Use extreme caution when refueling the boiler. If the door is opened too quickly, the unburned hot gases

may ignite and cause a back puff. This is especially true with very dry wood.

•

DO NOT tamper with the chain on the draft regulator as it could cause the fire to burn out of control.

•

Keep ash and fuel doors closed if not refueling boiler.

•

DO NOT overload the boiler.

To Re-fire the boiler, open the flue gas damper to establish more draft through the combustion chamber. Af-

ter refueling, when the fire is established, it probably will be necessary to close the flue gas damper to match

the heating requirements and accommodate the chimney draft.

To reload wood in the firebox, Carefully open the top fire door an inch or so until you can see that the fire is

burning well and the smoke is exhausting up into the heat exchanger above the firebox. While loading, the door can

be left fully open and logs can be added by swinging the flue gas damper open. Logs should be 1" or 2" shorter than

the firebox in the boiler and should be of such diameter as not to "bridge" or jam in the firebox. Logs of 2" to 4" in

diameter should be used whenever possible. This will produce an even burning and efficient fire. Wood split to this

size also dries much more quickly. The logs should be stacked and lined up horizontally so the burning wood can

settle easily. Add the largest wood when the fire is burning well and some coals are forming. After you have filled

the firebox to the desired level, close the loading door securely. Damage or injury will result if wood is not loaded

carefully generally level with bottom of flue gas damper. If loaded in-correctly there is a risk of fire or injury.

In long- term maintenance of the boiler fire, frequent stoking with small amounts of wood is better than in-

frequent stoking with larger amounts. When you stoke the fire, pull some of the hot coals forward in the firebox

where they can get sufficient air to burn thereby enabling them to set fire to the next load of wood.

It may take several trials adjusting the Samson control setting to maintain the proper boiler temperature during

wood firing of approximately 180-190°F. The final control setting may be a little more or a little less then the red

80°C on the dial. During normal operation, especially in the spring or fall, it is necessary to allow air to enter

through the secondary air damper. This method reduces the possibility of creosote formation when the lower air flap

is fully closed.

1. Turn the black knob counterclockwise to set the red number from 40°C to 80°C at the red line.

2. Allow the wood fire to slowly bring the boiler temperature up to about 180°F on the temperature gauge.

As this temperature is reached, the lower door air inlet flap will begin to close because the proper combustion of

air has entered the firebox to maintain the selected boiler temperature.

DO NOT tamper with the chain on the draft regulator as it could cause the fire to burn out of control.

Empty the ashes before they touch the grates so they will not interfere with the airflow to the vertical flue
