An explosion proof exhaust fan is a spark resistant ventilation system that can be installed in walls to provide ventilation and temperature control inside a room or a home. There are many different models of explosion proof exhaust fan ventilation systems in the market but they do follow almost the same installation procedures. Before installing an exhaust fan on the walls of a home or a commercial property, be sure that a duct system is installed or will be installed to provide a passageway for air to escape the building. Sometimes, it is best to have the duct system installed first before the installation of the explosion proof exhaust fan. Read on for exhaust fan installation details.

Step 1 – Finding the Best Location

Find a spot on the wall that is at a high elevation in order to allow warm air to escape the room. Determine if the duct system will be installed to lead the air discharge up to the roof or directly out of the exterior of the wall. Determine also whether to install the duct system before or after the fan installation. The exhaust fan should be installed in manner that the air discharge is away from the building. For larger fans, it is best that they are mounted on walls. Smaller fans can be mounted on the ceiling.

Step 2 – Cutting an Opening

When the location for the installation is determined, use the exhaust fan template as a guide and mark the wall or ceiling where the fan will be installed. Use a saber saw to cut an opening. Mark where the screws will be placed and pre-drill them. Fit the fan on the wall to check if the opening is enough and if the pre-drilled screw holes are positioned correctly.

Step 3 – Checking the Mounting Structure

Determine if the wall provides sufficient mounting structure. If the strength of the wall cannot carry the weight of the exhaust fan, consider installing a form of support. Wooden boards can be cut and installed on the wall to provide a strong mounting structure. Consider installing shims as well if the wall is too thin. The shims will allow the fan to be further away from the mounting structure.

Step 4 – Securing the Fan to the Mounting Structure

Fit the fan into the opening and screw the all connections. Do a final inspection to check if the connections are fool proof before proceeding with the wiring connections.

Step 5 – Installing the Wiring

Before working with the wiring, turn off the power supply first. Provide a switch for the fan and a wiring that will connect it to the power supply. Locate the wiring on the exhaust fan and pull out the color-coded wires. Connect the wiring of the fan to the wiring on the switch and power supply. Be sure to follow the correct color codes. Secure the electrical covers and turn on the power supply. Test the fan.
