Flue Manifold Kits

(the “A” vent kit is included
with the appliance)

• Flame rod detects flame failure; results in auto shutdown to prevent escape
of gas

• Bi-metal switch, thermal fuse, and thermistor detect overheat condition;
results in auto shutdown

• 3 amp fuse protects against power surge; results in auto shutdown

• Abnormal spark at time of ignition results in auto shutdown

• Combustion fan purges any gas from the combustion chamber before

ignition

• Convection fan continues to run after burner shutdown to cool internal parts

• Child lock prevents inadvertent operation

• Appliance shuts down if room reaches 104° F (40° C)
