2.0 INTRODUCTION

DESCRIPTION

The ETP-5G and ETP-10G are gas fired pressureless steam cookers. The cooking
compartments are equipped with a three-piece door with inner gasket plate isolated from the
exterior surface. Door latch operates by slam action for positive sealing of the door. Operating
controls are displayed on a front-mounted panel and include indicator lights for ignition, ready
and cooking modes, a timer to set cook times and a selectable hold cycle to keep food warm
once cooked, a temperature display to monitor cavity temperature, and an illuminated
ON/OFF/DELIME switch. The ETP-5G is equipped with one generator, the ETP-10G with two.
Each stainless steel steam generator operates “0" psi (0 kPa) and is rated at 42,000 BTUH.

BASIC FUNCTIONING

The cooker is ready for operation when the READY light comes on.
At the end of the set interval, timer contacts switch to shut off the cooking operation and sound

a signal buzzer. The buzzer is silenced by returning the timer dial to the OFF position. In the
‘HOLD’ mode, the cooker will maintain a safe food holding temperature at or above 150°F.
Steam and liquids from each cooking cavity pass through a removable drain screen in the
cavity and into the tempering tank. When the appliance is shut off, the steam generators will
also drain into the tempering tank. The tempering tank condenses any residual steam and
tempers the waste water to 140°F or less.

3.0 INSTALLATION

SETTING IN PLACE

The location of installation must be under an exhaust hood, which will remove water vapour
emitted when the cooker door is opened, and exhaust combustion fumes. Level the unit in final
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 pages 4 and 5 for location of mechanical connections.

3.1 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, CSA
B149.1 as applicable.

1. The appliance and its individual shut off valve must be disconnected from the gas supply

piping system during any pressure testing of that system at pressures in excess of ½ psi
(3.5 kPa).

2. The appliance must be isolated from the gas 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 (3.5 kPa).

3.0 INSTALLATION (Continued)

3.2 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
floor. 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 filter. A strong exhaust fan tends to create a vacuum in the
room and may interfere with burner performance or may extinguish pilot flames. 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.

3.3 WALL EXHAUST FAN

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

3.4 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. Minimum clearance from combustible and noncombustible construction, 3"
on left side, 8" on right side and 6" from back.

WARNING: These procedures must be followed by qualified
personnel or warranty will be voided. An open gap floor drain is
required immediately below the appliance drain. See page 12.

To Install:

1. Uncrate carefully. Report any freight damage to the freight company immediately.

2. Set the unit in place. Be certain to maintain the minimum clearances from combustibles

and non-combustibles.

3. For an appliance supplied with legs, level the appliance using a spirit level. Rear flanged

adjustable feet are provided for permanent anchoring to the floor. With the unit in location,
mark hole locations on the floor through the anchoring holes. Remove the steamer and drill
holes at marked locations on the floor. Insert proper anchoring devices.

4. Set steamer back in proper position.

PART NUMBER 10205R3 8 2010-06-30

INSTALLATION, OPERATION AND PARTS MANUAL, MODELS ETP-5G & ETP-10G

3.0 INSTALLATION (Continued)

5. Install bolts through anchoring holes and into anchors to secure the steamer to the floor.

Seal bolts and flanged feet with Silastic™ or equivalent silicone sealant.

6. After the drain is connected, check for level by pouring water onto the floor of the

compartment. All water should drain through the opening at the back of the compartment
cavity.

WARNING: For an appliance equipped with casters, the installation
shall be made with a connector that complies with the Standard for
Connectors for Moveable Gas Appliances, ANSI Z21.69/CSA 6.16
and a quick-disconnect device that complies with the Standard for
Quick-Disconnect Devices for use with Gas Fuel, ANSI Z21.41/CSA

6.9; adequate means must be provided to limit the movement of the
appliance without depending on the connector and the quick­disconnect device or its associated piping to limit the appliance
movement: the location where restraining means may be attached
is directly above the gas supply inlet pipe on the rear of the
appliance.

The water inlet connections must also be installed with a flexible
water supply tube, a quick disconnect and strain relief.

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.

2. A ¾” NPT line is provided at rear for the connection. 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.

3.0 INSTALLATION (Continued)
WATER CONDITIONING: 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 extension 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 treat equipment for scale reduction.
This equipment is furnished with an Aqua-Pure® Commercial Series water filtration system. An
initial flushing procedure for the filter system must be performed before using this equipment.

FILTER SYSTEM INSTALLATION SET-UP

1. Remove sanitary cap from cartridge. Install cartridge with a quarter turn to the right until
cartridge comes to a complete stop. (A “click” is heard). (Figure 1)

2. It is recommended that cartridges be replaced regularly, at no more than six-month
intervals, to be assured of optimum performance. (Figure 2)

To replace cartridge:
a. Shut off inlet water.

b. Open a downstream valve to relieve pressure.
c. Unscrew the cartridge in the direction shown in the illustration and discard.
d. Lubricate o-ring of new cartridge with water. DO NOT use petroleum jelly.
