CHAPTER 1: GENERAL INFORMATION
1.4 Equipment Description
H50 Series high-efficiency gas fryers employ a unique infrared burner system that uses up to 43%
less energy to cook the same volume as conventional fryers. Models in this series include MJH50,
FMH50, and FPH50 variants. MJH50 variants have no built-in filtration system. FMH50 variants
have a built-in Filter Magic II filtration system. The Filter Magic system is housed in its own cabinet, which may be attached to either side of a fryer and which can be located anywhere in a battery of
fryers. The FPH50 variants have a built-in FootPrint III filtration system that is located underneath
the fryer to conserve floor space. (In batteries of fryers, the FootPrint III syste m is always loc ated
under the leftmost two fryers.)
All H50 Series fryers are of an open-pot design with no tubes and have a hand-sized opening into the
deep cold zone, which makes cleaning the stainless frypot quick and easy.
Frypots are constructed of welded, heavy-gauge stainless steel, and may be configured with a single
(full) vat or dual vats. A drain valve is tapped into the center of the frypot, with a front-operated
manual ball valve. Heating is supplied by a pair of infrared burner assemblies mounted on each side
of the frypot. Combustion air for the burners is supplied by a dedicated blower mounted on the front
of the frypot. H50 Series fryers can be configured for natural gas, propane (LP), or manufactured
gas, as required by the customer.
Each frypot is equipped with a temperature probe for precise temperature control. The probe is located on the centerline of the frypot for rapid response to changes in loads, and to provide the most
accurate temperature measurement.
All H50 Series fryers come standard with electronic ignition, melt cycle, and boil-out mode. Control

CHAPTER 2: INSTALLATION INSTRUCTIONS
2.1 General Installation Requirements
PROPER INSTALLATION IS ESSENTIAL FOR EFFICIENT, TROUBLE-FREE OPERATION OF YOUR
FRYER. ANY UNAUTHORIZED ALTERATIONS MADE TO THIS EQUIPMENT W ILL VOID THE FRYM AS-
WARRANTY.
TER
Upon arrival, inspect the fryer carefully for visible or concealed damage. (See Shipping Damage
Claim Procedure in Chapter 1.)
CLEARANCE AND VENTILATION
The fryer(s) must be installed with a 6” (150 mm) clearance at both sides and back when installed
adjacent to combustible construction; no clearance is required when installed adjacent to noncombustible construction. A minimum of 24” (600 mm) clearance should be provided at the front of the
fryer.
One of the most important considerations of efficient fryer operation is ventilation. Make sure the
fryer is installed so that products of combustion are removed efficiently, and that the kitchen ventilation system does not produce drafts that interfere with proper burner operation.
The fryer flue opening must not be placed close to the intake of the exhaust fan, and the fryer must
never have its flue extended in a “chimney” fashion. An extended flue will change the combustion
characteristics of the fryer, causing longer recovery time. It also frequently causes delayed ignition.
To provide the airflow necessary for good combustion and burner operation, the areas surrounding
the fryer front, sides, and rear must be kept clear and unobstructed.
Fryers must be installed in an area with an adequate air supply and adequate ventilation. Adequate
distances must be maintained from the flue outlet of the fryer to the lower edge of the ventilation
filter bank. Filters should be installed at an angle of 45º. Place a drip tray beneath the lowest edge of
the filter. For U.S. installation, NFPA standard No. 96 states, “A minimum distance of 18 in. (450
mm) should be maintained between the flue outlet and the lower edge of the grease filter.”
Frymaster recommends that the minimum distance be 24 in. (600 mm) from the flue outlet to the
bottom edge of the filter when the appliance consumes more than 120,000 BTU per hour.
For installations in the United States, information on construction and installation of ventilating
hoods can be found in the NFPA standard cited above. A copy of the standard may be obtained from
the National Fire Protection Association, Battery March Park, Quincy, MA 02269.
DANGER
Do not attach an apron drainboard to a single fryer. The fryer may become unstable,
tip over, and cause injury. The appliance area must be kept free and clear of com-
bustible material at all times.
2-1
H50 SERIES GAS FRYERS
CHAPTER 2: INSTALLATION INSTRUCTIONS
NATIONAL CODE REQUIREMENTS
The type of gas for which the fryer is equipped is stamped on the data plate attached to the inside of

