4. Turn the HIGH SET knob counterclockwise until the high set point pivot just comes in contact with the flapper. The
pilot should have full output pressure (green indication on the optional output indicator).
5. Refer to table 5 and turn the HIGH SET knob clockwise to correspond to the desired set point value. For example,
with a 690 kPa (100 psig) Bourdon tube, turn the knob five revolutions for a desired high set point of 415 kPa
(60 psig).

1. Six dots per revolution.
6. Turn the LOW SET knob counterclockwise until the low set point pivot just comes in contact with the flapper,
moving the nozzle beam off the nozzle. The pilot should have zero output pressure (black indication on the optional
output indicator).
7. Refer to table 5 and turn the LOW SET knob clockwise to the desired set point value. For example, with a 690 kPa
(100 psig) Bourdon tube, turn the knob two revolutions for a desired low set point of 165 kPa (24 psig).
8. Lock the locking discs (key 69).
High‐Only Construction
1. Refer to the WARNING at the beginning of the Operating Information section. Make sure the Bourdon tube contains
no pressure.
2. Connect supply pressure to the pilot.
WARNING
Before continuing on with step 3, read this Warning:
Natural gas, if used as the supply medium, will seep from the unit into the surrounding atmosphere when the SUPPLY TEST
button is pushed. Personal injury or property damage may result from fire or explosion if preventative measures are not
taken, such as adequate ventilation and the removal of any ignition sources.
3. Turn on the supply pressure. To check that the supply pressure is on, press the SUPPLY TEST button in the cleanout
assembly (key 54) until a flow sound is heard.
4. Turn the LOW SET knob counterclockwise until it has reached the end of its travel.
5. Turn the HIGH SET knob counterclockwise until the high set point pivot just comes in contact with the flapper. The
pilot should have full output pressure (green indication on the optional output indicator).
6. Refer to table 5 and turn the HIGH SET knob clockwise to correspond to the desired set point value. For example,
with a 690 kPa (100 psig) Bourdon tube, turn the knob five revolutions for a desired high set point of 415 kPa (60
psig).
7. Lock the locking disc (key 69).
