INSTALLATION

NOTICE

Installation must conform with local codes, or in the absence of local codes, with the National Fuel
Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane
Installation Code, CAN/CGA-B149.2, as applicable.

NOTICE

These installation procedures must be followed by qualified personnel or warranty will be void.

Local codes regarding installation vary greatly from one area to another. The National Fire Protection
Association, Inc. states in its NFPA 96 latest edition that local codes are the “authority having
jurisdiction” when it comes to installation requirements for equipment.

INSTALLATION

Step 1: Unpack

IMMEDIATELY INSPECT FOR SHIPPING DAMAGE

All containers should be examined for damage before and during unloading. The freight carrier has
assumed responsibility for safe transit and delivery. If damaged equipment is received, either
apparent or concealed, a claim must be made with the delivering carrier.

Apparent damage or loss must be noted on the freight bill at the time of delivery. The freight bill must
then be signed by the carrier representative (Driver). If the bill is not signed, the carrier may refuse
the claim. The carrier can supply the necessary forms.

A request for inspection must be made to the carrier within 15 days if there is concealed damage or
loss that is not apparent until after the equipment is uncrated. The carrier should arrange an
inspection. Be certain to hold all contents plus all packing material.

1. Uncrate carefully. Report any hidden damage to the freight carrier IMMEDIATELY.

2. Do not remove any tags or labels until unit is installed and working properly.

SECTIONAL DEEP FRYER INSTALLATION

Step 3: Install the Legs (or Casters) and Restraint

A set of legs or casters is packed with the fryer. A threaded pad is fastened to the base frame at each corner
(see illustration on page 8). Each leg or caster has a similar mating thread. When casters have been
ordered, the casters are provided with a Zerk fitting for proper lubrication when required.

1. Raise fryer sufficiently to allow legs or casters to be screwed into the pads. For safety, “shore up” and
support the fryer with an adequate blocking arrangement strong enough to support the load.

2. Screw the four legs or casters to the pads on the bottom of the fryer. When casters have been ordered,
the casters having a locking-brake should be attached under the front of the fryer.

3. Lower the fryer gently. Never drop or allow the fryer to fall.

4. Use a level to make sure that the fryer is level. Each caster, or the tubular-end of each leg, can be
screwed in or out to lower or raise each corner of the fryer. For fryers having casters, tighten the lock
nuts after the unit has been leveled.

5. Attach restraints as required by local codes.

NOTICE

Unit must be level to assure maximum performance. Improper leveling may void warranty.

INSTALLATION

NOTICE

Adequate restraining means must be attached to rear of appliance when installed. Installation must
conform to local codes as applicable.

! WARNING

If disconnection of the restraint is necessary to move the appliance for cleaning, etc., reconnect it
when the appliance is moved to its original installed position.

! WARNING

For an appliance equipped with casters, 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, CAN1-6.9. Adequate means must be provided to limit the movement
of the appliance without depending on the connector and the quick-disconnect device or its
associated piping to limit the appliance movement.

! WARNING

All fryers must be restrained to prevent tipping in order to avoid the splashing of hot liquid. The means
of restraint may be the manner of installation, such as connection to a battery of appliances or
installing the fryer in an alcove, or by separate means, such as adequate ties.

INSTALLATION SECTIONAL DEEP FRYER

Step 4: Assembly of Fryer as Part of a Battery

If the fryer is to be assembled with other units as part of a battery, do the following:

1. Position the center range of the battery and carefully level that unit. Use a long spirit level four ways;
across front top rail and the rear collar plate, and along each edge.

2. Remove all front valve panels. Mark them so that they can be returned to their respective unit.

3. Bring up adjacent unit and level it using the same method and by using the center unit as reference.
Match front rails and rear collar plates. When a battery is set on a masonry base and legs are not used,
shims may be used. Special attention should be given to Fry Top ranges to allow proper drainage on
griddles.

