Installation, Operation and Care of
MG SERIES GAS RESTAURANT MODULAR RANGE
KEEP THIS MANUAL FOR FUTURE REFERENCE
Vulcan ranges are produced with quality workmanship and material. Proper installation, usage and
maintenance of your range will result in many years of satisfactory performance.
The manufacturer suggests that you thoroughly read this entire manual and carefully follow all of the
instructions provided.
INSTALLATION
UNCRATING
This range was inspected before leaving the factory. The transportation company assumes full
responsibility for safe delivery upon acceptance of the shipment. Immediately after unpacking, check
for possible shipping damage. If the range is found to be damaged, save the packaging material and
contact the carrier within 15 days of delivery.
Carefully uncrate range and place in a work-accessible area as near to its final installed position as
possible. Remove all shipping wire and wood blocking.
Before installing, verify that the type of gas supply (natural or propane) agrees with the specifications
on the rating plate located under the left-hand cooking top, mounted to the side wall of the range.
If the supply and equipment requirements do not agree, do not proceed with the installation. Contact
your dealer or Vulcan-Hart Company immediately.
LOCATION
CAUTION: The equipment area must be kept free and clear of combustible substances.
The 28,000 BTU burner input range must have a minimum clearance from combustible construction
of 10" (25 cm) at the sides and 6" (15 cm) at the rear.
The installation location must allow adequate clearances for servicing and proper operation.
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.

LEVELING
Check the leveling of the range. Place a carpenter’s level across the range top plates. 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.
GAS CONNECTIONS
CAUTION: All gas supply connections and any pipe joint compound used must be resistant to
the action of propane gases.
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
and packaged with the range. This regulator must be field
installed by a qualified installer.
Natural gas regulators are preset for 5.0" W.C. (Water
Column); propane gas regulators for 10.0" W.C.

1. Locate
/4" (1.9 cm) 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. 6).
4. Using pipe wrench, tighten regulator securely in
an upright position (Fig. 6).
Fig. 6
The arrow on the regulator shows the direction of the gas flow (Fig. 6). 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, because 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.
– 7 –
TESTING THE GAS SUPPLY SYSTEM
1
When gas supply pressure exceeds
/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 exceeds 1/2 psig (3.45 kPa) 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 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"
(45 cm) must be maintained.
Information on the construction and installation of ventilating hoods may be obtained from the
standard, “Vapor Removal from Cooking Equipment,” NFPA No. 96 (latest edition), available from The
National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
LIGHTING AND SHUTTING DOWN PILOTS
All adjustment procedures associated with initial start-up should be performed by an authorized
Vulcan-Hart installation or service person.
Open Top Burners
1. Turn main gas supply ON.
2. Turn all top burner valve knobs ON to purge gas
line of air.
3. Turn top burner valve knobs OFF.
4. Wait 30 seconds.
5. Using a taper, light the open top pilot (Fig. 7).
6. If pilot fails to light, wait 5 minutes and repeat Steps
1 thru 5.
7. Turn one open top burner valve ON to ensure that
all gas lines are completely purged of air. Turn
burner OFF when gas begins to flow.
Fig. 7
Nightly Shutdown: Turn burner valve OFF; pilot will remain lit.
Complete Shutdown
1. Turn burner valve OFF; pilot will remain lit.
2. Turn main gas supply OFF.

OPERATION
WARNING: THE RANGE AND ITS PARTS ARE HOT. BE VERY CAREFUL WHEN OPERATING,
CLEANING OR SERVICING THE RANGE.
CONTROLS
OPEN TOP BURNER KNOB — Regulates gas flow to top burners. To increase heat, turn knob
counterclockwise; to decrease, turn knob clockwise.
PREHEATING
Open Top Burners
Open top burners ignite quickly and do not require any preheating time. When food comes to a rolling
boil, cut back to slower boil to conserve energy, yet continue boiling. Turn burners ON only when in use.
CLEANING
®
Do not use Dawn
Do not use scouring powder; it is extremely difficult to remove completely and can build up
accumulations that will damage the range.
Vulcan painted surfaces may be cleaned using a soft cloth and mild detergent solution.
dish detergent to clean the exterior or interior components of the range.
Daily:
While still warm, wipe top with a soft cloth or other grease absorbing material to remove spillovers,
grease, etc., before they burn in. A crust on top of the hot top range looks unsightly and slows down
cooking speed because it reduces the flow of heat to the utensil.
Empty the grease pan daily or as often as necessary. CAUTION: Remove the grease pan slowly and
be careful of liquid wave action. It is recommended that the grease pan be emptied whenever it
is 3/4 filled. The drip shield, grids and grease pan should be washed with a mild grease-dissolving
solution.
Clean cast iron open top grates with a mild soap and water solution. Rinse thoroughly and dry with a
clean, water-absorbent towel. Immediately after drying (with grates still removed from the range top),
season grates lightly with liquid vegetable or Pam
®
spray-type cooking oil.
After seasoning, replace grates onto the range. Turn all open top sections ON LOW and allow them
to burn for at least 15 minutes before using pots or pans on the range top.
Season the open top grates after each cleaning. Failure to season grates will cause grates to
rust.
Thoroughly clean backsplash, sides and front. Remove grease drip tray and pan, empty and wash out
in the same manner as any ordinary cooking utensil.
– 9 –
Weekly:
Boil burners in a solution of washing soda. Rinse and dry parts thoroughly. Flash rusting may occur.
This is a normal condition and will not affect performance or the product.
When reinstalling the burner back onto the range, be sure the burner heads are properly connected.
Do not light the pilot or turn burner valve ON with the burner head removed.
MAINTENANCE
WARNING: THE RANGE AND ITS PARTS ARE HOT. BE VERY CAREFUL WHEN OPERATING,
CLEANING OR SERVICING THE RANGE.
