Test the safety valve at least twice
monthly.
The pressure gauge should show a vacuum
of 20 to 30 inches when the kettle is cold.
Maintenance
NOTICE: Contact Groen or an authorized Groen representative when repairs are required.
1. Periodic Maintenance
A Maintenance & Service Log is provided at
the back of this manual with the warranty
information. Each time maintenance is
performed on your Groen kettle, enter the
date on which the work was done, what was
done, and who did it. Keep this manual on
file and available for operators to use.
Periodic inspection will minimize equipment
down time and increase the efficiency of
operation. The following points should be
checked:
a. Check the pressure/vacuum gauge
every day. The gauge should show a
vacuum of 20 to 30 inches, when the
kettle is cold. If it does not, see “Jacket
Vacuum” below.
b. Also check the jacket water level every
day. It should be
between the marks on
the gauge glass. If the
level is low, see “Jacket
Filling and Water
Treatment” on page 13.
c. Test the safety valve at
least twice each month.
Test the valve with the
kettle operating at five
psi, by pulling up the
test valve chain for at
least 5 seconds. Then
release the lever and let
the valve snap shut. If
the valve does not
activate, or there is no
evidence of discharge,
or the valve leaks, stop using the kettle and
contact a qualified Groen service representative.
WARNING
WHEN TESTING, AVOID ANY EXPOSURE
TO THE STEAM BLOWING OUT OF THE
SAFETY VALVE. DIRECT CONTACT
COULD RESULT IN SEVERE BURNS.
d. Keep the primary air shutter of the
burner gas jets free of dust and lint.
e. The pilot flame should be blue, and
should envelop about ½ inch of the
flame sensor tip.
f. Maintain electrical wire and connections
in good condition.
g. Keep the inside of the control console
clean and dry.
h. Keep the burner ports clean.
i. Keep the burner shield and adjacent
parts clean.
