OM-BPM-G 5
Groen gas-heated Eclipse Ergonomic Tilting Braising Pans provide a stainless steel
pan equipped with patented heat transfer fins, burner/combustion chamber, hand-
operated or electric powered tilting mechanism, thermostatic controls, and hinged
cover. The appliance serves as braising pan, griddle, fry pan, oven, kettle, bainmarie
and food warmer/server, can be adapted for use as a non-pressure steamer and can
be used to stir-fry, reheat and saute foods.
The pan body is made from heavy-duty stainless steel welded into one solid piece,
with a polished interior and exterior. A pouring lip is welded to the front wall. The
cooking surface is a stainless steel clad plate fitted with welded heat transfer
fins which assure uniform heat transfer over the entire surface. The gas burner/
combustion chamber supplies the heat.
An easily operated worm and gear mechanism tilts the pan and provides precise
control for pouring or dumping the contents of the pan. This hand-wheel controlled
mechanism is located in a stainless steel console to the right of the pan body. For
models with electric power tilt, a switch operates an electric motor that starts and
stops the pan tilt smoothly. To assist cleaning, the pan body can be tilted past the
vertical position. When the pan is tilted, the burners shut off automatically.
The thermostat provides automatic control of cooking temperature. Operating the
thermostat dial on the front of the control console turns the heat on or off and sets the
pan temperature.
A vented, heavy gauge, one-piece, stainless steel cover with a condensate drip shield
on the rear edge is standard on the Braising Pan. A fully enclosed, torsion bar type
counterbalance provides easy operation to open the cover and to maintain it open at
any position. The cover opens to the back and is hinged to the frame, so it moves
independently of the pan body.
The braising pan is mounted on an open-leg frame fabricated from tubular stainless steel
Models have an ignition system that uses electronic spark ignition.

Servicing & Conversion
1. Servicing
IMPORTANT: BEFORE ATTEMPTING ANY SERVICING, ENSURE THAT THE GAS
ISOLATING COCK IS TURNED OFF AND CANNOT BE INADVERTENTLY TURNED ON.
ENSURE ALSO THAT THE ELECTRICITY SUPPLY IS DISCONNECTED. AFTER ANY
SERVICING OR EXCHANGE OF GAS CARRYING COMPONENTS — ALWAYS CHECK
FOR GAS SOUNDNESS!
Notes:
1. When replacing wiring connections refer to the wiring diagram in the unit
or this manual.
2. When any threaded gas connection is disturbed for any reason, the
threads must be resealed with appropriate gas leak prevention sealant
that is suitable for the type of gas. Unified Brands/ Groen recommends gas
sealant compound such as Locktite® 243 or Unified Brands part number
122002.
A. After Servicing
a) Test for gas soundness as specified in IGE/UP1.
b) If leaks are found, disconnect the mating parts, clean the threads
and apply recommended sealant as specified above in Note 2. as
appropriate after any gas connection has been disturbed.
c) Check for correct operation as appropriate (see Installation,
Paragraph 5).
B. Regular Servicing Procedures
The following must be checked at regular intervals:
a) Burners Clean the burners periodically to maintain maximum
performance. Burners are best cleaned with a stiff bristle brush, or if
necessary with a wire brush. Take care not to damage the burner.
Clean the injector orifice with a wooden splinter or toothpick. Avoid
metal reamers, which may distort or increase the orifice size.
WARNING - Do not leave any wood splinter or bristles from brush in
the burner or injector. Fire could result.
b) Gears and Bearings: The gear housing has been fitted for proper
lubrication of moving parts. Since the gears do not run in oil, periodic
lubrication with grease is essential. Frequency of lubrication depends
on operating conditions, but should occur at least once every six
months. Groen recommends the use of a Number Two grade LGI
lithium grease. Add grease through the Zerk fittings on the gear
housing until grease flows out of the bearings around the trunnion
shaft. Place a liberal amount of grease on the gear to cover the arc
that is in contact with the worm gear.

