WARNING
To reduce the risk of fire, electric shock, or injury to persons,
observe the following:
• Installation work and electrical wiring must be done by qualified per-
son(s) in accordance with all applicable codes and Standards, including
fire-rated construction.
• Sufficient air is needed for proper combustion and exhausting of gases
through the flue (chimney) of fuel burning equipment to prevent back
drafting. Follow the heating equipment manufacturer's guideline and
safety Standards such as those published by the National Fire Protection
Association (NFPA), and the American Society for Heating, Refrigeration
and Air Conditioning Engineers (ASHRAE), and the local code authorit-
ies.
• When cutting or drilling into wall or ceiling, do not damage electrical wir-
ing and other hidden utilities.
• Ducted fans must always be vented to the outdoors.

It is very important that there are no obstacles within the indicated area.
Obstacles within this area will disrupt the airflow and may cause the fan to
vibrate.
Mounting
The fan must be mounted on a rigid structure. In greenhouses, the fan should
preferably be mounted directly on the truss of the greenhouse. A special
bracket kit is available as an optional accessory. This bracket kit will fit the
most commonly used greenhouse trusses. Contact your supplier for more
information.
