BURNING GUIDELINES
OPACITY: This is the measure of how cleanly your
stove is burning. Opacity is measured in percent;
100% opacity is when an object is totally obscured
by the smoke column from a chimney, and 0% opac-
ity means that no smoke column can be seen. As
you become familiar with your stove, you should pe-
riodically check the opacity of the smoke column
emitted from your chimney. This will allow you to know
how to burn your stove as nearly smoke-free as pos-
sible (aim for a goal of 0% opacity).
BURN RATES
HIGH: Open (push in) both controls fully. It is impor-
tant to do this when reloading the stove. Failure to do
this could result in excessive emissions (opacity).
MEDIUM: After a wood load has been burning on
high for at least 15 minutes (longer for very large
pieces or wet wood), close (pull out) the primary con-
trol (on the right side of the stove). Leave the second-
ary control (under the ash catcher) open (pushed in).
LOW: After a wood load has been burning on high for
at least 15 minutes (longer for very large pieces or
wet wood), close (pull out) the primary control. Then
close down the secondary control, gradually making
sure to maintain flames in the stove. It is very important
to maintain flames in your stove during the first few
hours of a low burn, to avoid excessive air pollution.
OPERATING TIPS
Here are a few tips on operating your stove to obtain
maximum efficiency with lowest emissions:
1. Regardless of desired heat output, when loading
stove, burn your stove with both air controls wide
open for a minimum of 15 minutes.
2. Regulate burn rate (heat output) by using the
secondary control (center, under ash catcher).
The primary control (on the right) is mainly for
initial start-up, reloading, or high burns.
3. Heat output settings: Following 15 minutes of
burning with controls wide open (see #1 above):
BTU/Hr. Primary Secondary
Below 10,000 Closed after 5 min. Pull to stop
10,000-15,000 Closed after 5 min. ¾” - 1” open
15,000-30,000 Closed after 5 min. 1” - 2½” open
Maximum heat Full open Full open
These are approximate settings, and will vary with
type of wood or chimney draft.
4. Burn dry, well-seasoned wood (see Wood Se-
lection and Storage).
