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 qualified field 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
personnel as an aid in troubleshooting and proper
maintenance.
B. Shipping
Base Direct Gas-Fired units are shipped completely
assembled where shipping limitations allow. Optional
inlet hoods, filter and/or damper sections, or other
large accessories are assembled and shipped
mounted and wired whenever possible within limita-
tions of shipping and handling. Any optional accesso-
ries shipped separately are shipped as assembled
sections. Any wired accessories which have been
disassembled for separate shipment require no
additional conduit or wire for field reassembly. All wire
leads will be tagged for ease of reconnection in the
field.
Shipments are made F.O.B. Dallas, Texas by flatbed
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 filed 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 efficient 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.
