The following general safety notices supplement the specific
warnings and cautions contained in this technical manual. They are
recommended precautions that must be understood and adhered to
during the installation, operation, and maintenance of these
electrically operated appliances.

CAUTION

Do not install in such a manner that the service person cannot
remove the control box cover.

Supply wires must be suitable for temperature of at least 90°C.
Additionally, all wiring must conform to the requirements of local
and national electric codes. Conduit and fittings should be

cooking surface with reinforcement. Gas burners turn off
automatically when the cooking pan is raised to a tilted position.
The skillet is provided with a heavy -duty gas shock assisted cover
with condensate vent. The cooking pan and cover are mounted to a
l'/2" (38 mm) square stainless steel tube frame, permitting access to
floor for easy cleaning. The closed-base model incorporates easily
removable stainless steel panels on the front, and left sides. The
cooking pan tilts to a full 93°. This is accomplished by a gear
mechanism operated manually with a collapsible hand crank. Power
tilting is also available. Both tilting methods allow complete emp
tying of contents under positive control.

The Market Forge Gas UniVerse Tilting Skillets™ are available in
30-gallon (87-liter) and 40-gallon (114-liter) pan bodies with
108,750 BTU and 145,000 BTU inputs, respectively. Both models
are available in open-leg and closed-base frame assemblies with
manual or power tilt capabilities.

Benefits: Our UniVerse Skillets, unlike those of other brais ing pan
manufacturers that use clad plates, incorporate a uni-pan design.
This design reduces the potential for leaks and eliminates the
possibility of pitting and surface rust. The new center-of-gravity
tilting allows for safe use of caster mounting. Our new power tilt
operates smoothly, with manual override that works easily when
needed, without the use of electric drills required by other
manufacturers.

DESCRIPTION

TECHNICAL SPECIFICATIONS

Cooking Pan: The unitized cooking pan has no bottom weld and is
reinforced to resist cracking as expansion and contract tion occur.
The textured cooking surface is machine-applied' for a long­wearing, good appearance. The cooking pan in corporates an easy ­pour lip and 5-gallon increment markings
Gas flames are applied to finned aluminum extrusions bolted to the
underside of the cooking pan for better heat transfer, An interlock
switch is provided to cut gas to the burners when the pan is tilted
more than 10° from the normal horizontal;
cooking position. The counterbalanced cover is pivoted from the
frame using gas shocks to assist lifting and ease of use.. lift handle
is provided along the front edge of the cover.. manually opened
condensate vent is positioned in the cent* of the cover.

Controls: The UniVerse Tilting Skillet™ comes standard with a
solid-state temperature controller with a positive OFF posi tion and
100°-450° Fahrenheit scale, a pilot light to indicate when the gas
burners are ON, and a 1-hour mechanical time Optional power
tilting mechanism also utilizes an UP/DOWN rocker switch.
Manual tilting mechanism uses a collapsible hand crank located
below the control panel. A high -limit tem perature control is also
provided. The control housing sh;
be water-resistant/splash-proof.

Operation: The UniVerse Tilting Skillet™ Models 40-STGL and
40-STGL will be rated at 145,000 BTU at 4- W.C. natu ral gas and
10" W.C. propane gas. Models 30-STGM a 30-STGL will be rated
at 108,750 BTU at 4" W.C. natu gas and 10" W.C. propane gas.

GENERAL INSTALLATION

1. Remove carton from skid, being careful not to dent or
scratch finished surfaces of unit.

2. Inspect unit carefully for shipping damage. File claim
with carrier immediately if damage is found.

3. Remove screws holding unit to skid.

4. Transfer unit to desired position and make level and
steady by adjusting feet to compensate for floor irregu­larities. Bolt the flange feet to floor.

5. Raise skillet cover to full OPEN position. Raise skillet by
turning handcrank clockwise. Check to make sure burn­ers and carry-over tube are in position and securely
seated.

6. Lower skillet by turning handcrank counterclockwise
until fully seated on frame. Skillet is equipped with in­terlock switch, which does not permit burners to ignite
until skillet is lowered to less than 10° off normal hori­zontal cooking position.

