OF 40)
This kind of fire is good for mild weather and should provide enough heat for up to four hours.
Small fires like this are a good time to use softer wood species and avoid overheating the house.
5.7.2 Low and Long Output Fires
For a fire that will last up to eight hours but will not produce intense heat, use soft wood and
place the logs compactly in the firebox. Before reducing the air intake, the load will have to burn
at full heat for long enough for charring the surface of the logs. The flame must be bright before
letting the fire burn by itself.
5.7.3 High Output Fires
When heating needs are high during cold weather, the fire should burn steadily and brightly. This
is the time to use larger pieces of hardwood. Place 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
combustion this fireplace is capable of. Special attention must be paid when building fires like
this since if the air intake is reduced too quickly, the fire could smoulder. The wood must be
flaming brightly before leaving the fire to burn.
5.7.4 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 increases 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. To avoid premature
deterioration, follow the lighting and reloading procedures in section «5. Burning Wood Efficiently»
and also avoid letting the heater run with the air intake fully open for entire burn cycles.

Fireplace

6.1.1 Refractory Material and Baffle
Inspect the firebricks or the refractory panels and the baffle for damage periodically and replace
anything that is cracked or broken.
Operation of the heater with a cracked or missing baffle may cause unsafe temperatures and
hazardous conditions and will void the warranty.
6.2

Glass Door

6.2.1 Cleaning
Under normal conditions, the door glass should stay relatively clear. If the firewood is dry
enough and the operating instructions in this manual are followed, a whitish, dusty deposit will
form on the inner surface of the glass after a week or so of use. This is normal and can be easily
removed when the heater is cold by wiping with a damp cloth or paper towel and then drying.
