commercial applications only. Garland / U.S. Range will not

provide service, warranty, maintenance or support of any

kind other than in commercial applications.

INSTALLATION

The importance of proper installation of commercial

gas cooking equipment cannot be overstressed. Proper

performance of the equipment is dependent, in great part,

on the compliance of the installation with the manufacturer’s

specications. In addition compliance with the National

Fuel Gas code ANSI Z 223.1-1988/NFPA and/or Local Code is

required to assure safe and ecient operation.

In Canada, the installation and connection must comply with

CAN/CGA – B149 Installation codes and local codes where

applicable.

All burner adjustments and setting shall be made by a

qualied gas technician.

Delivery and Inspection

Upon delivery of your GARLAND Gas AIR DECK, inspect

the carton for external damage. Uncrate oven and check

for concealed damage. Any evidence of damage should be

noted on the delivery receipt which must be signed by the

driver.

Location of the Oven

Appliances shall be installed in a location in which the

facilities for ventilation permit satisfactory combustion of gas

and proper venting. Appliances shall be located so as not to

interfere with proper circulation of air within the conned

space. When buildings are so tight that normal inltration

does not provide the necessary air, outside air shall be

introduced.

Clearances

Unit must be installed with no less than six inches (6”,

152mm) clearance from combustible construction at both

sides and rear.

Ventilation

Local codes and conditions vary greatly from one area

to another and must be complied with, following are

the minimum requirements for good ventilation. Please

remember these are general recommendations or

guidelines, you may have a special conditioner problem that

will require the services of a ventilation engineer or specialist.

Proper ventilation is the oven owner’s responsibility.

Improper ventilation can inhibit oven performance.

Part # 1382670 (12/07) Page 7

INSTALLATION Continued

Canopy Method

The ideal method of venting a gas oven is through the use of

a properly designed canopy which should extend six inches

beyond all sides of the appliance and six feet six inches

from the oor. A strong exhaust fan will create a vacuum

in the room, for an exhaust system vent to work properly,

replacement air must enter the room in which the vent is

located. The amount of air which enters must equal the

amount exhausted.

Direct Connection

An unrestricted vent pipe that provides exit air at the oven

of a minimum of 55 C.F.M. per oven must be provided for the

vent pipe at the top of the oven. The vent pipe should be a

minimum of 6” (152mm) in diameter. A direct connect kit can

be obtained through your dealer.

Do not Undersize Vent Pipe. This can cause resistance to ow

and impede good venting. If a horizontal run must be used

it should rise no less than 1/4” for each linear foot or run. The

ue should rise two feet to three feet above the roof line or

two feet to three feet above any portion of a building within

a horizontal distance of ten feet.

Termination Less than 10 feet (3 meters) from ridge

Direct Connection Instructions

The G56P-T/B (or double deck), may be direct vented to the

outside. In order to accomplish direct venting and maintain

proper oven operation, it is necessary to install a Direct

Venting Kit part #CK4529. This kit consists of a Heat Collector

(Part #1190100). The Heat Collector Box is mounted over the

ue at the rear of the oven and Draft Diverter is attached to

the top of the Heat collector as shown on next page.

The Heat Collector must be positioned over the rear ue and

as far forward as possible on top of oven. It is necessary to

mark and drill mounting holes on oven top to fasten Heat

Collector securely in place.

An unrestricted vent pipe that provides exit air at the oven

of a minimum of 55 C.F.M. per oven must be provided for the

vent pipe at the top of the oven. The vent pipe should be a

Gas Connections

The 1” NPT inlet of the rear must be considered in piping

the gas supply for double deck units. Undersized gas supply

line(s) may restrict the gas supply and aect performance.

If other gas appliances are supplied by the same supply

line, the supply line must be sized to carry the combined

volume without causing more than 1/2” pressure drop at the

manifold of each appliance on the line at full rate.

Part # 1382670 (12/07)Page 8

The appliance and its individual shuto 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 (3.45 KP2).

The appliance must be isolated from the gas supply piping

system by closing its individual manual shuto valve during

any pressure testing of the gas supply piping system at test

pressures equal to or less then

1/2 PSIG (3.45 KP2).

