INSTALLATION

Pre-Installation Instructions
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 specifications. The installation and connections must comply with local codes, or in the absence of local codes, with CAN/CGA-B149 installation code or with the National Fuel Gas Code, ANSI Z 223.1/NFPA No. 54 – latest edition.
All burner adjustments and settings shall be made by a qualified gas technician.

A. The type of gas for which the unit is equipped is stamped on the data plate located behind the lower front panel. Connect a unit stamped “NAT” only to natural gas; connect a unit stamped “PRO” only to propane gas.
B. If it is a new installation, have gas authorities check meter size and piping to assure that the unit is supplied with sufficient amount of gas pressure required to operate the
unit.
C. If it is additional or replacement equipment, have gas authorities check the pressure to make certain that the existing meter and piping will supply fuel at the unit with not more than  1/2” water column pressure drop.
D. Obtain a pressure regulator to deliver gas at the pressure shown on the rating plate. This unit is supplied with a pressure regulator.
NOTE: When checking pressure be sure that all other equipment on the same gas line is on. A pressure regulator is supplied with GARLAND equipped. Set the regulator to deliver gas at the pressure shown on the rating plate. Installation must conform with the National Fuel Gas Code ANSI Z223.1-Latest Edition/NFPA No. 54-Latest Edition and/or local code to assure safe and efficient operation.
NOTE: In Canada, the installation shall be in accordance with CAN/CGA-B149.1 NATURAL GAS INSTALLATION CODE or CAN/CGA-B149.2 PROPANE GAS INSTALLATION CODE and local codes where applicable.
NOTE: The appliance and its individual shut-off (supplied by others) must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 PSI (3.45kPa).
The appliance must be isolated from the gas supply piping by closing its individual manual shut-off (supplied by others) 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: Adequate clearance must be provided for servicing and proper operation.
Legs Raise the front of the oven. Position the legs inside the front corners of the angle from the frame. Start each bolt, threading them into the weld nuts on the angle base frame.  Four (4) bolts and four (4) washers must be used to secure each leg in place. Tighten the bolts evenly and securely. Raise and block the rear of the oven and fasten the rear legs as above.

Assembly of Two-Section Oven
Before raising the upper section into its proper position, check at the rear center of the underside of the upper section (as per drawing). The rectangular flue opening should be open. If the flue opening is covered, remove the “Bottom Flue cover Patch” and discard.

Be sure that the top trim cap (stainless steel angle iron square frame) is not installed on the lower or middle ovens. Place 2 x 4’s on the top of the lower or middle ovens. Place 2  x 4’s on the top of the lower oven section – about 6” in from each side, running front to back. Raise the top section and position it on the 2 x 4’s so that the front, rear, and sides of the top section line up with the lower section. The internal upper flue will telescope over the internal lower flue.
The upper oven section bottom frame will telescope or capture the bottom unit. It is not necessary to bolt the section together.

Installation of Oven Vent

1. The most efficient system for ventilating this oven is a properly designed hood. This hood should extend 6 inches beyond the front and sides of the oven and the back unless the oven is against a fire resistive wall. The design of the hood should be such that it will not pull the heat too rapidly out of the oven through the flue.
   The flue deflector provided (Fig. 1) should be installed to prevent this situation from occurring. Set the flue deflector in place over the flanges of the internal flue. The sloped opening of the flue deflector will be to the front.
   Fasten the side flanges of the flue deflector by means of the sheet metal screws provided.

2. If the oven must be connected to a direct flue, this flue should rise 10 feet above the roof of the building in which the oven is installed, or 10 feet above any portion of a  building within a horizontal distance of 10 feet. The draft hood provided must be installed. In addition, it is necessary that barometric draft control (available from Garland)  be installed. (See Fig. 2) The draft hood should be positioned with its vertical bottom opening over the vertical flanges of the oven flue. The flanges of the draft hood should be to the sides and front. Fasten the draft hood to the oven by means of sheet metal screws through the holes on each side flange at the bottom of the draft hood.
   The barometric damper must be installed to conform with the applicable instructions packed with the barometric damper. The relief opening of the barometric damper should be located so that it is not obstructed by any part of the oven or adjacent constructions.
   The barometric damper should be installed as close to the draft hood as possible while conforming to code requirements.
   Under no circumstances should a flue pipe with less than a 6-inch diameter be installed between the oven and the chimney termination.
   If more than one appliance is connected to a single vent, the vent shall be sized in accordance with sound engineering principles.
   

