Re-Starting a Warm Stove. United States Stove Company 5040

OPERATION 13

RE-STARTING A WARM STOVE

If the stove has been shut off, and you want to re-start it while it is still warm, the “on/off” button must be held down for 2 seconds.

IF STOVE RUNS OUT OF PELLETS

The fire goes out and the auger motor and blowers will run until the stove cools. This will take 30 to 45 minutes.

After the stove components stop running the “Power” and the BAR GRAPH lights stay on for 10 minutes.

After the 10 minutes the “3” light on the bar graph will flash and the “Power” light will go off.

To restart, refill hopper, press “Power” button, and then press “Fuel Feed” button until pellets begin to fall into burnpot.

REFUELING

We recommend that you not let the hopper drop below ¼ full.

KEEP HOPPER LID CLOSED AT ALL TIMES EXCEPT WHEN REFILLING. DO NOT OVERFILL HOPPER.

A tool has been provided to help with the following functions:

FIGURE 23 a. Stirring pellets in hopper – unlike liquids in a tank, pellets do not drain evenly into the auger. Bridging across the opening can occur.

Pellets can hang up on the sides of the hopper. Occasionally “stirring” the hopper can help.

NOTE: To help prevent bridging of pellets, common wax paper can be rubbed on the sidewalls and bottom of the hopper.

b. Cleaning heat exchanger tubes – see instructions in “CLEANING”.

c. Scrape ashes from burnpot.

SHUTDOWN PROCEDURE

Turning your stove off is a matter of pressing the “Power” control panel switch. The red light will go out. The blowers will continue to operate until internal firebox temperatures have fallen to a preset level.

SAFETY FEATURES a. Your stove is equipped with a high temperature thermodisc. This safety switch has two functions.

1. To recognize an overheat situation in the stove and shut down the fuel feed or auger system.

2. In case of a malfunctioning convection blower, the high-temperature thermodisc will automatically shut down the auger, preventing the stove from overheating.

NOTE: On some units, once tripped, like a circuit breaker, the reset button will have to be pushed before restarting your stove. On other units the thermodisc has no reset button and will reset itself once the stove has cooled. The manufacturer recommends that you call your dealer if this occurs as this may indicate a more serious problem. A service call may be required.

b. If the combustion blower fails, an air pressure switch will automatically shut down the auger.

NOTE: Opening the stove door for more than 30 seconds during operation will cause enough pressure change to activate the air switch, shutting the fuel feed off. Close the door and press “On/Off” button to continue operation of your stove.

14 THERMOSTAT INSTALLATION

OPTIONAL THERMOSTAT

A thermostat may help you maintain a constant house temperature automatically. A millivolt thermostat is required. A fixed wall mount or US Stove’s hand held model can be used. The control panel can be set up two ways to operate your stove in thermostat mode.

THERMOSTAT INSTALLATION

• A MILLIVOLT THERMOSTAT IS REQUIRED.

• Unplug stove from power outlet.

• Remove control board from stove.

• The two thermostat wires connect to the terminal block on the lower left

side of the back of the control board.

(See figure 24)

• Insert the wires in the terminal side and tighten the two screws.

MODES

TO SWITCH BETWEEN ANY OF THE THREE MODES THE STOVE MUST

BE SHUT OFF, THE NEW MODE SELECTED, AND THE STOVE RESTART-

ED.

MANUAL MODE

• USE THIS MODE EXCLUSIVELY IF YOU DO NOT CONNECT AN OP-

TIONAL THERMOSTAT

• In this mode the stove will operate only from the control panel as detailed in the “OPERATION” section of this owner’s manual.

HIGH/LOW THERMOSTAT MODE

• USE THIS MODE ONLY IF YOU CONNECT A THERMOSTAT

• When engaged in this mode the stove will automatically switch between two settings. When warm enough, it will switch to the #1 or low setting.

The room air blower will also slow to its lowest speed.

• The Heat Level Advance setting on the bar graph will stay where it was initially set. When the house cools below the thermostat setting, the stove will switch to the feed rate of the heat level advance setting.

