GAS
ENSURE THE GAS SUPPLY MATCHES THE KETTLE'S
REQUIREMENTS AS STATED ON THE RATING PLATE.
Installation must conform, with local codes or in the absence of local
codes, with the National Fuel Gas Code ANSI Z223.1/NFPA 54, or the
Natural Gas and Propane Installation Code, CSA B149.1.
The appliance must be isolated from the gas supply piping system
by closing its individual manual shut-off valve during any pressure
testing of the gas supply piping system at test pressures equal to or
less than 1/2 psi (3.45 kPa).
It is recommended that a sediment trap (drip leg) be installed in the
gas supply line. If the gas pressure exceeds 1/2 psi (3.45 kPa) water
column, a pressure regulator must be installed, to provide a
maximum of 1/2 psi (3.45 kPa) water column gas pressure to the gas
control valve.
Use a gas pipe joint compound which is resistant to L.P. gas. Test all
pipe joints for leaks.
ELECTRICAL
ENSURE THE ELECTRICAL SUPPLY MATCHES THE KETTLE'S
REQUIREMENTS AS STATED ON THE RATING LABEL.
Electrical installation must be in accordance with local codes and/or
the National Electric Code ANSI/NFPA 70-1990 (USA) or the
Canadian Electrical Code CSA Standard C22.1 (Canada). The kettle
must be electrically grounded by the installer.
A separate fused disconnect switch must be supplied and installed in
the high voltage electrical supply line.
A wiring diagram is affixed to the top of component box cover.
Remove the right side panel to access component box. Feed the
wiring through the cut-out in the bottom of the console using liquid
tight conduit.
For proper electrical connections of units with remote controls please
refer to the wiring diagram included with the unit. For tilting units
wiring package is attached under the gearbox cover. For stationary
units it is inside the Inverter housing on the left side of the kettle. For
units with Remote consoles it is inside the console box.
WATER
The sealed jacket of the gas-fired kettle is precharged with the
correct amount of a water-based formula, and therefore, no water
connection is required to the kettle jacket. The kettle can be
equipped with optional hot and cold water taps, requiring 1/2"
copper tubing as supply lines.
INSTALLATION & OPERATION CHECKS
Although the kettle has been thoroughly tested before leaving the
factory, the installer is responsible for ensuring the proper operation
of kettle once installed.
1. Before turning the kettle on, read the vacuum/pressure gauge.
The gauge's needle should be in the green zone. If the needle is
in the "VENT AIR" zone, follow Kettle Venting Instructions.
2. Unit has been thoroughly checked for gas leaks at the factory
however the installer should check all connections for any leaks
which may have resulted from shipping or installation.
3. Supply power to the kettle by placing the fused disconnect
switch to the "ON" position.
4. Open gas shut-off valve to turn on main gas supply.
5. Turn the temperature control knob to "1" (Min.). The green LED
light should remain lit, indicating the burner is lit, until the set
temperature is reached. Then the green light will cycle on and
off, indicating the burner is cycling on and off to maintain
temperature.
6. Tilt the kettle forward. After a few seconds the red "LOW WATER"
light should be lit when the kettle is in a tilted position. This light
indicates that the burner has automatically been shut off by the
kettle's safety circuit. This is a normal condition when the kettle is
in a tilted position.
7. Raise the kettle to the upright position. The red "LOW WATER"
light should go out when the kettle is upright.
8. Turn the temperature control knob to "10" (Max.) and allow the
kettle to preheat. The green light should remain on until the set
temperature is reached. Then the green light will cycle ON and
OFF, indicating the burner is cycling ON and OFF to maintain
temperature.
9. Check carbon monoxide is less than 0.08 percent in an air-free
sample of the flue gases. See FREE AIR CALCULATION procedure
in “Maintenance Procedures & Parts Lists” manual.
10.
After installation the kettle must be thoroughly cleaned and
sanitized prior to cooking.
KETTLE
VENTING
INSTRUCTIONS
1. Remove Access Panel from back of
main kettle console.
2. Turn kettle ON and set temperature
control to
10 , heat the empty kettle until
unit cycles off.
3. Vent kettle by pulling Valve Ring eight to
fifteen times, holding valve open for
two seconds each time.
NOTE : If unit cycles ON, stop venting
and wait for kettle to cycle OFF before
continuing.
4. Turn kettle OFF. Add cold water to kettle
until its surface temperature is below
100°F. The pressure gauge needle
should be in the green zone, indicating
a vacuum in the kettle’s jacket.
5. If needle is in the green zone then
venting was successful. If not repeat
procedure.
