American Dryer Corp. AD-15 Phase 7 - Manual (Page 14)

12 American Dryer Corp. 113243-1
GAS INFORMATION
It is your responsibility to have ALL plumbing connections
made by a qualified professional to ensure that the gas
plumbing installation is adequate and conforms with local
and state regulations or codes. In the absence of such codes,
ALL plumbing connections, materials, and workmanship
must conform to the applicable requirements of the 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 (Liquid Propane [L.P.]
Gas) or LATEST EDITION.
IMPORTANT:
Failure to comply with codes or ordinances, and/
or requirements in this manual, can result in
personal injury and improper operation of the
dryer.
The dryer and its individual shutoff valves 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 test 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, which will VOID THE
WARRANTY.
WARNING:
FIRE OR EXPLOSION COULD RESULT due
to failure of isolating or disconnecting the 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 ADC factory.
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 (609.6 meters), unless elevation
requirements of over 2,000 feet (609.6 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 (609.6 meters) is made by changing each
burner orifice. If this conversion is necessary, contact the
reseller who sold the dryer or contact the ADC factory.
IMPORTANT:
This gas dryer is not provided with an internal
gas supply shutoff and an external gas supply
shutoff must be provided.
Technical Gas Data
Gas Specifications
Shaded areas are stated in metric equivalents
* Measured at outlet side of gas valve pressure tap when the gas valve is on.
Gas Connections
Inlet connection 1/2” N.P.T.
Inlet supply size 1/2” pipe (minimum)
Btu/hr input 50,000 (12,600 kcal/hr)
Natural Gas
Regulation is controlled by the dryer’s gas valve’s internal
regulator. Incoming supply pressure must be consistent
between a minimum of 6.0 inches (14.92 mb) and a
maximum of 12.0 inches (29.9 mb) water column (W.C.)
pressure.
Liquid Propane (L.P.) Gas
Dryers made for use with L.P. gas have the gas valve’s
internal pressure regulator blocked open so that the gas
pressure must be regulated upstream of the dryer. The
pressure measured at each gas valve pressure tap must
be a consistent 10.5 inches (26.1 mb) water column.
There is no regulator or regulation provided in an L.P.
dryer. The water column pressure must be regulated at
the source (L.P. tank) or an external regulator must be
added to each dryer.
Shaded area is stated in metric equivalent
* Drill Measurement Size (D.M.S.) equivalents are as follows:
Natural Gas #41 = 0.0960” (2.4384 mm).
Liquid Propane Gas #54 = 0.0550” (1.397 mm).
Piping Connections
ALL components/materials must conform to National Fuel
Gas Code Specifications ANSI Z223.1-LATEST EDITION, or
in Canada, CAN/CGA-B149.1-M91 (Natural Gas) or CAN/
CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST
EDITION (for General Installation and Gas Plumbing), as well
as local codes and ordinances and must be done by a
qualified professional. It is important that gas pressure
regulators meet applicable pressure requirements, and that
gas meters be rated for the total amount of ALL the appliance
Btus being supplied.
