CAN/CSA-B149.2 Propane Installation Code (latest edition), available from the
Canadian Gas Association 178 Rexdale Blvd., Etobicoke, Ontario Canada
M9W 1R3.
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:
Š
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.
Š
Š
Š
Locate the fryer under a hood with adequate connection to an exhaust
duct. 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.
Š
Š
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.
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.

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:
Š
Š
The installation shall be made with a connector that complies with the
Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 or
Connectors for Moveable Gas Appliances, CAN/CGA-6.16, and a quick-
disconnect device that complies with the Standard for Quick-Disconnect
Devices for Use with Gas Fuel, ANSI z21.41 or Quick-Disconnect Devices for
Use with Gas Fuel, CANI-6.9.
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.

DAILY FILTERING
Hot oil and hot parts can cause burns. Use care when operating,
cleaning, and servicing the fryer.
Š Filter shortening at least once a day. Refer to the instructions provided
with your filtering equipment.
Š A cold fryer will not drain properly. Always filter shortening between 250F
and 350F. The shortening in the cold zone area will remain hard if the heat is only
on for a few minutes. If necessary, use the clean-out rod to carefully stir the hard
shortening to an area above the cold zone where it will melt. Use the tank brush to
help clear sides and tubes of debris.
CLEANING
Hot oil and hot parts can cause burns. Use care when operating,
cleaning, and servicing the fryer.
Daily
Clean your fryer regularly with the tank brush along 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.
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.
Š
Clean all exterior surfaces of your fryer at least once daily.

GRM SERIES GAS FRYERS
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.
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, (hose not
supplied with fryer – Accessory Option).
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 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.