NOTE: During installation there will be air in the gas line. This

air will have to be bled o before ignition can be established.

The electrical ignition system has a four second lock-out as a

safety device.

Electrical Connections

A 15 AMP service must be provided for each oven. For 115

Volt usage a cord and plug is provided but connection to

the electrical service must comply with local codes or in

the absence of local codes with the National electrical code

ANSI/NFPA No. 70-1987 (or latest edition).

Each oven is electrically equipped with a cord set with a

three prong plug which ts all standard 115 Volt three prong

grounded receptacle. A wiring diagram is attached to the

rear of the unit.

POWER FAILURE: In the event of a power failure, no

attempt should be made to operate this oven. This unit is

gas operated but has electrical features, motors, controls

and burner systems.

Electrical Grounding Instructions

WARNING: All ovens, when installed, must be electrically

grounded in accordance with local codes, or in the absence

of local codes with the Nation Electrical code ANSI/NFPA 70-

1987 (or latest edition).

This appliance is equipped with a three prong (grounding)

plug for your protection against shock hazard and should be

plugged directly into a properly grounded three pronged

receptacle. Do not cut or remove the grounding prong

from this plug.

INSTALLATION Continued

Unit Assembly

1. Before assembly and connection check gas supply and

electrical service. It is recommended that a separate

electrical circuit be provided for the Air Deck. A single

unit will require 15 AMPS and a double will require a

20 AMP circuit.

2. Gas conditions for this unit are listed on the rating

plate, located just forward of the Louvered Panel of the

Power Module. If this is a new installation, have the gas

authorities check meter size and piping to assure that

existing meter and piping will supply fuel at the oven

with 3.5” W/C (for Natural Gas) or 10.0” W/C (for L.P. Gas)

and not more than 1/2” water column pressure drop.

NOTE: When checking pressure, be sure that all other

equipment on the same gas line is on. A gas pressure

regulator is built into the combination control valve and no

adjustment is needed.

Leg Installation – All Models

1. Oven is crated and shipped on its base. When uncrating,

the bottom of unit is exposed to facilitate leg installation.

Position the legs inside front and rear corners from frame.

Start each bolt, threading them into the weld nuts on

the base frame. Four (4) bolts with washers must be used

to secure each leg in place. Tighten the bolts evenly and

securely. The legs are interchangeable front to back, for

models “B” – longer legs for left side – shorter legs for

mounting to Power Module section: See line drawing.

Assembly of Double Unit

1. Install legs on bottom unit. Then place in position desired.

2. Place 2 x 4’s on top of the lower section about six inches

from each side, running front to rear.

3. Raise the top section and position it on the 2 x 4’s so that

the front, rear and sides of top section with the lower

oven section. Carefully remove the 2 x 4’s lowering the

CONCEPT OF AIR IMPINGEMENT COOKING

The “AIR DECK” Oven produced by GARLAND COMMERCIAL

INDUSTRIES INC., utilizes a revolutionary cooking concept,

called “AIR IMPINGEMENT”. It provides exceptional baked

food product quality in far less time than conventional

devices on the market. The “AIR IMPINGEMENT” system

directs a high velocity stream of heated air at the food

product being baked.

This blast eect penetrates the boundary layer of air

encircling the product and heats the food more eciently,

because the air concentrates heat on the food product.

Greater heat transfer rates, results in products baking two to

four times faster than conventional means, are possible with

“AIR IMPINGEMENT”.

The “AIR IMPINGEMENT” process develops the high velocity

air stream with a specially designed fan that draws super-

heated air from a heat source (either gas or electric). This

air is directed through a plenum chamber to patented “JET

PLATES” which have hundreds of focused jet ports that

“impinge” the heated air onto the food product surface. The

heated air is re-cycled to the heat source after striking the

food product, thus reducing energy consumption.

The “AIR IMPINGEMENT” process is tolerant enough for

sensitive food products and eects proper crisping and even

browning of such products as they pass through the oven,

because air is the medium which heats the food product. The

adjustable air controls for top and bottom jet plates allow

further enhancement of cooking.

OPERATION

Once the equipment has been installed and tested by

qualied professional personnel, the oven is ready for

operation.

