1. GENERAL INFORMATION

1.1. DESCRIPTION

The Ultrafryer® 14₺ IRC premix gas fryer was designed by Ultrafryer Systems® to operate as an energy-
efficient, gas-fryer and is design-certified by the Canadian Standards Association (CSA) and the
National Sanitation Foundation (NSF). It is manufactured to operate on either NATURAL or PROPANE
gas according to the following Operational Requirements. Each fryer is shipped completely
assembled with the accessories packed inside the fryer vat and each fryer has been adjusted, tested
and inspected prior to shipment. This gas fryer is designed to be used in a commercial food
preparation environment after it is properly installed as outlined in this manual.

1.2. SAFETY

The major safety concern associated with the Ultrafryer® Infrared Premix Gas fryer is burns from hot
shortening. In order to prevent serious burns, good housekeeping habits are required. The floor in
front of and the area around the fryer should be kept clean and dry. Whenever anything is placed into
a fryer vat, care should be used not to splash the hot shortening. Product should always be “PLACED”
into the shortening, NOT THROWN. Safety goggles, neoprene insulated gloves, and an apron must be
worn while boiling-out a fryer vat.

Electrical controls used in the gas fryer operate on 120 volts single phase electrical power, and no
adjustments or replacement of electrical controls should ever be attempted without first
disconnecting electrical power. The fryer should never be operated with wet hands or while standing
in water. To do so can result in serious electrical shock or death.

1.3. AUTOMATIC SAFETY FEATURES

This fryer is equipped with the following Automatic Safety Features:

1. High Limit thermostat to shut off gas to the main burners by operating a solenoid-activated

safety valve in the combination gas control valve if shortening temperature exceeds 400˚F
(204˚C).

2. Combination gas control valve which includes a built-in pressure regulator.

3. Air pressure switch to open the 24volt electrical circuit to the gas control valve, which turns

gas to the fryer OFF if a blower motor becomes inoperable.

4. Sensing Circuit within the spark ignitor module to turn gas OFF if a burner FLAME OUT

occurs.

5. A current sensor and air pressure switch, combined provide an air proof system for the

fryer.

6. A drain valve safety switch and a default to OFF circuit that will disable the fryer each time

the drain valve is opened.

Ultrafryer Systems are listed below:

2. PRE-INSTALLATION

2.1. GENERAL

Safe and satisfactory operation of a Model F-IRC-14 premix gas fryer depends on its proper
installation. Installation must conform to local codes or, in the absence of local codes, with the current
National Fuel Gas Code ANSI Z223.1/NFPA 54 or (latest edition). In Canada, gas installation shall be in
accordance with the current CSA B 149.1 and .2 installation codes and/or local codes. Each Model F­IRC-14” premix gas fryer should be installed as follows:

1. Placed beneath a properly designed exhaust hood.

2. Installed by a licensed electrician and plumber.

3. Connected to the type gas for which the unit was fabricated as shown on the rating plate.

4. Connected to the proper size pressure regulator installed in the gas supply line and adjusted

to the proper manifold pressure.

5. Connected to the main gas supply line with the proper size supply line.

6. Restrained by use of a restraining device to avoid splashing of hot liquid and to assure tension

cannot be placed on the flexible gas or electrical lines or fittings. CLEARANCES: The appliance
must be kept free and clear of all combustibles. The minimum clearance from combustible
and non-combustible construction is 6" (152 mm) from the sides, and 6" (152 mm)
from rear. The fryer may be installed on combustible floors.

NOTE:

Model F-IRC-14

Revision – Sept 2017 Page 9 of 38 Document # 30A290

2.2. STANDARDS

Installation must be planned in accordance with all applicable state and local codes, considering the
following standards:

1. The fryer and its individual shut-off valve must be disconnected from the gas supply piping

system during any pressure testing of that system at pressures in excess of 1⁄2 psig (3.45kPa).
In Canada, gas installation shall be in accordance with the current CSA B 149.1 and .2
installation codes and/or local codes.

2. The fryer must be isolated from the gas supply piping system by closing its individual manual

shut-off valve during any pressure testing of the gas supply piping system at pressures equal
to or less than 1⁄2 psig (3.45kPA).

3. When installed the fryer must be electrically grounded in accordance with local codes, or in

the absence of local codes, in accordance with the current National Electrical code
ANSI/NFPA 70 or latest edition. In Canada electrical installation must be in accordance with
the current CSA C22.1 Canadian Electrical Code and/or local codes.

4. Other applicable nationally recognized installation standards such as:
a. National Fuel Gas Code ANSI Z223.1/NFPA 54 or latest edition

American Gas Association.

b. NFPA Standards #54, #94 and #221 latest edition

National Fire Protection Association.

c. ANSI Z21.69/CSA-6.16 AND ANSI Z21.41/CSA 6.9

5. Exhaust vent hood, when installed must conform to the current NFPA 54-1 and Canadian

Standards or latest edition.