propane gas, and those stamped “MFG” only to manufactured gas.
Installation shall be made with a gas connector that complies with national and local codes, and,
where applicable, CE codes. Quick-disconnect devices, if used, shall likewise comply with national,
local, and, if applicable, CE codes.
ELECTRICAL GROUNDING REQUIREMENTS
All electrically operated appliances must be grounded in accordance with all applicable national and
local codes, and, where applicable, CE codes. A wiring diagram is located on the inside of the fryer
door. Refer to the rating plate on the inside of the fryer door for proper voltages.
DANGER
If this appliance is equipped with a three-prong (grounding) plug, it must be plugged
directly into a properly grounded receptacle.
Do not cut or remove the grounding prong from the plug.
DANGER
This equipment requires electrical power for operation.
Place the gas control valve in the OFF position in case of a prolonged power outage.

FCC COMPLIANCE
The user is cautioned that any changes or modifications to Frymaster computers not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Frymaster computers have been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. Whil e these devices are verified as C lass A devices, t hey
have been shown to meet the Class B limits. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of the equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.

CHAPTER 2: INSTALLATION INSTRUCTIONS
If necessary, the user should consult the dealer or an experienced radio and television technician for
additional suggestions.
The user may find the booklet “How to Identify and Resolve Radio-TV Interference Problems” helpful. It is prepared by the Federal Communications Commission and is available from the U.S. Government Printing Office, Washington, DC 20402, Stock No. 004-000-00345-4.
2.2 Caster/Leg Installation
Depending upon the specific configuration ordered your fryer may have been shipped without installed casters or legs. If casters or legs are installed, you may skip this section and proceed to section 2.3, Pre-Connection Preparations.
If your fryer requires the installation of casters/legs, install them in accordance with the instructions included in your accessory package.
2.3 Pre-Connection Preparations
DANGER
Do not connect fryer to gas supply before completing each step
in this section.
After the fryer has been positioned under the fry station exhaust hood, ensure the following has been
accomplished:
1. Adequate means must be provided to limit the movement of fryers without depending upon the
gas line connections. If a flexible gas hose is used, a restraining cable must be connected at all
times when the fryer is in use. The restraining cable and installation instructions are packed with
the flexible hose in the accessories box that was shipped with your unit.
2. Single unit fryers must be stabilized by installing restraining chains on fryers equipped with
casters or anchor straps on fryers equipped with legs. Follow the instructions shipped with the
casters/legs to properly install the chains or straps.
3. Level fryers equipped with legs by screwing out the legs approximately 1 inch then adjusting them so that the fryer is level and at the proper height in the exhaust hood. Frymaster
recommends that the minimum distance from the flue outlet to the bottom edge of the hood be 24 in. (600 mm) when the appliance consumes more than 120,000 BTU per hour.
NOTE: There are no built-in leveling devices on fryers equipped with casters. The floor where the fryer is to be installed must be level.
4. Test the fryer electrical system:
a. Plug the fryer electrical cord(s) into a grounded electrical receptacle.
b. Place the power switch in the ON position.
• For fryers equipped with analog controls, verify that the power and heat lights are lit.

CHAPTER 2: INSTALLATION INSTRUCTIONS
* For distances of more than 20 feet (6 m) and/or more
than 4 fittings or elbows, increase the connection by one
pipe size.
Before connecting new pipe to your unit, the pipe must be thoroughly blown out to remove any foreign particles. If these foreign particles get into the burner and controls, they will cause improper
and sometimes dangerous operation.
CE Standard
Required airflow for the combustion air supply is 2m3/h per kW.
1. Connect the quick-disconnect hose to the fryer quick-disconnect fitting under the front of the
fryer and to the building gas line.
NOTE: Some fryers are configured for a rigid connection to the gas supply line. These units are
connected to the gas supply line at the rear of the unit.
When using thread compound, use very small amounts on male threads only. Use a pipe thread
compound that is not affected by the chemical action of LP gases (Loctite™ PST56765 Sealant is
one such compound). DO NOT apply compound to the first two threads. This will ensure that
the burner orifices and control valve do not become clogged.
2. Open the gas supply to the fryer and check all piping, fittings, and gas connections for leaks. A
soap solution should be used for this purpose.
DANGER
Never use matches, candles, or any other ignition source to check for leaks.
If gas odors are detected, shut off the gas supply to the fryer
at the main shut-off valve and contact the local gas company or an authorized
service agency for service.
3. Close the fryer drain valve and fill the frypot with water and boil-out solution to the bottom OILLEVEL line at the rear of the frypot. Light the fryer and perform the boil-out procedures that are
described in the “Lighting Instructions” and “Boiling Out the Frypot” topics found in Chapter 3
of this manual.
WARNING
“Dry-firing” your unit will cause damage to the frypot. Always ensure that melted
shortening, cooking oil, or water and boil-out solution is in the frypot before firing
your unit for any extended period.

