Burner Flame Adjustment

Due to the difference of flow in nozzles even those of the same size it will be necessary to adjust the
pump pressure High and Low when changing nozzles. When making adjustments always start with the
high setting. (See Figure 4A)
1. Set Air Band at 1.25 to start.
2. Start the Radiant Heater and allow to run for 5 minutes.
3. Check the heat transfer disk on the front of the heater is it glowing bright orange or is it dull. This
can best be seen in a shady location and not in direct sun.
4. If it is bright orange check the side profile of the transfer disk and make sure no flames are coming
through the openings of the transfer disk.
5. If flames are coming through the face of the transfer disk the pressure is too high and will need to be
turned down.
6. If the heat transfer is dull orange the pressure will need to be turned up to achieve the desired glow.
7. Make sure the flames do not come through the face of the heat transfer disk.
Turning the adjustment screw clockwise will increase the fuel pressure. Turning the adjustment screw
counterclockwise will decrease the fuel pressure. The top screw changes the pressure for the low setting,
and the bottom changes it for the high setting (See Figure 4A).
