installed position as possible. Remove all shipping wire and wood blocking.
Before installing, check the type of gas supply (natural or propane) to make sure
they agree with the specifications on the rating plate located on the inside of the
lower kick panel. If the supply and equipment requirements do not agree, do not
proceed with the installation. Contact your dealer or SERV-WARE Company
immediately.
LOCATION
The appliance must be installed under a ventilation hood.
The equipment area must be kept free and clear of combustible substances.
7
The range, when installed, must have a minimum clearance from combustible
construction of 12" (304 mm) at the sides and 10" (253 mm) at the rear. Clearance from
non-combustible construction is 0" at the sides and 6" (152 mm) at the rear.
The installation location must allow adequate clearances for servicing and proper
operation. A minimum front clearance of 40" (1016 mm) is required.
The range must be installed so that the flow of combustion and ventilation air will not
be obstructed. Adequate clearance for air openings into the combustion chamber
must be provided. Make sure there is an adequate supply of air in the room to allow
for combustion of the gas at the burners.
INSTALLATION CODES AND STANDARDS
Ranges must be installed in accordance with:
In the United States of America:
1. State and local codes.
2. National Fuel Gas Code, ANSI/Z223.1 (latest edition). Copies may be obtained
from The American Gas Association, Inc., 1515 Wilson Blvd., Arlington, VA22209.

The above are available from the Canadian Standard Association, 5060 Spectrum Way, Suite
100, Mississauga, Ontario, Canada L4W 5N6.
ASSEMBLY: Ranges Mounted on Casters
Ranges mounted on casters must use a flexible connector (not supplied by SERV-WARE)
that complies with the Standard for Connectors for Movable 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. In
addition, adequate means must be provided to limit movement of the appliance without
depending on the connector and the quick-disconnect device or its associated piping to
8
limit appliance movement. Attach the restraining device at the rear of the range as shown
in Fig. 1.
Remove two screws from the rear of the range and install the tie-down strap shipped with
the casters using these screws (Fig. 1).
Attach the gas line strain relief to the tie-down
strap at the rear of the range (Fig. 1).
If disconnection of the restraint is necessary, turn off the gas supply before disconnection.
Reconnect this restraint prior to turning the gas supply on and returning the range to its
installation position.
Separate instructions for installing casters to the range are included with the casters.
Note: If the range is installed on casters and is moved for any reason, it is recommended
that the range be leveled front to back and side to side.

Fig. 12
11
LEVELING
Check the leveling of the range. Place a level inside the oven cavity across the
oven rack(s). Level front-to-back and side-to-side.
To adjust the leveling, tilt the range to one side and, using channel locks, unscrew
the adjustable leg insert as required. Repeat this procedure as necessary for each
leg.
Optional casters for this range are of the non-adjustable type. Therefore, the floor
must be level. If floor surface is not level, the range will experience cooking
problems.
GAS CONNECTIONS
CAUTION: All gas supply connections and any pipe joint compound used must be
resistant to the action of propane gases.
Each range is factory-equipped for the type gas specified on the rating plate. The
installation gas connection is a
3
/4" (19 mm) 14 FPT ANSI schedule #40 standard pipe.
Connect gas supply. Make sure the pipes are clean and free of obstructions. Codes
require that a gas shutoff valve be installed in the gas line ahead of the range. Standard
ranges are equipped with fixed burner orifices which coincide with installation elevation.
Install the gas pressure regulator.
Before installing, ensure that regulator supplied agrees with rating plate gas supply.
The gas pressure regulator is NOT factory installed. The regulator for this gas type
is sealed within a plastic bag attached to the oven rack inside the oven cavity. This
regulator must be field installed by a qualified installer.
Natural gas regulators are preset for 5" W.C. (Water Column) (.99 kPa);
propane gas regulators for 10.0" W.C. (2.5 kPa)
1. Locate
3
/4" (19 mm) gas connection pipe extending from rear of range.
2. Cover pipe threads with leak sealant.
3. Screw regulator hand-tight onto pipe with regulator arrow pointing towards range
body back (Fig. 13).
4. Using pipe wrench, tighten regulator securely in an upright position (Fig. 13).
12
Fig. 13
The arrow on the regulator shows the direction of the gas flow. The pressure
regulator must be mounted horizontally to ensure proper preset outlet pressure. If
the regulator is installed in any other position, the outlet pressure must be reset for
proper operation.
A leak limiter is supplied with every regulator to allow excess gas pressure to
escape. Do not obstruct leak limiter on gas pressure regulator, as obstruction may
cause regulator to malfunction.
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS
SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT
USE AN OPEN FLAME.
After piping has been checked for leaks, all piping receiving gas should be fully purged to
remove air.
Before operation, verify thermocouple is securely seated in the safety valve. The
thermocouple should be tightened a
1
/4 turn past finger tight. DO NOT OVERTIGHTEN.
Over-tightening may damage the thermocouple or safety magnet.
TESTING THE GAS SUPPLY SYSTEM
When gas supply pressure exceeds
1
/2 psig (3.45 kPa), the range and its individual
shutoff valve must be disconnected from the gas supply piping system.
When gas supply pressure is 1/
2 psig(3.45kPa) or less, the range should be isolated
from the gas supply system by closing its individual manual shutoff valve until the
range is ready for start-up.
FLUE CONNECTIONS DO NOT obstruct the flow of flue gases from the flue located on
13
the rear of the range. It is recommended that the flue gases be ventilated to the outside of
the building through a ventilation system installed by qualified personnel.
From the termination of the flue to the filters of the hood venting system, a minimum
clearance of 18" (457 mm) must be maintained.
Information on the construction and installation of ventilating hoods may be obtained from
the standard for the "Removal of Vapors from Commercial Cooking Equipment”, NFPA
No. 96 (latest edition), available from The National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269.
OPERATION
WARNING: THE RANGE AND ITS PARTS ARE HOT. BE VERY CAREFUL WHEN
OPERATING, CLEANING OR SERVICING THE RANGE.
CONTROLS
THERMOSTAT DIAL

BEFORE FIRST USE
Griddle Seasoning (
optional models
)
CAUTION: This griddle plate is steel, but the surface is relatively soft and can be scored
or dented by the careless use of a spatula or scraper. Be careful not to dent, scratch, or
gouge the plate surface. Do not try to knock off loose food that may be on the spatula by
tapping the corner edge of the spatula on the griddle surface.
A new griddle surface must be seasoned to do a good cooking job. The metal surface of
the griddle is porous. Food tends to get trapped in these pores and stick; therefore, it is
important to “season” or “fill up” these pores with cooking oil before cooking. Seasoning
gives the surface a slick, hard finish from which the food will release easily.
To season, heat griddle top section at a low burner setting. Pour one ounce of cooking oil
per square foot of surface over the griddle top section. With an insulated cloth, spread the
oil over the entire griddle surface to create a thin film. Wipe off any excess oil with an
14
insulated cloth.
Repeat this procedure 2 to 3 times until the griddle has a slick surface.
