2.21 EPA Certification Loading
For EPA Certification testing, wood logs were 16 ± 1 inches long and the specie used was hard
maple.
2.21.1 Air Control
The air control is located underneath the ash shelf.
To open the air control, pull the air control handle
completely (High). This will increase the burn rate.
To close the air control, push the air control handle
completely (Low). This will decrease the burn rate.
2.21.2 High burn rate
Open the air control completely. Place six small pieces
(2" x 2") of wood in the firebox crossing them at the
greatest possible angle. Criss cross fifteen kindling
wood pieces on the small pieces of wood in three
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 and the first row of
small pieces of wood is on fire too. 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 five logs in the firebox. Place the biggest log (about 4"x 4") at the back in
an East-West orientation. Place a medium log (about 3"x 3") on top of the biggest one. Place
another medium on coal bed on front of the biggest with another medium on top of it. Place
the last medium one in front. If you need to stack the last piece over the ash lip, make sure
you always leave at least 1 5/8 inch between the last log and the inner wall of the combustion
chamber. There should be air space between each log and between the logs and the bricks. Let
the door ajar at 90° for approximately two minutes and then close the door.
2.21.3 Medium and low burn rate
On a 2" coal bed that is still slightly red, place five logs of approximatively 4"x 4" or 3"x 3" with
an East- West orientation. Place a medium log at the back. Place the biggest log in the center
with a medium one on top of it. Place a medium on the front and another medium on top of it.
If you need to stack the front pieces over the ash lip, make sure you always leave at least 1
5/8 inch between the last log and the inner wall of the combustion chamber. There should be
air space between each log and between the logs and the bricks. Let the door ajar at 90° for
approximately 5 min. Then, close the door with the primary air control open. Leave to burn with
the primary air control open for approximately 10 minutes and then close the primary air control
completely for the low burn rate and halfway for the medium burn rate.
