STEP 7: TEST AND ADJUSTMENT

CAUTION

For Warranty coverage, Jenn-Air requires that burn- er adjustments be made by a qualified technician at the time of installation. Extreme care should be used when adjustments are made after installation.*

*Improper or lack of adjustments will void your warranty.

Oven and Griddle Burners

Check for the proper burner flame characteristics and adjust air shutters if necessary (see figures 13 - 14). Each valve and air shutter is individually tested and adjusted prior to shipment. Normally adjustment is not required, however, vibration during transit or variations in the local gas supply may make minor adjustments necessary.**

Burner flames should be blue and stable with no yellow tips, excessive noise or lifting of the flame from the burner. (Slight yellow - tipping is normal with LP gas). If any of these conditions exist, check that the air shutter or burner ports are not blocked. If this condition persists, adjust the air shutter as required.

If the flame is too yellow, indicating insufficient air, adjust the shutter counterclockwise to increase air inlet.

If the flame is noisy or tends to lift away from the burner, indicating too much air, turn the shutter clockwise to reduce air.

The oven burner flames should be approximately 1-1/2￿high. The griddle burner flames should be 1-1/2￿to 2￿ (see figure 13).

**The oven infra-red broiler burner has no air shutter and is not adjustable when used with natural gas. It is necessary to operate the oven broiler for 45 minutes to eliminate the harsh odor of the insulation binder. This must be done before using the range for the first time and with proper ventilation.
