Gas Piping Installation
GAS PIPING
INSTALLATION
NATURAL GAS ONLY
1.
Gas service installation must conform with local codes, or in
the absence of local codes with the National Fuel Gas Code,
ANSI Z223.1 or the CAN/CGA-B149, Installation Codes.
2.
Check rating plate located on rear wall of dryer, for type of
gas to equip the dryer and the altitude (elevation).
3.
Check with the gas supplier for the gas pressure and the
proper gas supply line installation.
NOTE: The dryer and its individual shutoff valve must be discon-
nected from the gas supply piping system during any pressure testing
of that system at test pressures in excess of 1/2 psi (3.5 kPa).
The dryer 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 greater
than 1/2 psi (3.5 kPa).
CAUTION: Low gas pressure and intermittent gas will cause gas
ignition problems. This will cause inadequate drying of the clothes
load.
NATURAL GAS ONLY: Check the gas pressure inlet supply to the
dryer, 11 inches WC pressure maximum. Check the manifold pressure,
3.5 inches WC pressure inside the dryer.
CAUTION: Gas loop piping must be installed as shown on the previ-
ous page, to maintain equal pressure for all dryers connected to a
single gas service. Install other gas appliances upstream from the
loop.
Specific gas pipe size should be obtained from your supplier or refer to the
Gas Pipe Size Chart in this manual.
