Frequently asked questions.
Can I test to see if the Ecofan motor is working?
Please DO NOT take the Ecofan apart to perform the test. Ensure that the Ecofan has cooled down completely.
Any 1.5 volt battery will work to see if the motor is working. In using a A-A battery, the motor in all the fans will spin around the same speed as if the fan is on a 200 to 300 C wood stove. If the motor is quick to start and spins quickly then the motor should be fine. Tape two wire leads to the battery terminals using electrical tape and then touch the wires to the motor leads.
The 812 draws about ¾ to 1 watt of power.
How does the Ecofan work?
The Ecofan generates its own electricity through the difference in temperature. The base must make contact with a heat source of at least 150°F (65°C) and the top of the fan must remain cool. The Ecofan needs to draw cooler air from behind in order to operate. The actual rotation of the blade as well as the cooler air and the heat source are the essential elements needed for the Ecofan to operate.
My Ecofan worked great and now it is slowing down. What should I do?
Please call our Customer Service representatives at 1-800-567-3556 ext.227 or email us at email@example.com and we will be glad to assist you.
How do I use an Ecofan?
Simply place your Ecofan on the top of your stove*, away from the chimney pipe, allowing the back of your fan to have access to cooler, room temperature air. The thermoelectric modules require a temperature difference to create the electricity needed to operate the fan’s motor.
*Not recommended for wood or gas stove inserts
Where should I place my Ecofan?
Be sure to position the Ecofan on a smooth flat surface on your stovetop near the side or back of the stove where cooler air can be drawn from behind and over the cooling fins. Do not place your Ecofan in the center of the stove, in front of the stovepipe or at the front of the stove.
What temperature does the surface need to reach in order to operate?
The Ecofan will start to rotate once the base of the fan has reached a temperature of 150ºF (65°C).
What will void my Ecofan warranty?
Caframo will warranty any product bought through a recognized retailer. Products bought through individuals or on-line auctions have no warranty. The warranty does not cover abnormal wear or damages resulting from accident, misuse, abuse or, if applicable, breakage (when such breakage is not due to a manufacturing defect) and any other incidental or consequential damages. Simply put -If you overheat your fan or drop your fan your warranty will be voided.
Can I use the Ecofan on a fireplace?
Unfortunately no, the Ecofan generates its own electricity through temperature differential. The base must make contact with a heat source of at least 150ºF and the top of the fan must remain cooler. The Ecofan needs to draw cooler air from behind in order to operate.
How should I store my Ecofan during the off-season?
Once the Ecofan is placed properly on your woodstove there is no need to move it. We recommend leaving it in its position on top of the stove year round. If you want to remove it for any reason, please take care to store it in a location where it cannot be knocked over or dropped.
Where can I purchase an Ecofan?
Caframo manufactures Ecofans and does not sell to consumers. Please consult the ‘Where to Buy’section under ‘Customer Support’ to find a retailer in your area. If you are having difficulty locating a retail location near you, please feel free to call our customer service representatives at 1-800-567-3556 ext. 227 and they will guide you to the appropriate retailer in your area.
I have model 812AM-BBX and the blade has started to make an intermittent noise. It’s silent at first and then as it warms up the noise gets more constant. It is a rapid tick tick noise.
There is a problem with the balance of the blade that causes it to make this noise. The blade should be replaced.
My Model 812 has begun to shake a lot – could it be the blade?
Likely the blade is bent somehow making it off balance. The blade should be replaced.
Can I test the module?
The module can be checked by the following:
Voltage is typically 1.5 VDC. On a hot wood stove voltage can exceed 2.2 VDC
TE Module resistance is a little difficult to measure as an AC resistance must be measured. To that end, AC resistance is about 3.3 ohms
Motor resistance is difficult to measure. A brushed DC motor is used and so armature location will change the resistance. An old and worn motor will show open in some positions
If the fan has not been dropped or abused then in most cases the motor dies. The motor brushes wear out. The TE module is very robust and it is a solid state device. However, a shock can damage the module or extreme temperatures. If the fan simply starts to slow down and is difficult to start than it is most likely the motor.
Can the module be replaced?
Usually the module will fail due to overheating or it is cracked from dropping and that to replace the module requires the use of specialized pressure measuring equipment. Improper installation of the module will cause it to work poorly, or to fail immediately, or to fail sooner than if installed properly.
I’m thinking of building in an on/off-switch to the motor. Would that work?
Adding a cutoff switch is not a good idea. The air movement from the fan protects the electrical module from overheating and on a hot stove with the motor disabled there is a chance the module could overheat. It would be best to move the fan to a colder section of the stove or off the stove altogether.
Where do I find the serial number on my Ecofan?
Manuals, documentation, sell sheets and other downloadable materials.
