Further information can be obtained by referring to the U.S.A. National Fire
Protection Associations NFPA96 regulations. These standards have also been
adopted by the National Building Code in Canada.

rating label which is adhered to the unit.
Allow 12” minimum on right for service.
- Position the unit in it’s permanent location, and level the unit by turning the adjustable feet.
- Once positioned and leveled, permanently secure the unit’s flanged feet to the floor using 5/16″ lag bolts and floor anchors (supplied by the installer). Three bolts are required to secure each of the flanged feet.
- Seal joints of flanged feet with a silicone sealant.
- Remove any protective material covering the stainless steel panels.
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 and its individual shut-off valve must be disconnected from the
gas supply piping system during any pressure testing of that system at test
pressures in excess of 1/2 psi (3.45 kPa).
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.
- Removed supplied manual shut-off valve and establish mounting location.
- Add union and piping as required.
- Connect the gas line to the manual shut-off valve.
ELECTRICAL
ENSURE THE ELECTRICAL SUPPLY MATCHES THE KETTLE’S REQUIREMENTS AS STATED ON
THE RATING LABEL.
A cord and plug are supplied with the unit. Simply plug the unit into any
grounded outlet rated for a minimum of 10 amps.
The kettle must be electrically installed and grounded in accordance with
local codes, or in the absence of local codes, with National Electrical Code,
ANSI/NFPA 70 (USA) or the Canadian Electrical Code, CSA C22.2, (Canada).
Standard supply voltage is 115 volts A.C., however, optional A.C. voltages can
be supplied on special order. A separate fused disconnect switch must be
supplied and installed in the high voltage electrical supply line.
The wiring diagram is located under the cover of electrical box inside the
back console.
WARNING: Electrical Grounding Instructions.
This unit is equipped with a three-prong (grounding) plug for your protection
against shock hazard and should be plugged directly into a properly grounded
three-prong receptacle. Do not cut or remove the grounding prong from this
plug.
NOTE: Units are tested on a in-house ground fault system. However, there is no guarantee the unit will work on all ground fault systems. If you are having problems you can hard wire the unit.
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.
CLEANING
After installation the kettle must be thoroughly cleaned and sanitized prior
to cooking.
INSTALLATION 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.
-
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 air venting procedure. -
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.
-
Supply power to the kettle by placing the fused disconnect switch to the “ON” position.
-
Open gas shut-off valve to turn on main gas supply.
-
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.
-
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. -
Raise the kettle to the upright position. The red “LOW WATER” light should go out when the kettle is upright.
-
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.
-
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.
