INSTALLATION AND OPERATION MANUAL
FOR GR SERIES GAS FRYERS
KEEP THESE INSTRUCTIONS FOR FUTURE USE
GENERAL
Vulcan-Hart GR Series Gas Fryers are available in
5 sizes with an array of features and options for a
range of commercial fryer applications. While the
overall tank width on the GR35 and GR45 are the
same, the GR45 has a deeper tank area than GR35.
Thus the GR45 has larger tank capacity than GR35
but not as large as GR65. Likewise the GR65 and
GR85 are the same width, but the GR85 with a
deeper tank area has a larger tank capacity than the
GR65. Each gas burner tube has 30,000 BTU input
rating.

INSTALLATION
Before installing the fryer, verify that the type of gas
(natural or propane) agrees with the specifications on
the fryer data plate which is located on the inside of
the door panel. Also be sure the unit is built for the
installation elevation.
UNCRATING
This fryer was carefully inspected before leaving the
factory. The transportation company assumes full
responsibility for safe delivery upon acceptance of
the shipment. Immediately after unpacking the fryer,
check it for possible shipping damage. If the fryer is
found to be damaged, save the packaging material
and contact the carrier within 15 days of delivery.
Do not use the door or its handle to lift or move the
fryer.
LOCATION
The equipment area must be kept free and clear of
combustible substances.
Minimum clearance from combustible construction is
6" from the sides and 6" from the back of the fryer.
Minimum clearance from non-combustible
construction is 0" from the sides and 6" from the back
of the fryer. There must be at least 16" clearance
between the fryer and any open top flame units.
Adequate clearances for servicing and proper
operation must be allowed. The unit may be installed
on combustible floors.
Install the fryer in an area with sufficient air supply for
combustion of the gas at the fryer burners. Provide
adequate clearance for air openings into the
combustion chamber. Do not obstruct the flow of
combustion and ventilation air.
Do not permit fans to blow directly at the fryer. Avoid
open windows next to the unit sides or back. Avoid
wall-type fans which create air cross currents within
the room.
INSTALLATION CODES AND STANDARDS
Vulcan-Hart fryers should be installed in accordance
with state and local codes, or in the absence of
local codes, with the National Fuel Gas Code,
ANSI-Z223.1 (latest edition), available from
American Gas Association, Inc., 1515 Wilson
Boulevard, Arlington, VA 22209, and with ANSINFPA Standard #96,
Equipment,
(latest edition) available from the
Vapor Removal from Cooking
National Fire Protection Association, Batterymarch
Park, Quincy, MA 02269.
ASSEMBLY
The fryer must be restrained to prevent tipping when
installed in order to avoid the splashing of hot liquid.
The means of restraint may be the manner of
installation, such as connection to a battery of
appliances or installing the fryer in an alcove, or by
separate means, such as adequate ties.
Legs
Position fryer in an open space near the final
installation area. Tilt fryer on its side, being careful to
avoid scratching the finish. Thread legs into mounting
holes provided on bottom of fryer by screwing in a
clockwise rotation until tight.
Carefully raise fryer to its normal position and place
it in installing location.
Casters (Optional)
It is recommended that casters be installed on all
batteried appliances.
If the fryer is equipped with casters the gas connector
(available from Vulcan-Hart) must comply with the
Standard for Connectors of Movable Gas
Appliances, ANSI-Z21.69 (latest edition), and a
quick-disconnect device that complies with the
Standard for Quick-Disconnect Devices for Use With
Gas Fuel, ANSI-Z21.41 (latest edition).
Provide a gas line strain relief (Fig. 1) to limit
movement of the fryer without depending on the
connector and/or any quick-disconnect device or its
associated piping to limit the appliance movement.
If it is necessary to disconnect the restraint, turn off
the gas supply before disconnection. Reconnect the
restraint before turning the gas supply on and returning
the unit to its installation position.
Instructions for installing casters to the fryer are
included with the casters.

GAS CONNECTIONS
FLUE CONNECTIONS
CAUTION: All gas supply connections and any
pipe joint compound must be resistant to the
action of propane gases.
The gas inlet is located at the lower right rear. Codes
require that a gas shutoff valve be installed in the gas
line ahead of the fryer.
The gas supply line must be at least the equivalent of
1
⁄2" iron pipe. If using the optional quick-disconnect
flex hose,
1
⁄2" reducing fittings are used. Make sure the pipes
3
⁄4" iron pipe must be used unless 3⁄4" to
are clean and free of obstructions, dirt, and
piping compound. A battery requires one or two
connections of appropriate size and type for the
gas requirement.
