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.
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.
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 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 battery back-up system. It must sate “For
Igniter Equipped Appliance” and be a minimum of 750 watts.
