Had a small standard wood stove for several years ("vermont casting" for 5 then a "century heat" for about 18). they were VERY simple and had no issues (occasional ooops on my part and smoked up the house). So i have retired the wood stove and installed a used king pellet kp130. reviews say they are a hit/miss kinda stove. so far, i can't say anything bad, however......

my questions : is there a way to even tell it is working like it should ?
it's set on Hr-2, takes 5-6 min to light. once going, i get a good flame, then it will cycle with too much air then back to "normal flame".
i have yet to notice or be able to tell any changes in any of the settings. (fans seem to have one speed).
hard to measure pellet consumption rate.

This is normal for a King stove, I think the control board is programed to do this to check/test that there is vacuum and the vacuum switch is working on each startup.

Not sure what you mean "any changes" are you just talking fan speed or do you mean flame height and heat output. There are some things you could check.

1. Check room fan speed on control board it should go either from 1-5 or 1-9 and then Rf-A which stands for room fan automatic. In Rf-A the fan speed will be automatically one speed above the heat setting. If you manually change the fan speed it will not allow you to go below one level greater then the heat setting. I have a hard time telling if fan changes going from 5 to 9 but if I set stove on 1 I can tell the difference from speeds 2 to 9. If your stove only goes from 1-5 the difference will be hard to hear.

2. You said this was a used stove, previous owner might have changed some internal settings, try doing the factory reset, Note: You might have to try several times as the buttons can be really touchy when trying to push both at same time. See post #3 below before resetting

FACTORY DEFAULTS
To return the control to its original factory default settings, press and hold the AUX UP and AUX DOWN buttons
together for three seconds.

The USSC control board can change many internal settings, see this video about feed rates.


3. If you meant no change even in the heat output. Do you have a external thermostat hooked up if No then you might check that the previous owner has not removed the thermostat jumper wire. If the jumper wire is removed and no thermostat is hooked up the stove will only run in idle mode no matter what you set the heat setting at. See pic for location on your control board.

kp130 and king 5002m are basically same stove you might want to write down all the current feed/draft settings before you change any thing or factory reset so you can reset them to current levels.

