Gas Piping - Eclipse Winnox WX Series Installation Manual

Gas Piping

Burner Piping
The burner is factory assembled and shipped as ordered.
NOTE: If it is necessary to redirect piping, remove the
outer four bolts only
replace bolts. When reassembling, be sure that:
• ratio regulator spring column
• the bypass regulator spring column is pointing up
• arrow on the ratio regulator points in the direction of
gas flow
• integral fuel orifice and o-rings
• the same straight run of pipe
the ratio regulator and the burner.
Do not attempt to redirect piping by removing the
inner circle bolts
damaged.

• For applications in which the Winnox is
operating indoors, a vent limiting device is
installed in the bypass regulator.
• For applications in which the Winnox is
operating outdoors, an insect/rain protector is
installed in the bypass regulator.
Supply Piping
Inlet pressure to the ratio regulator must stay within
specified limits. Refer to the appropriate Winnox
datasheet, series 111.
• Locate the valve train close to the burner. The gas
must reach the burner during the fixed trial for
ignition period.
• Sufficiently size the shut off valve in the valve train.
• Make sure piping is large enough to accommodate
flow required to meet burner input.
• Minimize piping elbows.
• Install fuel flow measurement device
from the burner inlet.
• If necessary to maintain inlet pressures to the
burner (see datasheet for your burner), install a gas
pressure regulator
and downstream of the valve train and fuel
measurement device

Pipe Connections
Installation of a pipe union in the gas line is recommended
to simplify burner removal.
Use of flexible pipe is optional.
NOTE: Flexible pipe causes higher pressure drops than
standard pipe. Consider this when sizing your gas lines.
