GRM SERIES GAS FRYERS
ASSEMBLY
The fryer must be restrained to prevent tipping and the splashing of hot liquid. The means
of restraint may be the manner of installation, such as connection to a battery of
appliances, installing the fryer in an alcove, or by separate means such as adequate ties.
FLUE CONNECTION
Make the flue connection as follows:

Comply with Vapor Removal from Cooking Equipment, ANSI-NFPA Standard #96
(latest edition), available from the National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269.

Locate the fryer under a hood with adequate connection to an exhaustduct. The
hood must extend 6” (15 cm) beyond fryer on both sides.

Clearance above the fryer should be adequate for combustion byproducts to be
removed efficiently.

An 18” (46 cm) 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 gases from the appliance. Proper air balance should
be maintained in the room.

Ensure that your ventilation system does not cause a down draft at the fryer’s flue
opening. Down draft will not allow the fryer to exhaust properly and will cause
overheating which may cause permanent damage. Damage caused by down draft
will not be covered under equipment warranty. Never allow anything to obstruct the
flue or ventilation exiting from the fryer flue. Do not put anything on top of flue area.
GAS CONNECTION
All gas supply connections and any pipe joint compound must be
resistant to the action of propane gases.
The gas inlet is located on the lower rear of the fryer. 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 ½” (12.7 mm) iron pipe for single
units and 1-1/4” (31.75 mm) for batteries. If using the optional quick-disconnect flex hose,
¾” (19 mm) iron pipe for single units and 1-1/4” (31.75 cm) iron pipe for batteries.
Make sure the pipes are clean and free of obstructions, dirt, and piping compound. A
battery requires one or two connections of appropriate size for the gas requirement.
VULCAN-HART
F-31233 Rev. K (February 2011)
-7-
GRM SERIES GAS FRYERS
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 (ALL MODELS):
The gas pressure should be set at 4” W.C. (Water Column) (0.8 kPa) for natural gas and
10” W.C. (2.75 kPa) for propane gas. If incoming pressure exceeds ½ PSI (3.45 kPa), an
additional pressure regulator must be installed.
TESTING THE GAS SUPPLY PIPING SYSTEM:
When test pressures exceed ½ PSI (3.45 kPa), the fryer and its individual shutoff valve
must be disconnected from the gas supply piping system.
When test pressures are ½ PSI (3.45 kPa) or less, the fryer must be isolated from the gas
supply piping system by closing its individual shutoff valve.
Fryers with Casters:
Separate instructions for installing casters are included with the casters:

The installation shall be made with a connector that complies with the
Standard for Connectors for Movable Gas Appliances, ANSI Z21.69, CAN/CGA6.16, and a quick-disconnect device that complies with the Standard for QuickDisconnect Devices for Use with Gas Fuel, ANSI z21.41 CSA 6.9 or QuickDisconnect Devices for Use with Gas Fuel,

When installing a quick disconnect you must also install a means for
limiting the movement of the fryer. This device will prevent the gas line or quick
disconnect from being strained. The restraining device should be attached to
the cutout on the back panel. See illustration for location.
VULCAN-HART
F-31233 Rev. K (February 2011)

GRM SERIES GAS FRYERS

The fryer must be installed with a connector (not supplied by Vulcan) complying
with the above codes.

The fryer must be installed with restraining means to guard against transmission of
strain to the connector. See illustration.

The fryer must be installed with the casters provided.

If the restraint is ever to be disconnected, first turn the gas supply off.
LEVELING THE FRYER
Check the level of the fryer by placing a level on top of the fryer after gas connections
have been made.
Ensure that the fryer is level front-to-back and side-to-side in the final installed position.
Lock the wheels after unit is level.
OPERATION
Hot oil and parts can cause burns. Use care when operating,
cleaning and servicing the fryer.
Spilling hot frying compound can cause severe burns. Do not move
fryer without draining all frying compound from the tank.
OVER-TEMPERATURE SHUTDOWN
If the shortening becomes overheated, a high-temperature shutoff device will turn the gas
valve off and extinguish the pilot.
If the fryer shuts down due to overheating, DO NOT relight the pilot until the shortening
temperature is below 300 F (149 C).

