1.4 EPA Loading
For EPA Certification testing, wood logs were 16 ± 1 inches long and the specie used was
beech.
1.4.1 Air control
The air control is located underneath the ash shelf.
To open the air control, push the air control handle
completely to the left (High). This will increase the
burn rate. To close the air control, push the air control
handle completely to the right (Low). This will decrease
the burn rate.
1.4.2 High burn rate
Open the air control completely. Place eight small
pieces (2"x2") of wood in the firebox crossing
them at the greatest possible angle. Criss cross
15 kindling wood pieces on the small pieces
of wood in three to four layers at the greatest possible angle. Tie knot with five sheets of paper
and place them on top of the kindling wood. Light up the paper and let the door ajar at 90° until
all the kindling wood is on fire. Close the door. When there is no more fire in the front of the
firebox and there are only faint flames on the wood in the back of the firebox, break ashes, level
the coal bed and put six logs in the firebox of approximatively 4"x4" or 3"x3". Add the load in an
East-West configuration divided in 3 columns: 2 smallest logs in the back, 2 logs in the middle
and 2 logs in the front. Leave one inch of air space between the rear bricks and the first column,
another one inch between the first two columns, and finally leave no space between the second
and the third column. Let the door ajar to leave a space of one inch on the door handle’s side
for 3 minutes and then close the door.
1.4.3 Medium and low burn rate
On a 2" coal bed that is still slightly red, place six logs of approximatively 4"x4" or 5"x5" Add the
load in an East-West configuration divided in 3 columns: 2 logs in the back, 2 logs in the middle
and 2 logs in the front. The distance between the logs and the rear brick shall be approximately
1 inch. There should be one inch of air space between all the columns. Let the door ajar at 90°
for approximately 6 min. Then, close the door with the primary air control open. Leave to burn
with the primary air control open for approximately 5 more minutes, then close the primary air
control halfway. After another 5 minutes, close the primary air control completely for the low
burn rate and leave it halfway for the medium burn rate.
