AUTOMATIC SAFETY FEATURES
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 drops below 120deg F.
2. Upon starting the appliance, the AcuTron control board has a 15 minute “Lighting Mode”, if the stove
exhaust does not reach 120deg F in that 15 minutes the stove will shut off. As soon as the stove exhaust
does reach 120deg F, the limit switch opens and the AcuTron enters a 5 minute “Safety Delay” mode.
F140 FAN LIMIT SWITCH
Your pellet appliance has a convection
fan control limit switch. The room air
fan's (F140) temperature limit snap
switch automatically sets the fan on high
when your stove is producing heat faster
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
higher setting.
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 250deg 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 (120deg F). If this happens call your dealer or Dansons Customer Service (1-866-456-9269).
IT IS IMPORTANT TO FIND THE REASON WHY THE UNIT OVERHEATED.
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 a lack of vacuum and will stop the auger from continuing to feed pellets.
If the power does go out, the pellet appliance will stop running. When the power comes back on,
the stove will not restart if the switch is in the manual mode. If the exhaust temperature is above
120deg F or the switch is in the manual position, the stove will start to feed pellets again and may
re-light itself.
NOTE: If power outages are a concern you may wish to purchase a back-up generator system.