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, fully purge
gas pipes to remove air.
GAS PRESSURES AND ORIFICES
The standard orifices are set at 4" W.C. (Water
Column) pressure for natural gas and 10" W.C.
(Water Column) pressure for propane gas. A
pressure regulator is supplied as part of the gas
control valve.
TESTING THE GAS SUPPLY PIPING SYSTEM
1
When test pressures exceed
⁄2 psig (3.45 kPa),
the fryer and its individual shutoff valve must be
disconnected from the gas supply piping system.
The fryer must be located under a hood which has
an adequate connection to an exhaust duct. The
hood must extend 6" beyond fryer sides.
Adequate ventilation must be provided and must
comply with NFPA Standard #96, (latest edition),
and with local codes.
Clearance above fryer should be adequate for
products of combustion to be removed efficiently.
An 18" minimum clearance should be maintained
between the flue vent and the filters of the hood
venting system.
Never make flue connections directly to the fryer.
Do not obstruct the flow of the flue gases from the
flue duct located at the rear of the appliance.
Adequate air should be provided in the kitchen to
replace air taken out by the ventilating system.
This will prevent fryer function from being affected
by a reduced atmospheric pressure.
ELECTRICAL CONNECTIONS
WARNING: ELECTRICAL AND GROUNDING
CONNECTIONS MUST COMPLY WITH THE
NATIONAL ELECTRICAL CODE, ANSI/NFPA 70
OR THE CANADIAN ELECTRICAL CODE, CSA
C22.2 AND/OR OTHER LOCAL CODES.
WARNING: APPLIANCES EQUIPPED WITH
ELECTRICAL SUPPLY CORD(S) ARE PROVIDED
WITH A THREE-PRONG GROUNDING PLUG
WHICH MUST BE CONNECTED TO A PROPERLY
GROUNDED RECEPTACLE. IF THE RECEPTACLE
IS NOT THE PROPER GROUNDING TYPE,
CONTACT AN ELECTRICIAN. DO NOT REMOVE
THE GROUNDING PRONG FROM THE PLUG.
1
When test pressures are
⁄2 psig (3.45 kPa) or
less, the fryer must be isolated from the gas
supply piping system by closing its individual
shutoff valve.
LEVELING THE FRYER
Once gas connections have been made, place a
spirit level on top of the fryer. Adjust the legs to
ensure that the fryer is level front-to-back and
side-to-side in the final installed position.
Some fryers (depending on options) are equipped
with a 120 Volt/60 Hz./1 Phase cord and plug
which requires only that it be plugged into a
properly grounded 120 volt receptacle.
Do not connect fryer to electrical supply until after
gas connections have been made.

FRYING (All Models)
Heat shortening to set temperature.
Pieces of product to be fried should be about the
same size to ensure the same doneness.
Batter-covered foods should be dropped carefully,
one by one, into shortening or basket. If you use
the basket, first dip basket into shortening to
reduce batter build-up on basket surfaces.
Corn-on-the-cob must be submerged to fry
uniformly. Place corn in bottom of basket. Stack
an empty basket on top of corn to keep it submerged.
When frying is completed, remove baskets or
product. Hang baskets on rear basket hangers.
Remove food and season it. Do not salt food over
the shortening because salt could cause a chemical
change in the oil.
DAILY (All Models)
Add approximately 15% new shortening daily. Keep
level of shortening at "fill level" line in fry tank. Add
fresh shortening as needed.
Drain or wipe dry raw or wet foods to minimize
splatter when lowering into the hot oil.
Do not overfill baskets.
Recommended maximum capacities are:

Carefully lower baskets into oil.
When frying doughnuts and fritters, turn product
only once during frying.
When cooking French fries or onion rings, shake
basket several times in a way that does not splatter
the shortening.
DAILY FILTERING
Fryers Without Filter Ready Options
Turn gas valve off when draining or filling.
Always filter the shortening while liquified. A cold
fryer will not drain properly because the shortening
under the cold zone tube area will remain hard,
even if the heat is on for a few minutes. If necessary,
the clean-out rod may be used to carefully stir up
hard fat to an area above the cold zone (see Fig. 4)
where it will melt. After the cold zone is liquified,
turn the fryer thermostat and gas valve off.
Shortening life will be extended by filtering at least
once a day or more often if conditions warrant. A
commercial power filter (available from other
manufacturers) may be used. Follow the
manufacturer's operating instructions for draining,
straining, and replacing shortening in the fry tank.
