Vent
WARNING
Personal injury or property damage
can occur from cover failure due to
overpressure. Ensure that the
housing vent opening is open and
free of debris to prevent pressure
buildup under the cover.
WARNING
This unit vents the supply medium
into the surrounding atmosphere.
When installing this unit in a
non-hazardous (non-classified)
location in a confined area, with
natural gas as the supply medium,
you must remotely vent this unit to a
safe location. Failure to do so could
result in personal injury or property
damage from fire or explosion, and
area re-classification.
When installing this unit in a
hazardous (classified) location remote
venting of the unit may be required,
depending upon the area
classification, and as specified by the
requirements of local, regional, and
national codes, rules and regulations.
Failure to do so when necessary
could result in personal injury or
property damage from fire or
explosion, and area re-classification.
Vent line piping should comply with
local and regional codes and should
be as short as possible with adequate
inside diameter and few bends to re-
duce case pressure buildup.
In addition to remote venting of the
unit, ensure that all caps and covers
are correctly installed. Failure to do
so could result in personal injury or
property damage from fire or explo-
sion, and area re-classification.
The relay output constantly bleeds supply air into the
area under the cover. The vent opening at the back of
the housing should be left open to prevent pressure
buildup under the cover. If a remote vent is required,
the vent line must be as short as possible with a
minimum number of bends and elbows.
To connect a remote vent to DVC6010 SIS and
DVC6030 SIS digital valve controllers and
DVC6005 SIS base unit— remove the plastic vent
(key 52, figure 8-1). The vent connection is 3/8 NPT
internal. At a minimum, 12.7 mm (1/2-inch) tubing
should be used when installing a remote vent to
prevent excessive pressure from building up under the
cover.
To connect a remote vent to DVC6020 SIS digital
valve controllers— Replace the standard mounting
bracket (key 74, figure 8-2) with the vent-away bracket
(key 74). Install a pipe plug in the vent-away mounting
bracket (key 74). Mount the digital valve controller on
the actuator as described in the Installation section of
this manual. The vent connection is 3/8 NPT internal.
At a minimum, 12.7 mm (1/2-inch) tubing should be
used when installing a remote vent to prevent
excessive pressure from building up under the cover.
Electrical Connections
WARNING
To avoid personal injury resulting
from electrical shock, do not exceed
the maximum input voltage specified
in table 1-2 of this instruction manual,
or on the product nameplate. If the
input voltage specified differs, do not
exceed the lowest specified maximum
input voltage.
Personal injury or property damage
caused by fire or explosion may occur
if this connection is attempted in a
potentially explosive atmosphere or in
an area that has been classified as
hazardous. Confirm that area
classification and atmosphere
conditions permit the safe removal of
the terminal box cover before
proceeding.
Select wiring and/or cable glands that
are rated for the environment of use
(such as hazardous area, ingress
protection and temperature). Failure
to use properly rated wiring and/or
cable glands can result in personal
injury or property damage from fire or
explosion.
