Low Battery Receiver
 When the receiver battery power is low, the GV60 system shuts off the fire and pilot.
Five Day Shut Off
(CSA version)
 The system shuts off the fire and pilot if there is no change in flame height for 5 days.
Backup Batteries
 If the mains power should fail, the receiver automatically goes to battery power for all functions except the light and fan.
Second Thermocouple Shut Off
 Second Thermocouple Option: The system shuts off the fire when the main burner does not completely ignite
approximately 20 seconds after ignition or after pushing the large flame button.
NOTE: If there is a failure due to the second thermocouple not receiving a signal, there is a 2-minute waiting period prior to
the next ignition sequence. This is to allow for the gas in the system to dissipate.

Advanced Features - Standard
Display
 Large temperature indicator
 Multilevel energy indicator (4 bars)
6-hour No Communication Turn Down (CE, CSA)
 Manual Mode/Temperature/Timer Mode: The valve will turn to pilot flame if the
batteries in the handset are low or if the handset is out of communication range
for a 6-hour period.
6-hour No Motor Movement (CSA)
 Manual Mode/Temperature/Timer Mode: The valve will turn to pilot flame if there is
no change in burner flame height for a 6-hour period. In Temperature/Timer Mode, if
the ambient room temperature changes, the burner flame height will adjust
automatically to maintain set temperature, and the fire will continue to function
normally.

burner will come back on only when the temperature is below 140°F (60°C).
1-hour Turn Down for Bedroom Fires
 Valve turns to pilot flame if there is no change in burner flame height over
a 1-hour period.

Adjusting the Pressure Regulator
(for Vented Units Only)
Remove small plug to access
the adjustment screw.
Turn the adjustment screw to set required burner pressure
(high fire). Pressure is increased by turning clockwise or
decreased by turning counterclockwise. This adjustment is
required for fuel conversions.

Convertible regulators are designed to deliver either of two fixed outlet pressures for Natural Gas (NG) or LP Gas. To
change from one gas to the other, turn the conversion plug counter clockwise and remove it from the valve. Unsnap
and remove the plastic part of the conversion plug, rotate it 180°, and then slide it back onto the conversion plug until
it snaps. Insert the conversion plug into the valve and turn it clockwise until it bottoms out.
