Illustration G: Typical HeetSheet Installation
8. Install ThermoTube ® steam supply and return tubing to
collection manifolds and properly terminate all inlet and
outlet media connections using an FAK-7 end seal kit. The
steam supply should start at the highest point of the
HeetSheet so that flow is generally downward to avoid
trapping water during shutdown periods (see Illustration
G). Each panel should utilize a steam trap to prevent pref-
erential steam flow.
9. In situations where excessive moisture is expected or ther-
mal insulation will not be installed immediately following
HeetSheet installation, flashing should be installed using
waterproof mastic to prevent water from accumulating
behind the panel.
Inspection of System . . .
1. Thoroughly inspect banding after installation is complete
to verify proper tension.
2. After all connections to the supply header and collection
manifolds have been completed, test the circuit for leaks
by subjecting it to steam pressure equal to or greater than
that which is to be used in the system or preferably with
suitable hydrostatic tests. Repair any leaks and retest the
system.