Top Trim Installation
The front of the top trim is formed as a channel. Open the upper oven door. Hold the top trim with the rear raised and slide its lower flange into position in the oven opening between the right and the left front columns. Lower the top trim into position over the oven top. The top trim does not require that it be bolted or fastened into position.
Ovens with Optional Light Feature
Important: This appliance must be electrically grounded in accordance with local codes, or in the absence of local codes, the Canadian Electrical Code C22.1 or with the  National electrical code ANSI/NFPA No. 70 (latest edition whichever is applicable.
Warning – Electric Grounding Instructions
This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazards and must be plugged into a properly grounded three-prong receptacle.
Do not cut or remove the grounding prong from this plug.
A wiring diagram is attached to the back of the unit.
Gas Connection-Single & Multiple Ovens
Single Oven
Install the pressure regulator (supplied) with the outlet (arrowhead) connected to the tail pipe. The ¾” N.P.T. inlet of the pressure regulator must be considered in piping the gas supply. Each group of ovens should be supplied (by others) with an in-line manual shut-off valve.

Each stack of oven sections may be piped individually as described above. Each stack should be provided with its own manual gas shut-off valve as described. If the ovens are to be piped using all of the materials provided, refer to diagram “A”.
Multiple Ovens
If the ovens are to be stacked, they may be piped as shown in diagram “A”. Again, as stated above, a readily accessible gas shut-off valve of an approved type should be installed in the supply line.

Installation Of Oven Heat Deflectors, Cordierite/Steel Hearths & Inner Oven Linings
All models require that two-part oven heat deflectors (heavy gauge diamond plate) and two heat deflector pans (in the oven with cordierite deck material) or one heat deflector pan  (in the oven with steel deck), be installed above the oven burners to give even heat throughout the oven. Install the heat deflector pan(s) in the center of the oven deck frame. Install the heat deflectors on top of the heat deflector pans, with the rough side up.
Both deflectors should be brought together to make the center seam as tight as possible.
The corderite hearth assembly consists of two sections installed within deck spacers, as shown in Diagram “B”. Install the two (2) aluminized inner oven linings in the front and rear channels by first placing the rear of each in each rear channel. Then raise the front of each aluminized inner oven linings over and down into the front channels.

The steel hearth is designed as a one-piece welded assembly and will pass through the oven door opening. The rear of the steel hearth assembly rests on the heat deflectors inside the rear angle support. Centre the steel hearth assembly within the oven. Install the aluminized inner oven linings provided, as shown in Diagram “B”.

IMPORTANT: All gas burners and pilots need sufficient air to operate and large objects should not be placed in front of this appliance which would obstruct the air flow through the front.
Ventilation and Air Supply
Proper ventilation is highly important for good operation.
The ideal method of venting a gas deck oven is through the use of a properly designed canopy which should extend 6” beyond all sides of the appliance and 6’6” from the floor.
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. For proper air balance, contact your local H.V.A.C. contractor.
Installation of a Direct Flue
When the installation of a canopy-type exhaust hood is impossible, the oven may be direct vented. Before direct venting check your local codes on ventilation.
If the unit is to be connected directly to a direct flue, it is necessary that an 8” draft diverter be installed to insure proper ventilation. First, remove the canopy diverter (shown in  Diagram “A”), and replace it with a Garland- designed down draft diverter (P/N1056497 painted or 1056496 stainless steel). Connect directly to the Garland-designed down draft diverter with your stove pipe.

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 and workmanship, and they are not covered under the original equipment warranty.
Do Not Undersize The Vent Pipe! This can cause resistance to flow and impede good efficiency.

OPERATION

Once the equipment has been installed and tested by qualified professional personnel, the oven is ready for operation. If the pilot is not lit, proceed as follows:

1. Check the oven gas valve. It should be in the “OFF” position. If not, turn this valve to the “OFF” position.
2. Remove the lower front panel by turning the special self-retaining fasteners.
3. Ignition of the pilot is made by passing a lighted taper through the access hole in the front air shield, or by removing this shield while pressing in and holding the red reset button of the oven safety valve. This button is reached through the access hole in the center section of the side control panel. Release the red button after the pilot has been lit, approximately 45 seconds. If the pilot does not remain lit, repeat after waiting 5 minutes.
4. After the oven pilot is lit, replace the front air shield and lower front panel.

