Gas Supply; Statutory Regulations; Manual Shut-Off Valve; Pressure Regulator - U.S. Range “REGAL” SERIES Installation And Operation Manual

INSTALLATION Continued
Means must be provided for any commercial, heavy-duty
cooking appliance to exhaust combustion waste products to
the outside of the building. Usual practice is to place the unit
under an exhaust hood; the minimum should be an exhaust
fan mounted above the unit Filters and drip troughs should
be part of any industrial hood, but consult local codes before
construction and installing a hood.
Strong exhaust fans in this hood or in the overall air
conditioning system can produce a slight vacuum in the
room and/or cause air drafts, either of which can interfere
with pilot or burner performance and be hard to diagnose.
Air movement should be checked during installation; if
pilot/burner outage problems persist, make-up air openings
or baffles may have to be provided in the room.

Gas Supply

1. Installation of the equipment should be made by a
licensed plumber.
2. A gas shut-off valve must be installed in the gas supply
line ahead or the appliance for safety and for ease of
future service.
3. A gas pressure regulator must be installed at the
appliance prior to connecting the equipment to the gas
line. Failure to install a regulator will void the equipment
warranty.
NOTE: The gas supply (service) line must be the same size or
greater than the inlet line of the appliance. U.S. Range Stock
Pots use a 3/4" NPT inlet. Sealant on all pipe joints must be
resistive to LP gas.

Statutory Regulations

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)
Part # 1382699 (02/26/08)

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.

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 stock pot.
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 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!
