Thermostatic Fan Control easily plugs in to your Fireplace Blower- Automatically turning the blower on when the fireplace cabinet reaches 120*.
Here’s how it works… the magnetic temperature sensor is attached to the metal cabinet above the equipment compartment ie: the bottom of the actual firebox. When the metal where you have attached the sensor reaches 120* it will automatically turn on your blower… it will continue to run even after you turn the fireplace off, until the fireplace cools to below 120*. This allows you to continue to benefit from the heat produced by the fireplace for as much as 30 minutes after it has been turned off.
Thermostatic Fan Control Installation Instructions:
With Fireplace off & cool & blower unplugged…
1-Unplug the black wire from the blower & plug it onto the male lead from the thermostat- & plug the female lead from the thermostat onto the blower…The thermostat includes 24″ of wiring with male/ female type connectors that easily install on the blower. When purchased with the blower the wires comes pre-installed.…
2-“Stick” the thermostat to the bottom of the fireplace about 6″ back from door- make sure it is not on a label or near the pilot light
3-Make sure the wires from the fan power supply and the thermostat are not touching the bottom of the fireplace (top of the equipment access compartment) as this part of the fireplace can get very hot & melt the wire. Also note- the glue that holds the magnet onto the temperature sensor is rated for 180* this works fine for most gas fireplace installations, however if it is installed in a location that exceeds 180* the glue will fail & the sensor will become dislodged from the magnet. Take care that the connectors from the back of the temperature sensor do not come in contact with the metal part of the fireplace.
4- Plug the blower back in & turn on the fireplace… if the blower takes longer than 10 minutes to turn on- reposition the thermostat sensor to a place on the bottom of the firebox that gets warmer faster. All fireplaces, burners, log assemblies are different and all fireplaces have hot & cool spots- move the sensor around until you find the spot that turns the blower on fairly quickly. *note some vent free fireplaces are built in a way that prevents this part of the cabinet from warming up to the required 120*… if you are unsure about your fireplace- you should turn your fireplace on & see if the cabinet gets hot to the touch.
5-The magnet should be installed horizontally as shown in the picture above… the magnet is designed to hold it in place in this configuration…if installed vertically “up the side of the firebox” the sensor will eventually “fall off” and with the sensor away from the cabinet- the blower will stay in the off position.
