Destination 2.3 Insert Installation and Operation Manual
If the flames diminish to the point of
disappearing, the air intake has been
reduced too early in the combustion cycle
or the wood used is too wet. If the wood
is dry and the air control is used properly,
the flames should decrease, but remain
bright and stable.
5.4 Fires Types
Using the air intake control is not the only way to match the insert heat output to the desired
temperature in the house. A house will need far less heating in October than in January to maintain
a comfortable temperature. Filling the firebox full in fall weather will overheat the space. Otherwise,
the combustion rate will have to be reduced to a minimum and the fire will be smoky and inefficient.
Here are some suggestions for building fires suitable for different heating needs.
5.4.1 Small Fires to Take the Chill Off the House
To build a small fire that will produce a low heat output, use small pieces of firewood and load them
crisscross in the firebox. The pieces should be only 3" to 4" in diameter. After raking the coals, you
can lay two pieces parallel to each other corner to corner in the firebox and lay two more across
them in the other direction. Open the air control fully and only reduce the air after the wood is fully
flaming.
This kind of fire is good for mild weather when you are around to tend the insert and should provide
enough heat for four hours or more. Small fires like this are a good time to use softer wood species
so there will be less chance of overheating the house.
5.4.2 Long Lasting Low Output Fires
Sometimes you will want to build a fire to last up to eight hours, but don’t need intense heat. In this
case use soft wood species and place the logs compactly in the firebox so the pieces are packed
tightly together. You will need to fire the load hot for long enough to fully char the log surfaces before
you can turn the air down. Make sure the fire is flaming brightly before leaving the fire to burn.
5.4.3 High Output Fires for Cold Weather
When the heat demand is high during cold weather, you’ll need a fire that burns steadily and brightly.
This is the time to use larger pieces of hardwood fuel if you have it. Put the biggest pieces at the
back of the firebox and place the rest of the pieces compactly. A densely built fire like this will produce
the longest burn your insert is capable of.
You will need to be cautious when building fires like this because if the air is turned down too much,
the fire could smoulder. Make sure the wood is flaming brightly before leaving the fire to burn.
5.4.4 Maximum Burn Cycle Times
The burn cycle time is the period between loading wood on a coal bed and the consumption of that
wood back to a coal bed of the same size. The flaming phase of the fire lasts for roughly the first half
of the burn cycle and the second half is the coal bed phase during which there is little or no flame.
