INSPECTION OF EQUIPMENT
All shipments are made F.O.B. the factory. The unit is securely strapped or blocked to prevent shipping damage and each
shipment inspected prior to leaving the plant. All parts, where feasible, are strapped to or included in the unit. Upon receipt
of goods, check the shipment against the bill of lading to ensure all items have been received. Carefully check the unit for
physical damage in the presence of the carrier’s representative. Should parts be missing or damage noted, file a claim
immediately with the carrier. ICE does not assume responsibility for the handling of the goods in transit and is not
responsible for the initiation of freight claims.
INSTALLATION AND SERVICE INSTRUCTIONS
Direct Gas Fired Air Heaters
LOCATION OF UNIT AND DISTRIBUTION
Inlet
The intake shall be designed and located to prevent snow, rain, flammable gas, toxic gases and other deleterious materials
from entering the unit. (Less than 500 F.P.M. is an accepted velocity.)
INSTALLATION
Smaller models are shipped as one total unit. All other models are shipped in sections that are easily erected on the job site.
The main sections consist of a burner damper section that contains the motor, and a blower section. The secondary sections
are the filter, louver, mixing box etc., which are added in sections as required.
1. All sections are pre-drilled and are bolted together in the field (as per Figure 1).
2. Belts must be installed on the motor, and limit and discharge controls may have to be mounted and/or wired.
3. When clearance is not a factor, ensure that the unit is adequately protected from obstruction.
NOTE: On roof top units the joints will have to be caulked to prevent rain from entering the unit.
Indoor Suspension
On indoor models holes at the base of the units are provided for 5/8” suspension rods (see Figure 6). Unit must be lifted and
handled from the lifting holes provided at each end of the channel iron, when suspending from the ceiling. If units are to be
lifted from the bottom for mounting on a platform (as with a forklift), unit must be supported.
NOTE: DO NOT LIFT CABINET WITHOUT THIS SUPPORT.
Rooftop Installation
Support rails (minimum of 4” high) must be provided underneath the unit. In some cases, more height may be required when
installing the supply duct through the roof (see Figure 1) or if a unit is a bottom discharge (see Figure 2).
Minimum clearance from the unit, to combustible construction, is clearly marked on the rating plate attached to the unit.
No source of flammable vapors, gases or dust shall be with in 20’ horizontally of any unit unless that source is separated from
the unit by an enclosure of fire and vapor resistive materials.
On indoor suspended units, when necessary to provide working clearance beneath the unit, the installation shall be made at a
suitable height above the floor.
