ECO CHOICE PELLET STOVE SERVICE MANUAL

THERMOCOUPLE TESTING

THE THERMOCOUPLE IS MADE UP OF TWO DISSIMILAR METALS THAT WHEN JOINED TOGETHER PRODUCE A

SMALL AMOUNT OF ELECTRICITY WHEN HEAT IS APPLIED. THE HOTTER THE FIRE THE HIGHER THE VOLTAGE

THAT IS PRODUCED. THIS THERMOCOUPLE WILL TOP OUT AT AROUND 30 MILLIVOLTS (DC) WHILE THE STOVE IS

BURNING ON HIGH. THE FUNCTION OF THE THERMOCOUPLE IS TO SENSE THE TEMPERATURE IN THE FIREPOT.

IF THE THERMOCOUPLE IS FRACTURED, IT WILL NOT PRODUCE VOLTAGE.

ALSO, AN AMBER LIGHT IN THE CONTROL WILL FLASH IF THE CIRCUIT IS OPEN OR IF THE THERMOCOUPLE IS

FRACTURED.

1) ATTACH A DIGITAL VOLT METER TO THE TWO THERMOCOUPLE CONNECTORS ON THE HARNESS

NOTE: BE SURE TO SET THE METER TO MILLIVOLTS (DC) AND A JUMPER WIRE MAY NEEDED TO CHECK

MILIVOLTS WHILE THE THERMOCOUPLE IS HOOKED UP.

2) APPLY HEAT TO THE THERMOCOUPLE TIP IN THE FIREPOT

IF THE THERMOCOUPLE STARTS PRODUCING VOLTAGE: CHECK TERMINAL CONNECTIONS ON THE WIRE

HARNESS OR REPLACE THE CONTROL BOX.

IF NO VOLTAGE FROM THE THERMOCOUPLE: REPLACE THE THERMOCOUPLE

FIREPOT AND EXHAUST SYSTEM TROUBLE-SHOOTING

THE FIREPOT IS MADE OF CAST STEEL AND IS DESIGNED WITH AIR INTAKE HOLES THAT SWIRL THE

FIRE AND HELP TO REMOVE THE ASH CREATED FROM THE BURNING OF THE PELLET FUEL. THERE IS

ALSO A SLOT OR AIR PASSAGE IN THE BOTTOM SIDE OF THE FIREPOT THAT ALLOWS HOT AIR FROM

THE IGNITER TO LIGHT THE PELLET FUEL. DURING THE BURN CYCLE PROCESS IN THE FIREPOT,

“CLINKER” MATERIAL WILL START TO BUILD-UP. (SEE *FIGURE 1) THE RATE OF THIS BUILD-UP WILL

DEPEND ON THE QUALITY OF THE PELLET FUEL BEING USED. OVER TIME THIS BUILD-UP OF CLINKER

MATERIAL CAN OBSTRUCT THE AIR PASSAGES AND CAN CAUSE PROBLEMS WITH THE OPERATION OF

THE FIREPOT. THIS CAN ALSO CAUSE THE FIREPOT CLEAN OUT DOOR TO BECOME HARD TO PULL IF

THE FIREPOT IS NOT CLEANED ON A REGULAR BASIS.

THE FIREPOT IS JUST ONE COMPONENT OF THE TOTAL COMBUSTION SYSTEM. COMBUSTION AIR

FLOWS INTO A ROUND OPENING LOCATED AT THE LOWER REAR OF THE UNIT. (SEE *FIGURE 2) THIS

AIR TRAVELS INTO THE ASHPAN AREA LOCATED BELOW THE BOTTOM OF THE FIREPOT.

