INSTALLATION
Uncrate carefully. Report any hidden freight damage to
the freight company immediately.
Set unit in place. Be certain to maintain the following
minimum clearances to combustible construction. Side
“0” inches, back “4” inches at ue box. Level the unit
using a spirit level in all directions on the top of the kettle (lid up). Adjust the bottom foot on each leg to over-
come an uneven oor. Be certain to leave adequate
clearances for cleaning, maintenance and service. If
unit is also equipped with an optional water ll valve
it too must be connected with a exible water supply
tube, quick disconnect and strain relief.
Appliance location should have an exhaust system
provided directly above the appliance to exhaust
combustion generated by the gas burner. For use on
noncombustible oors. Minimum clearance from combustible and noncombustible constructions, sides “0”
inches, back “4” inches at ue box.
Clearance must be adequate in aisle and at the side
and back. Adequate clearances for air openings into
combustion chamber must be provided, as well as for
serviceability. All units must be installed in such a man-
ner that the ow of combustion and ventilation are not
obstructed. Provisions for an adequate air supply must
also be provided. Do not obstruct the lower front or left
side of the unit, as combustive air enters through these
areas.
DESCRIPTION: The kettle has double-wall construction of 300 series stainless steel forming a steam jacket
around the lower 2/3 of the kettle. The jacket enclosure
contains factory sealed water and antifreeze. The kettle
exterior is fully insulated. The bottom of the kettle is a
hemispherical design for superior heat circulation. The
recessed control panel is located on the front right side
of the unit in full view of the operator. Standard controls
include direct immersion thermostat, water sight glass,
cooking light, pressure gauge and electronic ignition
with ignition indicator light. Safety features include low
water cutoff with indicator light, pressure switch, pressure relief valve and a 100% safety gas shut off valve.
The kettle pivots on trunnions connected to the gear
and control consoles. The worm and gear tilting mechanism allows the kettle to tilt forward to a full 90° for
complete draining. The tilt mechanism is self locking
for positive stop action. The consoles are drip proof,
stainless steel clad and are supported on all welded 1
5/8” (41mm) diameter stainless steel legs with anged
feet.
kettle is A.S.M.E. code stamped for operation to 50
PSI. Temperature range from 150° F to 285° F.

MAINTENANCE
PERIODIC MAINTENANCE
NOTICE: As a safety precaution, disconnect the power
supply during cleaning or servicing.
CLEANING
For easier cleaning add cold water to the kettle immediately after removing contents and let soak.
Wash exposed cleanable areas daily. To remove normal dirt, grease or product residue from stainless steel,
use ordinary soap and water applied with a sponge
or cloth. Dry thoroughly with a clean cloth. Never use
vinegar or any corrosion cleaner. Never, use ordinary
steel wool, wire brush or steel scouring pads. Never
use cleaning solvents with a hydrocarbon base on
control panel. Blower wheel inlet screen and motor air
vent should be cleansed if an accumulation of dust or
lint is obvious.
At least twice a year the unit venting system should be
examined and cleaned. At least twice a year have an
authorized Service Person clean and adjust the unit for
maximum performance.
RE-ESTABLISHING VACUUM
With the kettle completely cold a vacuum of 25 to 30
inches mercury column should be maintained as indicated by the pressure gauge on the front control
panel. If at any time the vacuum is less than 25 inches
M.C. the vacuum should be re-established. With the
kettle empty turn the thermostat knob to the highest
temperature. When the pressure gauge reaches 2.0
PSI turn thermostat off, open the pressure relief valve
until manometer reads 1 PSI then sharply release it.
This should remove the air and any loss in performance should return. Should the kettle fail to maintain
a vacuum after repeated attempts to establish it further
checks should be made to see if the pressure relief
valve is leaking or if there are any leaks in the pressure
relief valve piping, copper lines going to the pressure
switch, pressure gauge or thermostat tting.
ADJUSTMENTS
THERMOSTAT: The thermostat adjustment should not
be changed. Check the following before changing the
thermostat.
With kettle cold, the pressure on the pressure
1.
gauge should read 25 to 30 inches mercury column vacuum. If not, see “Re-establishing Vacuum”
above.
The pressure switch is .not set too high or too
2.
low and causing the out of adjustment condition.
A voltmeter should be used by a properly trained
servicemen to determine if the pressure switch or
thermostat is actually cycling the burners. If the
pressure switch is found to be the problem. See
“Pressure Switch” below.
PRESSURE SWITCH: The pressure switch should not
be adjusted until it is determined to be the cause of an
operating pressure difculty. See “thermostat” section
to determine if the source of difculty is the pressure
switch or thermostat, The major difculties caused by
pressure switch miss-adjustment are:
Pressure relief valve opening, especially on pre-
1.
heat from a cold start to 285oF (pressure switch
set too high).
Pressure in kettle is to low and burners are being
2.
shut down by pressure switch (not thermostat).
The pressure switch is preset for proper operation
from the factory. It is adjusted to the maximum pressure which will prevent the pressure relief valve from
opening. This setting will be slightly different on different kettles due to variations in the pressure relief
valves. During preheat to the maximum thermostat
setting (285oF), from either a cold condition or a lower
temperature setting, the temperature may overshoot
the thermostat setting and be shut down by the pressure switch. This is normal, however, after the kettle
has cycled several times (empty) the thermostat will
begin cycling the unit. .
TO ADJUST PRESSURE SWITCH:
With the kettle empty and completely cold, turn
1.
kettle on and set thermostat to maximum setting
(285oF).
Pressure in kettle (read pressure gauge on front
2.
panel) should reach a maximum pressure of 40
PSI and pressure relief valve should not open.
Kettle pressure may rise 3 or 4 PSI even afterburners shut down.
Relief valve should not open when kettle pressure
3.
is 40 PSI pressure switch setting is satisfactory.
If relief valve opens, reduce setting on pressure
4.
switch, cool kettle completely by running cold water through it and repeat this procedure.
If pressure in kettle is below 40 psi increase set-
5.
ting of pressure switch, cool kettle completely by
running cold water through it and repeat this procedure.
To obtain access to the pressure switch the front
6.
panel must be removed. Remove the screws on
either side of the panel. Be sure to support the
panel to avoid excessive strain on the wiring.
To increase the pressure switch setting turn the
7.
white ribbed knob clockwise; to decrease turn it
counterclockwise. Use the centre of the black ring
as an indicator.
