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.
