DESCRiPTiON:

The Eco-Tech Plus Atmospheric Steamer from
Market Forge Industries is a stainless steel
atmospheric steamer with two cooking com­partments, each with an independent close­coupled atmospheric 42,000 BTU gas steam
generator.

Benets: The Eco-Tech Plus incorporates a
water management system that reduces the

amount of water used to condense generated
steam, resulting in substantial savings on en­ergy-related costs.

Industry First!: The ETP-10G is the only At­mospheric Twin Generator Steamer that comes

complete with a self contained water lter sys­tem. The built-in system eliminates the hassle
of where to put the lter and also provides a

warning indicator when it is time to change the

cartridges.

The Energy Star rating may qualify for rebates
in your state. Consult your local utility company
for details.

Construction: Eco-Tech Plus cooking com-
partments and cabinet are stainless steel with

unitized body construction. Cooking compart­ments have removable left, right, and rear body
panels. Each cooking compartment has a posi­tive, fully insulated, slam-action door construct­ed of Type 300 stainless steel. Door gasket is a
one-piece, NSF Approved silicone rubber gas­ket mounted on the inside of the door. Com­partments are equipped with door interlock
switches that automatically cut off power to the
gas valve when the doors are opened.

TECHNiCAL SPECiFiCATiONS:

Cooking Compartment: Each compartment is
provided with stainless steel pan support racks
and a stainless steel liner. The front edge of the

bottom compartment contains a condensate
drip trough that drains automatically to a water

management tempering tank.

Controls: Each compartment is individually

controlled by an on/off power switch and 60­minute electromechanical timer. At the end of
the cooking time, a continuous signal will sound

which can be silenced by returning the timer

to the off position. An exclusive mode selec­tor gives the operator the option of using each
cooking cavity as a holding cabinet.

Operation: Each compartment utilizes a pow-

erful close-coupled 42,000 BTU steam genera­tor that supplies steam to the cooking compart­ments. Generators are held in the “ready” mode
for quick response for heavy-demand situa­tions. Each generator is rated at 42,000 BTU.

Generator chambers are mounted at the rear

of the steamer cavity and close-coupled to the
steam compartment. Generators include as
standard a pilotless ignition system, automat­ic water level control, low-water cutoff, safety
relief valve, and preheat thermostat (190°F)
and high limit. Each generator includes an ac­cess port for Total Concept delimer/descaler.

iNSTALLATiON

SETTiNG iN PLACE:

The location of installation must be under an ex­haust hood, which will remove water vapor emit­ted when the cooker door is opened, and exhaust
combustion fumes. Level the unit in nal location by
turning the adjustable feet. Using the cabinet top as
a reference, obtain level adjustment left-to-right and
front-to-back.

MECHANiCAL CONNECTiONS:

All electrical and plumbing connections are located

on the rear panel of the unit. See ‘SERVICE CON­NECTIONS’ on page 4 for location of mechanical
connections.

iNSTALLATiON CODES AND STANDARDS:

Installation must conform with local codes, or in ab­sence of local codes, with the National Fuel Gas
Code - ANSI Z223.1/NFPA 54, or the Natural Gas
and Propane Installation Code, CSAB149.1 as ap­plicable.

The appliance and its individual shut off valve

1.
must be disconnected from the gas supply pip­ing system during any pressure testing of that
system at pressures in excess of ½ psi.

The appliance must be isolated from the gas

2.

supply piping system by closing its individual

manual shut off valve during any pressure test­ing of the gas supply piping system at test pres­sures equal to or less than ½ psi.

Electrical grounding must be provided in accor

dance with local codes, or in the absence of local
codes, with the National Electrical Code ANSI/NFPA
70, or the Canadian Electrical Code, CSA C22.2 as
applicable.

Ventilation must be provided in accordance with lo­cal codes, or in the absence of local codes, with
ANSI/NFPA 96 Standard for Ventilation and Fire
Protection of Commercial Cooking Operations.

WARNiNG: Electrical grounding instructions ­Units come equipped with a three-prong
(grounding) plug for your protection against
shock hazard and should be plugged directly
into a properly grounded three-prong recepta­cle. Do not cut or remove the grounding prong
from this plug. (120 VOLT UNITS ONLY).

COOKER CABiNET.

