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
Allows operator to regulate oven temperature from low to 500° F (260° C)
(OPTIONAL) GRIDDLE BURNER KNOB
Regulates gas flow to the griddle. To increase heat, turn knob counterclockwise, to
decrease heat, turn knob clockwise.
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.
