DESCRIPTION
Will be a Market Forge Model 3500 Gas Powered Convection Steam
Cooker. Will be integrally mounted on a cabinet base containing electrically powered steam boiler.
The 3500 will be of double-wall construction with 1” (25mm) thick insulation between cooking compartments and exterior walls, and will have
two 18 gauge stainless steel welded cooking compartments with coved
internal corners, and a 16 gauge stainless steel front panel.
Each cooking compartment on the 3500 has a positive slam action,
field-reversible door constructed of Type 304 stainless steel. Door
latches are spring loaded. The inner door gasket is a one-piece
NSF-approved silicone rubber gasket. The cooking compartment is
equipped with a door interlock (switch) that shuts off steam to the
cooking compartment when the door is opened. Factory installs units
with door opening from the right, see diagram on back. Each compartment will be equipped with a perforated steam inlet baffle positioned for
precise application of high velocity steam across the surface of food.

constant steam mode, an indicator light, steam inlet solenoid valve,
pressure relief valve, vacuum breaker, an automatic cold water condenser system, and a removable drip trough. Each compartment will
be independently and automatically controlled by setting the cooking
time on the 60-minute timer. At the end of cooking time, indicator light
will turn off and a continuous signal will sound. Signal is silenced by
returning the timer to the OFF position.
Stainless steel cabinet base will match other Market Forge stainless
steel equipment and enclose steam boiler. Base with stainless steel
frame will be equipped with 6” (152mm) stainless steel legs and adjustable bullet feet, reinforced stainless steel counter-top, and stainless
steel lift-off front cover and left front door.
The CSD-1 compliant steam boiler features an intermittent spark pilot
ignition and nickel plating. The steam boiler will be automatically filled
with water and brought to pressure when water and heat switches are
turned on and automatically drained under pressure when water and
heat switches are turned off. A cold water condenser will automatically
condense all exhausted steam before it is released from the cooker
and steam boiler drain. Also includes an ASSE approved backflow preventer, automatic water level control, low water cut-off, water strainer
and cathodic protector. For more boiler information see the M24GM36G spec sheet (14-0111).
The 6, 10 and 12 gallon steam jacketed kettle comes equipped with a
hot and cold faucet, sink with splash guard and a steam control valve.

altitude so that proper gas orifices can be provided.
The only available space to supply utilities to the gas boiler
is the 6” (152mm) space between the floor and the cabinet.
Allow 3” (76mm) space from side wall and 6” (152mm) from
rear wall if adjoining walls are combustible.
PVC & CPVC PIPE ARE NOT ACCEPTABLE MATERIALS

WATER SUPPLY
Good quality water feed is the responsibility of the owner. Water quality
must be within the following general guidelines.
TDS: 40-125 ppm Hardness: 35-100 ppm Chlorine: <0.2 ppm
Silica: <13 ppm Chlorides: <25 ppm
Chloramine: <0.2 ppm pH: 7.0 - 8.5
The best defense against poor water quality is a water treatment system
designed to meet your water quality conditions.
Appliance to be installed with backflow protection according to federal,
