4. In general, locate heater approximately 1 foot from the floor, but not
less than 6 inches, for best overall results. Heater, however can be
located anywhere to meet unique requirements of any particular appli-
cation.

crete, block, plastered walls, metal framework, etc.-using appropriate
hardware.
6. Standard heaters are mounted in a vertical position with the terminal
end on the bottom. This unit has special baffle plates and vent holes
in the cover to ensure sufficient convection currents. Make sure that
the heater is mounted so that the
mounting label located on the back
panel points up as shown in Figure
1 . The end covers will be at the top
and bottom of the heater with the
terminal access at the bottom end.
WARNING: Never recess
heater into wall.
