MOUNTING

Multiple Duct Heaters: Up to six duct heaters may be combined into a heating bank as shown in Figure 15. When called for on order, brackets will be furnished for fastening flange type duct heaters together to form a bank. Heater will be coded for proper assembly in the field.

Two to six duct heaters (with flange) may be installed in a hor- izontal or vertical duct.

Heaters must be mounted in the position designated by arrows on the heater frame. (Refer to Figure 16).

The heater terminal box on vertical duct installations can be located on any side of the duct but for horizontal duct installation the terminal box must be on the side of the duct.

This heater is not intended for use in hazardous atmospheres where flammable vapors, gases, liq- uids, or other combustible atmospheres are pre- sent as defined in the National Electric Code. Failure to comply can result in explosion or fire.