The optimum burn is a bright orange-red glow. If a blue flame is observed, or if there are dark
spots on a burner face, the air/gas mix requires adjustment. Adjustment procedures are different
for CE and Non-CE units.
Adjusting Air/Gas Mix:
Non-CE Units and CE Units Built After April 1999
On the side of the blower housing opposite the motor is a plate with one or two locking nuts. Loosen
the nut(s) enough to allow the plate to be moved, then adjust the position of the plate to open or close
the air intake opening until a bright orange-red glow is obtained. Carefully hold the plate in position
and tighten the locking nut(s).
Adjusting Air/Gas Mix:
CE Units Built Before May 1999
CE units built before May 1999 are equipped with a shield assembly in front of the blowers. An air
shutter plate on the face of the shield assembly regulates the amount of airflow to the blower intake.
To adjust the shutter plate, loosen the locking screws and slide the shutter to the left or right as necessary to obtain a bright orange-red glow. Carefully hold the shutter plate in position and tighten the
locking screws.

boils over, turn off power to the fryer immediately and let the solution cool for a few
minutes before resuming the process.
4. After the solution simmers for 1 hour, turn the fryer off, allow the solution to cool, then add 2
gallons (7.75 liters) of cold water and stir. Drain the solution into a suitable container and clean
the frypot thoroughly.
WARNING
Do not drain boil-out solution into the built-in filtration system. Doing so may cause
damage to the filtration pump.
5. Rinse the frypot at least twice by filling the frypot with clean water and draining. Dry the frypot
thoroughly with a clean, dry towel.
DANGER

Like th e C omp ut er Mag ic III, th e a nal og con tr ol le r utilizes a frypot-mounted temperature probe and
solid-state electronics mounted on the control panel. The temperature probe is connected to the control circuitry via an interface board behind the control panel. Rotating the Temperature Knob to the
desired temperature sets the cooking temperature. When the Power Switch is placed in the ON posi-
tion, electrical current is supplied to the fryer’s components and the Power On Light illuminates.
Placing the Melt Cycle Switch in the ON position causes the burners to cycle on for a few seconds
and off for a longer period until the temperature in the frypot reaches 180ºF (82ºC). At that time the
unit automatically enters the heat mode, causing the burners to remain lit until the setpoint is
reached. When in the melt cycle, the Melt Cycle Light
will alternately illuminate and go out as
the burners cycle on and off.
CAUTION
Do not cancel the Melt Cycle if solid shortening is being used.
When the unit enters the heat mode, the Heat Mode Light will illuminate and remain on until the
setpoint is reached.
The Trouble Light ? will illuminate if there is an ignition failure. To reset the controller after an
ignition failure, place the Power switch in the OFF position for 30 seconds, then place it back in the
ON position. The Trouble Light is also used to indicate the presence of a probe circuit or high-limit
circuit problem.

On the digital controller, the thermostat knob has been replaced with a digital display and a pair of
keys for increasing or decreasing the setpoint.
Pressing the ON/OFF Switch
supplies electrical power to the fryer, and causes the controller
software version number to display for 4 seconds in the Digital Display. Following the software version number display, the SETPOINT TEMPERATURE WILL DISPLAY CONSTANTLY. Pressing
the Temperature/Setpoint Display Switch will display the actual frypot temperature.
The fryer will automatically enter the melt cycle mode and will continue to cycle on for a few
seconds and off for a longer period until the temperature in the frypot reaches 180ºF (82ºC). At that
time, it will enter the heat mode. The purpose of the melt cycle is to gradually melt solid shortening
to prevent its scorching, and to prevent creation of “hot spots” on the frypot. To cancel the melt
cycle, press the Melt Cycle Switch .
CAUTION
Do not cancel the Melt Cycle if solid shortening is being used.
NOTE: If solid shortening is not being used, the controller can be programmed to bypass the Melt
Cycle as follows: With the controller in the OFF mode, press the Melt Cycle Switch . The
display will show either a “0” (meaning that the melt cycle can be bypassed) or a “1” (meaning that
