CONTROLLER SETUP
Flame Strength
Primary Function:

The Flame Strength button displays the current flame strength value for the Flame Rod and temperature
for the Thermocouple.

To check flame strength when using a Flame Rod.
1. Press the flame strength button.

When no flame is present, the value will be above 500.

When flame is present the value will be below 6.

To check flame strength when using a Thermocouple.
1. Press the flame strength button.

On a initial start-up when the thermocouple is cold the temperature will read 70.

When the flame is not present, the system observes a decrease in temperature to sense a
flame out.

When the flame is present, the system observes an increase in temperature to sense a flame.
Secondary Function:

The Flame Strength button displays the Safety Thermocouple temperature shutdown setting when pressed
and held for 5 seconds.

To set or change the Safety Thermocouple temperature shutdown, follow these steps:
1. Press the Flame Strength button to view current thermocouple temperature.
2. Unlock the system by pressing and holding the up arrow for 5 seconds until a series of zeros
appear.
3. Press and hold the Flame Strength button and use the up and down arrow buttons to adjust to
desired temperature.
NOTE: The Safety Thermocouple factory setting: 300°F
The Safety Thermocouple range: 40°F — 2400°F
