CALIBRATING PROCEDURE
FREE AIR CALCULATION
1.
Ensure 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.
