Equipment Description
Groen Gas Heated Braising Pans provide a
stainless steel pan equipped with patented heat
transfer fins, burner/combustion chamber, hand-
operated 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.
Models HFP/1, HFP/2, MW/HFP/1, and
MW/HFP/2 have a standing-flame pilot light that
ignites the main burner. Models HFP/1E,
HFP/2E, MW/HFP/1E, and MW/HFP/2E have
ignition systems that use a hot surface igniter.
Options available with the listed models are:
1. Fill faucet with swing spout.
2. Caster mounting kit.
3. Fold-down work tray (pan support) mounted on
left or right side.
4. 2" Tangent draw-off
5. Model REJ Steamer Insert set.
6. Steamer pan Carrier.
7. Quick gas disconnect with restraining cable.
