Type HVH Horizontal/Vertical Unit Heater
Heater Location Instructions:
Arrange units so their discharge air streams:
A. Are subjected to a minimum of interference from columns,
machinery and partitions.
B. Wipe exposed walls without blowing directly at them.
C. Are directed away from room occupants in comfort heating.
D. Are directed along the windward side when installed in a build-
ing exposed to a prevailing wind.
E. See additional mounting limitations in Table D.
Locate thermostat on interior partition walls or posts away from
cold drafts, internal heat sources and away from heater discharge air
streams.
Small rooms can be heated by one unit heater. Where two walls
are exposed, the heater should be mounted as shown in Figure 1.
Large rooms require multi-unit installation. Number and capacity
of units will be determined by volume of building and square feet of
floor area to be heated. Arrange units to provide perimeter air circula-
tion where each unit supports the air stream from another.

25 to HVH-50).
7. Terminals on contactor or on line voltage terminal block are supplied
to be connected to accept the correct size power supply wire. Copper
rated at 600V and 60˚C is satisfactory for the heater branch circuit.
8. Electrical accessories, either kits or factory-installed options, are
shown connected by a dash line on the heater wiring diagram.
9. Wiring connections are to be made on designated wire leads as
shown in the wiring diagrams located inside the access door.
10. Louver adjustment (Do not attempt to adjust while heater is op-
erational): Louvers have been preset at factory with the minimum
open angle. Decreasing the 45˚ angle may result in high tempera-
tures and functioning of the over temperature control. To increase the
opening angle, grasp the left end of louver with the left hand using
the index finger and thumb. Grasp right end of louver with right hand
in the same manner. Twist louver to the desired position.
