DO NOT BURN WET COAL

The purpose of having the off delay timer on the distribution blower is to exhaust the excess heat in 

the stove that is inherent after the combustion blower and coal feeder turn off.  For this reason, it is not 

recommended that a 0 time setting be used. This will minimize any possibility of overheating the stove.

The other timer, which begins when the stoker control first takes control, is the "off" timer. This function 

of the stoker control is adjustable from 0 minutes to 15 minutes. Programming this timer with a value lets 

the stoker timer know how long to keep the combustion blower and the coal feeder turned off between 

maintenance cycles.

 Once the off timer has finished timing and the room temperature has not fallen below the thermostat 

set point, the "on" timer function will begin.  The programmable range for this function is also 0 minutes 

to 15 minutes. Once the "on" timer has started, all output (combustion blower, distribution blower, coal 

feeder) receptacles will become active for the programmed amount of time. When the "on" timer has 

finished timing, the stoker control will recycle and the "distribution blower" timer along with the "off" timer 

will once again become active.

  The  final  operator  interface  is  the  switch  on  the 

front  panel  adjacent  to  the  receptacles. This  switch 

in the "on" position allows power to the coal feeder 

motor receptacle.  In the "off" position, power will be 

removed only from the coal feeder motor receptacle.  

This switch in the "off" position, will stop the coal from 

moving across the grates and allow for easy lighting 

of the fire. Once the fire has been established move 

the switch to the "on" position.

how to Operate the Stoker Control

There are four operator interfaces on the stoker control. 

The operator interfaces are one rocker switch and three, 

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 verified by a small red light above 

the coal feeder receptacle being on when the switch 

is on. If the stove needs to be shut down, simply place 

the rocker switch in the "off" position. The small light 

above the coal feeder receptacle will turn off.

  The  other  three  switches  are  the  customer's  

adjustments for the timers (on time, 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 timers to 0.

 The "on" time and the "off" time should be programmed 

to a minimum time that keeps the coal burning during 

the maintenance cycling mode. The distribution blower 

time should be programmed for a time which is long enough to move the excess heat from the stove to 

the room heated. If this time is programmed for a longer time than the "off" time, the distribution blower 

will operate continuously. This will have no damaging effect on the stoker control.

 Recommended timer settings to start are, "on" 4 minutes, "off" 12 minutes, extend timer 2 minutes. 

You may find that these settings produce too much heat in pilot mode. If so, you can reduce the "on" 

time and increase the "off" time. However, be aware that you can go too far and have the fire go out. It 

is best to make  adjustments one minute at a time.
