The table below gives an approximate maximum burn cycle times, based on firebox volume.
A longer burning time is not necessarily an indication of efficient insert operation. It is preferable
to build a smaller fire that will provide three or four hours of heating than to fully load the firebox
for a much longer burn. Shorter burn cycles make it easier to match the heat output of the insert
to the heat demand for the space.

Logs Orientation
In a relatively square firebox, the wood can be loaded north-south (ends of the logs visible) or
east-west (sides of the logs visible).
North-south loads allow more wood to be loaded at the same time. On the other hand, they
break into smaller pieces faster. North-south loading is good for high output, long lasting fires
for cold weather.
East-west loads allow a limited amount of wood since too many logs could cause them to fall
on the glass. East-west loads, placed in a compact way, take a long time before breaking down.
They are excellent for low-intensity, long-lasting fires in relatively mild weather.
5.7.6
Carbon Monoxide
When there is no more flame in the firebox and there are still some unburned logs, check outside
if there is smoke coming out of the chimney. If this is the case, it means that the fire is out of
air to burn properly. In this situation, the level of CO increase and it is important to react. Open
the door slightly and move the logs with a poker. Create a passage for the air below by making
a trench with the ember bed. Add small pieces of wood to restart the combustion.

6. Maintenance

This heater will give many years of reliable service if used and maintained properly. Internal
components of the firebox such as firebricks or refractory panels, baffle and air tubes will wear
over time. Defective parts should always be replaced with original parts see

Cleaning and Painting

Painted and plated surfaces can be wiped down with a soft, damp cloth. If the paint is scratched
or damaged, it is possible to repaint the insert with a heat-resistant paint. Do not clean or
paint the insert when it is hot. Before painting, the surface should be sanded lightly with
sandpaper and then wiped off to remove dust. Apply two thin layers of paint.
