Always make sure the appliance has been turned off and is COOL before doing any of the activities required to install the Quiet DC Ventilation Fan and 12 Volt DC adapter. Do not use the adapter with a dimmer switch or rheostat controlled outlet as it will be damaged and the fan will not run.

Fan Installation

Unpack and Test

Unpack the fan and 12 Volt DC adapter. Plug the adapter into a wall receptacle that you know has power. Inset the plug at the end of the adapter cord into the jack on the back support leg of the fan. The fans will start and produce a steady flow of air. This checks that nothing was damaged in shipment.



The Quiet Fireplace Fan requires 3.3″ clearance at the front lower space between the frame and the bottom of the firebox. There is usually a clip that holds the glass plate that seals the firebox on the sides of the gap. Be careful not to measure the gap under these clips.


Locate Outlet

Direct Vent Fireplaces have a space under the firebox which contains the valves and gas pipes for the fireplace. There is normally a 115 VAC power receptacle which may or may not be turned on by from a wall switch beside the fireplace. The 12 Volt DC adapter plugs into this receptacle. If there is no switch or no receptacle we can provide a switched cable assembly or an thermostat cable assembly to work with our fan.


Plug in Adapter

The 12 Volt DC adapter supplied with the Quiet Fireplace Fan plugs into the receptacle under the firebox. In some installations only one socket is wired to the 115 VAC. Plug the adapter into the fan and turn on the wall switch to make sure you have power going to the fan. Do NOT use with a dimmer switch or rheostat controlled outlet. Some installations (below) have a receptacle that does not have a switch controlling the power, in that case a switched cable assembly or our thermostat cable assembly is required.


Insert Fan

Insert the fan assembly into the gap below the firebox being careful to not catch the metalwork on the clips that hold the glass front plate in place.


Position Fan

Position the fan assembly all the way to the back of the space under the firebox and position it in the center of the space. Make sure the fans are pointed to the BACK wall of the space. Push the fan up against the back wall and then draw it straight out by 1/8″ to 1/4″. It should not be in contact with the back wall. Make sure the adapter is plugged into the jack on the support leg of the fan.

This completes the installation. Turn on the switch and listen carefully for the sound of air flow around the firebox. After the fire has been running for 10 minutes or so, warm air from the front of the fireplace can be felt blowing out into the room.

NOTE: If the room becomes too warm and you have a central AC/Heating system, turn on the fan (auto -> fan) and circulate the additional heat through out your home.


Speed Adjustment

Each fan has a speed adjustment on the side of the support leg circuit board. When the fireplace is COLD you can make the adjustment with your fingers. Turn the black plastic shaft back and forth until you have the fan speed and sound level desired. This allows you to adjust the proper airflow for your fireplace at the lowest sound level. Do not try to control the speed by using the fan and adapter on a dimmer switch or rheostat controlled outlet. It will damage the adapter and the fan will not operate.

These fans are designed to work in DIRECT VENT GAS FIREPLACES and are NOT appropriate for use with ventless fireplaces, wood burning fireplaces and stoves due to their higher operating temperatures.
