Gas Supply
The local gas authority should be consulted at the installation planning stage in order to establish the availability
of an adequate supply of gas and to ensure that the meter is adequate for the required flow rate. The pipe work
from the meter to the appliance must be an appropriate size.
All fixed (non-mobile) appliances must be fitted with an accessible upstream gas shutoff valve as a means of
isolating the appliance for emergency shut off and for servicing. A union or similar means of disconnection must
be provided between the gas-cock and the appliance.
A manually operable valve must be fitted to the gas supply to the kitchen to enable it to be isolated in an
emergency. Wherever practical, this shall be located either outside the kitchen or near an exit in a readily
accessible position.
Where it is not practical to do this, an automatic isolation valve system should be fitted which can be operated
from a readily accessible position near the exit.
In locations where the manual isolation valve is fitted or the automatic system can be reset this notice must be
posted:
“ALL DOWNSTREAM BURNER AND PILOT VALVES MUST BE TURNED OFF PRIOR TO
ATTEMPTING TO RESTORE THE SUPPLY. AFTER EXTENDED SHUT OFF, PURGE
BEFORE RESTORING GAS”
NOTE: Before assembly and connection, check gas supply.
Gas Supply Notes
1) The type of gas for which the unit is equipped is stamped on the rating plate, see locations on page 9.
Connect a unit stamped “NAT” only to natural gas and stamped “LP” only to propane gas.
2) If it is a new installation, have the gas authorities check the meter size and piping to assure that the unit
is supplied with the necessary amount of gas supply and pressure to operate the unit(s).
3) Make certain new piping and connections have been made in a clean manner and have been purged so
that piping compound, chips, etc. will not clog pilots, valves, gas regulator, or burners. Use pipe joint
compound approved for natural and liquefied petroleum gases.
4) The natural gas pressure coming into the regulator should be 7” WC or .25 psig (1.75kpa) and 4” WC
.14 psig (1.0 kpa) coming out of the regulator. For liquid propane gas pressure coming into the
regulator should be 11” WC or .4 psig (2.75kpa) and 10” WC .36 psig (2.5kpa) coming out of the
regulator.

Gas Pressure Regulator
A gas pressure regulator must be installed to regulate the proper flow of gas to the appliance. The regulator must
be installed between the main gas supply line to the unit shut off valve and the appliance and must be accessible
for servicing. Proper sizing of the regulator is extremely important, check the BTU rating of the appliance or
appliances being regulated by the regulator.
NOTE: Contact the factory for regulator sizing when multiple appliances are being installed in a line up or
island suite configuration and are interconnected using the front manifold connections.
NOTE: Gas pressure should be checked when the unit is installed and all other equipment on the same line is
on. The operating gas pressure must be the same as that specified on the rating plate. If necessary,
pressure adjustment may be made at the pressure regulator.
The appliance and its individual shutoff valve must be disconnected from the gas supply piping system
during any pressure testing of that system where pressures are in excess of .5 psig (3.45kpa).
When test pressures are .5 psig (3.45kpa) or less, the appliance must be isolated from the gas
supply system by closing its individual manual shutoff valve.
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, all piping receiving gas should be fully purged to remove air.
Ventilation Air / Flue Connections
The following notes are intended to give general guidance. For detailed recommendations, refer to the
applicable codes in the Country, State, County and City of installation.
Do not obstruct the flow of combustion and ventilation air.
Proper ventilation is critical for optimum performance. The ideal method of ventilating gas fired equipment is
the use of properly designed canopy that should extend six inches (152mm) beyond all sides of the appliance (s)
and six feet six inches (1981mm) above the floor. Information on the construction and installation of ventilating
hoods may be obtained from the standard for "Vapor Removal from Cooking Equipment," NFPA No. 96 (latest
edition), available from the National Fire Protection Association, on their web site: http://www.nfpa.org/.
A strong exhaust will create a vacuum in the room. For an exhaust vent to work properly, replacement air must
be equal to the amount of air exhausted. An imbalance between exhaust and replacement air can cause
degradation in the appliance’s performance.
All gas burners and pilots need sufficient air to operate. Large objects should not be placed in front of the
appliance(s) that would obstruct the flow of air into the front.
NOTICE:
In the Commonwealth of Massachusetts all gas appliances vented by either mechanical systems
or ventilation hoods shall comply with 248 CMR interlocking requirements.

