FLEXIBLE CONDUIT INSTALLATION (Continued)
Installation Instructions
Note:
Do not add any type of lubricants inside or on the flexible
conduit. Make certain stainless steel wire rope is clean and
debris-free.
The flexible conduit should be routed along the same path that
EMT conduit would normally be run. Stainless steel wire rope
should be routed through the flexible conduit as it is in EMT
conduit.
CAUTION
Flexible conduit must not be located within 6 in. (152 mm) of
the hood or in areas exceeding 130 °F (54 °C). also, do not
route flexible conduit in areas where conduit can be crushed,
pinched, or broken.
Flexible conduit can be used to connect a PYRO-CHEM control
head to a remote pull station or mechanical gas valves.
Before starting the system installation, take a few minutes to
plan the layout of the system. This will minimize the amount of
components needed to complete the installation. Once the path
of the flexible conduit has been determined, verify that the layout
does not exceed the design requirements.
Connecting the Flexible Conduit to the PYRO-CHEM
Control Head, Electrical Box, Pull Station, or Mechanical
Gas Valve
1. Layout the flexible conduit and secure it in place.
Note:
If
inner liner is crimped, turn a drywall screw into the end to
open it. See Figure 4-39.
