N Burner Component Adjust-
ments
1. Air Shutter Adjustments - May be required due to
local gas supply conditions. Loosen air shutter locking
screw on burner. Move shutter until burner flame is
without yellow.
2. Pilot Flame Adjustment - Remove thermostat knob.
With a thin bladed screwdriver, reach through bottom
of opening and turn pilot adjustor screw clockwise until
pilot flame starts to reduce. Then, turn pilot adjuster
screw clockwise until pilot flame starts to reduce.
Then, turn pilot adjustor screw counterclockwise until
pilot flame envelopes and is just above flame switch
sensing tube. Replace thermostat knob. NOTE:
Changing to propane gas will require reducing the
pilot flame to the above condition.
3. Thermostat By-Pass Adjustment - Allow toaster to
reach normal toasting heat. Place bun-toast switch to
the Toast position. Turn thermostat to #1 position (set
on Low with knobs so marked). Carefully remove
thermostat knob without disturbing setting. With a thin-
bladed screwdriver, reach through upper right of
opening and turn by-pass adjustment screw until
burner flame is steady across length of burner. Re-
place knob and reset thermostat and bun-toast switch
to original position.
0 Control Functions
Safety Solenoid Valve - Operates when both flame
switches close, to complete electrical circuit to coil,
which pulls plunger to open gas flow path to front burner
and control solenoid valve.
Pilot Flame Switches - Bulbs, positioned over the
pilots, are heated. Heat is transferred through sensing
tubes to close the series wired switches to complete
circuit and energize the safety solenoid valve coil.
Control Solenoid Valve - Coil is energized by bun-toast
switch placed in TOAST position which pulls plunger to
open gas flow path to the rear burner. In BUN position
coil is not energized, plunger shuts off gas flow.
On/Off Switch -The “ON” position closes the circuit to
the gearmotor, flame switches and bun-toast switch.
Bun-Toast Switch - Completes the electrical circuit to
the control solenoid valve coil when placed in the
TOAST position.
Shut-Off Valve - Manually opens or shuts off gas supply
line. When open, the gas flows through the pilot tubes.
Pressure Regulator - Maintains a 4” water column
pressure when natural gas supply exceeds that pres-
sure.
Thermostat – Regulates the gas flow to the burners.
Gas flow through the thermostat is controlled by the
temperature at the bulb. “Off” position shuts off all gas
flow except through the pilot tubes.
