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.
This unit vents the supply medium into the surrounding atmosphere. When installing this unit in a non­hazardous
(non­classified) 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
re­classification.
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
re­classification.
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 explosion, and area re­classification.
3. If necessary, remove the plastic vent assembly (Figure 15) on the DPC2K and install a pipe­away vent line using at
least 12.7 mm (1/2­inch) diameter tubing. The vent line must be as short as possible with a minimum number of
bends and elbows to prevent back pressure build­up.
Note
Ensure that a bug screen is installed at the open end of the pipe away vent.
Ensure that vent opening in the pipe away vent is protected against the entrance of any foreign material that could plug it. Check
the vent periodically to be certain it is not plugged.
