INSTALLATION
1. Damage Check: check carton or crate for possible
damage incurred in shipping. After carefully uncrating,
check for “concealed” damage. Report any damage
immediately to your carrier.
2. The correct type of gas for which the unit was
manufactured is noted on the rating plate, and this type
of gas must be used.
3. The gas pressure must be checked when the unit is
installed, to ensure that the unit gas pressure is the same
as specified on the rating plate. If necessary pressure
adjustments can be made at the pressure regulator,
supplied on each unit.
4. Have a qualified gas technician check the gas pressure
to make certain that existing gas facilities (meter, piping,
etc.) will deliver the BTU’s of gas required at the unit with
no more than ½” water column pressure drop. When
checking pressure, be certain that all the equipment on
same gas line is turned to the “ON” position.
5. Make certain that the new piping, joints and connections
have been made in a clean manner and have been
purged, so that the piping compound, chips, etc will not
clog pilots, valves and / or controls. Use pipe joint sealant
that is certified for use with LP gas.
6. WARNING; check gas connections for leaks, using soap
solution or similar means. DO NOT CHECK WITH AN OPEN
FLAME.
Rating Plate
All burner-input ratings are shown on the serial plate located
on the right side panel of the appliance.
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 affixed to the unit contains this information.
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.
Gas Connections
The inlet manifold size for connection to the main gas supply
is (1) 3/4” NPT inlet for each deck.
The importance of 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 with
the Nation fuel code, ANSI Z223.1, Natural Gas Installation
code, CAN/CGA-B149.1, or the Propane Installation code,
CAN/CGA-B149.2, as applicable, including:
1. 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 (3.45 kPa).
2. 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).
Before assembly and connections, check gas supply.
A. The type of gas for which the unit is equipped is stamped
on the data plate located behind lower front panel.
Connect a unit stamped “NAT” only to natural gas;
connect those 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 ½” water column pressure drop.
NOTE: When checking pressure be sure that all other
equipment on the same gas line is on. A pressure regulator is
supplied with GARLAND Pizza Ovens. Regulator is preset to
deliver gas at pressure shown on the rating plate.
