NOTICE
Installation must comply with
National Fuel Gas Code, ANSI Z223.1
,
Natural Gas Installation Code,
CAN/CGA-B149.1
, or the
Propane Installation Code, CAN/CGA-B149.2
, as applicable.
Local codes regarding installation vary greatly from one area to another. The National Fire Protection
Association, Inc. states in its NFPA 96 latest edition that local codes are the “authority having
jurisdiction” when it comes to installation requirements for equipment. Therefore, installations should
comply with all local codes.
Southbend reserves the right to change specifications and product design without notice. Such
revisions do not entitle the buyer to corresponding changes, additions, or replacements for previously
purchased equipment.
This product is intended for commercial use only, not for household use.
GAS SUPPLY
The Serial Plate is located on the interior side of the valve panel (see Figure 1 on page 3). It indicates the
type of gas the unit is equipped to burn. All Southbend equipment is adjusted at the factory. Check type of
gas on serial plate.
These models are design-certified for operation on natural or propane gases. The unit is shipped configured
for natural gas. A kit for conversion to using propane gas is included (see instructions in kit or page 9 of this
manual).
This appliance should be connected ONLY to the type of gas for which it is configured.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas
required for satisfactory performance. Fluctuations of more than 25% on natural gas or 10% on propane gas
will create problems and affect burner operating characteristics. A 1/8" pressure tap is located on the
manifold to measure the manifold pressure.
An adequate gas supply line to the unit should be no smaller than the inside diameter of the pipe from the
unit to which it is connected.
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.
All pipe joints and connections must be tested thoroughly for gas leaks. Use only soapy water for testing on
all gases. NEVER use an open flame to check for gas leaks. All connections must be checked for leaks after
the unit has been put into operation. Test pressure should not exceed 14" W.C.
!
CAUTION
THIS 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 PSIG (3.45 kPa).
THIS 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 PSIG (3.45
kPa).
