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 these codes or ordinances,
and/or the requirements stipulated in this
manual, can result in personal injury and improper
operation of the dryer.
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).
Failure to isolate or disconnect the dryer from supply as
noted can cause irreparable damage to the gas valve,
voiding the warranty.
Note
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).
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 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 the manufacturer.
Impor tant
Any burner changes or conversions must be
made by a qualified professional.
The input ratings shown on the 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 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 outlet side of gas valve pressure tap when gas valve is on.
Gas Connections
Inlet connection ............... 1/2” N.P.T.
Inlet supply size ............... 1/2” Diameter Pipe (minimum)
Heat input (per dryer)....... 150,000 Btu/hr (37,799 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 (14.92 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 (26.1 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 .......... #19 = 0.1660” (4.2164 mm).
L.P. Gas ................ #43 = 0.0890” (2.2606 mm).
