Groen CTDC-3-20-SG User Manual

Modular Equipment

Description

Unit shall be a Groen Model (2)CTDC/3-20-SG, with two
20 quart stainless steel tilting steam jacketed kettles, with
cabinet mounted gas steam boiler, per Bulletin 34Hd and
as follows:

Construction

Kettles shall be Type 304 stainless steel with solid one­piece welded construction, with tubular stainless steel
support arms. Rim shall be triple reinforced to resist
abuse, with a welded “Butterfly” shaped lip, for easy
pouring. Kettles shall have two operating handle lugs so
that handle can be attached on right or left side.
36” wide cabinet base shall have stainless steel frame,
top deck, double panel access doors, side and rear panels
and 6” legs. Front legs shall be adjustable bullet feet while
back legs shall have adjustable flanged feet. Cabinet
design and trim shall match other HyPLUS™ modular
equipment.

Finish

Cabinet base shall be finished to a #3 uniform finish.
Kettle exteriors shall be polished to a bright high buff
finish. Accent strip shall be matt finish polyester film
ensuring maximum ease in cleaning and maintaining an
attractive appearance.

ASME Code & UL Approval

Cabinet mounted steam generator shall be ASME Code
constructed and National Board registered for operation
up to 15 PSI. Kettles shall be coded and registered
for operation up to 55 PSI. Gas boiler is AGA design
certified.

Sanitation

Unit shall be designed and manufactured to meet NSF
known health department and sanitation codes and be
NSF listed.

Sinks/Faucet

Unit shall have one large flush mounted pouring sink
mounted in front of both kettles. Sink shall be piped to
common drain and provided with a removable anti-splash
screen. Unit comes standard with hot and cold water
faucet with swing spout.

Controls

Gas pressure boiler shall be provided with a gas control
valve, power-ON switch, reset light, start switch, exterior
mounted pressure gauge, water level sight glass, low
water sensor and pop safety valve. Kettle steam control
valves and hot and cold water faucets are front mounted
for easy access.

Performance Features

Unit will shut off if water level is too low or unit builds too
much pressure. When power switch is turned “off,” the
boiler automatically drains to reduce sediment build-up,
after water has cooled to 170ºF. Kettles shall operate
dependably at any steam pressure between 5 and 55
PSI.

Cabinet Base Steam Source

Unit shall have a gas heated cabinet mounted steam
boiler to provide approximately 10 PSI steam to the

model (2)CTDC/3-20-SG

kettles. ASME Code constructed and National Board
registered for operation up to 15 PSI. 200,000 BTU boiler
delivers to 120,000 BTU/hr into the product, is 60% efficient
and delivers 3.7 boiler horsepower. Unit comes with
standing pilot. Electronic ignition is available as an option.
Auxiliary manual drain valve to simplify maintenance is
also included.

Installation
Unit requires gas service via 1/2” NPT pipe or approved
equivalent. Unit requires 3/8” NPT hot and 1/2” NPT cold
water supply lines. Requires single free venting 11/4”
NPT drain for automatic and manual drain for kettles and
sink, and 115 Volt, 60 HZ single phase. 15 AMP electrical
service. Kettles are completely pre-piped to gas boiler.

Options

Electronic ignition for gas boiler
Lift-off covers for kettles
Basket insert for kettles
Basket inserts and brush kits for kettles.

Steam Source for Other Equipment

If additional equipment (steam kettle, etc.) is to be powered
by boiler, a power take-off valve is provided. To ensure
proper performance, boiler must be properly sized to meet
boiler horsepower requirements of kettles AND additional
equipment.

Water Supply Requirements

All water boiler systems are subject to contamination and
failure due to mineral content found in most water supplies.
To minimize service problems, a water treatment (softening)
system is recommended when water quality is found to
exceed limits stated below and in operator manual.
Recommended MINIMUM water quality standards are: total
dissolved solids (TDS) content should not exceed 30 parts
per million; and the water pH should be 7.0 or higher.

Origin of Manufacture

Kettle and cabinet mounted electric steam boiler shall be
made in the United States.
