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, 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.
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.