Many of the parts used in the oven have a thin protective

oil covering. The oil should be burned o before the oven is

used for the production of food products. It is normal for the

unit to smoke while burning o excess oil. Washing the deck

of the oven with a damp clean cloth and mild soap solution

will remove some of the protective oil coating.

To start the oven, switch the power to on. Set oven

temperature dial to 400 degrees and let oven heat and

operate at this temperature for at least one hour.

The “Air Deck” utilizes an automatic ignition and pilot

ame sensing system. During normal operation, the power

burner will cycle on and o as necessary to maintain oven

temperature. There is a short “time delay” built into the

circuitry, and you should not be alarmed when the oven

“calls for heat” and the power burner does not operate

immediately.

You will nd that cooking with the “Air Deck” oven will be

much faster than the standard Bake/Roast and Pizza Ovens.

You will have to experiment with your recipes to become

accustomed to this new method. For example the warm-

up time is shorter than standard ovens. The oven can be

warmed and ready for use in as little as twenty (20) minutes.

A large pizza can be ready to serve in as little as ve (5)

minutes. These are “ideal conditions” times and will vary with

ventilation and use.

Heat control vent shutters (2), are located on the right side of

the oven cavity. These shutters must be adjusted to provide

the air ow top and bottom that you desire for your cooking

needs. Adjusting these shutters will provide you with many

cooking variations.

If unit fails to operate, it is recommended that only qualied

service personnel perform the repairs on this unit. A

troubleshooting chart is provided in this manual to assist

qualied service personnel in repair of the unit. However,

before you call a service technician you may want to make a

few simple checks. Make sure electricity and gas are available

to the oven prior to calling a Service Technician.

CAUTION: Disconnect power supply before attempting to

clean or service.

NOTE: Each oven has been factory tested and adjusted

prior to shipment. It may be necessary to further adjust

the oven as part of a proper installation. Such adjustments

are the responsibility of the installer. Adjustments are not

considered defects in material or workmanship, and they are

not covered under the original equipment warranty.

Oven Door

The “AIR DECK” oven door has adjustability as a design

feature. Although it is factory set, the tension can be adjusted

to suit the operator’s preference. In addition, after a long

period of hard use, the tension can be readjusted as required.

To adjust door tension it is necessary to remove left and

right front corners of unit by the two sheet metal screws.

This exposes the door hinge and spring assembly. The spring

hook passed through a bracket. A 1/4” x 20 nut is on the

spring hook forward of the bracket. If it is available, use a

7/16” deep socket and ratchet to turn the nut clockwise to

increase spring tension or counter-clockwise to relieve spring

tension. Make sure to adjust both sides equally.

The oven door is properly adjusted if the door remains fully

open and if the spring tension carries the door to the full

closed position from the half-closed position. Replace the

corner and fasten with screws.

Burner ame Adjustment

The “AIR DECK” utilizes a power burner assembly as a heat

source. To ensure peak eciency, a proper air-fuel mixture is

necessary. There is an inspection port (window) on the power

burner. There is an air shutter located on the blower motor

that should be adjusted to provide a good blue ame with

no yellow tips.

Below is a drawing illustrating the proper way to check the

burner blower air shutter adjustment.

Operation

First Stage – Trial for Pilot Ignition

On every call for heat (system start), the S86 performs an

internal safe-start check shows that a ame-simulating

condition is present.

During a normal start, the S86 opens the rst operator in

the gas control. This allows gas to ow to the pilot burner.

Simultaneously, the electronic spark generator in the S86

produces a 30,000 volt spark pulse output. This voltage

produces a spark at the pilot burner ignitor/sensor rod,

igniting the gas owing around the electrode. If the pilot

ame is not detected during the trial for pilot ignition, the

S86A and B will continue trying for pilot ignition until a ame

is established. The S86C and D contain a safety lockout timer

to limit the trial for pilot ignition period.

Second Stage – Main Burner Operation

When the pilot ame is established, a ame rectication

circuit is completed to the burner ground. The S86 ame

sending circuit detects the ame current and shuts the

spark generator o. At the same time the second operator

(main) is opened in the gas control, allowing fast ow to

the main burner. The pilot ame ignites the main burner

conventionally. On the S86C and D the ame current also

holds the safety lockout timer in the reset, or normal,

operating condition.

