INSTALLATION PROCEDURES
3-16
NOTE: The dryer must be isolated from the gas supply piping system by closing its individual
manual shut off valve during any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5 kpa).
Figure.3-10 Typical of Gas Installation
Piping must be installed in accordance with good commercial steam system practice. Care
must be exercised when leveling steam dryers in 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, it should be dripped just before the control
valve with a proper trap and dirt pocket.
It is your responsibility to have ALL steam plumbing connections made by a qualified
professional to assure that the installation is adequate and conforms with local and state regulations
or codes.
IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in
component failure which will VOID THE WARRANTY.