4. Where spreader plates are installed, refer to Sectional Battery Component Assembly Instructions

INSTALLATION

supplied with each unit.

5. Connect and test the gas supply as described in Step 5, then re-install the valve panels.

Step 5: Gas Connection

The fryer has a 1-1/4" gas supply manifold located inside the top front edge and an optional 1" a rear gas
connection (see illustrations on pages 8, 35, and 37). Depending on the customer’s specification when the
unit was purchased, the ends of the gas supply manifold may both be open (for connection to adjacent units
on both sides), one may be open (for connection to one adjacent unit), or neither may be open (for a
freestanding fryer). The optional rear gas connection may be present for use by a freestanding fryer, or as a
supply connection for a battery.

The serial plate (located inside the front door of the fryer) indicates the type of gas the unit is equipped to
burn (natural gas or propane). The fryer should be connected ONLY to the type of gas for which it is
equipped.

All Blodgett Range equipment is adjusted at the factory; however, pilot height should be checked at
installation and adjusted, if necessary (see page 24).

For orifice sizes and pressure regulator settings, see the chart on page 6. If the fryer is being installed at over
2,000 feet altitude and that information was not specified when ordered, contact the appropriate Authorized
Service Agent or the factory service department. Failure to install with proper orifice sizing will result in poor
performance and may void the warranty.

If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in
accordance with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI

Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code, CAN/CGA­B149.2, as applicable.

An adequate gas supply is imperative. Undersized or low-pressure lines will restrict the volume of gas
necessary for satisfactory performance. A combination gas valve and pressure regulator, which is provided
with each unit, is set to maintain a 4" W.C. manifold pressure for natural gas or 10.0" W.C. manifold pressure
for propane gas. However, to maintain these conditions the pressure on the supply line, when all units are
operating simultaneously, should not drop below 7" W.C. for natural gas or 11" W.C. for propane gas.
Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems and affect burner
operating characteristics. A 1/8" tap to measure the manifold pressure is located on the burner manifold (see
illustrations on pages 35 and 37).

Purge the supply line to clean out dust, dirt, or other foreign matter before

It is recommended that an individual manual shutoff valve be installed in the gas supply line to the unit.

connecting the line to the unit.

Use pipe joint compound that is suitable for use with both natural and LP gas on all threaded connections.

PAGE 10 OPERATOR’S MANUAL 1184959

SECTIONAL DEEP FRYER INSTALLATION

! CAUTION

ALL PIPE JOINTS AND CONNECTIONS MUST BE TESTED THOROUGHLY FOR GAS LEAKS.
USE ONLY SOAPY WATER FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO
CHECK FOR GAS LEAKS. ALL CONNECTIONS MUST BE CHECKED FOR LEAKS AFTER THE
UNIT HAS BEEN PUT INTO OPERATION. TEST PRESSURE SHOULD NOT EXCEED 14" W.C.

! CAUTION

THIS APPLIANCE AND ITS INDIVIDUAL COMBINATION GAS VALVE MUST BE DISCONNECTED
FROM THE GAS SUPPLY PIPING SYSTEM DURING ANY PRESSURE TESTING OF THAT
SYSTEM AT TEST PRESSURES IN EXCESS OF 1/2 PSIG (3.45 kPa).

The appliance must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or
less than 1/2 psi (3.45 kPa).

NOTE: Although the fryer is equipped with an internal pressure regulator, other sectional units in a battery
may require an external pressure regulator. This pressure regulator must (1) be certified by a recognized
testing agency, (2) be acceptable for total pilot load application, (3) have a maximum regulation capacity for
the total connected load, and (4) have a pressure adjustment range to allow adjustment to the manifold
pressure on the appliance rating plate. Unless the manifold pressure of all connected appliances is the
same, a separate regulator must be supplied for each unit(s) to indicate unit or units having differing manifold
pressures.

INSTALLATION

If the fryer is to be connected to adjacent units in a battery, do the following:

1. Connect the units together by mating the supply-manifold unions. Just HAND TIGHTEN until all units
have been connected to each other.

