INSTALLATION
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.
Before assembly and connection, check gas supply.
A. The type of gas for which the unit is equipped is stamp on
the date plate located behind 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 pressure to make certain that existing
meter and piping will supply fuel at the unit with not
more than 1/2" water column pressure drop.
NOTE: When checking pressure be sure that all other
equipment on the same gas line is on. An internal pressure
regulator is supplied with GARLAND Convection Ovens.
Regulator is preset to deliver gas at pressure shown on the
rating plate.
The appliance 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 (3.45kPa.).
The appliance must be isolated from the gas supply piping
system by closing its individual manual
shut-off valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than
1/2 PSI (3.45 kPa).
Rating Plate
When corresponding with the factory or your local
authorized factory service center regarding service problems
or replacement parts, be sure to refer to the particular unit
by the correct model number (including the prefix and suffix
letters and numbers) and the warranty serial number. The
rating plate located behind the lower front panel contains
this information.
Part # 1844082 (11/03/08)
We suggest installation, maintenance and repairs should be
performed by your local authorized service agency listed in
your information manual pamphlet.
In the event you have any questions concerning the
installation, use, care or service of the product, write or call
our Product Service Department.
This product must be installed by professional personnel as
specified. Garland/U.S. Range products are not approved or
authorized for home or residential use, but are intended for
commercial applications only. Garland / U.S. Range will not
provide service, warranty, maintenance or support of any
kind other than in commercial applications.
Clearances
Combustible and Non-Combustible Wall Clearance:
Side:
1.0" (25mm)
Rear:
1.0" (25mm)
NOTE: Adequate clearance must be provided for servicing
and proper operation.
Gas Connections
A readily accessible gas shut off valve of an approved type
must be installed in the gas supply line upstream of the
unit's pressure regulator. A pipe joint compound resistant to
liquefied petroleum gases should be used on all pipe joints.
The American National Standards Institute mandates the
use of a pressure regulator on all commercial cooking
equipment. Garland provides an approved internal pressure
regulator with each unit.
When piping the gas supply for a double stack unit, note that
the supply inlet is 1" NPT as opposed to 3/4" for the single
deck. An undersized gas supply line may restrict the flow of
gas and affect the performance of the appliance. If there are
other gas appliances supplied by the same supply line, the
line must be sized to carry the combined volume without
suffering a pressure drop of more than 1/2" water column at
the manifold of each appliance on the line at full rate.