ON/OFF THERMOSTAT MODE

• USE THIS MODE ONLY IF YOU CONNECT A THERMOSTAT

• In this mode when the home is warm enough the stove will shut off. The fans will continue to run until the stove cools.

• When the home cools below the thermostat setting, the stove will automatically restart and run at the last feed rate setting.

FIGURE 24

NOTE: When in “high/low” or “on/off” thermostat mode –

• Do not operate the stove higher than the #3 setting.

• Set damper control rod approximately ¼” to ½” out. This will vary depending on elevation and weather conditions. Observe stoves operation and adjust damper as necessary.

OPERATION

OPERATING SAFETY PRECAUTIONS

PLEASE READ THIS!

a. Hot while in operation. Keep children, clothing, and furniture away. Contact may cause skin burns.

b. If you notice a smoldering fire (burnpot full but no visible flame) AND a heavy smoke buildup in firebox, immediately TURN OFF

the stove, but DO NOT unplug it. Do not open the door, change the damper setting or tamper with any controls on the stove.

Wait until firebox clears, and blowers shut down, do as instructed in “PRE-START-UP CHECK” and “BUILDING A FIRE”, then attempt to restart the fire. If the problem persists contact your dealer.

c. WARNING: DO NOT ADD PELLETS TO THE BURNPOT BY HAND AT ANY TIME, A DANGEROUS CONDITION COULD RESULT. d. WARNING: DURING THE START UP CYCLE; 1) DO NOT OPEN THE VIEWING DOOR; 2) DO NOT OPEN THE DAMPER MORE

THAN ¼”; 3) DO NOT USE THE FUEL FEED BUTTON (UNLESS PRIMING THE AUGER AFTER RUNNING OUT OF PELLETS). A

DANGEROUS CONDITION COULD RESULT.

e. Pellets should be stored in a dry place. The pellets should not be stored within 12” of the stove.

f. DO NOT STORE OR USE FLAMMABLE LIQUIDS, ESPECIALLY GASOLINE, IN THE VICINITY OF YOUR STOVE. NEVER USE

A GAS OR PROPANE TORCH, GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID OR

SIMILAR FLUIDS TO START OR “FRESHEN UP” A FIRE IN THIS HEATER.

g. WARNING: DO NOT OVERFIRE THIS STOVE. This may cause serious damage to your stove and void your warranty. It also may create a fire hazard in your home. IF ANY EXTERNAL PART OF THE UNIT BEGINS TO GLOW, YOU ARE OVERFIRING. Immediately press the “POWER” switch on the control panel.

h. KEEP ALL LOOSE OR MOVEABLE HOUSEHOLD COMBUSTIBLES, SUCH AS FURNITURE, DRAPES, TOYS, ETC. AT LEAST

THREE FEET FROM THE OPERATING STOVE.

i. Maintain proper ventilation. It is important that adequate oxygen be supplied to the fire for the combustion process. Modern houses are often so well insulated that it may become necessary to open a window slightly or install an outside air vent to provide sufficient combustion air.

j. Since heating with a solid fuel is potentially hazardous, even with a well made and thoroughly tested stove, it would be wise to install strategically placed smoke detectors and have a fire extinguisher in a convenient location, near an exit.

k. Do not open stove door when operating unless necessary. This will create a dirty, inefficient burn and could allow smoke spillage or sparks to escape.

l. Do not permit operation by young children or those unfamiliar with stove’s operation.

m. Do not service or clean this appliance without disconnecting the power cord.

n. Do not abuse the door glass by striking, slamming or similar trauma. Do not operate the stove with the glass removed, cracked or broken.

o. If the stove is installed in a room without air conditioning, or in an area where direct sunlight can shine on the unit, it is possible this can cause the temperature of the stove to rise to operational levels; one of the sensors could then make the stove start on its own. It is recommended that the stove be unplugged when not in use for extended amounts of time (i.e. during the summer months).