Operating Instructions
Lighting Instructions
Fryer Section
Before turning the burner on
LIGHTING INSTRUCTIONS are located on the inside of the cabinet door.
1. Fill the vessel with liquid oil up to the "Level" marking.
2. Do not operate fryer without oil in the vessel.
3. Do not overfill the vessel.
LIGHTING
1. Set thermostat dial and gas valve dial to the “OFF” position. Wait 5 minutes and turn gas valve dial to
“PILOT” position.
2. Depress the gas valve dial for 5-15 seconds to purge the gas line, and then light the pilot with a log lighter or
match. Continue to depress the dial for about 30 seconds or until the pilot remains lit. Release the dial, the
pilot should remain lit. Repeat as needed until the pilot remains lit.
3. To light the burners, turn the gas valve dial to the “ON” position and turn thermostat to the desired
temperature.
4. For daily shutoff, turn the thermostat dial and gas valve dial to the “OFF” position.
Pilot
A 5 minute complete shutoff period is
required before the appliance is re-lighted
FRYING WITH SHORTENING
To deep fry with shortening, always start with an empty and/or cleaned-out tank and melt the shortening on the
stove – carefully pouring it into the tank. That way, you can be sure the shortening is in full contact with the
fryer tank metal – eliminating the potential of weld fracture from dry firing.
For daily shutoff: If you do not want to relight the pilot the next day, turn thermostat dial “OFF” and gas
valve dial to the “PILOT” position, pilot(s) will remain on.

Cleaning and Maintenance
Gas Fired Appliances
1. Shut down the fryer by turning the thermostat and pilot valve to the OFF position.
2. Disconnect the restraining device before moving the appliance for cleaning and servicing.
3. Drain the fryer into a filtered pan or steel container. Flush out sediment at the bottom of fryer with liquid oil.
4. Close the drain valve and fill the vessel with a mixture of boil-out solution and water.
5. Relight the pilot and turn on the burners.
6. When the solution starts to boil, turn off the thermostat and let the vessel soak to soften deposits and/or
carbon spots, for approximately one hour.
7. Drain off the solution. Scrub the insides with a brush and rinse thoroughly.
8. Repeat steps 4-7 if necessary.
9. Wipe dry with soft towels and refill with oil/shortening.
NOTE: STAINLESS STEEL PARTS - Do not use steel wool, abrasive cloths, cleaners or powders to clean
Stainless Steel surfaces. All stainless Steel parts should be wiped regularly with hot soapy water during
the day and a Stainless Steel cleaner at end of the day. To remove encrusted materials, soak in hot
water to loosen the material - then use a wood or nylon scraper.
All water must be removed before adding oil or shortening. Not doing so can
result in splattering of hot oil causing severe burns and burn hazard.
DO NOT DRY-FIRE; operating the unit without liquid is an extreme fire hazard
and will cause irreparable damage such as gas leaks, scorched surfaces and burnt
components. Dry firing is typically done after cleaning when the end user wants to
dry out the tank the "easy" way. It is a major cause of tank damage in the industry.
1. Do not drain the oil while it’s hot; wait until it cools before emptying. Rapid
change in temperature causes stress fractures and tears at the seams of the tank.
2. Do not use acidic cleaners; use only boil-out solution. Acid can cause erosion to
metal and in due time can cause a leak in the tank.
3. Solid shortening must be liquefied before filling the tank. The tank walls must
have liquid against it in order to transfer heat and avoid overheating and stressing
the metal to the point of a tear.
4. Do not rinse off a hot tank with cold water. Always allow it to cool first.
5. Do not use sharp tools to clean the fryer; it can leave metal debris in the tank.
6. Keep your tank clean. Check for debris buildup at the bottom of the tank, and
never allow too much build-up to occur. Excessive build up reduces the
efficiency of the fryer.
