Installation, Operation and Care
General
Forno ranges are manufactured with quality workmanship and materials. Proper installation, usage, and maintenance will result in many years of satisfactory performance. It is recommended to read this entire manual and follow all instructions carefully.
WARNING: This appliance is equipped for Natural Gas. For conversion to LP (Propane) gas, refer to the attached gas conversion instruction manual. Necessary orifices for LP conversion are provided. Consult page 3 for the orifice size list.
Installation
Uncrating
The range was inspected before factory shipment. The transportation company is responsible for safe delivery upon acceptance. Immediately after unpacking, check for shipping damage. If damage is found, save packaging materials and contact the carrier within 15 days of delivery.
Uncrate the unit carefully and place it in a work-accessible area, as close to its final installed position as possible. Remove all shipping wire and wood blocking.
Before installation, verify the type of gas supply (natural or propane) matches the specifications on the rating plate, typically located inside the lower kick panel. If the supply and equipment requirements do not match, do not proceed with installation and contact your dealer or company immediately.
Location
The appliance must be installed under a ventilation hood. The equipment area must be kept free of combustible substances.
Minimum clearances from combustible construction are:
- Sides: 12 inches (304 mm)
- Rear: 10 inches (253 mm)
Clearances from non-combustible construction are:
- Sides: 0 inches
- Rear: 6 inches (152 mm)
The installation location must allow adequate clearances for servicing and proper operation. A minimum front clearance of 40 inches (1016 mm) is required.
Ensure the range is installed so that the flow of combustion and ventilation air is not obstructed. Adequate clearance for air openings into the combustion chamber must be provided. Ensure sufficient air supply in the room for gas combustion at the burners.
For installation at ground level, adjust the four feet as necessary.
Installation Codes and Standards
Ranges must be installed in accordance with:
In the United States of America:
- State and local codes.
- National Fuel Gas Code, ANSI/Z223.1 (latest edition). Available from The American Gas Association, Inc., 1515 Wilson Blvd., Arlington, VA22209.
In Canada:
- Local codes.
- CSA B149.1 Natural Gas and Propane Installation Code.
- CSA C22.1 Canadian Electric Code.
- CSA C22.2 Canadian Electric Code.
These Canadian standards are available from the Canadian Standard Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6.
Backsplash Assembly
The standard Restaurant Range is equipped with a 23" (584 mm) high backsplash and shelf.
- Remove the backsplash components from the crating materials.
- Assemble the required components as shown in the diagrams.
- Tighten the four screws to secure the shelf.
- Lift the assembly up, sliding the channels into the space provided at the rear of the range.
- Install four #10 sheet metal screws (two to each channel leg).
Leveling
Check the leveling of the range. Place a level inside the oven cavity across the oven rack(s) to ensure it is level front-to-back and side-to-side.
To adjust leveling, tilt the range to one side and use channel locks to unscrew the adjustable leg insert as needed. Repeat for each leg. Optional casters are non-adjustable, so the floor must be level. An unlevel floor may cause cooking problems.
Gas Connections
CAUTION: All gas supply connections and any pipe joint compound used must be resistant to propane gases.
Each range is factory-equipped for the gas type specified on the rating plate. The installation gas connection is a 3/4" (19 mm) 14 FPT ANSI schedule #40 standard pipe. Ensure pipes are clean and free of obstructions. Codes require a gas shutoff valve in the gas line ahead of the range.
Standard ranges come with fixed burner orifices appropriate for installation elevation. Install the gas pressure regulator.
Before installing, ensure the supplied regulator matches the gas supply type indicated on the rating plate. The regulator is not factory installed; it is typically sealed in a plastic bag attached to the oven rack inside the oven cavity and must be field installed by a qualified installer.
Natural gas regulators are preset for 5" W.C. (Water Column) (.99 kPa); propane gas regulators for 10.0" W.C. (2.5 kPa).
- Locate the 3/4" (19 mm) gas connection pipe extending from the rear of the range.
- Apply leak sealant to pipe threads.
- Screw the regulator hand-tight onto the pipe, ensuring the regulator arrow points towards the range body back.
- Using a pipe wrench, tighten the regulator securely in an upright position.
The arrow on the regulator indicates the direction of gas flow. The pressure regulator must be mounted horizontally for proper preset outlet pressure. If mounted otherwise, the outlet pressure must be reset.
A leak limiter is supplied with each regulator to allow excess gas pressure to escape. Do not obstruct the leak limiter, as this can cause malfunction.
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS USING A SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
After checking for leaks, purge all gas piping to remove air. Before operation, verify the thermocouple is securely seated in the safety valve. Tighten the thermocouple a 1/4 turn past finger tight. DO NOT OVERTIGHTEN, as this can damage the thermocouple or safety magnet.
Testing the Gas Supply System
If gas supply pressure exceeds 1/2 psig (3.45 kPa), disconnect the range and its shutoff valve from the gas supply piping system.
If gas supply pressure is 1/2 psig (3.45 kPa) or less, isolate the range by closing its manual shutoff valve until ready for start-up.
WARNING: This product can expose you to chemicals, including Lead & Lead Compounds, known to the State of California to cause cancer, birth defects, or reproductive harm. To minimize exposure, always operate this unit according to the Owner's Manual and ensure proper ventilation. For more information, visit www.P65Warnings.ca.gov.
Flue Connections
DO NOT obstruct the flow of flue gases from the flue located on the rear of the range. It is recommended that flue gases be ventilated to the outside of the building via a system installed by qualified personnel.
A minimum clearance of 18" (457 mm) must be maintained from the termination of the flue to the filters of the hood venting system.
Information on ventilating hoods can be found in the standard for the "Removal of Vapors from Commercial Cooking Equipment", NFPA No. 96 (latest edition), available from The National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
