choose an approprIate locatIon to Install the devIce:
• Ideally in a service room intended for this purpose, where the temperature is maintained between 10°C and 40°C.
• Close to an exterior wall, so as to limit the length of the air inlet insulated ducts
• Away from the electrical panel and other fire hazards.
• make sure you can easily access the inside of the device to perform maintenance (24”minimum clearance required from the main entrance
door of the device).
• leave a minimum space of ½” above the device.
InstallIng the duct system
• Plan the simplest system, using the least number of elbows and joints.
Keep the length of insulated ducts to a minimum to prevent choke and
improve ventilation.
• Do not install elbows less than twice the diameter of the device’s duct
• use only rigid metal ducts.
• Insulate the inlet ducts only. It is not necessary to insulate the outlet
ducts.
InstallIng the fresh aIr Intake hood
Choose the appropriate location to install the fresh air intake hood:
• The fresh air intake hood must be installed at least 18 in. above the
ground.
• make sure the fresh air intake hood is at least 6 ft. away from the fol-
lowing elements: garbage can or any other contaminating source, gas
meter outlet, dryer outlet, any other combustion source outlet.
• Install the fresh air intake hood at least 3 in. from the edge of the build-
ing to avoid turbulence, which could cause dust to enter the hood.
• See the illustration below on how to connect the fresh air intake hood
to the exterior hood (louver not included).
