Thermostatic Flame Modulation
This control can perform Main Flame Modulation using the Thermostat. The control will shut the
unit off when the room temperature reaches 2°above set temperature. The Thermostat will
automatically modulate the main flame as follows:
2°above set temperature OFF
1°above set temperature Flame Level 1
at set temperature Flame Level 2
1°below set temperature Flame Level 3
2°below set temperature Flame Level 4
3°below set temperature Flame Level 5
4°below set temperature Flame Level 6
5°below set temperature Flame Level 7
Manual Flame Modulation – Main Flame
To change the Flame Level manually, press the FLAME MAIN button. The current level will
show in the MAIN box on the LCD screen.
Press the UP or DOWN button to change the Flame Level.
When the unit is turned on, whether in Manual, Thermostatic, or Program Mode, the Main Flame
will automatically ignite at the High (7) setting. After 5 seconds, the flame will default to the
previous setting.
Manual Flame Modulation – Rear Flame
To change the Rear Flame Level manually, press the FLAME REAR button. The current level
will show in the REAR box on the LCD screen.
Press the UP or DOWN button to change the Rear Flame Level.
When the unit is turned on, whether in Manual, Thermostatic, or Program Mode, the Rear Flame
will automatically ignite at the High (3) setting. After 5 seconds, the flame will default to the
previous setting.
Note:
The rear flame level is dependant upon gas flow through the main valve. Therefore, if the Main
Flame setting is less than high, the rear flame gas flow will be reduced proportionately at all
levels.
Fan Control
The unit must be ON to operate the Fan.
The Fan will turn on after 5 minutes of operation. Once the Fan comes on, it can be controlled
using the FAN button.
