GAS FRYERS

All Imperial Mfg. Co. equipment is manufactured for use with the type of gas specified on the rating plate

and for installation in accordance with ANSI Z223.1/NFPA 54 (latest edition) of the National Fuel Gas Code, the
National Gas Installation Code, CSA/B149.1 or the Propane Installation code, CSA/B149.1, as applicable.

Instructions to be followed in case the user smells gas are to be posted in a prominent location in the kitchen area.
This information shall be obtained by contacting the local gas company or gas supplier.

IMPORTANT

Installing, Operating and Service Personnel:

Installation of the equipment should be performed by qualified, certified, licensed and/or authorized
personnel who are familiar with and experienced in state/local installation codes. Operation of the equipment should
be performed by qualified or authorized personnel who have read this manual and are familiar with the function of
the equipment. Service of the equipment should be performed by qualified personnel who are knowledgeable with
Imperial Ranges.

INSTALLATION INSTRUCTIONS:

DO NOT install the fryer next to any open flame section of a broiler, range or any other appliance. The
fryer should be placed in an area which is free from drafts and accessible for proper operation and servicing. The
area around the fryer must be kept clear of combustible materials.

CLEARANCE COMBUSTIBLE NON-COMBUSTIBLE

Sides 6” 0”
Rear 6” 0”
Floor 6” 6”

Installation on non-combustible floor only shall be with factory supplied legs or casters. Counter model
(IFST-25) shall have 4” legs and is to be installed on a non-combustible counter or stand.

It is also important not to obstruct the natural flow of combustion and ventilation air if the fryer is to
operate properly. Provide adequate clearance around air openings into the combustion chamber.

RATING PLATE:

Before making any connections to the fryer, check the rating plate to be sure the fryer specifications concur
with the type of gas to be supplied to the fryer. The rating plate is located on the inside of the door.

Information on this plate includes model and serial numbers. When communicating with the factory about
a unit or requesting special parts or information, this data is essential for proper identification. Other information on
this plate is the BTU/hr input of the burners, operating gas pressure in inches WC, and whether the unit is orificed
for natural or propane gas. Pilot lighting instructions are also located in the same area.

GAS PIPING:

The installation of the fryer must conform with local codes, or in the absence of local codes, with the
National Fuel Code, ANSI Z223.1/NFPA 54, the National Gas Installation Code, CSA B149.1, as applicable.

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 test pressures in excess of ½ Psig (3.45KPa).

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 test pressures equal to or less than 35
mbar (3.45 KPa). The fryer is provided with a ¾” NPT inlet.

Your local gas supplier should consult the Local Fuel Gas Code for proper sizing and installation of gas

piping. Generally, piping should be sized to provide a gas supply sufficient to meet the maximum demand of all gas
appliances on a line without undue loss of pressure at the outlet to the equipment. The total BTU requirements of
the equipment being served and the length of the piping from the meter to the appliances are major considerations in
the proper design of the gas supply system.

Sealants on pipe joints must be resistive to propane gas. Check for leaks at all connections with soap
solution. Do not use flame to check for leaks.

Imperial fryers are equipped with millivolt control system, it does not need an outside power source.

VENTILATION:

Proper ventilation is very important for the proper function of your fryer as well as to remove unwanted
vapors and products of combustion. To keep your warranty in force, a proper ventilation system must be employed.

LEVELING:

CAUTION

Burners shall not be “ON” when the vessel is empty. During testing, fill the vessel with liquid (oil or water) till above the

heat transfer tubes.

WARNINGS

Hot oil and hot surfaces can cause severe burns. Use caution when operating the fryer. Do not attempt to move

the fryer filled with hot oil or shortening. Do not go near the area directly above the flue when fryer is in

operation. Severe burns may be caused. Drain hot oil in metal containers, do not use plastic buckets or glass

containers.

After setting in position, level the fryer front to back and left to right. If it is not leveled, the fryer may not
function properly.

LIGHTING INSTRUCTIONS:

1. Set the thermostat and the gas cock dial on the combination gas valve to the “OFF” position.

2. Wait for five minutes

3. Turn gas cock dial on the combination gas valve to “PILOT” position.

4. Depress the gas cock dial and apply a lighted match or taper to the pilot.

5. Hold the gas cock dial depressed for about 30 seconds or until pilot stays lit before releasing.

6. If the pilot does not stay lit, repeat steps 4 and 5.

BURNERS/THERMOSTAT OPERATION:

1. After the pilot is lit, turn the gas cock dial to “ON” position.

2. Turn the thermostat dial to any temperature setting and observe the burners ignition. It should ignite within

four seconds.

FLEXIBLE COUPLINGS, CONNECTORS AND CASTERS:

If the unit is to be installed with flexible couplings and/or quick-disconnect fittings, the installer must use a
heavy duty AGA design-certified commercial flexible connector of at least ¾” NPT (with suitable strain reliefs).
The flexible connector must comply with the standard of Connectors for Movable Gas Appliances, ANSI Z21.69
and addendum Z21.69a (or latest edition) and a quick-disconnect device that complies with the standard for quick­disconnect devices for use with Gas Fuel should comply with ANSI Z21.41 and addendum Z721.41a (or latest
edition). If disconnection of the restraint is necessary, make sure to reconnect restraint after the appliance has been
returned to its originally installed position. Domestic gas or water connectors are not suitable!

Restraining device may be attached to the back frame/panel of the unit.

If the unit is to be installed with the optional casters, a flexible connector must be used and the same ANSI
standards apply. Locking front casters are provided to limit the movement of the appliance without depending on
the connector or associated piping. A suitable strain relief must be installed with the flexible connector.

All connections must be sealed with a joint compound suitable for LP gas and all connections must be
tested with a soapy water solution before lighting pilots.
