Equipment Description
Groen Gas Heated Braising Pans provide a
stainless steel pan equipped with patented heat
transfer fins, burner/combustion chamber, power
tilting mechanism, thermostatic controls, and
hinged cover. The Braising Pan can serve as
braising unit, griddle, fry pan, oven, kettle, bainmarie, 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.
The thermostat and tilting switch are contained
in a compact control console which is mounted
beside the pan body.
An electrically powered mechanism tilts the pan
forward. A three position switch on the front of
the control console gives the operator positive,
smooth-acting control of pan body tilt.
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 pan is mounted on a double-door cabinet
with friction latches. The cabinet exterior is
polished to a uniform m 4 finish, and accented on
the front with a color strip. A removable pan
support is provided as standard equipment.
CHFP/2 Models are distinguished from Model
CHFP/1 by several characteristics. CHFP/2 units
have higher firing rates, slightly wider pans, and a
manual override feature in the tilting mechanism.
Models of CHFP also differ in their ignition
systems.
CHFP/1 and CHFP/2 Models have a standing
flame pilot light that ignites the main burner..
Model CHFP/1/E has an electronic ignition
system which employs an intermittent spark.
CHFP/2/E also has an electronic ignition system,
but it uses a carborundum glow coil igniter.
Installation of any CHFP model requires
connection to gas and to 115 Volt electric power.

Sequence of Operation
The following "action-reaction" outline is provided to help users understand how the equipment works.
A. Models CHFP/1 and CHFP/2
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
thermopile is cold. Lighting and maintaining
the pilot flame for 60 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 and 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.
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.
C. Model CHFP/2/E with Coil Ignition
When the operator sets the desired
temperature on the thermostat dial, the
thermostat switch closes and causes electric
current to heat the Carborundum glow coil.
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 directly by the glow coil. A
separate sensor detects flame at the burner
and sends a signal that turns off electric
power to the coil. If flame is not sensed
within 30 seconds, a timer shuts off the gas
flow.
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. 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
B. Model CHFP/1/E with Spark Ignition
When the operator sets the desired
temperature on the thermostat dial, the
thermostat switch closes and sends a signal
which (1) starts the spark and (2) opens the
automatic valve for the pilot burner. The
spark ignites the pilot flame, which is
detected by the flame sensor probe. The
probe then sends a signal to shut off the
spark and open the automatic valve and
admit gas to the main burner. The pilot
flame ignites the main burner. If a pilot
flame is not detected within 30 seconds after
the spark starts, a lockout timer shuts down
the whole operation.
When the pan reaches the set temperature,
the thermostat switch opens, stopping the
signal to the gas control valve and causing
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” manner, 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 425ºF, the highlimit thermostat causes the automatic gas
control valve to close. When the pan cools,
the thermostat automatically resets and
10
Page 11
OM-CHFP
permits normal operation to continue.
The power tilt switch controls a reversible
motor which drives a ball screw mechanism.
When the switch is held in the raised
position, the mechanism raises the pan
body. The body rests on trunnions near its
front corners, so it tilts forward until the
switch is released or the body reaches its
vertical limit.
A tilt limit switch turns off gas flow to the
burner so that the unit will not heat (operate)
when the braising pan has been tilted 10º or
more from horizontal.
If the tilting motor gets too hot during
operation, an overheat protection switch will
open and stop the motor. When the motor
has cooled sufficiently, the switch will reset
automatically and permit tilting to begin
again. Such overheating will only occur if
the pan is continuously tilted up and down
through four or five cycles.
Cleaning
WARNING
KEEP WATER AND SOLUTIONS OUT OF CONTROLS AND BURNERS. NEVER SPRAY OR HOSE
THE CONTROL CONSOLE OR ANY ELECTRICAL CONNECTIONS.
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.
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.
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.
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 MikroQuat from ECOLAB. Follow the detergent
supplier's recommendations on strength of
the solution. Rinse the pan thoroughly with
hot water and drain completely.
4. 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
cleaner, such as "Zepper" from Zep
Manufacturing Co.
8. If the equipment needs to be sanitized, use a
sanitizing solution equivalent to one that
supplies 200 parts per million available
chlorine. Obtain advice on the best sanitizing
11
Page 12
OM-CHFP
agent from 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.
9. If there is difficulty removing mineral
deposits or a film left by hard water or food
residues, clean the pan thoroughly and then
use a deliming agent, like Lime-Away from
ECOLAB, in accordance with the
manufacturer's directions. Rinse and drain
the unit before further use.
10. If especially difficult cleaning problems
persist, contact your cleaning product
representative for assistance. The supplier
has a trained technical staff with laboratory
facilities to serve you.
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.
Don’t use metal implements or steel wool to
clean the braising pan.
Use a brush, cloth, sponge or other nonabrasive tool for cleaning.
WARNING
ELECTRIC POWER ALWAYS SHOULD BE
SHUT OFF BEFORE WORK IS DONE ON
INTERNAL COMPONENTS.
