REPAIRING LEAKS IN STEAM
JACKETED KETTLE FITTINGS
If unit will not hold a vacuum the most likely cause is a leak
at one of the fittings.
Often, the easiest way to eliminate a leak is reseal the
suspect areas.
1.
Water Level Probe
Remove,clean threads, apply teflon thread sealant and
reinstall.
2.
Pressure Relief Valve
A
/ Inspect for signs of leaks. Replace if required.
CALIBRATING PROCEDURE
FREE AIR CALCULATION
1.
Insure the unit has a vacuum before you begin calibrating
procedures. If unit requires venting refer to KETTLE
VENTING INSTRUCTIONS.
2.
Set On-Off Switch/Temperature Control to "
10
" (Max.).
3.
Allow the unit to cycle twice.
4.
Check temperature of the inner kettle surface with a
digital surface thermometer.
5.
Temperature should be between 260°F and 265°F.
6.
Using a screw driver adjust
temperature by turning the
potentiometer on the Solid
State Temperature Control Box.
Turn very little. Turn clockwise
to INCREASES and counter-
clockwise to DECREASE
temperature.
7.
Allow the unit to cycle twice.
8.
Check temperature of the inner
kettle surface with a digital
surface thermometer.
9.
Repeat steps
4.
through
8.
until
unit is calibrated.

Insert drager pump tube 4" down the center
of the flue and take one sample each of
Carbon Dioxide (CO2) and Carbon
Monoxide (CO) and record results.
With results obtained for CO2 use chart to
determine dilution factor for gas type used.
Enter these numbers in the following formula
to determine the concentration of carbon
monoxide in an air free sample of flue gas.
Dilution Factor X CO (PPM) =
10,000
Result must not exceed 0.08% carbon monoxide.

Pressure Gauge
A
/ Inspect face of gauge. If it contains moisture on
the inside of face replace.
B
/ Check tightness of plumbing connection to
pressure Gauge.
4.
Sight Glass
A
/ Check tightness of sight glass.

/ Replace "O" ring if required.
5.
If unsuccessfull, repeat this process, replacing all
fittings and components.
