Piping Connections
For threaded connections, ensure that pipe sealing tape
or compounds do not enter inside the pipe. It is good
practice to leave the first 2 threads bare to prevent the
tape or compound from entering inside the pipe. Use
sealing methods that are compatible with the gas and
piping materials and that are accepted by the local
authority.
For flange connections, ensure that the faces of flanges,
bolt, and nut bearing areas are clean and smooth.
Adjoining flange faces must be parallel to prevent
overstraining the flange to achieve a gas-tight joint. Do not
use a joint compound on the faces and gaskets without
checking its compatibility with the gasket material.
First loosely install and align the gasket and bolts. Then
tighten the bolts in a diagonal pattern while keeping the
pressure evenly distributed. Take care to avoid undue
strain on valves, fittings, and other accessories. Do not
install undersized bolts to make up for misalignment of
bolt holes.
Electrical Wiring
All electrical wiring must be done in accordance with the
national electrical code, the local utility company and
municipal agency requirements. Before making any
electrical connections, compare the electrical supply
circuit ratings at the installation site to those on the
nameplates of the devices being wired. Check the
individual component datasheets for specific ratings.
Checklist After Installation
To verify the system was properly installed, perform the
following checks:
• The valve train is securely mounted
• Flow is in the proper direction
• Check and make provisions to guard against
accidental damage
• Ensure there are no loose components or conduits
• All wiring connections are tight
• Access covers are in place and tightened
• Verify all device orientations are correct with respect
to flow direction
• Ensure that it is in accordance with the equipment
system design
