ADJUSTMENTS
9. If manometer reads correctly, go to Step 13.
10. If manometer shows incorrect reading, remove cap from top of regulator.
11. With a screwdriver, rotate regulator adjustment screw "clockwise" to increase or "counter-clockwise" to decrease pressure
until manometer shows correct reading.
12. Put cap on regulator.
13. Turn all burner valves "OFF."
14. Turn main gas "OFF."
15. Remove manometer fitting.
16. Replace plug in manifold.
17. Replace panels ("A" suffix units) or filter ("D" suffix units).
18. Turn main gas "ON."
19. Light all pilots.
OVEN:
PILOT:
Take off lower front panel below oven by removing the two screws which secure it. Turn slotted screw adjacent to red
button on safety. Minimum pilot (approximately 3/4" long) should withstand a quick opening and closing of the oven door.
BURNER:
1. Obtain access to burner air shutter by removing the lower front panel below the oven. It is secured by two screws.
2. Turn valve or thermostat to FULL ON position.
3. Loosen the screw which holds the air shutter.
4. If flame is blowing or lifting off of the ports, close air shutter on front of burner until a stable flame is obtained.
5. If the flame is yellow tipping, open the air shutter until a stable flame is obtained.
6. Tighten the screw which holds the air shutter.
7. Replace the oven panel.
OVEN BYPASS FLAME (MINIMUM BURNER FLAME) ADJUSTMENT:
The pilot must be lit to make this adjustment.
1. Remove oven bottom so burner is visible.
2. Turn on oven valve.
3. Turn thermostat to 200 °F so main burner ignites.
4. With oven cool, turn dial clockwise slowly until bypass seat just snaps OFF.
5. Immediately reverse rotation and turn dial counterclockwise until bypass snaps open.
6. Remove dial.
7. With a screwdriver, turn "bypass flame adjuster" screw counterclockwise to increase the bypass flame or clockwise to
decrease the entire burner to a 1/8" minimum — 1/4" maximum stable flame. (See Fig. 1, Section 3, Page 3)
8. Replace dial.
NOTE: While making this adjustment, if the oven should become heated while the dial is set at a low range (below 350°F), the
bypass flame will shut off completely. If this occurs, turn dial counterclockwise slowly, until bypass gas snaps on. Then check
bypass adjustment as stated above.