the temperature settles at 190ºC (±5ºC). (Note: Thermostat may cycle
seven or eight times before oil temperature settles at 190ºC).
e) Replace control knob.
10. Removal of High Limit Thermostat (Turn gas and electricity mains off)
This device is set to shut off the flow of gas to the burners to prevent oil
temperature from exceeding 230ºC. Manual intervention is required to reset the
control in the event of a lockout.
A. To Reset: Remove the upper control box rear panel as described in
Paragraph 3-C. Push the reset button on the body of the high limit
thermostat.
B. To Check Operation: Operation of the high limit thermostat must be
checked regularly. Use the following procedure:
a) Remove the upper control box from panel as described in Paragraph
3.
b) Fill the pan with unused oil to the indicated mark. Place a
thermocouple or thermometer 25 mm below the oil surface in the
middle of the pan.
c) Ensure that the electrical power is off before continuing. Disconnect
the leads from the operating thermostat. Connect the leads together
using the terminal block. This effectively removes the operating
thermostat from the circuit. It may also be bypassed with a jumper
across the thermostat terminals.
d) Switch the unit back on and light the unit as described in the lighting
instructions. The burners will light and heat up the pan.
DO NOT LEAVE THE APPLIANCE DURING THIS TEST.
e) If the high limit thermostat is functioning correctly, the gas supply will
cut off as the temperature reaches 205 to 225ºC. Once the high limit
thermostat has tripped, switch off the mains electricity. Reconnect
the operating thermostat and replace all panels.
f) If the high limit thermostat switches, but not at the specified
temperatures, the thermostat requires replacement. Rejected
thermostats must be logged and returned.
g) To remove, see replacement procedures above. NOTE: After this test,
reconnect the regulating thermostat wires.
C. Calibration: The high limit thermostat is of the fixed type. Its calibration
point may not be adjusted.

B. Turn the toggle switch (Main Control Box) to the “ON” position. The power
lamp (green) (Main Control Box) will illuminate.
C. Turn the thermostat (Upper Control Box) to the desired setting.
D. Observe that the burners light by the lighting of the heat lamp (amber)
(Main Control Box) (approximately 10-15 seconds).
E. Should the unit fail to light, it will lock-out. Turn the unit off and wait for one
or two minutes before attempting to switch it on again.
F. Repeat steps B through E.
2. To Shut Down Braising Pan

3. Filling the Braising Pan
Using hot water and detergent, clean out the pan thoroughly prior to operation.
The pan should not be overfilled, and an allowance should always be made
for expansion and foaming of the food being cooked. The maximum fill level is
marked on the inner pan wall (See Fig. 14)
A. Do not leave the braising pan unattended when heating.
B. For shallow-frying, the depth of oil in the pan must never exceed the
maximum oil level mark on the inner pan wall. Avoid overheating the oil; do
not leave the braising pan unattended during use; and exercise care when
adding replenishment oil to a hot braising pan. Failure to observe care with
hot oil poses a serious risk of fire and personnel hazard.
4. Users’ Thermostat
Provides automatic control of the braising pan temperature at selected
temperatures up to a maximum of 190ºC.
5. Sequence of Operation
The following “sequence of operation” is provided to help the user understand
how the unit functions.
A. Switching the On/Off switch to the On position to start the appliance
causes the power lamp (green) to illuminate.
B. Turning the thermostat sends a signal to the ignition module.
C. The ignition module opens the pilot control valve which allows gas to go to
the pilot burner. It simultaneously starts a sparking sequence at the pilot.
D. The spark ignites the main pilot burner. Once this occurs, the sensing probe
detects the flame. This confirms that lighting has been successful.
E. After a short period of time the main control valve opens to full flow and
lights the burners.
F. The sparking/ignition sequence shuts off, and the “Heat” lamp (amber)
illuminates.
G. If, however, a pilot flame is not detected within 55 seconds, the ignition
module goes into lockout mode.
H. To restart the ignition sequence the ON/OFF switch must be set to OFF and
then back to ON.
