GENERAL
These heaters are designed to be installed in either a horizontal or vertical duct in one of the six positions shown in figure 16. The heater is constructed with individual metal sheath fintube elements mounted to a heavy gauge metal terminal box.
Due to the various options and materials available, check the nameplate attached to the heater terminal box with the catalog number designation system on page 7 before installing to insure the heater you received conforms to your specification.
Please read these directions carefully to insure all limitations are properly observed and all wiring and controls are properly installed and connected.
IMPORTANT — Observe at least one complete heating cycle operation before leaving the installation.
