17 hours or stretch out to over 100 hours when less heat is required. A thermostat is used to regulate the heat output of the stove. When no heat is needed, the stoker stops and only runs to maintain the fire. If heat is needed, the thermostat can turn on the stoker at any time. - Page 4 If you don’t, the feeder will over-fire the stove and waste coal. Doing this once or twice a year will not damage your stove as long as it is hot and burning. The damage is caused when the hopper has wet coal in it when This will cause rust and corro- th e s to v e is c o ld .

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 con- stantly. -
Page 14: Feed Adjustment
To start a fire you first pour rice coal into the hopper. With the thermostat turned up and the stoker running, the coal will begin to feed onto the grate inside the stove. This process can be speeded up by adjusting the feed rate to the maximum position. When the coal starts to come up out of the grate and is almost up to the area where the holes start, turn the feed rate back to about 3/8"... -

Page 17: Trouble-Shooting
Lack of draft or a down draft in the chimney will cause gases to escape from the unit. No stove will function properly without draft. Any draft problem should be corrected before use. A draft inducer may be installed to increase draft in marginal situations. - Page 18 The installation should be performed by your dealer who is factory trained to correct any problem on initial start-up. After proper installation, many years of trouble-free operation can be expected. Stoker Control Trouble-Shooting This trouble-shooting guide is designed to help the customer find basic problems external to the stoker timer.
