ASHBY-MF MAINTENANCE 

 
NOTE:  WHEN  YOU  FIRST  OPERATE  YOUR  MULTI-FUEL  INSERT,  CHECK  TO 
DETERMINE  THE  NEEDED  CLEANING  FREQUENCY.  THE  ASHBY  REQUIRES  A 
MINIMUM  AMOUNT  OF  DAILY  MAINTENANCE.  REQUIRED  MAINTENANCE 
DEPENDS LARGELY UPON THE QUALITY OF FUEL BURNED AND THE RATE OF 
BURN.  THE  AMOUNT  OF  DAILY  MAINTENANCE  WILL  INCREASE  IF  FUEL 
QUALITY DECREASES AND/OR THE BURNING RATE OF THE FUEL INCREASES. 
 
NOTE:  FAILURE  TO  KEEP  YOUR  INSERT  CLEAN,  AS  DESCRIBED  IN  THIS 
MANUAL,  COULD  RESULT  IN  POOR  OPERATION,  INEFFICIENT  FUEL  USAGE 
AND  A  POSSIBLE  SAFETY  HAZARD!  IT  IS  THE  RESPONSIBILITY  OF  THE 
OWNER/USER TO DETERMINE THE NEEDED MAINTENANCE FREQUENCY. 
 
CAUTION: THE DOOR AND FRONT PART OF THE MULTI-FUEL INSERT WILL BE 
HOT. DO NOT TOUCH ANY PART OF THE UNIT THAT IS HOT! 
 

Clinker/Ash Removal – Ashby-MF with the Multi-Fuel Pot 

 

Once a clinker/ash has formed in the burn pot, 

it must be removed

 or the unit will go out. The St. 

Croix Burn system is designed to remove the clinker/ash without loosing the fire in the burn pot.  
 
It is a 3-part system. 
 

1.

 

The coal rake. This is a “fork” shaped device that will allow the operator to “shave” the 
burning  coals  off  the  top  of  the  clinker,  separating  the  2  areas  of  the  burn  pot.  The 
burning fuel on top and the clinker on the bottom. The rod pivots to the right to allow it to 
fit behind the Lower Panel. 

 

2.

 

The slide out bottom. This allows the bottom to be pulled out so the clinker can drop out 
of the bottom of the burn pot. 

 

3.

 

The program on the control board. To drop the clinker you set the board to the #1 setting 
for a couple of seconds and then return the setting to the desired level. This starts a timed 
delay in the program allowing the clinker to be removed, the coals to be dropped to the 
bottom of the pot, and the Burn pot to become balanced again before the board resumes 
on the setting of your choice. 

 

Daily Maintenance – Ashby-MF with the Multi-Fuel Pot 

 

Example of Schedule for dropping Clinkers and Ash from burn pot:

 This may be required 

more than once a day, depending on the burn rate of the unit

 

and the quality of the fuel used.
