GRDF / GRCF SERIES GAS FRYERS
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.
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
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.

GRDF / GRCF SERIES GAS FRYERS
FILTERING THE OIL
Hot oil and hot parts can cause burns. Use care when operating,
cleaning, and servicing the fryer.
Filter shortening at least once a day.
1. Do NOT turn off the power to the fryer. Leave power on.
2. Insert the drain extension into the drain valve. Tighten only hand tight.
3. Direct the drain extension into the mobile filtering device that you want to use.
4. A cold fryer will not drain properly. Always filter shortening between 250°F
and 350°F. 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.
5. Use the provided crumb scoop to remove the heavy debris lying on the bottom
of the tank.
6. Slowly open the drain valve to allow oil to flow from the fry tank to the filter pan.
Then open the drain valve all the way. Please note the gas burners will
automatically turn off at this point and DRAINING will appear on the digital
display for solid state models and DRAINING OIL will display on computer
models.
7. When fry tank is empty use the tank brush to remove any additional debris.
8. Close the drain valve. The display will change to; FILL TANK for solid state
models and FILL TANK for computer models.
9. Fill tank with new shortening. Fill to a minimum of the MIN level but no high that
halfway between MIN and MAX. Oil will expand as it is heated.
10. Press the Temp button on the display. The display will ask if the tank is full;
TANK FULL.
11. Press the TEMP button on the display a second time to confirm that the oil level
is correct in the fry tank. Once pressed, the gas burners will ignite and begin
heating the oil to desired temperature.
DRAINING THE TANK
1. Turn off fryer.
2. Insert the drain extension into the drain valve. Tighten only hand tight.

GRDF / GRCF SERIES GAS FRYERS
3. Direct the drain spout into the container that you want to drain the shortening into.
4. Open the drain valve. The oil will drain into the container. When the container is
full or the fryer tank is empty, close the drain valve. Repeat this step until the fryer
is empty. Remove the drain extension and place it back into the provided holder.
5. It is recommended to now Boil Out your fry tank. Follow the Boil Out procedure.
Then perform the weekly clean-out as described under CLEANING.
6. Once tank is completely empty, boiled out and cleaned, add new shortening. Turn
on the power switch to begin heating the oil to desired temperature.
BOIL OUT PROCEDURE
Weekly or when oil is replaced:
1. Drain the tank as described under FILTERING THE OIL and instead of replacing
the shortening with new oil fill with water
2. Close the drain valve and fill tank with water. Use recommended Vulcan’s Boil-Out
solid degreaser low foaming cleaner tablets part number 956812-1 which can be
ordered from your local dealer. Follow the instructions on the side of the package.
Do not use chlorine or sulfate/sulfide cleaners.
3. Solution level must be between the MIN and MAX levels on the fryer tank.
4. After pressing the TEMP button for the second time confirming that the boil out
solution level is correct the gas burners will begin to heat the water solution. The
fryer controls will be able to sense that there is a water mix solution vs. oil and will
automatically set the correct temperature. There is NO need to change the set
temperature from the last set operating temperature. Allow solution to simmer for
about 15 to 20 minutes. Use a tank brush to clean the sides, back, front, and heat
exchanger tubes.
5. With the drain extension tightened into the drain valve, drain and discard the
cleaning solution from the tank.
6. Close the drain valve and refill the tank with water. Add 1 cup (1/4 L) of vinegar to
neutralize alkaline left by the cleaner. Solution level must be between the MIN and
MAX level on the fryer tank. Press the TEMP button to confirm the vinegar level is
correct.
7. Press the TEMP button again and the gas burners will heat the solution. Bring the
solution to a simmer only. Allow to stand for a few minutes.

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.
Š
Use a damp cloth with warm water and a mild soap or detergent.
Do not use chlorine or sulfate/sulfide cleaners.
Š
Š
Rinse thoroughly, and then polish with a soft dry cloth.
Keep the fryer exterior clean and free of accumulated grease to prevent
stubborn stains from forming. If regular cleaning is neglected, grease will be
burned on and discolorations may form.
Š
Š
Remove discolorations by washing with any detergent or soap and water.
Use a self-soaping, non-metallic scouring pad for particularly stubborn
discolorations.
Š
Š
Always rub with the grain of the stainless steel.
Do not use a metallic scoring pad or harsh cleaners.

Filtering Instructions for KleenScreen PLUS® Fryers
General
The KleenScreen PLUS® filtration system filters the oil as it is pumped back into its’ respective
tank(s). Only one tank can be drained and filtered at a time. Under no circumstances should both
tanks be drained at the same time.
Assembly
•
After unpacking, wash the filter pan, crumb basket and filter screen assembly. Make sure
you remove the insert located inside the filter screen. Use dishwashing detergent and warm
water, (parts are dishwasher safe). Rinse the filter pan, crumb basket and filter screen
components completely and wipe all parts dry with a clean cloth.
•
•
Pull out the filter drawer all the way leaving the filter pan opening exposed.
Place the filter tank into the filter drawer making sure that the pins on the bottom of the filter
pan line up with the holes in the filter drawer. Position the filter screen assembly into the
suction tube clip in the filter pan positioning the filter screen assembly flat on the bottom of
the filter pan. Place the primary crumb basket onto the left handle of the filter pan.
•
Carefully line up the suction tube nozzle so that it mates with the oil receptacle block
mounted on the frame of the fryer battery. Close the drawer. See Figures 1, 2 3 and 4.

INSTRUCTIONS TO REMOVE & REPLACE KLEENSCREEN PLUS® FILTER ENVELOPE
FOR ABSOLUTE FILTRATION & MAXIMUM FLOW RATE WE RECOMMEND YOU CHANGE YOUR FILTER
ENVELOPES AT EVERY OIL CHANGE (10-14 DAYS DEPENDING ON OIL USAGE).
Step 1
Discard all oil from the filter vessel, (see pages 23 or 24). When the
filter pan is empty, use a spatula and scrape off all debris left on the
filter envelope and in the filter pan.
Step 2
Unscrew “S” Tube from filter by turning the Bottom Knurled fitting
counter- clockwise.
Step 3
Remove SST Closure Clip by lifting off one side.
Step 4
Remove SST Filter Screen Insert and wash insert with hot water and
dry thoroughly. The Filter Screen Insert is dishwasher safe. Place the
insert into a new KleenScreen PLUS® Filter envelope.
DO NOT WASH FABRIC ENVELOPE
Step 5
Place Filter Screen Insert into the fabric envelope making sure that the
holes line up. Fold over the other end of the envelope and place SST
Closure Clip on – hinge over and firmly press clip all the way down to
secure and seal filter assembly. Making sure that the folded end is face
down; screw “S” Tube Assembly onto the Filter Assembly. Tighten the
Bottom Knurled fitting. When tightened, the “S” Tube assembly should
be perpendicular to the long side of the filter assembly.
Step 6
Reposition the filter tube into the provided clip. Align filter tube so that
the end of the “S” Tube engages the Oil Receptacle fitting each time the
drawer is opened and closed.

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.
FILTERING PROCEDURE
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. Do not turn off the Fryer. The power must be on throughout the entire filtering process.
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. Make sure that the filter drawer is closed completely and that the suction tube and
receptacle block are in the correct position. Fig. 5

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 SCREEN 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 19.
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 19. Clean all parts thoroughly as
mentioned in the Assembly section on page 19.
4. Reassemble all filter components after being dried thoroughly as in the Assembly section on
page 19.
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.
Fig. 6
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.
