TO TURN OFF GAS TO APPLIANCE
1. Turn off the "ON/OFF" rocker switch and/or thermostat (if
installed) to its lowest setting.
2. Turn off electric power to the appliance if service is to
be performed.
3. Push in gas control knob slightly and turn clockwise
to "OFF." Do not force.
This appliance needs fresh air for safe operation and
must be installed so there are provisions for adequate
combustion and ventilation air.
WARNING: Improper installation, adjustment, alteration,
service, or maintenance can cause injury or property dam-
age. For assistance or additional information, consult a
qualified installer, service agency, or your gas supplier.
Operation of this appliance when not connected to a prop-
erly installed and maintained venting system can result in
carbon monoxide (CO) poisoning and possible death.
SHUTDOWN PROCEDURE
To turn off the burner, turn the rocker switch to "OFF" or
adjust the thermostat (if installed) to a setting below room
temperature. The pilot will remain lit for future burner igni-
tion. For complete shutdown, see "TO TURN OFF GAS TO
APPLIANCE" above.
Flame Color & Behavior
Your Vision™ gas stove is designed for maximum heating
efficiency. Therefore, upon lighting of the main burner the
flames will be semi-transparent or “bluish.” After 10-20
minutes of operation the logs will heat up and the flames
will become a yellow/orange color.
Adjusting the stove to cause the flames to turn orange sooner
may result in poor combustion, sooting, and a hazardous
situation. See the drawing to the right showing proper flame
appearance.
