Vent Connection
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
federal 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
insider diameter and few bends to
reduce case pressure buildup.
In addition to remote venting of the
unit, ensure that all caps and covers are