Another way to filter is to drain the shortening from
the drain pipe through a filter bag, or cover the
receiving container with cheesecloth or other
filtering material.
12
Filtering Procedure (Not Filter Ready)
1. Turn the fryer off.
Always be sure you have adequate container
capacity before opening drain; monitor draining
process.
2.Slowly remove the baskets, especially if
shortening is hot, to prevent splashing.
3.Open the fryer door and attach the drain pipe to
the drain valve.
4. Select a container of sufficient capacity and
place it below the drain pipe.
5. If you are using a filter bag, tie it securely to the
drain pipe. If other filter medium is used, place
it in the container.
6. Open the drain valve carefully so the oil stream
is directed through the filter.
7. With a small amount of warm shortening, flush
out scraps and sediment in the fry tank. Drain
the tank thoroughly and wipe clean.
8. Should it be necessary to clean the tank more
thoroughly, follow the procedure shown in
CLEANING — WEEKLY OR AS REQUIRED in
this manual.
9. Close the drain valve.
After oil has filtered into the mobile filter, it is
pumped back to the individual tank by (1) closing
the drain valve, and (2) opening the valve on the
return line (Fig. 7). Only one return valve should be
opened at any one time.
After oil is pumped back, close the return valve. Fill
tank to the "fill level" line on the back wall of the fry
tank.
Fig. 7
SHORTENING LIFE (All Models)
Shortening life may be extended by following these
guidelines:
10. Pour strained shortening back into the tank.
11. Add shortening to the "fill level" line.
Filter-Ready Fryers Only
Follow instructions in the MOBILE FILTER
OPERATING MANUAL shipped with the mobile
filter. If the manual is not found, contact your
dealer to obtain the manual before operating the
mobile filter.
Battery Interplumbing (Optional)
A battery of fryers equipped with optional
interplumbing connects the fry tanks to a common
drain. Each tank has an individual drain valve;
these should only be opened one at a time.
• Do not salt foods over the fryer.
• Use good quality shortening.
• Filter shortening daily at a minimum.
• Replace shortening if it becomes poorly
flavored.
• Keep equipment and surroundings clean.
• Set thermostats correctly.
• Remove excess moisture and particles from
food products before placing in fryer.
HIGH LIMIT DEVICE (All Models)
If the shortening becomes overheated, a high
temperature shutoff device will turn the gas valve
off and extinguish the pilot. DO NOT relight the
pilot until the shortening temperature is below
300°F. If this situation persists, contact your local
Vulcan-Hart authorized service office.
13
CLEANING (All Models)
WARNING: DISCONNECT ELECTRICAL POWER
SUPPLY BEFORE CLEANING.
2. Close the drain valve and fill the tank with a
non-corrosive, grease-dissolving commercial
cleaner, following the manufacturer's
instructions.
Daily
Clean the exterior of your fryer regularly with a
damp cloth and polish with a soft dry cloth. If
regular cleaning is neglected, grease will be burned
on and discolorations may form. These may be
removed by washing with any detergent or soap
and water. A self-soaping scouring pad may be
used for particularly stubborn discolorations.
Always rub with the "GRAIN" in a horizontal
direction.
Keeping the fryer exterior clean and free of
accumulated grease will prevent stubborn stains
from forming. Wash all exterior surfaces at least
once daily. Use a cloth with warm water and a mild
soap or detergent. Follow with a clear rinse, then
dry.
Fingerprints are sometimes a problem on highly
polished surfaces of stainless steel. They can be
minimized by applying a cleaner that will leave a
thin oily or waxy film.
3. Set the thermostat at a temperature
recommended by the manufacturer of the
commercial cleaner and boil the solution for 15
to 20 minutes. If cleaner is a water based
chemical, temperature may be 190 - 212°F.
Set the temperature as low as possible; monitor
boiling to prevent overflow.
4. Drain the cleaning solution from the tank.
5. Close the drain valve and refill the tank with
water. Add 1 cup of vinegar to neutralize
alkaline left by the cleaner. Bring the solution
to a boil and allow it to stand for a few minutes.
6. Drain the tank and rinse thoroughly with clear
hot water. All traces of cleaner must be
removed. Dry the tank thoroughly.
7. Close the drain valve.
8. Add shortening the the "fill level" line in the fry
tank.
Weekly or as Required
1. Once the shortening has been drained, flush
out scraps and sediment with a small amount of
warm shortening. Allow the tank to drain
thoroughly.
The fryer is now ready for use.
