STEP 6: BACKGUARD INSTALLATION
The backguard must be installed when there is less than
a12² clearance between combustibles and the back of
the range above the cooking surface (see Figure 3B).
RANGE BACKGUARD KITS
HIGH SHELF:
(22²) PRAG3022 - 30²
PRAG3622 - 36²
PRAG4822 - 48²
LOW SHELF:
(12²) PRAG3612 - 36²
PRAG4812 - 48²
The backguard is inserted, as shown in Figure 12, into the
guide channels on the back of the range. Secure the
backguard with the (4) sheet metal screws provided.

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 1-1/2²
high. The griddle burner flames should be 1-1/2² to 2²
(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.
