Gas Connections - Garland G Serie Manual De Instalación Y Operación

INSTALLATION Continued

Gas Connections

All fixed (non mobile) appliances MUST be fitted with a
manual gas cock upstream of the appliance to provide a
means of isolation for servicing or cleaning purposes . A
union or similar means of disconnection must be provided
between the gas cock and the appliance .
A manually operable valve must be fitted to the gas supply
to the kitchen to enable it to be isolated in an emergency .
Whenever practical, this shall be located either outside the
kitchen or near an exit in a readily accessible position .
Where it is not practical to do this, an automatic isolation
valve system shall be fitted which can be operated from a
readily accessible position or near to the exit .
At locations where the manual isolation valve is fitted or
the automatic system can be reset, a notice MUST be fitted
stating:
"ALL DOWNSTREAM BURNER AND PILOT VALVES MUST
BE TURNED OFF PRIOR TO ATTEMPTING TO RESTORE THE
SUPPLY . AFTER EXTENDED SHUT OFF, PURGE BEFORE
RESTORING GAS . "
Before assembly and connection, check gas supply .
A . The type of gas for which the unit is equipped is stamped
on the rating plate located on the lower front panel
simply remove the drip tray for easy access . Connect a
unit stamped "NAT" only to natural gas; connect those
stamped "PRO" only to propane gas .
B . If it is additional equipment or a replacement have a
qualified gas technician check the gas pressure to make
certain that existing gas facilities (meter piping, etc .)
will supply gas to the unit with no more than 1/2" water
column pressure drop .
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 cheesemelters . The
regulator is preset to deliver gas at the pressure shown on
the rating plate .
Part # 4526027 (01/07/09)
C . The appliance and its individual shut off (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) .
D . The appliance must be isolated from the gas supply
piping system by closing its individual manual shut off
valve (supplied by others) during any pressure testing of
the gas supply piping system at test pressures equal to or
less than1/2 psi (3 .45 kPa) .
E . The gas supply connection is made either at the top left
rear or lower rear right corner, depending on how the
unit was ordered . A readily accessible approved type of
hand valve should be installed on each supply line . Test
for leaks – DO NOT USE ANY OPEN FLAME .
F . The gas pressure must be checked when the unit is
installed, to insure that the unit gas pressure is the same
as specified on the rating plate . If necessary, pressure
adjustments must be made at the supplied pressure
regulator .
NOTE: the pressure regulator is located at the top left rear or
bottom right rear of the cheesemelter .
G . If it is a completely new installation, have a qualified gas
technician check meter size and piping to ensure that
the unit is supplied with a sufficient amount of gas at the
specified pressure for unit operation .
H . 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 liquefied petroleum gas .
WARNING Check gas connections for leaks . Use a soap
solution or similar means . DO NOT USE AN OPEN FLAME!
