A.Gas Utility Rough-In Recommendations

The following gas system specifications are STRONGLY RECOMMENDED. Deviating from these recommendations may affect the baking performance of the oven.

Gas Meter

•One or two oven cavities: 750 cfh meter

•Three or four oven cavities: 1200 cfh meter

Gas Line

•DEDICATED LINE from the gas meter to the oven

•2" (50.8mm) pipe for natural gas

•1-1/2" (38.1mm) pipe for propane

•Maximum length: 200' (61m). Each 90° elbow equals 7' (2.13m) of pipe.

B.Connection

Check the oven’s gas supply requirements before making the gas utility connection. Gas supply requirements are listed on the oven’s serial plate (Figure 2-23) and in the Gas Orifice and Pressure Specifications table (Page 5 of this manual).

Check the serial plate to determine the type of gas (Propane or Natural) to be used with the oven.

Refer to the instructions in the gas hose package (included in the Installation Kit) before connecting the gas line. One gas line connection method is shown in Figure 2-25; however, compliance with the applicable standards and regulations is mandatory.

Inlet, regulated, and pilot gas pressure readings can be taken using a “U” tube manometer at the tap locations shown in Figure 2-26.

NOTE

The installation must conform with local codes or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1- latest edition.

In Australia, the installation must conform with AGA Code AG601 and with any requirements of the appropriate statutory authority.

CANADIAN:

CAN/CGA-B 149.1 Natural Gas Installation Code CAN/CGA-B 149.2 Propane Installation Code

Certain safety code requirements exist for the installation of gas ovens; refer to the beginning of Section 2 for a list of the installation standards. In addition, because the oven is equipped with casters, the gas line connection shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 (in U.S.A.), or, if appli- cable, Connectors for Movable Gas Appliances, CAN/CGA-6.16 (in Canada), as well as a quick-disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI Z21.41 (in U.S.A.), or, if applicable, Quick- Disconnect Devices for Use With Gas Fuel, CAN1-6.9 (in Canada).

C.Gas Conversion

Where permitted by local and national codes, it is possible to convert ovens from natural to propane gas, or from propane to natural gas. Use the appropriate Middleby Marshall Gas Conversion Kit for the specific oven model.

WARNING

The terms of the oven's warranty require all start-ups, conversions and service work to be performed by a Middleby Marshall Authorized Service Agent.
