Particle Fuel Delivery Option
Before beginning to burn sawdust, shavings,
wood chips, or other wood waste, it is important to
rst create a bed of charcoal in the Wood Gun™
rebox to prevent these small fuel particles from
being drawn unburned through the unit by the dra9-
inducing fan. Begin by turning on the main switch.
Start the re using kindling and newspaper in the
same manner as described in the previous section.
Once the kindling is going, add some larger chunk or
log wood. Be careful not to shi9 the diverter bricks
while loading the wood. Close the load door.
Allow this fuel charge to burn down and heat the
refractory. When this occurs, ensure mode switches
are in Auto, and then turn the feed system on to
begin lling the rebox with particle fuel. A9er the
unit is at operating temperature, secondary air may
be activated as needed (if the boiler is so equipped).
If the re must be restarted a9er a long dormant
period (aside from normal on/o: cycling), you must
remove any unspent particle fuel from the rebox by
hand and start the re again from the beginning. If
you try to add particle fuel before the refractory
combustion chambers are hot, glowing particles may
be discharged out of the stack. Sometimes, it is
possible that the refractory mass is still above the
ignition point of wood (usually within 4-6 hours of
last on-cycle). If this is the case, the fuel may re-
ignite automatically as with normal on/o: cycling.
ADJUSTMENT OF THE DRAFT-INDUCING
FAN (BELT-DRIVE ONLY)
e rate of burn (BTU output) for a given type of
fuel is essentially determined by the amount of air
drawn through the unit by the dra9-inducing fan.
e fan drive assembly on all large Wood Gun
Models (and smaller Wood Guns with the belt drive
option) has one or two variable sheave pulleys,
which can be adjusted to change the speed of the fan.
When the unit is assembled and tested at the factory
an arbitrary se7ing is made to check for vibration.
e nal se7ing can only be made once a sample of
the fuel to be burned is available. In addition to
manipulating fan speed by swapping sheaves,
Alternate Heating Systems also o:ers a VFD
(Variable Frequency Drive) option for the induction
fan motor.
Dry fuel and material having a high glue content
will require less air (CFM) to achieve rated output
than will fuel of higher moisture. High-energy fuel
can easily produce output higher than the BTU
rating listed in the product literature. If the unit is
operated continuously at higher than rated output,
the life of the refractory will be shortened. It does
not harm the Wood Gun to operate continuously at
rated output. Selecting a burning rate that closely
approximates the heating load will improve
refractory life when compared to operating above
rated output.
OPTIONAL AUTOMATIC FUEL DELIVERY
SYSTEMS
Automatic particle fuel feeding systems are
available for all Wood Gun™ models that are factory
equipped with a top fuel feed tube. An auger delivers
the fuel to the top of the fuel chamber where it drops
through a fuel tube to form a conical shaped pile. A
patented fuel level control system comprised of
several electrical control devices and a photoelectric
eye monitors the level of the pile. As fuel is burned
and the level drops, the auger is activated to
replenish the fuel chamber.

Note: Self Re-ignition time is dependent primarily
on two variables (1) how hot the refractory is at
shutdown (2) how big your refractory size (boiler
size).
Note: When starting a fire in a Wood Gun™
equipped with an oil or gas burner, it is first
necessary to switch the fuel selector control to
“wood” mode.
