Equipment Description
Groen Gas Heated Braising Pans provide a
stainless steel pan equipped with patented heat
transfer fins, burner/combustion chamber, handoperated tilting mechanism, thermostatic
controls, and hinged cover. The Braising Pan
serves as braising unit, griddle, fry pan, oven,
kettle, bain-marie, or food warmer and server,
and it can be adapted for use as a steamer.
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. 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, spring type actuator counter-balances
the cover to keep it in either the opened or
closed position. The cover opens to the back and
is hinged to the frame, so it moves independently
of the pan body.
The basic models differ in their mounting and
their ignition systems. Models HFP/1, HFP/1E,
HFP/2, and HFP/2E are mounted on an open-leg
frame fabricated from tubular stainless steel.
MW/HFP/1, MW/HFP/1E, MW/HFP/2, and
MW/HFP/2E are designed to be wall-mounted
with side support arms and a splashback.

C. Cooking
1. To simmer or slowly heat an item, set the
dial at 210 °F or lower. Put the cover down
to minimize moisture loss, or leave it up to
help dry or reduce the product. Set the
thermostat higher to cook or drive off
moisture faster. You may adjust the
thermostat to any setting to cook the item
exactly as required.
2. Leave the cover vent open to let excess
steam escape. For long simmering
operations, you may wish to close the vent
to retain moisture.
WARNING
STEAM CAN CAUSE BURNS. AVOID
ESCAPING STEAM WHEN RAISING COVER.
3. To check progress when the cover is
closed, lift the handle of the vent cover
slightly, and move it quickly to either side.
4. Standing to one side of the pan (to avoid
the steam that will be released) grasp the
nearer corner of the cover handle and raise
the cover. The cover will stay in the open
position until you push it down.
WARNING
ITEMS IN SAUCE OR MELTED FAT CAN
SLIDE FORWARD SUDDENLY DURING
TILTING AND SPLASH THE HOT LIQUID.
5. To pour or dump product, remove grease, or
assist cleaning, first raise the cover, then tilt
the pan forward by turning the tilting
handwheel. When you stop turning the
wheel, the pan body will hold its position.
6. To set the bell timer, turn knob clockwise
past five minutes, and set the desired time.
Sequence of Operation
The following "action-reaction" outline is provided to help the user understand how the equipment
functions.
A. Models with Standing Pilot
(Thermopile System)
When the operator presses down the knob
on the Combination Gas Control Valve and
turns it to "Pilot", gas is admitted to the pilot
burner. Depressing the knob in this position
overrides the automatic control, which
otherwise shuts off all gas supply when the
11
thermopile is cold. Lighting and maintaining
the pilot flame for sixty seconds heats the
thermopile to operating temperature, so the
thermopile begins to provide electric current
at 750 millivolts. Electricity from the
thermopile powers the control circuit and the
Combination Gas Control Valve. When the
thermopile begins operating at full capacity,
the knob may be released.
When the knob is turned to "ON", the
automatic valve for the main burner is able
to open. Setting the thermostat to call for
heat causes the thermostat to send a signal to
the valve, which opens and admits gas to the
main burner. Gas from the main burner is
ignited by the pilot flame. When the pan
reaches the set temperature, the thermostat
switch opens, stopping the signal to the main
burner valve an causing the valve to close.
When the pan cools below the set
temperature, the thermostat switch closes
and starts another heating cycle. On-off
cycling continues and maintains the pan at
the desired temperature.
B. Models with Hot Surface Ignition
When the operator sets the desired
temperature on the thermostat dial, the
thermostat switch closes and causes electric
current to heat the hot surface igniter. When
the coil gets hot enough to ignite gas, a
sensor built into the coil signals the
automatic gas control valve, which admits
gas to the burner. Gas flowing from the
burner is ignited by the hot surface igniter. A
separate sensor detects flame at the burner
and sends a signal that turns off electric
power to the hot surface igniter. If flame is
not sensed within 30 seconds, a timer shuts
off the gas flow.
OM -HFP
When the pan cools below the set temperature, the
thermostat switch closes and starts another heating
cycle. On-off cycling continues and maintains the
pan at the desired temperature.
