Garland MP-GS, MP-GD-10-S service manual Installation, GAS Connections, Location, Wall Clearance

INSTALLATION

It is the responsibility of the purchaser to ensure the oven is installed in a manner to meet all local codes.. In the absence of local codes, applicable national codes are referenced in this booklet.. In the case of discrepancy between the information in this booklet and local codes, it is recommended you consult your local inspector(s).. This appliance meets or exceeds all applicable regulations and standards in effect on its date of manufacture..

Location

The importance of the proper installation of Commercial Gas Cooking Equipment cannot be over stressed.. Proper performance of the equipment is dependent, in great part, on the compliance of the installation with the manufacturer’s specifications.. Installation must conform to local codes or, in the absence of local codes, with the National Fuel Code, ANSI Z223..1, Natural Gas Installation Code, CAN/CGA-B149..1, or the Propane Installation Code, CAN/CGA-B149..2, as applicable..

Wall Clearance

This oven, single or stacked, must be installed with adequate clearance to combustible and non-combustible walls..

Sides:	1 inch [25 mm]
Back:	3 inches [76 mm] for gas ovens, and
	6 inches [152 mm] for electric ovens..

Garland recommends that a one inch clearance be maintained between this oven and any other cooking appliance..

Garland recommends that this oven not be installed with a broiler or open burner appliance immediately adjacent to the right side..

Each appliance shall be located with respect to building construction and other equipment so as to permit access to the appliance.. Such access and clearance may be necessary for servicing and cleaning..

GAS CONNECTIONS

The type of gas for which the oven is equipped is stamped on the data rating plate.. It is located inside the lower front trim cover.. Connect an oven stamped “NAT” to natural gas only.. Connect an oven stamped “PRO” to propane gas only..

If the oven is being installed into a new location, have gas authorities check the meter size and piping to assure the supply line has a sufficient amount of gas pressure to operate the oven..

If the oven is a replacement or additional appliance to an existing installation have gas authorities check the pressure to ensure the existing meter and pressure will supply the oven with no more than a 1/2” water column pressure drop..

Note:  When checking the gas pressure make sure all other appliances on the same gas line are turned on..

A pressure regulator is supplied with Garland convection ovens.. The regulator pressure is preset to deliver the gas at the pressure shown on the rating plate.. Do not install an additional regulator where the unit connects to the gas supply unless the gas pressure exceeds the maximum recommended pressure..

The oven and its individual shut-off valve 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..45 kPa)..

The oven must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the supply system at test pressures equal to or less than1/2 PSI (3..45 kPa)..

Part # MPSM07 (03/24/08)

Prior to connecting to the building gas supply the lines should be purged of all metal filings, pipe thread compound or other debris..

The gas connection piping (3/4” for single ovens, 1” for stacked ovens), must be considered when planning the supply line.. Undersized gas supply lines may restrict the gas flow and affect performance.. If other gas appliances are supplied by the same supply line, it must be sized to carry the combined volume required for all the appliances without causing a more than 1/2” pressure drop at the manifold of each appliance on line at full rate..

Recommended supply pressures are 7” ± 5% WC for natural gas (NAT) and 11” ± 5% WC for propane (PRO).. The inlet pressure for the supply line must not exceed 13..8”WC natural and 15”WC for propane..

Two ovens stacked may be supplied by a single gas line.. The minimum recommended size of a single supply line for two stacked ovens is 1 inch..

Assemble the gas pipes and fittings provided in the stacking kit as shown in the Figure 3 on page 7.. Use a pipe thread compound that is intended for use on propane gas piping..

Be sure to check for leaks before finalizing the installation.. Use appropriate solutions or detection devices..

Installations in which a flexible gas connection hose is used, require the supplied strain relief to be installed at the lower left rear corner of the base.. Install the strain relief in accordance with applicable codes.. The strain relief must limit the movement of the oven to prevent unnecessary stress on the flexible connector..
