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 to 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 (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 piping 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 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 shutoff
must be provided.
Technical Gas Data
Gas Specifications
Shaded areas are stated in metric equivalents
* Measured at 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)
Heat input (per dryer) ...... 78,000 Btu/hr (19,656 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 in WC (19.92 mb) and a maximum
of 12.0 in WC (29.9 mb) pressure.
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 in
WC (26.2 mb). There is no regulator or regulation provided in
an L.P. dryer. The 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
* D.M.S. equivalents are as follows:
Natural Gas.....................#31 = 0.1200” (3.048 mm).
L.P. Gas ..........................#50 = 0.0700” (1.778 mm).
