Maintenance; Wood Insert; Glass Door - Osburn CW2100 Owner's Manual

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.
3.8.6 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 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.

4. 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 « Exploded diagram
and parts list » in the Wood Insert Installation and Operation Manual).
To avoid premature deterioration, follow the lighting and reloading procedures in section
« 3. Burning Wood Efficiently » and also avoid letting the heater run with the air intake fully open
for entire burn cycles.

Wood Insert

4.1.1 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 see « Exploded diagram
and parts list » in the Wood Insert Installation and Operation Manual. 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.
4.1.2 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.
4.2

Glass Door

4.2.1 Cleaning
Under normal conditions, the door glass should stay relatively clear. If the firewood is dry enough
and the operating instructions in this guide 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.
When the insert runs at a low combustion rate, light brown stains may form, especially in the lower
corners of the glass. This indicates that the fire has been smoky and some of the smoke has condensed
on the glass. It also indicates incomplete combustion of the wood, which also means more smoke
emissions and faster formation of creosote in the chimney.
