Section III: Performance and Sizing

ELECTRIC DUCT HEATER

General Duct Heater Information

Power wiring should incorporate properly sized fuses or motor rated circuit breakers. A disconnect must be fitted within

easy access and sight of the unit. Supply voltage must be maintained /- 10% of design voltage on both single and

three phase units. Cycles must be /- 5% of design. Failure to operate within these ranges can adversely affect

performance, cause failure of the equipment, and may void warranty terms.

Duct Heater Sizes

Table 3-9. Duct Sizes

Duct Heater Installation

Flange both ends of the ducts outwards on three sides to match heater flanges as shown.

2. Fasten heater to duct using sheet metal screws for smaller heaters or bolts for larger ones.

3. Seal opening with suitable sealing compound.

If needed use additional hangers to support heater.

Electrical power connections must be made within NEC standards and local electrical codes.

6. Refer to the Field Wiring Diagram at the back of this manual for controls connection.