Never run water or boil out solution through filter and motor / pump. Doing so
will void your fryer warranty.
Solid shortening should NOT be used with GRM fryers. Melting solid
shortening will damage the tank and void your warranty.
FILTERING PROCEDURE WHEN USING LIQUID SHORTENING:
Oil Temperature should be 300-350° F. Use the provided crumb scoop to remove and suspend
crumbs on the bottom of the tank before proceeding to Step 1.
1. Turn the Fryer temperature knob to the OFF position.
Do NOT heat the fryer during the filtering procedure. Permanent damage to your
fry tank may occur and warranty may be voided.
2. Vulcan recommends adding an oil treatment media to the oil prior to filtering.
3. Turn the Filter Power switch to the ON position. Make sure that the filter drawer is closed
completely and that the suction tube and receptacle block are in the correct position. Fig. 5

4. Drain the oil out of the fry tank by turning the red handle drain valve. The filter pan will begin
to fill with oil. When the oil level fills half of the filter pan, pull the red handled filter lever
towards you. The motor / pump will begin and oil will flow back into the fry tank. The oil will
flow into the back of the tank towards the front and down the drain back into the filter pan.
Use the provided filter brush to help wash down the residue from the bottom and sides of the
fry tank and allow it to flow down into the filter pan.
5. Close the red handle drain valve turning off the flow of oil into the filter pan. The fry tank will
begin to fill. It is normal to see air bubbles in the tank towards the end of filtering. The motor
/ pump sound will change when the filter pan is empty of oil. Push in the red filter handle
lever and turn the power switch OFF.
6. The oil level is correct when it is between the Min / Max lines on the fry tank.
7. Turn the Thermostat knob to the desired temperature. Burners should turn on and the oil
should begin to heat.
8. Repeat this procedure for the remaining tank(s) in the battery.
9. When finished filtering, clean all of the filter components as in step 1 under Assembly
section.
FILTERING TIP:
Open the filtering drawer approximately 1” to allow any oil in the return line to run back into the filter
pan. This will take about 30 seconds to complete. Then open the drawer completely to clean filter
components.
REMOVING EXCESS DEBRIS FROM THE FILTER:
1. Pull the filter drawer out and remove the crumb basket and empty any debris into the trash.
2. Remove the filter screen assembly. Scrape debris from the filter screen. Then remove the
insert by unlatching the latch. Clean all parts thoroughly as mentioned in the Assembly
section on page 17.
3. Scrape debris from the bottom of the filter pan and discard in the trash. Clean all parts
thoroughly as mentioned in the Assembly section on page 17. Clean all parts thoroughly as
mentioned in the Assembly section on page 17.
4. Reassemble all filter components after being dried thoroughly as in the Assembly section on
page 17.

FLUSH AND DISCARD:
1. Follow filtering instructions 1-3, however do not put oil treatment media into the fryer. Drain
the fryer oil into the filter pan.
2. Attach the quick disconnect hose to the discard male quick disconnect fitting.
3. Place other end of the discard hose into a container that is large enough to retain the
discarded shortening.
4. To start the discard operation, turn Power Switch ON.
5. Pull the Yellow Discard Handle Lever Rod towards you and the Motor/Pump will begin to
operate. NOTE: Oil will come out immediately out of the nozzle end of the hose.
6. Once the oil has been discarded completely and the filter pan is empty, push the Discard
Lever back in. The Motor/Pump will stop and turn the Power Switch OFF.
7. Disconnect the discard hose. Be careful to let the hose drain before putting away. Close the
drain valve and fill the fry tank with new oil.
BOIL OUT PROCEDURE:
Use the Boil Out By-Pass™ drain extension allowing the boil
out solution to exit the fry tank without using the filtering
system. Do NOT allow water to run through the motor / pump.
Drain the boil out solution into a bucket or place a high
temperature rated water hose on the end of the drain extension
allowing the other end to flow into a floor drain. In Fig. 6 the
arrow is pointing to the drain extension. It is threaded into the
top coupling of the oil drain tube. Drain extension needs to be
only hand tightened.

THERMAL OVERLOAD PROTECTION BUTTON:
The motor/pump supplied with the filtering system
has a thermal overload protection circuit that senses
when excess heat occurs due to filtering for long
periods of time or under heavy load prior to
discarding debris buildup. If the thermal overload
protection is tripped, wait 5 minutes and then reset
the motor by pushing in the red button. The arrow in
Figure 7 shows the location of the reset button;
located on the front off the motor / pump facing
towards you.
