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 personnel to supervise the initial start-up and adjustment of the unit. Persons without previous experience with 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

Direct Gas-Fired units are shipped completely assembled where shipping limitations allow. Optional inlet hoods or other large accessories are assembled and shipped mounted and wired whenever possible within limitations of shipping and handling. Any optional accessories shipped separately are shipped as assembled sections.

Shipments are made F.O.B. Dallas,Texas by flatbed truck or LTL shipment. 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 immediately with the carrier.

All Direct Gas-Fired units are given a minimum 140 point operations test and control circuit checkout before ship- ment. 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 equipment 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. The factory also offers start-up service 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 on proper operations and maintenance. Consult factory for quotations on periodic or start-up service.
