OPENING AND CLOSING

FUEL FEED DOOR

FIRETENDING

Firetending is the occasional poking or stirring of the burning fuel bed to ensure airflow through the fire and adding new wood

as needed. With experience, you should determine how often fire tending is required to maintain the desired heat output of

the heater. To ensure safe and satisfactory performance of the heater, the following rules should be observed.

KEEP THE FEED DOOR AND ASH DOORS CLOSED EXCEPT WHEN TENDING THE FIRE OR REMOVING ASHES.

Operating the heater with the doors open can cause the heater to overheat and will increase the possibility of smoke,

ash or sparks escaping the heater and damaging the dwelling or its contents.

NEVER OPEN THE FEED DOOR WITHOUT FIRST TURNING THE THERMOSTAT TO ""HI" FOR AT LEAST 30

SECONDS.

ADD ONLY SMALL AMOUNTS OF FRESH WOOD TO THE HEATER AT EACH REFUELING. Adding large amounts

of fresh wood can cause an accumulation of gases above the fire that can cause backpuffing. Backpuffing can occur

whenever concentrated gasses accumulate over the fire bed and then catch fire quickly. This may cause smoke and

flame to be expelled from the heater during fire tending but under rare conditions, backpuffing can be severe enough to

break apart poorly connected chimney connector pipes. If backpuffing is experienced, see CORRECTION OF OPERA-

TIONAL PROBLEMS section of this manual. This is an abnormal condition and a potential hazard. Determine and

correct the cause.

TURN THERMOSTAT TO "HI" FOR 15 MINUTES AFTER ADDING FRESH WOOD TO A FIRE. This allows the gases

to be driven off and shortens the length of time the dense smoke is likely to deposit creosote on the chimney walls.

DO NOT TAMPER WITH THE INTERNAL THERMOSTAT MECHANISM. The thermostat has been designed and

calibrated to provide continuous control of the fire for safety and efficiency. Thermostat adjustments are made with the

thermostat control knob only. (See figure 9.)

PREPARE THE HEATER TO HOLD FIRE ALL NIGHT BY LOADING IT WITH WELL DRIED WOOD AT LEAST AN

HOUR BEFORE BEDTIME. Burn the heater at the normal rate for this hour, then turn it back to a slower burn just

before going to bed. This procedure will help drive excess moisture and gases out of wood and minimize creosote

buildup during the night. This procedure also minimizes the likelihood of backpuffing.

DO NOT OVERFIRE THE HEATER. If any part of the heater or chimney connector becomes red hot turn the thermo-

stat to low and keep the ash and feed doors closed until the heater cools.

The small amounts of wood used in daily fire tending should be kept in a noncombustible container at least 36 inches from

the heater.

Two wood characteristics largely determine the amount of heat energy per cord. The first is moisture content. Wood must

be dry before it will burn properly. When first cut, its moisture content is high so wood burns poorly and encourages the

formation of creosote. It should be cut and stored in a dry place several months, preferably a year before it is used.

Splitting the wood before it is stored reduces its drying time and exposing both ends to the air aids in drying. After wood

has been stored from six to twelve months, it will be dried to a moisture content of 15 to 25 percent. This drying results in

more even burning and will minimize the buildup of creosote in your chimney.
