7.4 FUEL

WARNING

DO NOT STORE FUEL WITHIN THE CLEARANCE TO COMBUSTIBLES, OR IN THE SPACE REQUIRED

FOR RE-FUELING AND ASH REMOVAL.

BURNING WET, UNSEASONED WOOD CAN CAUSE EXCESSIVE CREOSOTE ACCUMULATION. WHEN

IGNITED IT CAN CAUSE A CHIMNEY FIRE THAT MAY RESULT IN A SERIOUS HOUSE FIRE.

Maximum heat for minimum fuel (optimum burn) occurs when the appliance top temperature is between 500°F

(260°C) and 600°F (315°C). The bricks will be nearly all white and the glass mostly clear. The whiteness of the

bricks and the cleanliness of the glass are good indicators of your operating efﬁ ciency. Not enough heat is

produced when only one or two pieces of wood are burned or the wood may not burn completely. A minimum

of three pieces are needed to encase a bed of coals that sustains the ﬁ re.

Loosely stacked wood burns quicker than a tightly packed load. Wood burns in cycles rather than giving a

steady output of heat. It is best to plan these cycles around your household routine so that only enough coals

are left to start the next load. In the evening, load your appliance, at least, a half-hour before bed to ensure a

good ﬁ re, hot enough to close the draft control for an overnight burn.

Burn only dry seasoned wood with 20% moisture content. It produces more heat and less soot or creosote.

Do not burn ocean beach wood. Its salt content can produce a metal eating acid. When refueling open the

door slowly to prevent smoke spillage. Use a pair of long gloves (barbecue gloves) when feeding the ﬁ re.

Because these appliances burn from the front to back, they are clean and efﬁ cient, but they are also very hot

and gloves are useful. Keep a small steel shovel nearby to use as a poker and to remove ashes. Do not store

the wood within 3 feet (1m) of the appliance.

93.1

A ﬂ ash ﬁ re is a small ﬁ re burned quickly when you don't need much

heat. After your kindling has "caught", load at least 3 pieces of wood,

stacked loosely. Burn with the draft control fully open or closed only

slightly.

7.5 LIGHTING A FIRE

7.5.1 FLASH FIRE

7.5.2 EXTENDED FIRE

82.1

Load your larger pieces of wood so they are tightly packed, close enough to prevent the ﬂ ames from

penetrating it completely. After approximately 30 minutes, depending on the size of the load, close the draft

control completely making sure that the ﬁ re is not extinguished.

DO NOT OVERFIRE THE APPLIANCE!

Overﬁ ring can occur by:

A. Burning large amounts of smaller wood pieces such as furniture scraps, skids or treated wood;

B. Vigorously burning large loads of wood with the draft control on “HIGH” (fully open) for long periods of

time (one or two hours).

C. Operating the appliance with the ash dump door blocked open or a poor gasket seal on the main door.
