INSTALLATION
Statutory Regulations
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
specications. 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/GCA-B149.1
or the Propane Installation Code, CAN/CGA-B149.2, as
applicable.
Gas Connections
Before assembly and connection, check gas supply.
A. The type of gas for which the unit is equipped is stamped
on the data plate located on the lower front frame,
simply remove the drip pan for easy access. 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
sucient amount of gas pressure required to operate the
unit.
C. If it is additional equipment or replacement have a
qualied 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 1/2” water column pressure drop. When checking
pressure, be certain that other equipment on the same
gas line is on at full rate.
NOTE: When checking pressure, be sure that all other
equipment on the same gas line is on. A pressure regulator is
supplied with Garland Infra-Red Broilers. Regulator is preset
at deliver gas at pressure shown on the rating plate.
D. The appliance and its individual shut o (supplied by
others) must be disconnected from the gas supply piping
system during any pressure testing of that system at
pressures in excess of 1/2” psi (3.45 kPa).
E. The appliance must be isolated from the gas supply
piping system by closing its individual manual shut o
valve (supplied by others) during any pressure testing of
the gas supply piping system at test pressures equal to or
less than 1/2 psi (3.45 kPa).
F. Gas supply connection is made in back lower left hand
corner of unit. A readily accessible approved type of hand
valve should be installed on each supply line. Test for
leaks – DO NOT USE ANY OPEN FLAME.
G. A pressure tap plug is supplied with the units and it is
installed on the manifold. The drip pan must be removed
to use the pressure tap. The gas pressure must be
checked when the unit is installed, to insure that the unit
gas pressure is the same as specied on the rating plate.
If necessary, pressure adjustments must be made at the
pressure regulator, supplied on each Infra-Red Broiler.
NOTE: the pressure regulator is located at the top rear of the
salamander.
H. If it is completely new installation, have gas lines, meter
size piping and piping installed and checked by a
qualied gas technician.
I. 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 resistant to liqueed petroleum gas.
WARNING Check gas connections for leaks. Use a soap
solution or similar means. DO NOT USE AN OPEN FLAME!
Note: This appliance is not recommended for residential
installation.
Pressure Regulators in Battery Installations
1. Must have a maximum regulation capacity for the total
connected load.
2. The pressure regulator(s) installed must be listed by a
nationally recognized agency.
3. The pressure regulator(s) must have a pressure
adjustment range to allow adjustment to the manifold
pressure on the appliance rating plate.
4. Unless the manifold pressure on all connected appliances
is the same, a separate regulator must be supplied for
each appliance(s) having dierent manifold pressures.
5. Gas supply lines may be connected at right, left or
both ends of a battery or at the tee connections on
spreader plates. If ve (5) or more units are placed in a
battery, more that one (1) supply line should be used. A
readily accessible, approved type of hand shut o valve
(supplied by others) should be installed on each supply
line.
