removal of the clinker. The time it takes the pot to fill up with ash depends on the quality

of the pellets and on the quantity of pellets burned. The interval of dumping the ash is

directly related to the rate of burn. A Furnace running on a thermostat cycling at a

moderate rate will generally last approximately 24 hours. However if the Furnace is

running continuously on the highest setting the Ash will need dumping every 10 to 12

hours. It is the responsibility of the Owner/User of the furnace to determine the

frequency of dumping the Ash, based on the rate of burn and the quality of pellets

(ash content).

Clinker/Ash Removal.

Once a clinker/ash has formed in the burn pot, it must be removed or the Furnace 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 Furnace 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.

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 on the #1

setting for a couple of seconds and then return the Furnace to the desired setting.

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 you choice.

NOTE: WHEN YOU FIRST OPERATE YOUR FURNACE, CHECK TO

DETERMINE THE NEEDED CLEANING FREQUENCY. THE FURNACE

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 FURNACE 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.
