REFUELING THE BOILER
CAUTION
∙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.
Adjusting the Flue Gas Damper
To
Reloading Wood
CAUTION
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 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.
Draft Regulator
The draft regulator should be adjusted as follows:
It may take several trials adjusting the Samson control setting to maintain the proper boiler temperature during wood firing of approximately
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.
3.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.
CAUTION
Empty the ashes before they touch the grates so they will not interfere with the airflow to the vertical flue
passages
