England's Stove Works 25-CAB80 Installation & Operation Manual page 27

 Burning improper fuels ‐ this unit is designed and approved to burn only premium grade wood pellets.
Burning other fuels such as cherry pits, shelled corn, or pea/rice coal is not only prohibited, the
practice can lead to significant damage done to the unit in a relatively short time.
 Defective firebox sensor ‐ test in diagnostic mode; the display should read "firebox 87F" (or higher). If
the sensor's temperature is below 87F, it will display "FIRE SENSOR UNPLUGGED OR COLD". Use a
lighter to heat up the firebox sensor briefly and observe the display for a change in the sensor's
reading. If the reading does not change, or ‐ in the case of an over temp error is reading an extremely
high number when the sensor is obviously cold ‐ replace the sensor.
Vacuum loss:
When the stove is running, a vacuum sensor is monitoring the amount of airflow through the burn chamber. This device
will stop feed if this flow is interrupted, and resume feeding when the flow is reestablished. If the airflow is interrupted
for more than 30 seconds, the unit will shut down with a vacuum loss error.
Potential causes:
 Front door open/gasket leaking ‐ the front door must remain closed to allow pressure to be registered
by the vacuum switch. Also, the gasket that seals the door should make a relatively airtight seal to the
face of the unit. Inspect this seal using a "dollar bill test": With the stove off and cool, fold a dollar bill
in half long‐ways and insert it between the open door and the stove face, then close and latch the
door. Pull on the dollar bill and note there should be resistance to the bill, caused by being pinched
between the gasket and the stove face. Repeat this process in several places around the door. If the bill
will slip out with no resistance, the gasket should be replaced.
 Draft (exhaust) blower not running ‐ if the draft blower is stuck, defective or plugged up and is unable
to run, the unit will not feed. The airflow generated by the draft blower activates a vacuum switch that
tells the control board the front door is closed and the draft blower is pulling sufficient air through the
burn pot to support the fire.
o Solution: Clean the stove and flue system. Clean out the draft blower and check to ensure the
impellor rotates freely. Check wire connections at the blower; test in diagnostic mode. If the
draft blower still does not run, replace the draft (exhaust) blower.
 Improper venting method ‐ as stated above, one of the key requirements for proper operation is
proper airflow through the system. Venting systems with excessive elbows and/or long horizontal runs
can restrict the flow of air to the point that the vacuum switch may not receive enough pressure to
hold it closed. This would prevent feed, as the control board would assume the front door is open.
Refer to the installation guide to determine if the installation is within specifications.
 Blocked flue/excessive ash buildup in stove ‐ for airflow to be sufficient to supply enough pressure to
the vacuum switch, the flue and the stove itself must be clear of blockage or excessive buildup. This
situation can reduce the amount of airflow to the extent that it causes the vacuum switch to open.
Proper cleaning of both the flue system and the stove must be performed on schedule to ensure the
required airflow can be maintained.