2. Starting at the center and working toward the ends of the battery, tighten each union gradually, going
from one to another, until all are finally tight. A special thin wrench, which fits the union nut, is provided
with each battery, or a chain wrench can be used.

3. Connect the gas supply at right, left, or both ends. When a spreader plate with a “Tee” connection is
inserted in a battery, the gas supply may be connected at this point. Units with rear connections may
also be used in this respect. If five or more units are connected in one battery, more than one supply line
should be used. Each supply line should have a readily accessible, approved hand shutoff valve

If the optional rear gas connection is to be used, connect the gas supply directly to the 1" male NPT
connector located near the lower right rear corner of the fryer (see illustration on page 8). When tightening
the supply pipe, be sure to hold the mating connector extending from the unit securely with a wrench. This
will prevent any damage or distortion to the internal piping and controls of the unit.

For all installations, proceed as follows:

1. Check that all unused gas connections are capped.

2. Turn off all burner valves.

3. Turn on gas supply and immediately check all connections for leaks. USE SOAPY WATER ONLY FOR
TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO CHECK FOR GAS LEAKS.

4. When the entire gas system has been checked, turn off gas supply during the rest of the installation.

5. After connecting the gas supply, check that the fryer is level. Use a long spirit level four ways; across the
front and rear of the frypot, and along each edge.

OPERATOR’S MANUAL 1184959 PAGE 11

INSTALLATION SECTIONAL DEEP FRYER

Step 6: Check Clearances and Ventilation

Select a firm, level location for your fryer. Leave clearance, whenever possible, so that access from the rear
is possible to permit cleaning. If the unit is to be set on non-combustible flooring, such as a concrete slab, 3
inches minimum toe room must be provided to prevent restriction of the air opening in the bottom of the unit.

! WARNING

There must be adequate clearance between fryer(s) and construction. Clearance must also be
provided in front for servicing and for operation.

Minimum Clearances:

From Combustible Construction From Non-Combustible Construction

INSTALLATION

ALL DEEP FRYERS SHALL BE INSTALLED WITH AT LEAST A 16 INCH SPACE BETWEEN THE
FRYER AND SURFACE FLAMES FROM ADJACENT EQUIPMENT.

No additional side and rear clearance is required for service as the fryer is serviceable from the front.

Sides 6" 0"
Rear 6" 0"

! WARNING

Improper ventilation can result in personal injury or death. Ventilation that fails to properly remove flue
products can cause headaches, drowsiness, nausea, or could result in death.

All units must be installed in such a manner that the flow of combustion and ventilation air is not
obstructed. Provisions for adequate air supply must also be provided. Do NOT obstruct the bottom
front of the unit, as combustion air enters through this area. Be sure to inspect and clean the
ventilation system according to the ventilation equipment manufacturer’s instructions.

NOTICE

Proper ventilation is the owner’s responsibility. Any problem due to improper ventilation will not be
covered by the warranty.

Due to the variety of problems that can be caused by outside weather conditions, venting by canopies or wall
fans is preferred over any type of direct venting. It is recommended that a canopy extend 6" past the
appliance and the bottom edge be located 6'6" from the floor. Filters should be installed at an angle of 45° or
more from the horizontal. This position prevents dripping of grease and facilitates collecting the run-off
grease in a drip pan, unusually installed with a filter. A strong exhaust fan tends to create a vacuum in the
room and may interfere with burner performance or may extinguish pilot flames. Fresh air openings
approximately equal to the fan area will relieve such a vacuum. In case of unsatisfactory performance on
any appliance, check the appliance with the exhaust fan in the “OFF” position. Do this only long enough to
check equipment performance, then turn hood back on and let it run to remove any exhaust that may have
accumulated during the test.

The exhaust fan should be installed at least 2 feet above the vent opening at the top of the fryer.

This unit is not intended to be connected directly to an outside flue.
