Installation
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.
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.
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
Chloride less than 30 parts per million
pH Factor greater than 7.5
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.
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
production. Before installing the steamer, please read
those instructions carefully to maintain your safety and
warranty

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 11/2-inch 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 coldwater 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.

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 pressure-regulating
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.

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
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 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 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

Operation of the Cleveland Range Convection Steamer is
very easy. Each operator should read and understand the
following procedures to effectively start, operate, and shut
down the steamer each day. The owner(s) and operator(s)
of this equipment should be aware that live steam could
cause serious injuries, pay particular attention to the
WARNINGS in this text. These instructions are to be
retained by the owner(s)) and operator(s) for future
reference.
CONTROLS AND CONTROL PANELS
There are two steam generator control arrangements and
two steamer compartment control panels available for
Cleveland Range Convection Steamers. The steam
generator controls are illustrated in Figure 2. The steamer
compartment control panels are illustrated in Figures 3
and 4. Compare these figures with the equipment
supplied, and identify which control panel combinations
applies.
Steam Generator Controls
The steam generator controls are located on the front face
of the steamer base unit. The switches are to the left of
the pressure gage, as illustrated in Figure 2 Most
Cleveland Range Convection Steamers have a steam
generator built into the base unit which supplies steam to
the cooking compartments. However, an external steam
supply may also be used. Units with a built-in boiler have
both the POWER rocker switch and the STEAM
momentary switch next to the pressure gage. Units with no
internal generator have the POWER rocker switch only.
They do not have the STEAM momentary switch.
