SECTION II - GENERAL INFORMATION
A. Purpose
The purpose of this manual is to present a guide for
proper installation, maintenance, and operation of the
Direct Gas-Fired System, and supplement,
but not to
replace
, the services of quali
fi
ed
fi
eld service person-
nel to supervise the initial start-up and adjustment
of the unit. Persons without previous experience with
large commercial and industrial heating equipment
should not attempt the initial adjustment and checkout
procedure which is essential before such installations
may be considered ready for operation. This manual
should be made readily available to all operating per-
sonnel as an aid in troubleshooting and proper mainte-
nance.
B. Shipping
Base Direct Gas-Fired units are shipped completely
assembled where shipping limitations allow. Optional
inlet hoods,
fi
lter and/or damper sections, or other
large accessories are assembled and shipped mount-
ed and wired whenever possible within limitations
of shipping and handling. Any optional accessories
shipped separately are shipped as assembled sec-
tions. Any wired accessories which have been disas-
sembled for separate shipment require no additional
conduit or wire for
fi
eld reassembly. All wire leads will
be tagged for ease of reconnection in the
fi
eld.
If the unit and/or accessories cannot be installed
immediately, they should be stored in a clean dry
environment. If this is not possible and the unit
must be stored outdoors, it should be protected
from the weather with tarpaulins or plastic
coverings. Do not assume that simply covering a
unit will keep insects, dust and condensation out
of the unit and critical components. Rotate the
fan(s) monthly.
Prior to beginning installation of a unit that has been in
storage for weeks or months, the unit and its compo-
nents should be closely inspected.
Shipments are made F.O.B. Dallas, Texas by
fl
at-
bed truck. The unit is securely strapped, tied, and
blocked to prevent shipping damage. All shipments
are checked by an inspector before they are accepted
by the carrier. Parts that are shipped unmounted are
noted on the bill of lading. These parts, where feasible,
are packaged and shipped with the units. Upon receipt
of shipment, all units should be checked against the
bill of lading to insure all items have been received. All
equipment (and any optional accessories) should be
checked carefully for physical damage in the presence
of the carrier’s representative. If parts are missing or
damage has occurred, a claim should be
fi
led immedi-
ately with the carrier.
All Direct Gas-Fired units are given a complete opera-
tions test and control circuit checkout before shipment.
Copies of the wiring diagram, piping diagram and
bill of material are included with each unit shipped. If
correspondence with the factory is necessary, please
provide the unit model and serial number.
C. Optional Factory Service
Periodic service on any piece of mechanical equip-
ment is necessary for ef
fi
cient operation. A nationwide
service support network is available to provide quick
and dependable servicing of make-up air, heating,
ventilating, or air handling types of equipment. Factory
start-up service is also available which includes the
presence of a service engineer to supervise the initial
start-up and adjustment of the equipment and provide
instructions for the owner’s maintenance personnel in
proper operations and maintenance. Consult factory
for quotations on start-up or periodic service.
