GBD_GBDF 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.

Š
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.  
Š
In Australia, use only the caster supplied by the manufacturer for the fryer  
device. The fryer must be installed using a hose assembly restraining device to  
limit the movement of the appliance in accordance with AS1869.  
Š
Š
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.  
Š
Š
The fryer must be installed with the casters provided.  
If the restraint is ever to be disconnected, first turn the gas supply off.  
ELECTRICAL CONNECTION  
Š
The fryer comes with a NEMA 15-5P plug that requires 120 Volt service. Plug in the  
wire connection into an approved outlet.

GBD_GBDF SERIES GAS FRYERS  
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.  
If using casters, 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 turn fryer on until the shortening  
temperature is below 300°F (149°C).  
If an overheating situation persists, contact your local Vulcan-Hart authorized service  
office.  
BEFORE FIRST USE  
Cleaning  
New units are wiped down at the factory to remove any visible signs of dirt, oil, grease,  
etc. remaining from the manufacturing process.  
Before any food preparation, thoroughly wash the protective oil from all surface parts and  
the tank interior with hot soapy water to remove any film residue and dust or debris.  
Do not use chlorine or sulfate/sulfide cleaners.  
Š
Wash any accessories shipped with unit.  
Rinse fryer and accessories thoroughly and drain the fryer.  
Wipe tank completely dry with a soft, clean cloth.

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.  
3. Scrape debris from the bottom of the filter pan and discard in the trash.  
4. Reassemble all filter components after being dried thoroughly.  
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. With the power switch still ON; pull the Yellow Discard Handle Lever Rod towards you.  
Press the FILTER switch and the Motor/Pump will begin to operate. NOTE: Oil will come out  
immediately out of the nozzle end of the hose.  
5. Once the oil has been discarded completely and the filter pan is empty, push the Discard  
Lever back in. Press the FILTER switch to the OFF position to stop motor/pump.  
6. Disconnect the discard hose. The hose connection will be hot due to the temperature of the  
oil that was discarded. 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.
