Air Shutter Adjustment (oven burner only)
The quality of the flame can be changed by adjusting the air shutters. Factory setting on the air shutter is 0.40"
(10.6mm). (see figure 29)
Reduce the shutter opening if:
•
the flame appears unsteady
• is not burning all the way around
• is noisy like a small blow torch.
Increase the shutter opening if:
•
the flame has yellow tips
• there is no sharp blue cone
• soot appears on the bottom of cooking pans.
The air shutter is adjusted by loosening the locking screw and rotating the shutter to allow more or less air into the tube.
The centred position is usually about right. Tighten the screw, replace the assembly and check the flame pattern.
Oven Burner Assembly
The oven burner assembly is visible and accessible for servicing when the oven bottom panel is removed. The burner
assembly is made up of several components as shown below.
IMPORTANT
The thermocouple and igniter positioning is very
important to the operation of the oven. These two
items must be checked before putting the appli-
ance into operation. (see figure 31)
NOTE: Before putting the 7200 /9200 Gas Range into service, be
sure that all the setup procedures recommended in this manual
have been completed.
