Once the valve begins to operate, the burner temperature will increase slowly (approximately 10
- 20 per second) to 250 0-270 0 F, (1 20 0-133 0 C) and then will start to increase more rapidly
(approximately 3 0-40 per second).
At approximately 3500 F, (1770C) the fan should begin to operate and cycle "on" for a few
seconds, then "off" for 20
—
30 seconds. At 7600 (4050C), the fan should remain on continuously.
If the fan does not come on, check for DC voltage on the printed circuit board at the motor
terminals. Be sure to observe the correct polarity. Continue checking for motor voltage over a
period of time sufficient to allow for several motor "on/off" cycles to have occurred. If the DC
voltage is present, replace the motor. If not present, replace the printed circuit board.
The burner temperature should stabilize at 10500 F, (5660 C) +/- 5%, 10 to 12 minutes after start.
In the unlikely event that the burner temperature reaches 1360 F (7380 C), the unit will
automatically shut down and two of the LED mode lights on the control panel will flash signaling
an overheat condition. Allow the unit to cool and then restart. If the overheat condition reoccurs,
replace the propane valve.
During start-up, if three of the LED mode lights on the control panel flash, this indicates that the
burner temperature will not increase above 760 degrees. If this should occur, switch the unit off
and allow it to cool. Then restart in the 24/7 mode. If the condition reoccurs, replace the burner
chamber.
