Surface Burner Adjustments - Viking DEVDSC305 Installation Manual

SURFACE BURNER ADJUSTMENTS

(For Open Surface Burners)
To gain access to the surface burner adjustments:
1. Remove the grates, burner caps, bowls and grate supports.
2. Located the air shutter (A) and loosen the screw (B) that holds the air shutter in place.
3. Replace grate support and burner bowls (this allows for correct air flow, as in normal use).
4. Light each burner by rotating the burner valve shaft (D) to high position.
5. With a proper flame height, adjust the air shutter (A) to obtain a blue flame with no yellow tipping that sits on the
burner at the burner ports.
a) Open the air shutter gap to eliminate yellow tipping.
b) Close the air shutter gap to prevent a noisy flame that lifts off the burner.
6. Turn the surface burners off.
7. Replace the drip tray.
8. Remove grate support and burner bowls.
9. Tighten the air shutter screw (B) being careful to not change the adjusted shutter gap.
10. Replace the grate supports, burner bowls, burner caps, and grates.
11. Turn the lighted burners to the low flame setting.
12. Insert a narrow, flat-blade screwdriver into the hollow shaft of the surface burner valve, and engage the slotted low
flame adjustment screw. The low flame should be a small flame that comes just to the top edge of the burner.
Rotate the adjusting screw (E) clockwise to lower the flame or counter clockwise to increase the flame. Turn the
burner off and relight several times, turning to the low position. The low flame should light at every port each
time. Readjust as needed.
