The top receptacle (0.5 A) provides power to the coal
feeder motor. Thus, the plug from the coal feeder motor
should be inserted into this receptacle.
The center receptacle (0.75 A) provides power for the
combustion blower motor. Thus, the plug from the com-
bustion blower should be inserted into this receptacle.
The bottom receptacle (1.25 A) is not used.
The thermostat connections on the back panel of the
stoker control are .25 inch male quick connect terminals.
The mating connectors (supplied) should be .25 inch
female quick connector terminals. The wire should be
no smaller than 22 gauge.
The thermostat connections should be connected to
the aquastat as shown on the wiring diagram.
The AC power cord should be the last connection made.
The power cord should be plugged into a 115 VAC / 60
hertz wall outlet, which has proper grounding available.
This 115 AC volt wall outlet should also be capable of
handling 3 amps of current because this is the maximum
amperage this unit will draw.
There are four operator interfaces on the Stoker Con-
trol. The operator interfaces are: one (1) rocker switch
and three (3) 16-position rotary switches.
The rocker switch is a power switch that controls only
the coal feeder motor. For normal operation this switch
should be placed in the “on” position. This switch’s
operation can be veried by a small red light above the
coal feeder receptacle being on when the switch is on.
The off position is used for lighting the re.
The other three switches are the customer’s adjust-
ments for the timers (on timer, off time, distribution
blower time). These switches can adjust each timer
individually from 1 minute to 15 minutes in 1 minute
increments. Do not set pilot mode timers to 0.
The “on” time and the “off’ time should be pro-
grammed to a minimum time that keeps the coal
burning during the maintenance cycling mode. The
distribution blower time should be set to 0. This is be-
cause the VF 3000 doesn’t have a distribution blower.
The Verti-Flow™ Stoker Control is also used on the
Magnum Stoker which does use this timer.
Recommended timer settings to start are: “on” 4
minutes, “off” 12 minutes, extend timer 0 minutes.
You may nd that these settings produce too much
heat in pilot mode. If so, you can reduce the “on”
time and increase the “off” time. However, we do not
recommend going below 4 minutes with the on time
for efciency reasons.
