BLOWER THEORY OF OPERATION
All Country Flame catalytic stoves come standard or have optional room air blower systems available. These room air
blower systems are designed to pull cool air from the living space into, through, and across the hot catalytic stove body
thereby returning the exchanged air to the home at an elevated temperature (heated). These blower systems add to the
overall heating efficiency by ensuring that a stove does not rely solely on heat convection to provide warmth to a home. It
is important to note that in the event of a power outage, all Country Flame catalytic stoves will continue to operate
properly and no damage should occur to the blower system from over heating.
All Country Flame blower systems are designed to turn on and off automatically as the temperatures rise and fall inside
the firebox. The blower systems are automated with a thermal 110° F snap disk installed in the blower’s electrical system.
This thermally activated switch automatically turns the blower on and off. The blower is turned on as the air surrounding
the snap disk reaches approximately 110° F. As the air temperature rises, the thermal snap disk closes, completing the
electrical circuit thus allowing the fan motor to be activated. Household air is pulled into the stove, heated, and then
returned back to the home. In the event the home air temperature drops below approximately 90° F, the switch
deactivates, turning off the stove blowers.
The following information and schematics are provided for informational purposes only. A qualified electrician should
perform all repairs or installation of the electrical power required for Country Flame stoves.
WARNING: Lethal electrical power is present in home electrical circuits. All Country Flame stoves require standard
household power at 120 volts, 60 Hz, and 15 amperes. This standard household power should be provided through a
National Electric Code approved 3-wire power outlet that is properly grounded. Installing house wiring incorrectly,
failing to maintain proper polarity in either the plug or receptacle, or removing the grounding pin can lead to potentially
fatal shock hazards. Country Flame strongly recommends the use of a qualified electrician to install, maintain, or service
any part of a stove’s electrical system.
The schematics provided on the next several pages are for informational purposes. Changes do occur from time to time
on stove wiring systems and Country Flame reserves the right to update and change the schematic at its discretion. In the
event of any discrepancy between the information provided and the actual wiring of a stove, please contact Country Flame
or one of its local dealers.
MODEL BBF, B
The Model BBF and Model B catalytic stoves come standard with a blower system that can move 600 cubic feet per
minute (CFM). The blower system is located in a convenient blower tray that provides for easy cleaning. The blower tray
access is achieved by removing the grill below the front ash lip. The blower tray can then be slid forward and removed.
NOTE: A standoff bolt keeps the blower tray from rattling during operation. This bolt will need to be loosened and
lowered for tray removal.
The blower system operates when the temperature of the 110º F thermal snap disk, located in the blower tray, completes
the electrical circuit. When the thermal snap disk cools to somewhere around 90º F, the electrical circuit is broken and the
blower system will shut down. A bypass switch is provided on the front of the blower tray so that the thermal snap disk
can be bypassed. FIGURE 21 shows the blower tray electrical schematic. This allows for testing the operation of the
blower system without requiring the system to be hot. The front label is provided for clarification when operating the
blower system.