Safety Lockout Time (S & SD Only)

The safety lockout timer circuit starts timing the moment

the trial for pilot ignition starts. When the timing period runs

out, the trial for ignition ends, and the control module goes

into lockout. Before another attempt to start can be made

the S86 must be reset. Reset by adjusting the thermostat or

controller below room temperature, or to its “OFF” position.

An alternate method is to shut the system power “OFF”. If

normal ignition does not occur, use the trouble shooting

table to determine the problem.

Service

Preliminary Check

The following visual checks should be made before trouble

shooting and after installation of maintenance.

1. Check power to appliance and S86

2. Manual shuto cocks in gas line to appliance must be

open.

3. Make certain all wiring connections are clean and tight.

4. S86C & D module must not be in safety lockout. First de-

energize the system and wait at least one (1) minute. This

resets the module allowing a return to start condition.

Then energize the system.

5. Review the S86 system normal sequence of operation.

S Checkout And Trouble Shooting

NOTE: On servicing S86A, B, C and D models.

The S86E, F, G and H models can be used to directly replace

S86A, B, C and D models (E replaces A model, F replaces B, G

replaces C model and H replaces D model) and the S86B and D

can be used to replace S86F and H, respectively. However, the

S86A and C cannot be used to replace the S86E and G module

on IPI systems that use VR8520 gas controls. VR8440 or VR8520

valves will not function properly with the S86A or C.

Check Grounding

A common ground is required for the pilot burner, the

ignitor-sensor, the GND terminal of the S86, and the main

burner. The main burner generally serves as the common

ground. If the ground is poor or erratic, safety shutdowns

may occur occasionally even though operation is normal at

the time of the checkout. Therefore, if nuisance shutdowns

have been reported, be sure to check the grounding.

Part # 1382670 (12/07)Page 14

INTERMITTENT PILOT INSTRUCTIONS Continued

Note: If the ground circuit path is incomplete the S86C, D, G

and H system control will allow one trial-for-ignition before

going into safety lockout.

Electrical grounding connections at the pilot burner,

ignitor/sensor and S86 must be clean and tight. If lead wire

is damaged or deteriorated, use only No. 14 of 18 gauge,

moisture-resistant, thermoplastic insulated wire with

105C. (221 F) minimum rating as replacement. Excessive

temperature at the ceramic ame rod insulator can also

permit electrical leakage to ground. Examine the ame rod

and mounting bracket, and correct if bent out of position.

Replace Q345, Q346 Q348 or ignitor/sensor if insulator is

cracked.

Check Spark Ignition Circuit

The electronic module and step-up transformer in the S86

provides spark ignition at 15,000 Volts (open circuit). This

circuit can be checked at the S86 module as follows:

1. Turn o the manual gas cock to prevent the ow of gas.

2. Disconnect the ignition cable at the S86 stud terminal to

isolate the circuit from the pilot burner/ignitor/sensor,

and prepare a short jumper lead using heavily insulated

wire, such as ignition cable.

3. Energize the S86, touch one end of the jumper rmly to

the S86 ground terminal (GND). Do not disconnect the

existing ground lead. Move the free end slowly toward

the stud terminal to establish a spark and then pull the

lead wire slowly away from the stud. Note the length of

the gap at which arcing stops.

CAUTION: Do not touch either stripped end of jumper or

stud terminal. This is a very high voltage circuit and electrical

shock can result. Perform the test immediately upon

energizing the system – before the S86C,D,G goes into safety

lockout and interrupts the spark circuit.

4. An arc length of 1/8” (3.2 mm) or more indicates

satisfactory voltage output. Replace the S86 if not arc can

be established or the maximum gap is less then 1/8” (3.2

mm), and the fuse and power to the S86 input terminal

was okay.

Control Module Flame Sensor Circuit

The control module provides AC power to the ignitor/sensor

which the pilot burner ame recties to direct current. If the

ame signal back to the control module is not at least 1.5 μA

DC, the system will lockout. The output of the ame sensing

circuit cannot be checked directly, so check the ame

sensing circuit indirectly by checking the ame sensing

current from the ignitor/sensor to the control module as

follows.

