5.)
Check to see that your gas reading is NOT MORE than three or four pounds of
pressure. Too much pressure will also prohibit lighting.
6.)
Check for spark at pilot burner:
b.) Is spark electrode hooked up? (This is the red nipple attached to the control
module.)
c.) Is the burner grounded on the coil? If it is then re-position coil away from
the burner.
d.) Is the spark ceramic cracked or chipped or cable damaged? If so, replace the
pilot assembly.
e.) Check gap to see if it is 0.1”. The spark gas is part of the pilot assembly
housing.
f.) If there is still no spark, replace the control module.
7.)
Make sure your burner system in unit is not wet.
8.)
Check to see if pilot is lit.
CAUTION: NEVER LOOK DOWN THE CYLINDER TO CHECK FOR THE PILOT
a. To check this, put a mirror under the body of the machine to
view the burner area. If there is a pilot, go to step 10
.
b. Check for a clogged pilot orifice.
a. Remove the thin coupler line and unscrew the pilot
orifice from the pilot assembly. Two very little holes should be clear
upon inspection up to a good light source. If not, then replace.
9a.) Check for supply of gas, if there isn’t any then get propane tank filled or check for
obstructions in gas lines or regulator. Fuel pressure gauge should never be run
higher than 6 lbs. of fuel pressure, the burner can become flooded and not allow
ignition.
9b.) Check to see if pilot solenoid is opening by connecting the wires to an alternate 24-
volt source. (For example, lines three through six on the terminal strip. Touch one
wire to this source and the other wire to a ground.) You should hear the “click” or
the pilot solenoid opening. If you don’t, then replace the solenoid.
10.) If there is a pilot:
a.) Check to see if the flame sensor is red hot, if not, clean or replace the pilot
orifice.
b.) Check if the flame sensor wire is not damaged and hooked up properly. Replace
or go on to “c”.
c.) Check for cracked flame sensor. Removing the flame sensor will give you an
accurate view of any chips or cracks to the flame sensor. If you find these, then
replace the sensor. Tighten just slightly past hand tight.
