Steam Information - ADC ML-30V Installation Manual

Propane Gas
Dryers made for use with propane 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 a propane dryer. The pressure
must be regulated at the source (propane tank) or an external
regulator must be added to each dryer.

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 (Propane 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 Btu being
supplied.
Installer within Australia – refer to AS/NZS5601.1 for
guidance on gas supply pipe sizing required for this
appliance installation.
The dryer is provided with a 1/2" N.P.T. inlet pipe connection
extending out the back area of the burner box. The minimum
pipe size (supply line) to the dryer is 1/2" diameter. For
ease in servicing, the gas supply line of each dryer must
have its own shutoff valve.
The size of the main gas supply line (header) will vary
depending on the distance this line travels from the gas
meter or, in the case of propane gas, the supply tank, other
gas-operated appliances on the same line, etc. Specific
information regarding supply line size should be determined
by the gas supplier.
NOTE: Undersized gas supply piping can create a low or
inconsistent pressure, which will result in erratic operation
of the burner ignition system.
A plugged tap 1/8" N.P.T. minimum, accessible for a
pressure gauge connection, must be installed in the main
gas supply line immediately upstream of the dryers.

Steam Information ___________________

It is your responsibility to have all plumbing connections
made by a qualified professional to ensure that the steam
plumbing installation is adequate and conforms with local
and state regulations or codes.
Care must be exercised when leveling steam dryers into
final position. After leveling the dryer, check the downward
pitch of the heat exchanger from front to rear with a level.
Likewise, check the downward pitch of the return condensate
manifold toward its outlet part. Absence of these downward
pitches will result in probable water hammer and premature
heat exchanger fracture and leakage.
The presence of condensate in the steam will cause water
hammer and subsequent heat exchanger failure. The steam
supply connection must be taken from the top of a
well-dripped steam main. If the supply run-out to the dryer
exceeds 20 feet (6.1 meters), it should be dripped just before
the control valve with a proper trap and dirt pocket.
IMPORTANT: Failure to comply with the requirements
stipulated in this manual can result in component failure,
which will void the warranty.
NOTE: This dryer is manufactured with a pneumatic
(piston) damper system, which requires an external
supply of air (80 psi +/- 10 psi [5.51 bar +/- 0.68 bar]).
