Equipment Description

Your 3-pan, 5-pan or 10-pan boilerless steamer is designed to give years of service. It has a stainless steel cavity (cooking chamber) which is served by an gas heated atmospheric steam generating reservoir. A powerful blower circulates the steam in the cavity to increase heating efﬁciency.

Each cavity holds up to three, ﬁve or ten steam table pans (12” x 20” x 21/2” deep) as shown below.

An 18-guage stainless steel case encloses the cavity, the steam generating reservoir and the control compartment that houses electrical components. Door hinges are ﬁeld-reversible (the door may be set to open from the left or right). Operating controls are on the front panel.

The boilerless steamers are equipped with fully electronic controls. These units are readily identiﬁed by their unique control panels. Steamer function is controlled by touch pad controls and a rotary timer-dial. The drain system on all models includes a spray condenser, which cools drain water.

Inspection & Unpacking

CAUTION

SHIPPING STRAPS ARE UNDER TENSION

AND CAN SNAP BACK WHEN CUT.

Your boilerless steamer will be delivered completely assembled in a heavy shipping carton strapped to a skid. On receipt, inspect carton carefully for exterior damage.

Carefully cut the straps and detach the sides of the carton from the skid. Pull the carton up off the unit. Be careful to avoid personal injury or equipment damage from staples which might be left in the carton walls. Write down the model number, serial number and installation date. Keep this information for reference. Space for these entries is provided at the top of the Service Log in the back of this manual.

Installation

WARNING

THE UNIT MUST BE INSTALLED BY

PERSONNEL WHO ARE QUALIFIED TO

WORK WITH ELECTRICITY AND PLUMBING.

IMPROPER INSTALLATION CAN CAUSE

INJURY TO PERSONNEL AND/OR DAMAGE TO

THE EQUIPMENT. THE UNIT MUST BE

INSTALLED IN ACCORDANCE WITH

APPLICABLE CODES.

CAUTION

DO NOT INSTALL THE UNIT WITH THE REAR

VENTS BLOCKED OR WITHIN 2 INCHES OF A HEAT SOURCE SUCH AS A BRAISING PAN, DEEP FAT FRYER, CHARBROILER OR

KETTLE. TO AVOID DRAINAGE PROBLEMS,

LEVEL THE UNIT FRONT TO BACK, AND

PITCH SLIGHTLY TO THE FRONT.

WARNING

THE AREA DIRECTLY AROUND THE

APPLIANCE MUST BE CLEARED OF ALL

COMBUSTIBLE MATERIAL. FAILURE TO

FOLLOW THESE INSTRUCTIONS CAN CAUSE

BODILY INJURY AND/OR PROPERTY DAMAGE.

IN CANADA, THE INSTALLATION MUST

CONFORM TO THE CANADIAN GAS CODE,

CAN 1-B149, INSTALLATION CODES FOR GAS

BURNING APPLIANCES AND EQUIPMENT

AND/OR LOCAL CODES.

Minimum Clearances: Boilerless steamer requires the following minimum clearances

to any surface, combustible or noncombustible.

Right Side 2 inches Left Side 2 inches Rear 6 inches

Steam Free Zone: The boilerless steamer can be damaged by steam from external sources. Do not install the steamer over a steam venting drain. Ensure that steam is not present in an area bounded by the footprint of the steamer and a circle 18 inches in radius about the right rear corner of the steamer (see ﬁgure at left).

Install and operate the gas appliance in a well ventilated area. Adequate air must be supplied to replenish the air used for combustion. Installation must conform with local codes and/or with the National Fuel Gas Code, ANSI Z223.1/NFPA-54 (latest edition) or the National Gas and Propane Code CSA B149.1 as applicable.

Any item which might obstruct or restrict the ﬂow of air for combustion and ventilation must be removed. Do not obstruct the ﬂue cover or rear vents after installation.

The steamer must be disconnected from the gas supply system during any pressure testing of that system which has test pressures in excess of 1/2 PSI (3.45 kPa).

1. Electrical Supply Connection Provide 115 VAC, 60 HZ, 1 PH, 15 AMP service. Bring wire in through hole in the

lower left back panel. Each cavity requires a separate cord for connections. Local codes and/or the National Electrical Code should be observed in accordance with ANSI/NFPA 70. AN ELECTRICAL GROUND IS REQUIRED. The wiring diagram is located in the service compartment and in this manual. Maximum load is 21/2 AMPs. In Canada, provide electrical service in accordance with the Canadian Electrical Code, CSA C22.2 Part 1 and/or local codes.

WARNING

DO NOT CONNECT THE DRAIN DIRECTLY

TO A BUILDING DRAIN. BLOCKING THE

DRAIN IS HAZARDOUS.

CAUTION

DO NOT USE PLASTIC PIPE. DRAIN MUST BE

RATED FOR BOILING WATER.

IMPORTANT

DO NOT ALLOW WATER TRAPS IN THE LINE.

A TRAP CAN CAUSE PRESSURE BUILD-UP IN

THE CAVITY, WHICH MAY CAUSE THE DOOR

For a Unit on casters: a. The installation shall be made with a connector that complies with the

standard for connectors for movable gas appliances; ANSI Z21.69.CSA

6.16, and a quickdisconnect device that complies with the standard for quick-disconnect devices for use with gas fuel, ANSI Z21.41.CSA 6.9.

b. Adequate means must be provided to limit the movement of the appliance

without depending on the connector and the quick disconnect device or its associated piping to limit the appliance movement.

c. The location where the restraining device may be attached to the appliance

shall be in accordance with speciﬁcations for the device.

3. Water Connection(s) Install a check valve to prevent back ﬂow in the incoming cold water line, as

required by local plumbing codes. Water pressure in the line should be between 30 and 60 PSI. If pressure is above 60 PSI, a pressure regulator will be needed. These pressures must provide the 1.5 gallons per minute required for proper steamer function.

A 3/4 inch female NH connector (garden hose type) is used to attach the water

supply to the inlet valve. Minimum inside diameter of the water feed line is 1/2 inch. Use a washer in the hose connection. Do not allow the connection to leak, no matter how slowly. Do not over-tighten hose connections.

This equipment is to be installed to comply with the basic plumbing code of the

Building Ofﬁcials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).

NOTE: Local code may also require check valves in the water supply line.

4. Drain Connection Level the steamer front to back, and pitch it slightly to the rear (maximum 1/4

inch) by adjusting the optional legs or the bullet feet on the optional stand.

There must be a free air gap between the end of the hose and the building drain.

The free air gap should be as close as possible to the unit drain. There must also be no other elbows or restrictions between the unit drain and the free air gap.

Install the drain line with a constant downward pitch.

Proper Drain Line Connection –– Drain Line must have a constant downward

pitch of at least 1/4” per foot. Observe local code regarding air gap spacing and drain connections.
