Part # 1382698 (02/26/08)Page 6
INSTALLATION Continued
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 ow 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 eld, but it is
recommended that they not be tampered with unless that
part is known to be out of adjustment or serious pressure
uctuations are found to exist and can be solved no other
way. Any adjustments to regulators must be made by
qualied service personnel with proper test equipment.
WARNING Do not connect the regulator inside the unit’s
body or directly on top of the hot plate, 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 orices 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 exible couplings and/or
quick-disconnect ttings, 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
specied.
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.
Manual Pilot Valve
All burners are equipped with constant-burning pilots. These
should be manually lighted immediately after the gas is
turned on and the system is checked for leaks. An adjustment
screw for each pilot is located on the gas manifold and can
be accessed through openings in the valve panel between
the valve knobs.
Testing and Adjustments
Check all gas connections for leaks using a soapy solution
before lighting any pilots. DO NOT USE OPEN FLAME
TO CHECK FOR LEAKS! Putting open ame beside a new
connection is not only dangerous, but will often miss small
leaks that a soapy solution would nd.
All U.S. Range appliances are adjusted and tested before
leaving the factory, eectively matching them to sea
level conditions. Adjustments and calibrations to assure
proper operation may be necessary on installation to meet
local conditions, low gas pressure, dierences in altitude;
variations in gas characteristics, to correct possible problems
caused by rough handling or vibration during shipment, and
are to be performed only by qualied service personnel.
These adjustments are the responsibility of the customer,
installer and/or dealer and are not covered by the U.S. Range
warranty.
