SECTION 2 - INSTALLATION

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 - 650 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 and in Table 1-5, Gas Orifice and

Pressure Specifications (in Section 1, Description).

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 2-14; however,

compliance with the applicable standards and regulations is

mandatory.

Inlet and regulated gas pressure readings can be taken using

a U tube manometer at the tap locations shown in Figure 2-

15.

NOTE

In the USA, the installation must conform with local codes, or in

the absence of local codes, with the National Fuel Gas Code,

ANSI Z223.1.

In Canada, the installation must conform with local codes, or in

the absence of local codes, with the Natural Gas Installation

Code, CAN/CGA-B 149.1, or the Propane Installation Code,

CAN/CGA-B 149.2, as applicable.

In Australia, the installation must conform with AGA Code

AG601 and with any requirements of the appropriate statutory

authority.

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 Connec-

tors for Movable Gas Appliances, ANSI Z21.69 (in USA), or

Connectors for Movable Gas Appliances, CAN/CGA-6.16

(in Canada), AND

 A quick-disconnect device that complies with the Standard

for Quick-Disconnect Devices for Use With Gas Fuel, ANSI

Z21.41 (in USA.), or, if applicable, Quick-Disconnect De-

vices 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.

CAUTION

The terms of the oven's warranty require all start-ups, conver-

sions and service work to be performed by a Middleby Marshall

Authorized Service Agent.