NOTE: "LX" models may be raised or lowered using tilt

switch after connecting to electrical supply.

7. Gas service connections:

a. This unit is factory -adjusted for gas consumption of

108,750 Btu/Hr. (on 30-gallon unit) or 145,000 Btu/
Hr. (on 40-gallon unit) at the pressure indicated.
Please read the rating plate on top of control box. If
this plate is marked for a different gas than that sup­plied, notify your dealer immediately.
Do not connect gas lines. Only a qualified in­staller or service man should make the installation.

b. Use new 3/4 I.P.S. iron or steel pipe complying with

ANSI Standard for Wrought -Steel and Wrought-Iron
Pipe B36—latest edition, properly threaded, reamed,

and free from chips, oil, and dirt.
If pipe dope is used, apply a moderate amount,
leaving two end threads bare. Connect the gas line

into bottom (inlet) side of shutoff valve with a union
and make accessible to the operator.

c. Natural gas units are equipped with a pressure regu-

lator factory -adjusted to give 4" (102 mm) water col­umn manifold pressure. The supply pressure must
be at least 5" (127 mm) water column pressure.

d. Propane gas units are equipped with a pressure

regulator factory -adjusted to give 10" (254mm) water
column manifold pressure. The supply pressure must
be at least 11" (279 mm) water column pressure.

Maximum supply pressure must not exceed 1/2 psig
(3.45 k/PA) for both natural and propane gas.

well as those leading to the main gas control valve
and pilot burner, using a soap solution. DO NOT
USE FLAME.

8. Electrical service connection:
Connect skillet controls to 110/120 volt AC, 60 Hz,

Operation of UniVerse Tilting Skillet™ (with Pilot)

MODELS: 30-STGL, 40-STGL, 30-STGM, 40-STGM, Gas, Standing Pilot

30-STGL-LX, 40-STGL-LX, 30-STGM -LX, 40-STGM-LX, Gas, Standing Pilot

with Power Tilt

1. Check to see that the correct gas connection has been
made to the unit, the electric 110/120-volt connection
has been made, and the pilot has been lighted.
(Instructions for lighting pilot are on a plate on control
box.) REF. SECTION 2.

2. Be sure skillet has been or is cleaned before using.

3. Turn main gas cock to ON.

4. Be certain skillet is lowered to the normal horizontal
cooking position (or as much as 10° above) so burners
will light.

5. Set the thermostat to the desired temperature. See
Section 4—Test Kitchen Bulletin for thermostat
settings.

7. Cover should be up for most types of cooking, except
simmering or boiling. The cover has a lip at the rear that will
direct condensate into the skillet rather than onto the cabinet
base.

8. When food is cooked, it should be immediately removed
from skillet to prevent overcooking.

9. To lower skillet, merely turn tilt skillet handcrank coun­terclockwise. To raise skillet, turn handcrank clockwise.

NOTE: "LX" models are raised and lowered using switch on

front of control box.

10. For cleaning instructions, see Section 6—Troubleshoot­ing and Maintenance.

6. Preheat to desired setting before grilling, pan frying, or
any other type of cooking except boiling.

NOTE: For best results, allow unit to cycle ON/OFF once.

Caution: Be Sure to Read

• Disconnect the power supply to skillet before clean­ing or servicing. (NOTE: "LX" models should have
the skillet raised to washing position before discon­necting power supply.)

• Keep this appliance area free and clear of combus ­tibles.

• Do not obstruct the flow of combustion and ventila­tion air.

• If skillet pan is difficult to raise, the lift gears may
need to be lubricated. The gears are located on the
right side under the control box. Apply a liberal
amount of grease along the helical thread of the
worm where it engages the worm gear. Use multi ­purpose, NLGI #2 lithium-based, water-resistant
grease.

• Keep this manual for future reference.

• Consult the factory, the factory representative, or a

local service company to perform maintenance and
repairs.

• In the event of a power failure, do not operate appli­ance.

• Periodically examine the flue outlet located behind
the skillet cover for any obstructions.

• Appliances with casters are always to be restrained
from movement. If removal of the restraint is neces­sary, always reconnect the restraint when the appli­ance is returned to its originally installed position.
