insert is the world’s first conventional Insert wood fire
that meets the specification of ECan’s Ultra Low Emission standards and
discharges incredibly low emission particulate even during the ignition light
up phase.
You can greatly assist in minimising emission discharge by following the
guide below on how to help reduce emission while also helping yourself
with this ideal lighting technique. This ‘upside-down method’ is particularly
time saving to light as two minutes after ignition the door can be fully closed
while the fire generates a good ember bed without constant ongoing effort
of loading fuel to establish the ember bed. The less time the fire door is
opened, the quicker the fire heats and forms an ember bed of hot coals to
enable the addition of further fuel. Fuel positioning is predominantly in a
front to back orientation to promote air flow within the combustion chamber.
The specified emission results were achieved by following the described
method below using dry fuel with less than 25% moisture content.
Cold start with air control fully open:
• Place 3 to 4 medium pieces of wood as shown (total weight 1.2kg)
• Cross stack kindling on top of the lower stack (kindling weight 1kg)
• Place fire lighters, one each side of the load near the top
• Light the fire lighters and partially close the door, resting the door
spindle on the latch
• After 2 minutes with the kindling well alight, fully close the door.
Intermediate load with air control fully open:
• Approximately 40 minutes after lighting, once remaining fuel has
formed hot coals that crumble on reload, place the intermediate load
of firewood
• Place 3 to 4 pieces (approximately 1.2kg) across the ember bed
as shown. Maintain gaps between each piece but if one layer is too
condensed, cross stack a piece on top.
Main loads:
• Approximately 40 minutes after last loading, once remaining fuel has
formed hot coals that crumble on reload place your normal sized
firewood (Approximately 2kg). Once the fire is well established, regulate
the air control to achieve the desired burn rate and heat output. As you
move the air control to the right, firebox temperature and heat output
will increase, if you move the control to the left they will decrease
• Always open the air control fully prior to opening the door, then open
the door slowly. Every time you refuel, leave the air control on ‘high’ to
re-establish the fire
• When loading logs, place them end-on, ‘front to back’; air spaces
should be left between the logs to enable oxygen to get to as much of
the surface of the fuel as possible
• Never use the door to force wood into the firebox, as this is likely to
break the glass.
Reloading:
When reloading, always ensure firewood is placed onto an established
ember bed. If the ember bed is low, open the air control to maximum and
load smaller timber pieces to re-establish the ember bed.
