Installation
Location of Accessories
Where applicable, standard or optional accessories will be placed inside the fan
section of the unit for shipment, and must be removed and installed by the
mechanical or electrical contractor. Remotely located discharge or inlet dampers
must be equipped with an end switch and interlocked to ensure maximum design
opening before starting and running circuits may be energized.
Field constructed intake accessories should be properly designed to minimize the
entry of rain and snow.
Adequate building relief must be provided, so as to not over-pressurize the
building when the heater is operating at its rated capacity. This can be
accomplished by taking into account, through standard engineering methods,
the structure’s designed infiltration rate, by providing properly sized relief
openings, by interlocking a powered exhaust system, or by a combination of
these methods.
Electrical Connections
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects and discharge all
motor start/run capacitors before servicing. Follow proper lockout/tagout
procedures to ensure the power can not be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
WARNING
Electric Shock!
Controls must be protected from exposure to water. Allowing water to drip on
the ignition system could result in death or serious injury.
WARNING
Live Electrical
Components!
During installation, testing, servicing and trouble shooting of this product, it
may be necessary to work with live electrical components. Have a qualified
licensed electrician or other individual who has been properly trained in
handling live electrical components perform these tasks. Failure to follow all
electrical safety precautions when exposed to live electrical components could
result in death or serious injury.
All electrical connections must conform to the current edition of ANSI/NFPA No.
70 National Electrical Code and applicable state and local codes; in Canada, to
the Canadian Electrical Code, Part 1 CSA Standard C22.1 and applicable
provincial and local codes.
Since shipment of unit may require disassembly after factory check and test,
reconnection of some electrical devices will be required in the field. connect
electrical wires (supplied in factory furnished conduit) to appropriate terminals.
All leads are tagged to help facilitate field connections. See the wiring diagram
provided with the equipment. Complete all wiring to any optional accessories as
shown on the unit model number and electrical wiring diagram as required
before applying voltage to the unit.
Entry location for all field-installed and control wiring is through the control
panel.
