before wiring or servicing. 

2.   All wiring procedures and connections must be in accordance 

with the National and Local Codes having jurisdiction and the 

heater must be grounded. 

3.   Verify the power supply voltage coming to heater matches the 

ratings as shown on the heater nameplate.

CAUTION: 

ENERGIZING HEATER AT A VOLTAGE GREATER THAN 

THE VOLTAGE PRINTED ON THE NAMEPLATE WILL DAMAGE 

THE HEATER AND VOID THE WARRANTY AND COULD CAUSE 

A FIRE.

provision must be sufficient strength to support the total weight 

of the heater plus the weight of the mounting provisions. Failure 

to properly secure the supporting members of the building 

structure could allow the heater to fall.

INSTALLATION
INSTRUCTIONS

Locating the Heater

The heater should be installed out of traffic areas and at least 6'
off the floor. The direction of air flow should not be restricted (ie:
by columns or machinery) and the air flow should wipe exposed
walls, rather than blowing directly at them. When more than one
heater is used in an area, the heaters should be arranged so
that the air discharge of each heater supports the air flow of the
others to provide best circulation of warm air, as indicated in 
Figure 3, below.