5500M C Codes
To adjust the operation constants, press the hold the MODE and AUGER DELAY buttons simultaneously
for 3 seconds. The display will show “C-1”. Use the HEAT RANGE UP or HEAT RANGE DOWN buttons to
change the constant number (see the list of vales below). When the desired constant is displayed, press
the ON button to toggle between viewing and editing the value. While editing a parameter, use the AUX
again to return to the constant number list. Press the OFF button to exit the operational constants
mode.
C1- Reset to defaults (hold Mode and Auger Delay buttons for 3 seconds to reset all to defaults).
C2- Fuel Lbs. per Hour HR 1 (0-5.0) – This is the fuel rate in pounds per hour for a heat range
setting of 1. The default is 1.75 lbs.
C3- Fuel lbs. per Hour HR 9 (0-5.0) – This is the fuel rate in pounds per hour for a heat range
setting of 5. The default is 4.5lbs. The fuel rates used between setting 1 and 5 are linearly
interpolated between these two settings.
C4- Draft Fan Level HR 1 (0-500) – This is the draft fan output level for a draft fan setting of 9.
The default is 150
C5- Draft Fan Level HR 9 (0-500) – This is the draft fan output level for a draft fan setting of 9.
The default is 350. See next parameter for disbursement.
C6- Monitor Hopper Switch (0-1) – If this parameter is set to 0 (default), the hopper switch input
is ignored. If it is set to 1, the hopper input is monitored, and if the hopper is opened, the auger
will stop. The delay LED will flash when the hopper is opened.
C7- Ramp Seconds for increasing level (0-300) – When the heat range setting is adjusted, control
will ramp from the current setting to the target setting to avoid abrupt changes in the outputs
that could cause problems with the flame quality. The ramp seconds value sets the amount of
time to spend on each heat range setting (1-9 pseudo ranges not 1-3 user ranges) as the current
setting is ramping toward the target. If the current setting is ramping down toward a lower
target, the ramp value is half this number. The default value is 90 seconds.
C8- Startup Minutes for detecting Warm Stove – (10-60) this is the amount of time the control
will wait for the stove to reach the warm temperature (110 Degrees F) after the stove has been
started before shutting down and reporting an Error condition Err3. The default is 30minutes.
C9- Over temp Set point – (0-500) this is the temperature the flue gas can reach before an over
temp condition exists. If the measured temperature is higher than this set point, the control will
stop auguring fuel until the temperature returns to a safe operating point. The default is 445
degrees.
C10- Cutback Set point – This is the temperature that the flue gas can reach before a cutback
condition exists. If the measured temperature is higher than this set point, the control ramps
down the heat range according to the auger ramp seconds value. The default is 430 degrees.
C11- Room fan on set point – (0-300) this is the temperature that the measured flue gas must
reach before the room fan turns on. This variable also serves to indicate to the control that the
stove is warm. If the measured temperature is higher than this set point, the stove is considered
warm and will not create an Er3. Whether or not the stove is warm also determines if the unit
will recover from a power failure. If the stove is warm when the power is lost and cold when it
returns, it will shut down with an Er4 error. The default is 130 degrees.
C12- Cold stove set point – (0-300) this variable is used to determine when the stove is cold and
ready to be shut down. If during the shutdown sequence the measured temperature is less than
this value, the stove will stop running the fans to cool it off. The default is 110 degrees.
C13- Room fan level HR 9 (0-500) – this is the output level applied to the room fan for a setting o
1. The default values is 300/500.
C14- Room fan level HR 9 (0-500) – This is the output level applied to the room fan for a setting
of 9. The default value is 500/500. The room fan output levels used between settings 1 and 9 are
linearly interpolated between these two settings.
C15- Auger load time (0-30) – This variable is used to control the length of time that the fuel is
augured into the burn pot during startup. The default is 6 minutes.
C16- Starter on time (0-30) – This variable is used to control the length of time that the igniter is
turned on during startup. The default is 8 minutes.
C17- Ignore fuse errors (0-1) – This variable can be used to ignore errors detected by open fuses.
By default, it is o (do not ignore the vacuum switch), but can be set to 1 for diagnostic of
emergency operation purpose.
C18- Ignore vacuum switch (0-1) – This variable can be used to ignore the vacuum switch. By
default it 0 (do not ignore the vacuum switch), but can be set to 1 for diagnostic or emergency
operation purposes.
C19- Bump rate in pounds per hour (0-0.5) – The bump rate defines the rate of fuel to be
delivered when the unit is over temperature or in shutdown to prevent burn back, Since this
stove design isn’t conductive to burn back, the default setting is 0lbs. per hour, but can be
adjusted to a maximum of 0.5lbs per hour.
C20- Purge time (0-120) – The purge time defines how many seconds to run the auger to purge
it on power down or shutdown as the stove moves from a warm state to a cool state. It is
intended to push and partially heated pellets still in the auger tube out. By default, the auger
will run for 30 seconds, but can be set between 0 and 120.
C21- Enable serial communication (0-10 – By default, serial communication is not enabled (0).
Set this variable to 1 to enable communication.

This is normal for a King stove, I think the control board is programed to do this to check/test that there is vacuum and the vacuum switch is working on each startup.

*** i need to clarify.... it will cycle like this during operation. so every few minutes (10 min +/-)

Not sure what you mean "any changes" are you just talking fan speed or do you mean flame height and heat output. There are some things you could check.

1. Check room fan speed on control board it should go either from 1-5 or 1-9 and then Rf-A which stands for room fan automatic. In Rf-A the fan speed will be automatically one speed above the heat setting. If you manually change the fan speed it will not allow you to go below one level greater then the heat setting. I have a hard time telling if fan changes going from 5 to 9 but if I set stove on 1 I can tell the difference from speeds 2 to 9. If your stove only goes from 1-5 the difference will be hard to hear.

2. You said this was a used stove, previous owner might have changed some internal settings, try doing the factory reset, Note: You might have to try several times as the buttons can be really touchy when trying to push both at same time. See post #3 below before resetting

*** better description.... i can not hear a difference in fan speed.

*** pellet consumption seems to be excessive (appears to be around 3+ gallons in a 4hr period?)




FACTORY DEFAULTS
To return the control to its original factory default settings, press and hold the AUX UP and AUX DOWN buttons
together for three seconds.

The USSC control board can change many internal settings, see this video about feed rates.


3. If you meant no change even in the heat output. Do you have a external thermostat hooked up if No then you might check that the previous owner has not removed the thermostat jumper wire. If the jumper wire is removed and no thermostat is hooked up the stove will only run in idle mode no matter what you set the heat setting at. See pic for location on your control board.
*** there is no thermostat or remote involved. only has 5 settings (H1 to H5)

i WILL be going over the jumpers and review/study those feed rates/settings.
