3.5 Maintaining The Fire

Your Enerzone insert will work best if a thick bed of hot embers is maintained in the bottom of the
firebox, and a minimum of two large pieces of seasoned fuel are added. Combustion efficiency is
largely related to establishing a hot ember bed, and hot firebox temperatures. The quicker the insert
and fuel get up to operating temperature, the better. A small intense fire is preferred to a large
smouldering fire, both to improve combustion efficiency and to reduce the amount of creosote emitted.
The best performance will be achieved by adding relatively small amounts of fuel to a well established
ember bed, and then operating with the air inlet control open long enough to achieve a hot fire.
Cordwood should be placed with air in between individual pieces. Use a poker to make an air channel
in the embers below the wood, this will allow air to flow under the wood for a more efficient burn.
Extended burn times can be accomplished by first operating the insert on a full load with the air inlet
controls wide open. Once the fire is well established, and the moisture has been driven out of the
wood, reduce the air control to a lower setting. The unit should then burn cleanly without
smouldering. If the fire smoulders without flame, re-establish a hotter fire before moving the air
control to the lower setting. A yellow flame burning in the top of the firebox is a good indication of a
clean efficiently burning fire.
Refuelling technique is important for good performance. The best efficiency and performance from
your insert can be achieved by adding partial loads of fuel and allowing them to get up to operating
temperature before adding additional fuel. Adding a large amount of fuel at one time will increase the
time required to get the fuel up to its ignition temperature, and an extended time to reach optimal
performance. When refuelling, open the air control or hold the door partially open 1" (25 mm) or less,
long enough (less than 5 minutes) so that the fire has well established flames. When refuelling, care is
required to ensure that fuel or embers do not fall out of the door opening.
In order to achieve an optimum efficiency from your unit, we suggest that you operate it with the air
control slightly open (approximately 10%). Make sure that you have a good fire going and an
adequate ember bed before you completely close the air control. Closing the air control too soon will
lower combustion efficiency and may cause the fire to die out. The addition of a blower (if not already
included) is highly recommended to maximize your unit's efficiency.