1. Connect a meter (DC micrometer scale) in series with

the ame signal ground wire as shown below. Use the

Honeywell W136A Test Meter, or equivalent. Disconnect

the ground wire at the control module.

Connect the red (positive) lead of the meter to the free

end of the ground wire. Connect the black (negative)

meter lead to the quick-connect ground terminal on the

control module.

2. Restart the system and read the meter. The ame sensor

current must be at least 1.5μA, and the reading must be

steady. If the reading is below the value designated or the

reading is unsteady, check the pilot ame and electrical

connections as described above. Also, replace the ignitor/

sensor if the ceramic insulator is cracked.

MAINTENANCE AND CLEANING

Oven Exterior

Stainless Steel Surface

Stainless Steel surfaces can often be cleaned adequately

using a mild soap and warm water solution on a sponge or

soft cloth. Dry Thoroughly.

Stubborn stains or heat tint may require the use of a

commercial type cleaner, such as Penny-Brite or Copper-

Brite, rubbed in with a dry cloth or Stainless Steel pad. Always

rub in the direction of the polished lines. Rinse thoroughly

with fresh water and wipe dry.

Oven Interior

Aluminied Steel Surfaces

Aluminied Steel Surfaces should be cleaned with a damp soft

cloth and mild household detergent.

The oven deck and bottoms (Jet Plates) are removable. The

deck should be kept as clean as possible. Heavy spills and

carbon deposits, that are not easily removed with a soap and

water solution, should be scraped loose and removed.

Periodic removal of the deck and “Jet Plates” is strongly

recommended. This will enable you to remove any build-up

of deposits on the “Jet Plates”, and access the oven bottoms.

Particles may drop through the openings in the “Jet Plates”.

The entire oven bottom should be cleaned at least once a

year and more often under heavy usage conditions.

NOTE: Top “Jet Plates” are not removable.

WARNING: Failure to clean oven perforated deck surface and

“Jet Plate” will degrade baking performance

CAUTION: disconnect power supply before attempting

cleaning or servicing.

Bottom Jet Plate Installation

After periodic jet plate cleaning, they should be reinstalled

in the following manner. Plate marked “R or “RHT” should be

placed into unit on right hand side.

Note: The short sided

end of the jet plate shown

should be installed in the center

of the unit with the short end down

(toward bottom of unit)

The jet plate marked “L” or “LHT” should be placed on the left

side in the same manner as right plate (see note).

Intérieur Du Four

Les Surfaces En Métal Aluminé

Les surfaces en Métal Aluminé devraient être nettoyées avec

un linge humide et un détersif domestique doux

Les plaques (Jet Plates) et pont du four sont amovibles. Le

pont devrait être gardé propre autant que possible. Des

débordements épais et des dépôts charbonneux qui ne

peuvent être facilement enlevés avec du savon et de l’eau

devraient être grattés et enlevés.

L’enlèvement périodique du pont et des plaques « Jet Plates

» est vigoureusement recommandé. Ceci vous permettra

d’enlever toute accumulation de dépôts sur les plaques «

Jet Plates » et accéder aux fonds du four. Des gouttelettes

peuvent dégoutter par les ouvertures dans les plaques. Le

fond du four en entier devrait être nettoyé au moins une fois

par année et plus souvent si le four est utilisé abondamment.

NOTE : Les plaques supérieures ne sont pas démontables.

AVERTISSEMENT : si la surface perforée du pont ainsi que les

plaques « Jet Plates » ne sont pas nettoyées, la performance

de cuisson sera réduite.

PRUDENCE : débrancher l’alimentation électrique avant de

nettoyer ou de réparer.

Installation Des Plaques (Jet Plates)

Après un nettoyage pèrioduque, les plaques devarient être

réinstallées de la manière suivante: La plaque identi ée « R

» ou « RHT » devrait être placée dans l’appareil, sur le côté

droit.

NOTE: Le côté étroit

de la plaque illustrée

doit être installé au centre

de l'appareil et vers le bas

(vers la base le l'appareil).

La plaque identi ée « L » ou « LHT » devrait être placée sur le
