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.

Ignition
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.
Models HFP/2E, and HFP/2 are mounted on an
open-leg frame fabricated from tubular stainless
steel.
Model HFP/2E has an ignition system that uses
electronic spark ignition. Optional model HFP/2
has a standing-flame pilot light that ignites the
main burner.

minutes or through several on-off cycles of
the burner.
CAUTION
DO NOT HEAT AN EMPTY PAN FOR MORE
THAN FIVE MINUTES AT A SETTING
HIGHER THAN 300oF. DAMAGE TO THE
PAN COULD RESULT.
C. Cooking
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.
1. To simmer or slowly heat an item, set the dial at
210oF or lower. Put the cover down to minimize
moisture loss, or leave it up to help dry or reduce
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.
Sequence of Operation
The following "action-reaction" outline is provided to help the user understand how the equipment functions.
A. Standard Models with Spark Ignition
1. When the power switch is turned on, it starts the
spark igniter and opens the automatic valve for the
pilot burner. The spark ignites a pilot flame, which
heats the sensor. The sensor then sends a signal
to turn off the spark. The flame thereafter acts as a
standing pilot until the power is turned off.
2. If the pilot flame is not sensed within 90 seconds
after spark begins, a timer shuts down the entire
operation. To attempt a second trial for ignition,
turn off the power switch. Check the gas supply
valves and wait five minutes before trying again by
switching power on. If there is still no pilot flame in
four tries, close all valves, turn off the power, and
contact an authorized Groen Service Agency.
3. When the operator sets a temperature on the
thermostat, it causes the automatic valve to admit
gas to the main burner, where it is ignited by the
pilot flame. When the braising pan reaches the
set temperature, the thermostat switch opens.
This stops the signal to the gas control valve and
shuts off gas to the main burner. The pilot flame
remains lit. When the pan cools below the set
temperature, the thermostat switch closes and
starts another cycle. On and off cycling continues
and maintains the pan at the desired temperature.
This action is indicated by the Heat indicator light.