Burn Off – Deck Curing
Many of the parts used in the oven have a thin protective oil covering. This oil should be burned off before the oven is used for the production of food. The following burn-off procedure will also serve to “cure” the oven hearth. If the curing procedure is not followed, there is a potential for the deck material to crack.
Turn the oven thermostat dial back to the 300°F setting and run the oven at this temperature for at least an hour. Repeat at 400°F and 500°F. the total “curing” process is accomplished in a 3-hour period of time.

The oven may now be shut down by turning the gas control valve to the “OFF” position and turning the thermostat back to its lowest setting.
NOTE: You cannot turn the oven off just by turning the oven thermostat down. You must turn the gas valve to the “OFF” position.
It will not be necessary to extinguish the oven pilot unless the oven is to remain unused for a long period of time.
After the hearth is “cured”, the oven is ready for operation.

1. If the oven pilot has been extinguished, go through steps 1 through 4, as previously listed.
2. All models that have the cordierite hearths should be preheated for no less than one (1) hour. This will bring the oven interior to the desired temperature and will provide time for the hearth and the oven interior surfaces to absorb and store the heat required for optimum oven performance. All models that have steel hearths will require approximately 25 minutes to preheat.
3. After preheating, the oven is ready for use.
4. Distribute the load evenly on the deck. Space pans equally from each other and the side of the oven.
5. Planning will avoid unbalanced baking as a result of adding products after loading goods have started to bake.
6. Do not open the door unnecessarily. Repositioning of product is not required in most cases.
7. When using the G-2771 or the G-2772 General Purpose Oven for the same product, load the upper compartment first, then the lower compartment. It is normal for the upper compartment (in this specific model only) to be 30°F to 60°F lower in temperature than the lower chamber. When a product is done in the lower compartment,  remove the same. Check the upper compartment, allowing additional time if required.
8. Before loading, preheat the oven at least 25°F higher than the desired temperature for Strong bottoms and Light tops.
   When the loading of the oven is completed, turn the control down to the desired temperature. For products requiring Strong tops, turn the oven temperature control up to 25°F for the final 8 –  10 minutes of baking.

The following is intended only as a guide. Temperature and time requirements will be affected by specific recipes, varying methods of food preparation, quality of ingredients, and personal preferences, as well as numerous other factors. Your own techniques, coupled with the recommendations of this guide, will permit you to establish your own chart.

MAINTENANCE

We suggest maintenance and repairs to be performed by a GARLAND AUTHORIZED SERVICE AGENT. The listing provided with your oven is titled “Maintenance and Repair Centres”.
Stainless Steel
For routine cleaning, just wash with hot water and a detergent solution. Wash just a small area at a time or the water will evaporate leaving the chemicals behind and causing streaking.
Rinse the washed area with a clean sponge dipped in a sanitizing solution. Wash just a small area at a time or the water will evaporate leaving the chemicals behind causing
streaking.
Rinse the washed area with a clean sponge dipped in a sanitizing solution and wipe dry with a soft clean cloth before it can dry.
Use a paste (of water and a mild scouring powder) if you have to, but never rub against the grain. All stainless steel has been polished in one direction. Rub with the polish lines to preserve the original finish. Then thoroughly rinse as before.
To prevent fingerprints, there are several stainless steel polishes on the market that leave an oily or waxy film. Do not use on surfaces that will be in contact with food.
Stainless Steel may discolor if overheated. These stains can usually be removed by vigorous rubbing with a scouring powder paste.
Use only stainless steel, wood, or plastic tools, if necessary, to scrape off heavy deposits of grease and oil. Do not use ordinary steel scrapers or knives as particles of the iron may become embedded and rust. STEEL WOOL SHOULD NEVER BE USED.
Oven Interior
Standard aluminized steel interior surfaces. The oven linings, back linings, and top linings are formed with heavy gauge steel with aluminum fused into its surface. This provides
a reflectance of heat back to the food being prepared.
The aluminum virtually eliminates the possibility of rust formation.
To clean the aluminized interior, use concentrated detergent on a plastic pad to remove burned soil. DO NOT use steel wool, oven cleaners or abrasive powders. These will remove the aluminum. Rinse with warm water on a soft cloth.
Be sure to remove all traces of detergent. Any discoloration which may remain after the soil build-up has been removed will not affect the performance of the oven.

Cleaning of Oven Hearth
The oven hearth should be kept clean and free of carbon by using a long- handled, stiff wire brush or scraper to loosen burned-on carbon. Sweep the hearth clean with a soft brush. You may use a damp cloth to wipe the hearth, but DO NOT FLOOD THE HEARTH WITH WATER OR USE A VERY WET CLOTH! If excess water is used, the hearths may crack upon the next use.