EXHAUST FANS AND CANOPiES:

Canopies are set over ranges, ovens, kettles, etc.,
for ventilation purposes. It is recommended that a
canopy extend 6” past the appliance and be located
6’ 6” from the oor. Filters should be installed at an
angle of 45 degrees or more with the horizontal. This
position prevents dripping of grease and facilitates
collecting the run-off grease in a drip pan, usually
installed with the lter. A strong exhaust fan tends to
create a vacuum in the room and may interfere with
burner performance or may extinguish pilot ames.
Makeup air openings approximately equal to the
fan area will relieve such vacuum. In case of unsat­isfactory performance on any appliance, check with
the exhaust fan in the “OFF” position.

WALL EXHAUST FAN:

Exhaust fans should be installed at least two feet
above the vent opening at the top of the unit.

CLEARANCES:

Adequate clearance must be provided in aisle and

at the side and back. Adequate clearances for air

openings into the combustion chamber must be

provided, as well as for serviceability. Use appli­ance on noncombustible surface only. Minimum
clearance from combustible and noncombustible
construction, 3” on left side, 8” on right side and 6”

GAS CONNECTiON:

1.

The Serial and Rating Plate on the unit indicates

the type of gas your unit is equipped to burn.
DO NOT connect to any other gas type.

A ¾” NPT line is provided at rear for the con-

2.
nection. Each compartment is equipped with an
internal pressure regulator which is set at 3.5”
W.C. manifold pressure for natural gas and 10”
W.C. for propane gas. Use c” pipe tap on the
burner manifold for checking pressure.

An adequate gas supply is imperative. Undersized
or low pressure lines will restrict the volume of gas
required for satisfactory performance. A steady
supply pressure, between 6” W.C. and 14” W.C.
for natural gas and 11” W.C. and 14” W.C. for pro­pane gas is recommended. With all units operating
simultaneously, the manifold pressure on all units
should not show any appreciable drop. Fluctua­tions of more that 25% on natural gas and 10% on
propane gas will create problems, affecting burner
operation. Contact your gas company for correct
supply line sizes.

PLUMBiNG CONNECTiONS:

NOTiCE: EQUiPMENT NOT iNSTALLED iN AC­CORDANCE TO THESE GUiDE LiNES MAY VOiD
THE WARRANTY.

WARNiNG: PLUMBiNG CONNECTiONS MUST
COMPLY WiTH APPLiCABLE SANiTARY, SAFE­TY AND PLUMBiNG CODES.

CAUTiON: AN OBSTRUCTED DRAiN CAN
CAUSE PERSONAL iNJURY OR PROPERTY
DAMAGE.

Two water lines are provided. Connect water sup­ply lines to the 3/8” copper tubes at the rear of the
steamer.

One line is for supply of water to the generator and
one for cold condensate water to condense live
steam entering the drain line.

DRAiN CONNECTiONS:

WARNiNG: AN OPEN GAP FLOOR DRAiN iS
REQUiRED iMMEDiATELY BELOW THE APPLi­ANCE DRAiN.

Purge the supply line to clean out any dust, dirt or
other foreign matter before connecting the line to
the unit. Use pipe joint compound which is suitable
for use with LP on all threaded connections.

Test pipe connections thoroughly for gas leaks.

WARNiNG: NEVER USE AN OPEN FLAME TO
CHECK FOR GAS LEAKS. CHECK ALL CON­NECTiONS FOR LEAKS USiNG SOAPY WATER
BEFORE USE.

ELECTRiCAL CONNECTiON:

120 VAC-60 Hz - Single Phase. Units with this elec­trical rating are factory supplied with a three-wire
cord and three-prong plug which ts any standard
120V, three-prong grounded receptacle. A separate
15 amp supply is needed for each unit.

CAUTiON: PVC OR CPVC ARE NOT ACCEPT­ABLE MATERiALS FOR DRAiNS.

WATER CONDiTiONiNG:

It is important that the water supplied to the gen-

erator be softened to no more than 2.0 grains of
hardness and have a pH of 7.0 to 8.5. This degree
of hardness can be easily obtained with the use of
a properly maintained water softener. The use of a

water meter will determine the water consumption

and when the water softener needs regeneration or
recharging. Failure to comply with these water con­dition standards may void the warranty.

Untreated water contains scale producing miner­als which can precipitate onto the surfaces in the

steam generator. Due to the temperatures in the
steam generator, the minerals can bake onto the
surfaces and components. This can result in early
component failure and reduced product life. Water
level probes become coated with scale. Scale may
bridge across the probe insulator from the metal ex-

tension which senses the water level in the steam

generator shell. Once this scale becomes wet, the

water level control is unable to maintain the proper

water level in the steam generator. STRAINERS
and FILTERS will NOT remove all minerals from
the water.
