L250 HIGH LIMIT SWITCH
Your pellet appliance has a high temperature limit switch installed. If the temperature at the back of the firebox
reaches approximately 250° F, the switch will shut off the electricity going to the vacuum switch and to the
auger motor. The auger will automatically stop and the appliance will shut down when the exhaust temperature
cools to 120° F. The green auger cycle light will flash rapidly if the L250 shuts off the stove. If this happens call
your authorized dealer or Hearth & Home Technologies.
IT IS IMPORTANT TO FIND THE REASON WHY THE UNIT OVERHEATED
L120 LOW LIMIT SWITCH
This limit switch is mounted on the exhaust blower housing and has 2 main functions.
1.
Should the fire happen to go out, for any reason, this limit switch will shut the stove off when the exhaust
temperature drop below 102° F.
2.
Upon starting the appliance, the AcuTron control board has a 15 minute “Lighting Mode”, if the stove
exhaust does not reach 120° F, the limit switch opens and the AcuTron enters a 5 minute “Safety Delay”
mode.
F125 FAN LIMIT SWITCH
Your pellet appliance has a convection fan control limit switch. The room air fan’s (F125) temperature limit
snap switch automatically sets the fan on high when your stove is producing heat fast than the fan is carrying it
into the room. This may occur when the heat control lever is set at [3 or 4] and the FAN SPEED is set to a very
low or off setting. After the fan runs at this automatic high setting a few minutes, it may cycle back to its lower
setting and may continue to cycle between [HIGH] and your selected setting. The circulation (room air) fan
cycling from high to low is a normal condition as well as a safety feature of your appliance. To compensate for
the fan cycling, adjust the FAN SPEED to a high setting.
VACUUM SWITCH
This safety device (mounted on the back panel pillar) detects vacuum in the exhaust system, firebox, and air
intake. If the exhaust blower fails, the vent pipe becomes plugged, the viewing door is open, or if you are out of
pellets, this switch will sense that there is no airflow or lack of vacuum and will stop the auger from continuing
to feed pellets. The green auger cycle light will flash rapidly if the vacuum switch shuts off the stove.