C. All Models
The thermostat controls heating by
alternately calling for flames at the full
capacity of the main burner and then
signaling the control to shut the burner off
completely, because the control works in
this "all or nothing" way, the pan will
heat as fast as it can until it reaches the set
temperature, no matter what that
temperature is. Turning the thermostat
dial to a higher setting will cause heating
to continue longer, until the pan reaches
the higher temperature, but it cannot
make the pan heat any faster.
The pans are protected from overheating
by the high-limit thermostat. If the pan
temperature rises above 425°F, the highlimit thermostat causes the automatic gas
control valve to close. When the pan
cools, the thermostat automatically resets
and permits normal operation to continue.
Turning the tilting handwheel turns a worm
gear, which turns a gear wheel on one of the
trunnions that support the pan body. Turning
the gearwheel produces the tilting action.
When the pan reaches the set temperature,
the thermostat switch opens, stopping the
signal to the gas control valve and causing
the valve to close.
NOTE: Neither model will heat (operate) when
the braising pan has been tilted 10° or
more from horizontal.
12
1. Before any cleaning operation, shut off the
burner by turning the thermostat dial to "OFF". If
water or cleaning solution will be sprayed,
unplug the unit from the electric power source,
or shut off the power at the circuit breaker or
fuse panel.
Cleaning
2. Clean all food-contact surfaces soon after
use, before the pan has cooled completely. If
the unit is in continuous use, thoroughly clean
and sanitize both interior and exterior at least
once every 12 hours.
12
CAUTION
MOST CLEANERS ARE HARMFUL TO THE
SKIN, EYES, MUCOUS MEMBRANES AND
CLOTHING. PRECAUTIONS SHOULD BE
TAKEN TO WEAR RUBBER GLOVES,
GOGGLES OR FACE SHIELD AND
PROTECTIVE CLOTHING. CAREFULLY
READ THE WARNINGS AND FOLLOW THE
DIRECTIONS ON THE LABEL OF THE
CLEANER TO BE USED.
3. Scrape or rinse out large amounts of food
residues, then wash the inside of the pan body
with a mixture of hot water and soap or an
appropriate detergent, such as Mikro-Quat from
ECOLAB. Follow the detergent supplier's
recommendations on strength of the solution to
use. Rinse the pan thoroughly with hot water
and drain completely.
OM -HFP
your supplier of sanitizing products. Following
the supplier's instructions, apply the sanitizing
agent after the unit has been cleaned and
drained. Rinse off the sanitizer thoroughly.
NOTICE
NEVER LEAVE A CHLORINE SANITIZER IN
CONTACT WITH STAINLESS STEEL
SURFACES LONGER THAN 30 MINUTES.
LONGER CONTACT CAN CAUSE
CORROSION.
4. To remove materials stuck to the equipment,
use a brush, sponge, cloth, plastic or rubber
scraper, or plastic wool along with the detergent
or soap solution. To minimize the effort required
in washing, let the detergent solution sit in the
pan and soak into the residue, or heat the
detergent solution briefly in the pan. Do NOT
use any abrasive materials or metal implement
that might scratch the surface, because
scratches make the pan hard to clean and
provide places for bacteria to grow. Do NOT use
steel wool, which may leave particles imbedded
in the pan surface and cause eventual corrosion
and pitting.
5. As part of the daily cleaning program, clean
all external and internal surfaces that may have
been soiled. Remember to check such parts as
the underside of the cover, control console, etc.
6. Controls and the control console may be
cleaned with a damp cloth.
7. The exterior surface of the unit may be
polished with a recognized stainless steel

Maintenance
Your Braising Pan is designed to require
minimum maintenance, but certain parts may
need replacement after prolonged use. After
installation, no user adjustment should be
necessary. If a service need arises, only
authorized personnel should perform the work.
Service personnel should check the unit at least
once a year. This periodic maintenance should
include inspecting electrical wires and
connections, cleaning the inside of the control
References
console, and possible adjustment of the pilot
light. At least twice a year, grease the two
trunnion bearings.
A Service Log is provided with the warranty
information at the back of this manual. Each time
service is performed on your Groen equipment,
enter the date on which the work was done, what
was done, and who did it. Keep the manual with
the equipment for quick and easy reference.