NOTE:

Local building codes will usually not permit a fryer with its open tank of hot oil to be installed
immediately next to an open flame of any type, whether a broiler or an open burner or range.
Check local codes before beginning installation.

2.3. AIR SUPPLY AND VENTILATION

The area around the appliance must be kept clear of any combustible or flammable products and
avoid any obstruction to the flow of ventilation air as well as for ease of maintenance and service.
NOTHING is to be stored in the interior of the fryer’s cabinet.

1. A means must be provided for any commercial, heavy duty-cooking appliance to exhaust

combustion wastes outside of the building. It is essential that a fryer be set under a powered
exhaust vent hood or that an exhaust fan be provided in the wall above the unit, as exhaust
temperatures are in the vicinity of 700˚F (371˚C).

NOTE:

Strong exhaust fans in a hood or in the overall air conditioning system can produce slight air
drafts in the room, which can interfere with burner performance and be hard to diagnose. Air
movement should be checked during installation and if burner problems persist, make-up air
openings or baffles may have to be provided in the room.

Model F-IRC-14

IMPROPER INSTALLATION, ADJUSTMENT, ALTERATION, SERVICE, OR MAINTENANCE CAN CAUSE

PROPERTY DAMAGE, INJURY, OR DEATH. READ THE INSTALLATION, OPERATING AND MAINTENANCE

INSTRUCTIONS THOROUGHLY BEFORE INSTALLING OR SERVICING THIS EQUIPMENT.

A Caster may not return exactly to the same position after being moved, which may require
re-leveling after each move.

CONNECT-IT Inc. ¾” (19mm), 1” (25mm) and 1 ¼” (32mm) flexible gas hose 4 feet long (1219mm)
with a quick disconnect coupling on one end is available from Ultrafryer Systems under PN 24322

(3/4” (19mm) hose), PN 24323 (1” (25mm) hose) and PN 24456 (1 ¼” (32mm) hose). These hoses are

equipped with a fusible link, which melts at 316 °F (183 °C) that will SHUT OFF the gas supply when
it melts. Reference Installation Instructions sheet provided with hose for additional information. A

44” (1119mm) long restraining device is also available under PN 24324. Install as Shown below

between the wall and fryer using existing mounted hardware or add hardware to the wall and fryer
making a secure connection at each end.

2. Exhaust temperature, in addition to the open tank of hot oil, make the storage of anything

on shelving over or behind the fryer unsafe.

3. Filters and drip troughs should be part of any industrial hood, but consult local codes before

constructing and installing any hood.

3. RECEIVING AND INSTALLING

3.1. UNPACKING

Check that the container is upright. Use an outward prying motion – DO NOT USE A HAMMER - to
remove the carton. Check the fryer for visible damage; if such damage has occurred do not refuse
shipment, but contact the carrier and file the appropriate freight claims.

3.2. INSTALLING

Roll the assembled fryer into the building, to its operating location.

WARNING:

3.3. LEVELING

1. When the fryer is placed in its operating location, check to be sure it is level. If not, loosen

the casters and insert the appropriate number of shim plates between leg and caster plates
then retighten the caster bolts.

2. If the floor is smooth and level, adjust to the high corner and measure with a spirit level. If

the floor is uneven or has a decided slope, level the unit with metal shims.

with local demand. External regulators are not required on this fryer, as that function is

Model F-IRC-14

Revision – Sept 2017 Page 12 of 38 Document # 30A290

performed by a combination gas control valve, however if the incoming pressure is in excess of
1⁄2 psi, a step-down regulator will be required.

3. Natural gas: Natural gas fryers require 7” (178mm) water column (W.C.) “inlet” pressure to the

fryer’s combination gas control valve for proper operation, when all gas units are operating

4. simultaneously. Propane gas fryers require 14" (356mm) water column (W.C.) “inlet” pressure

to the fryer’s combination gas control valve for proper operation, when all gas units are

5. operating simultaneously. This “inlet” pressure MUST be checked with a manometer PRIOR to

placing the fryer in operation.

WARNING:

IF THE “INLET” GAS PRESSURE AT THE FRYERS COMBINATION GAS CONTROL VALVE “EXCEEDS” 1/2 lb/in2

(.035 kg/cm2) OR APPROXIMATELY 11” (280mm) W.C., AN EXTERNAL REGULATOR MAY BE NEEDED TO
PREVENT DAMAGE TO THE COMBINATION GAS VALVE, AND VOIDING OF WARRANTY.

6. Combination gas control valve: The correct combination gas control valve and orifice is installed

at the factory for NATURAL and PROPANE units based on each Purchase Order. This valve

7. should be CHECKED/ADJUSTED by qualified service personnel using proper test equipment for

The gas valve is considered part of the Blower Premix 5.0 Power Burner and Gas Valve assembly. If the gas
valve fails and needs to be replaced, you must order a complete blower / gas valve assembly (burner). The
reason for this is every blower / gas valve assembly (burner) is set up at the factory to operate at the most
efficient level possible. This set up procedure can not be duplicated in the field.
