IMPORTANT: Failure to comply with these codes or
ordinances, and/or the requirements stipulated in this
manual, can result in personal injury and improper
operation of the dryer.
Each dryer must have its own manual shutoff valve to provide
isolation of the dryer from the gas supply.
The dryer 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 (3.5 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 system
at test pressures equal to or less than 1/2 psig (3.5 kPa).
IMPORTANT: Failure to isolate or disconnect the dryer
from supply as noted can cause irreparable damage to the
gas valve voiding the warranty.
!
WARNING
Fire or explosion could result due to failure of
isolating or disconnecting gas supply as noted.
Gas Supply
The gas dryer installation must meet the American National
Standard...National Fuel Gas Code ANSI Z223.1-LATEST
EDITION, or in Canada, the Canadian Installation Codes
CAN/CGA-B149.1 M91 (Natural Gas) or CAN/CGA-B149.2-
M91 (L.P. Gas) or LATEST EDITION, as well as local codes
and ordinances and must be done by a qualified professional.
NOTE: Undersized gas piping will result in ignition
problems, slow drying, increased use of energy, and can
create a safety hazard.
The dryer must be connected to the type of heat/gas indicated
on the dryer data label. If this information does not agree
with the type of gas available, do not operate the dryer.
Contact the reseller who sold the dryer or contact the
manufacturer.
IMPORTANT: Any burner changes or conversions must be
made by a qualified professional.
The input ratings shown on the dryer data label are for
elevations up to 2,000 feet (610 meters), unless elevation
requirements of over 2,000 feet (610 meters) were specified
at the time the dryer order was placed with the factory. The
adjustment or conversion of dryers in the field for elevations
over 2,000 feet (610 meters) is made by changing each burner
orifice. If this conversion is necessary, contact the reseller
who sold the dryer or contact the manufacturer.
IMPORTANT: This gas dryer is not provided with an
internal gas supply shutoff and an external gas supply
