CORRECT INSTALLATION
You have purchased the finest Steam Cooking Equipment
made. The following information we know will increase the
productivity and life span of the equipment.
Every product needs proper installation and with a
steamer it is critical. The following is some important
information you should check on before and during
installation of the equipment.
Water
The quality of water you put into the steam generator is
important. Poor quality water will create generator problems.
Water is no longer just plain and simple. Water has many
natural ingredients in it. These are called Total Dissolved
Solids, or TDS. This includes calcium, iron, and other
minerals in the water that collect in the steam generator
Because of the droughts in many areas, water and TDS's
are being pumped up from the bottom of the water
systems. If these TDS are not pre-filtered out or cleaned
out with a regular preventive maintenance program, your
steam generator could deteriorate and develop holes.
CHLORIDE is another chemical in our water creating
many problems with all steam generators. When the generator creates steam from the water it also carries the
chloride gas with it. These chlorides begin to eat away the
inside of the generator and follow the steam into the
compartments causing a rusting action (oxidation) as it
goes along.
A CARBON OR CHARCOAL FILTER must be installed on
the incoming water line to the steamer if the chlorine is
over 30 parts per million. These filters will remove the
chloride.
The WATER QUALITY REQUIREMENTS for your
STEAMER are as follows:
Total Dissolved Solids less than 60 parts per million
Total Alkalinity less than 20 parts per million
Silica less than 13 parts per million
Chlorides less than 30 parts per million
pH Factor greater than 7.5
Figure 1. Drain Connections
If the drain line is not large enough, not open at the end,
or does not have a gravity flow; pressure and hot water
will back up into the compartments. If any of these conditions exist and hot water does back up into the compartment someone could be seriously burned and injured.
This can happen even with a correct installation if a drain
cleaner is not used on a regular basis.
An open and free flowing drain line IS REQUIRED for the
proper cooking performance of a CONVECTION
STEAMER. It helps create a swirling action around the
products being cooked. This movement of hot steam
around the product is your CONVECTION STEAM
COOKING.
DO NOT INSTALL UNIT OVER A FLOOR DRAIN. If it
becomes an absolute must, using an 18.' stainless steel
or aluminum pan turn it over and cut a notch in the side
wall to fit over the drain line. Place the pan directly over
the drain opening- DO NOT SEAL TO THE FLOOR. The
steam from the drain line will collect on the under side and
condense into the drain opening.
DO NOT INSTALL GAS UNITS ON
FLAMMABLEFLOORS OR NEAR WALLS. A flammable
floor or wall is any material such as wood, linoleum, or
vinyl that is easily ignitable and bums rapidly.
The intent of these instructions is to provide meaningful
information, which will help you obtain many years of
Drain Line Connection
A proper drain line connection is important. If the drain
line is clogged it can create a back up of pressure causing
extreme and costly repairs.
production. Before installing the steamer, please read
those instructions carefully to maintain your safety and
warranty.

INSTALLATION INSTRUCTIONS
1. These instructions must be retained by the owner/user
for future reference. Gas-fired boilers are only to be installed in noncombustible areas that have provisions for
adequate air supply. The term "boiler’
onymously with "steam generator".
2. Position: For proper operation and drainage, the equipment must be level. It should be placed next to an open
floor drain. DO NOT POSITION THE UNIT DIRECTLY
ABOVE WE FLOOR DRAIN. Observe all clearance requirements to provide air supply for proper operation,
as well as sufficient clearance for servicing. The
surrounding area must be free and clear of
combustibles. Dimensions and clearance specifications
are shown on the specification sheet.
3. Install in accordance with local codes and/or the National Electric Code ANSI/NFPA No.70-1987.
Installation in Canada must be in accordance with
Canadian Electrical Code CSA Standard C22.1. The

WARNING
INJURY TO PERSONNEL AND EQUIPMENT DAMAGE
May result from an improper drain connection. No
connection lines are to be under the unit
4. Drain Line. The drain line outlet discharges exhaust
steam and hot condensate. Connect 1-1/2-inch IPS
piping (or larger) to extend the drain line to a nearby
open floor drain. Up to two elbows and six feet of 1-1/2inch IFS (or larger) extension pipe should be connected
to the drain termination. No more than two pieces of
Cleveland Range Equipment should be connected to
one common drain line. The extension piping must have
a gravity flow and vent freely to the air. This drain outlet
must be free-vented to avoid the creation of
backpressure in the steamer cooking compartments. To
ensure a vented drain line, DO NOT UNDER ANY
CIRCUMSTANCES, CONNECT THE DRAIN OUTLET
DIRECTLY TO THE FLOOR DRAIN OR SEWER LINE.
Do not run the drain line discharge into PVC drain
piping or any other drain piping material not capable of
sustaining 180' F operation.
5. Water Supply. Connect COLD water plumbing to the
line strainer (Never conned hot water to the condensate
water fill line strainer) Constant flow pressure must be
maintained between 35 and 60 psi, and not experience
a pressure drop below 35 psi when other appliances
are used. If the water pressure exceeds 60 psi, a
pressure-reducing valve must be installed in the water
supply plumbing to reduce the water pressure to less
than 60 psi. Locations and pressure data are shown on
the specification sheet. 3/S-inch IPS plumbing is
sufficient for water supply lines up to 20 feet in length,
but water supply lines longer than 20 feet should be at
least 1/2-inch IPS. Flush water supply lines thoroughly
before connecting them to the unit. Use water, which is
low in total dissolved solids content and low in gas
content to prevent internal scaling, pitting and corrosion
of the steam generator, and carry-over of minerals into
the steam. Water, which is fit to drink, can still contain
highly detrimental impurities.
NOTE: If equipped with a kettle and kettle water fill
swing spout, 3/8-inch (10 mm) hot and/or
cold-water connection(s) will be required at
the swing spout valve.
6. Turn on the cold water supply to the unit Ensure that
the manual water valve, inside the base cabinet is
open.
7. Fuel Supply. Connect the primary fuel supply in accordance with the following instructions. Location and other
data are shown on the specification sheet.
For Gas-Fired Steam Generators: Post in a prominent
location, instructions to be followed in the event the user
smells gas. This information shall be obtained by the
consulting the local gas supplier.

