Checklist Before Installation
Placement
The valve train should be installed in an accessible
ventilated location, level to a horizontal or vertical position,
and supported to solid structural elements. Locate the
valve train to avoid excessive numbers of bends and
fittings in the interconnecting piping.
Access
Provide ready access to the manual valves and test ports
for maintenance and testing.
Environment
The components should be mounted in an area that will be
within the environmental conditions specified in
Datasheets 791-3 or 791-4. Check the following items:
• Voltage, frequency and stability of the electrical
power
• Ambient temperature and humidity
• Area classification is non-hazardous
• Exposure to sunlight, water, ice, wind, and vibration
Preparation for Installation
Protect and prevent contamination of the piping during
installation. Remove any packing and shipping materials
and inspect for foreign objects in the piping.
Ŷ
Make sure all devices are properly oriented with
respect to flow direction and vertical (gravity)
orientations.
Ŷ
Avoid severe size reductions in pipe connections,
unnecessary fittings, and excessive numerous
bends that may cause additional flow restriction
and pressure loss.
Installation
Mechanical Support
The installation must comply with local gas piping codes.
Brackets or hangers must support the gas piping at
intervals short enough to support the weight and to damp
out excessive vibration. Provisions shall be made for
expansion and contraction and for structural settlement
that may affect the piping.
Flow
The valve train segments and components are
manufactured to allow flow in only one direction. Verify
that the flow direction is correct. See Figure 3.1 through
Figure 3.3 for proper flow direction.
