Operation

8.Turn the MIN. TEMP. Dial on the control board to the desired Minimum temperature. This will start the lighting process if the temperature at the aquastat sensor is approximately 5° F. less than the set temperature on the MAX TEMP. dial.

This is more than just an automatic ignition pellet boiler. The automatic system will allow the fire size to be adjusted to match the heating needs and even put the fire out if necessary. If heat is needed after the fire is out, the boiler will automatically re-ignite and adjust the fire size to match the heating need.

9.Fill hopper with pellets and remove ashes as required.

Type of Fuel

Use pelletized wood only. The lower the ash content of the pellets the less cleaning that will be needed of the heat exchanger surfaces. The cleaner these surfaces are kept, the more efficient the boiler will be.

NOTE: Do not burn garbage, gasoline, naphtha, engine oil, or other inappropriate materials in this unit. Store pellets in the manufacturer’s wrapping until needed to prevent pellets from absorbing moisture. Do not store fuel within the appliance installation clearances, or within the space required for fueling, ash removal, and other routine maintenance operations.

Lighting A Fire Manually

Lighting the fire manually will not be necessary unless the igniter system fails.

Follow steps 1 through 5 of the instructions for automatic lighting.

6.Flip the Igniter Switch Down into the “MANUAL- LIGHT” position. See Fig. 12.

9. Have matches or other ignition source ready.

10. Turn Mode Selector to desired MIN TEMP setting. This will start the combustion blower and allow the ESP to control the fire in relation to the MAX TEMP Dial setting. (The MAX TEMP dial setting must always be set above the MIN TEMP setting) Once the fire is well established the MAX TEMP dial can remain on

any temperature setting desired.

NOTE: When the Switch is set to Manual ignite position the boiler will function as in auto ignite except the fire will not be allowed to go out. It will only be allowed to go to a minimum burn rate between the times the aquastat is calling for heat. This rate is about 1.1 pound of fuel per hour. If used in the Manual ignite mode, be sure there is an overheat dump zone in place. Note that if the dump zone does not provide sufficient cooling, and the water temperature continues rising, the feed motor will be forced to shut off. Because the unit is in Manual Ignite mode, it will not re-ignite when the water temperature cools below the control settings.