Install a sediment trap (drip leg) in the gas supply line,
and then connect gas supply piping to the boiler gas valve
piping. GAS-FIRED EQUIPMENT IS DESIGNED FOR
INSTALLATION ONLY IN NONCOMBUSJJBLE
LOCATIONS. THIS INCLUDES THE FLOOR-INC THAT
WILL BE DIRECTLY UNDER THE EQUIPMENT Location,
plumbing size, and pressure data are shown on the
specification sheet. Boilers rated at less than 225,000 Btu
require 3/4-inch 'PS gas supply piping, and boilers rated
at 225,000 Btu or more require 1-inch II'S gas supply
piping. Natural gas pressure must be between 4" -14"
water column and LP gas supply pressure must be
between 12" - 14" water column. NEVER EXCEED 14"
WATER COLUMN (1/2 psi) GAS PRESSURE. If the gas
supply pressure exceeds 14" water column, a pressureregulating valve must be installed in the gas plumbing to
reduce the gas pressure to less than 14" water column.
Installation must be in accordance with local codes, or in
the absence of local codes, with the National Fuel Gas
Code, ANSI Z223.1-1984. Installation in Canada must be
in accordance with Installation codes for Gas Burning
Appliances and Equipment B149.1 and B149.2. Use a gas
pipe joint compound, which is resistant to LP gas. Turn
the gas valve control knob to ON (the word "on" the knob
will be opposite the index on the valve's body). Test all
pipe joints for leaks with soap and water solutions. Never
obstruct the flow of combustion and ventilation air
Observe all clearance requirements to provide adequate
air openings into the combustion chamber. The appliance
and it's individual shutoff valve must be disconnected from
the gas supply piping system during any pressure testing
of that system at test pressures in excess of 14" water
column (1/2 psi or 3.45 k}'a). The appliance must be
isolated from the gas supply piping system at test
pressures equal to or less than 14" water column (1/2 psi
or 3.45 kpa). A permanent 115-volt electrical connection is
required at the junction box. The junction box location is
shown on the specification sheet. The installer must
electrically ground the unit.
For Electric-Powered Steam Generators: Connect
electric power: location and data are shown on the
specification sheet. Provide connection as required by the
unit, either directly to the single contactor, or to the
terminal block (when equipped with multiple contactors).
Electric supply must match power requirements specified
on the data plate inside the base cabinet. The copper
wiring size must be adequate to carry the required current
at the rated voltage. A separate fused disconnect switch
must be supplied and installed. The installer must
electrically ground the unit
For Steam Coil Steam Generators: Connect steam
supply piping to the input side of the steam coil. Location
and pressure data are shown on the specification sheet.
Incoming steam pressure must be regulated between 35
and 45 psi. A 3 /4inch strainer, equipped with a 20 mesh
stainless steel screen, must be supplied and installed at
the incoming steam connection
point. Flush the steam
line thoroughly before connecting it to the boiler. To
ensure an adequate volume of steam, the branch steam
supply line must be 3/~inch 'PS minimum. Connect the
inverted bucket trap to the outlet end of the steam coil. Pill
the trap with water before installing it. A permanent 115volt electrical connection is required at the junction box.
The junction box location is shown on the specification
sheet. The installer must electrically ground the unit.
For Direct-Steam Connected Steamers and Kettles:
Connect steam supply piping to the input side of the line
strainer. Location and pressure data are shown on the
specification sheet. Flush the steam line thoroughly
before connecting it to the steamer. To ensure an
adequate volume of steam, the branch steam supply line
must be 3/4 inch 'PSI 'minimum. Direct-steam-connected
kettles require 1 /2-inch 'PS pipe if the kettle total capacity
is 20 gallons or less, and 3/4-inch 'PS pipe if the total
capacity exceeds 20 gallons.) A permanent 115-volt
electrical connection is required at the junction box. The
junction box location is shown on the specification sheet.
The installer must electrically ground the unit
INSTALLATION CHECKS
Proper operation of the Cleveland Convection Steamer is
dependent upon proper installation. After the steamer has
been installed, a few quick checks could save
unnecessary service calls.
1. The unit must be level.
2. The Convection Steamer requires a cold water
connection for proper efficient operation. DO NOT
USE HOT WATER. The cold water must be
connected to the line strainer, located at the front
lower right of the steamer base.
3. Check that the manual water supply valve is open.
4. Check all water supply lines and valves for leaks.
5. Check that the water supply pressure and water
quality meets the requirements of installation
paragraphs.
6. On electrical units, verify that the supply voltage
meets the voltage requirements on the rating plate
inside the base cabinet and the voltage shown on the
packing slip. Verify that the unit is protected with a
separate fused disconnect and is properly grounded
in accordance with the National Electric Code.