(SEE *FIGURE

3) COMBUSTION AIR WILL FLOW THROUGH THE AIR OPENINGS IN THE FIREPOT AND IS THEN TRANS-

FORMED INTO EXHAUST GASES. THE EXHAUST GASES WILL FLOW FROM THE FIREPOT TO THE

BAFFLE PLATES AND REAR FIREBOX AREA. (SEE *FIGURE 4) THE EXHAUST WILL FLOW FROM THE

BAFFLE AREA TO THE EXHAUST BLOWER HOUSING. (SEE *FIGURE 5) THIS COMPLETES THE NEGATIVE

PRESSURE OR VACUUM PORTION OF THE COMBUSTION SYSTEM. AFTER THE EXHAUST ENTERS THE

EXHAUST BLOWER HOUSING IT IS THEN PUSHED OUT INTO THE VENT PIPE OR CHIMNEY PORTION OF

THE EXHAUST SYSTEM.

(SEE *FIGURE 6)

IF ANY PART OF THE EXHAUST SYSTEM IS RESTRICTED, THE STOVE WILL BURN DIRTY WITH TALL

LAZY FLAMES. THE STOVE MAY ALSO EXPERIENCE PROBLEMS WITH LIGHTING THE PELLET FUEL DUE

TO THE REDUCED AIR FLOW THROUGH THE FIREPOT.

IF ANY PART OF THE EXHAUST SYSTEM IS BLOCKED, THE STOVE WILL NOT FEED BECAUSE THE

VACUUM SWITCH WILL NOT ENGAGE. NORMALLY THE STOVE WILL HAVE BETWEEN .08 TO .16 INCHES

OF WATER COLUMN IN THE FIREBOX WITH STOVE SET ON THE HIGH FEED RATE.

CLEANING & MAINTENANCE TIPS

CAUTION: REMEMBER TO UNPLUG THE STOVE BEFORE PERFORMING ANY

CLEANING OR MAINTENANCE ON THE STOVE.

PAGE 24

ECO CHOICE PELLET STOVE SERVICE MANUAL

CLEANING & MAINTENANCE TIPS

FIREPOT:

THE FIREPOT NEEDS TO BE CLEANED AS NEEDED. THE BUILD-UP OF CLINKER

MATERIAL WILL DEPEND ON THE QUALITY OF THE FUEL BEING USED. IN SOME

CASES, IT MAY BE NECESSARY TO CLEAN THE FIREPOT ON A DAILY BASIS.

FIREPOT CLEANING INVOLVES SIMPLY PULLING THE CLEANOUT ROD ON THE RIGHT

SIDE OF THE STOVE. IF THE ROD IS HARD TO PULL, IT MAY BE NECESSARY TO USE

THE SCRAPER OR SCREW DRIVER TO CHIP AWAY THE CARBON MATERIAL THAT HAS

BUILT UP ON THE BOTTOM PLATE OF THE FIREPOT. ONCE THE DEBRIS IS CHIPPED

AWAY, THE ROD WILL BE EASY TO PULL.

FIREBOX ASH:

THE FIREBOX ASH SHOULD BE REMOVED AT THE SAME TIME THAT THE FIREPOT

IS CLEANED. FREQUENT CLEANING OF THE ASH IN THE FIREBOX WILL HELP SLOW

DOWN THE BUILD-UP OF ASH IN THE EXHAUST BLOWER AND VENT SYSTEM. REMEM-

BER TO DEPOSIT ASHES IN A NONCOMBUSTIBLE CONTAINER.

VENT / CHIMNEY SYSTEM:

THIS NEEDS TO BE CLEANED AND INSPECTED AT LEAST ONCE A YEAR. IT MAY BE

NECESSARY TO PERFORM MORE FREQUENT CLEANING IF THERE IS A LOT OF HORI-

ZONTAL PIPE SECTIONS. ASH WILL BUILD UP MORE QUICKLY IN THE HORIZONTAL

SECTIONS.

BLOWERS:

THE BLOWERS MAY ONLY NEED TO BE CLEANED ONCE A YEAR. IF THE USE OF

THE STOVE IS HEAVY, THEN IT MAY NEED TO BE DONE MORE FREQUENTLY. IF THE

BLOWER IS GETTING NOISY, THEN THE FAN BLADES WILL NEED TO BE CLEANED.
