INSTALLATION Continued
National Code Requirements
Safe and satisfactory operation of your equipment depends,
to a great extent, on its proper installation. 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, including:
1. The appliance and its individual shutoff 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 shutoff
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)
Manual Shut-Off Valve
This installer-supplied valve must be installed in the gas
service line ahead of the appliance and regulator in the gas
stream and in a position where it can be reached quickly
in the event of an emergency. If the Salamander is ranged
mounted, a separate shut-off valve should be on the line to
the unit.
Pressure Regulator
All heavy-duty, commercial cooking equipment must have
a pressure regulator in the incoming service line for safe and
efficient operation, since service pressure may fluctuate with
local demand. The manual shut-off valve is normally supplied
by the installer, but pressure regulators are shipped from U.S.
Range with every hot plate.
Regulators are pre-set at the factory for 5” WC (natural gas)
or 10” WC (propane) according to the customer’s ordering
instructions.
Prior to connecting the regulator, check the incoming line
pressure, as these regulators can withstand a maximum
pressure of 1/2 psi (14” WC). If the Line pressure is beyond
this limit, a step-down regulator will be required. Double-
check the arrow forged onto the bottom of the regulator
body which shows gas flow directions; it should point
downstream to the appliance. The red air-vent cap is part of
the regulator and should not be removed unless local codes
require external venting.
Regulators can be adjusted in the field, but it is
recommended that they not be tampered with unless that
part is known to be out of adjustment or serious pressure
fluctuations are found to exist and can be solved no other
way. Any adjustments to regulators must be made by
qualified service personnel with proper test equipment.
WARNING Do not connect the regulator inside the unit’s
body or directly on top of the salamander, as temperatures
are high enough in these areas to destroy the regulator.
Failure to install a pressure regulator will void the
equipment warranty!
Rigid Connections
Double-check any installer-supplied intake pipes visually
and clear any dirt particles, threading chips, or other foreign
matter before installing in a service line. Those particles will
clog orifices when gas pressure is applied.
WARNING All connections must be sealed with a joint
compound suitable for LP gas, and all connections must be
tested with a soapy solution before lighting any pilots!
Flexible Couplings & Connectors.
If the unit is to be installed with flexible couplings and/or
quick-disconnect fittings, for an appliance equipped with
casters, the installation shall be made with a connector that
complies with the Standard for Connectors for Movable Gas
Appliances, ANSI Z21.69 /CSA 6.16, and a quick-disconnect
device that complies with the Standard for Quick-Disconnect
Devices for Use With Gas Fuel, ANSI Z21.41 / CSA 6.9, and
adequate means must be provided to limit the movement
of the appliance without depending on the connector and
the quick-disconnect device or its associated piping to limit
the appliance movement and the location(s) where the
restraining means may be attached to the appliance shall be
specified.
Further, if the unit is to be installed on a non-combustible
surface that is equipped with casters, means must be
provided to limit the movement of the unit on this surface.
