AUTOMATIC TURN DOWN TO PILOT (MOTOR ENDSTOP)
3 Hour No Communication Function
▪ The valve will turn to pilot ame if there is no communication
between handset and receiver for a 3 hour period. The re will
continue to function normally when communication is restored.
Receiver Overheating
The valve turns to pilot ame if the receiver temperature is higher
than 176 °F / 80 °C. If batteries are installed in the receiver the
temperature must not exceed 140 °F / 60 °C.
1 Hour Turn Down
(optional; requires specic handset)
▪ The valve will turn to pilot ame if there is no motor movement
over a 1 hour period.
NOTE: In Manual Mode the main burner can be turned back ON
after the receiver temperature is below 131 °F / 55 °C (with
batteries in receiver) or 176 °F / 80 °C (without batteries in
receiver). In Thermostatic Mode, the main burner turns
back ON automatically.
AUTOMATIC SHUT OFF
Countdown Timer
▪ At end of Countdown Time period, the re shuts off. The Count-
down Timer only works in Manual, Thermostatic, and Eco
Modes. Maximum Countdown Time is 9 hours and 50 minutes.
Low Battery Receiver
▪ With low battery power in the receiver the system shuts off the
re completely. This will not happen if the power supply is inter-
rupted.
On-Demand pilot
▪ CSA: 7 Day Shut-Off
CE: 5 Day Shut-Off
▪ This green feature eliminates gas energy consumption during
extended appliance inactivity. The system automatically extin-
guishes the pilot when the appliance is inactive for an extended
period of time. This feature helps the consumer realize cost
benets by automatically eliminating energy consumption dur-
ing non-heating months and limited use.

NOTE: Before the next ignition there is a 2 minute waiting pe-
riod. If the thermocouple is then still too hot, you will
hear a long beep.
