Verify and document model and serial number of each oxygen removal vent installed:
Verify and document serial number of each oxygen removal vent control box installed:
Verify and document that the control box is properly installed:
If No, explain: _________________________________________________________________________ Verify and document wiring between the control box and the vent is properly installed:  Yes  No If No, explain: _________________________________________________________________________ Verify the control box timer is programmed properly:

3. Range is set to “10h”
4. Dial is set to “34”
Turn On the control box. Verify and document control box is operating properly:
If No, explain: _________________________________________________________________________ Determine the pressure setting of the backpressure regulator of oxygen removal vent.
1. The backpressure regulator setting must be below the cut-in or turn-on pressure of the nitrogen generator and above the low air alarm pressure of the fire sprinkler system.
Adjust the backpressure regulator setting on the oxygen removal vent:
1. Turn on the power switch to the control box and depress the “Vent” button.
2. Open and close the isolation ball valve on the oxygen removal vent to determine the pressure
setting of the backpressure regulator.
3. Pull the knob out from the regulator to adjust pressure setting. Turn the knob clockwise to raise
the pressure, counter-clockwise to lower the pressure.
4. Repeat process until desired pressure setting is achieved.
NOTE: Process can only be performed when fire sprinkler system is at normal operating pressure.
5. Once the desired pressure has been obtained on the backpressure regulator, push the knob onto
the regulator until it clicks into place.
Verify and document the backpressure regulator set point:
Verify and document the appropriate orifice in the oxygen removal vent: Verify and document isolation ball valve left in open position:
