Make sure the gasket is installed between the mounting flange and the chamber wall. Locate the end of
the ceramic combustor between 10mm and 50mm inside furnace wall. Clearance hole in the chamber
wall must be between 120mm and 180mm in diameter. Pack the gap with ceramic fiber as stated above
to the dimensions shown.

Layout
Install the piping as shown in the schematics. Refer to
chapter 3 of the ExtensoJet Design Guide No. 230.
Support the Piping
Use brackets or hangers to support the gas piping. If you have
questions, consult your local gas company.
Straight Run of Pipe Before a Metering Orifice
Note:
There must be a run of pipe with a straight length of at
least 10 pipe diameters before the burner metering orifice.
If you do not do this, the pressure readings will be
inaccurate.
Pipe Connections
1. Install a pipe union in the gas line to the burner. This simplifies
removal of the burner.
2. The use of flexible pipe nipples in the gas line to the burner is
optional. Flexible nipples can absorb stress due to heat
expansion and slight misalignment.
Note:
Flexible pipe nipples will cause inaccurate metering orifice
readings and may cause higher pressure drops than
equivalent standard pipe. Consider this when you size the
gas lines.
Avoid Large Pressure Drops
Note:
The pressure drop of the gas in the piping is a critical
parameter. Make sure that the size of all the piping is large
enough to prevent excessive pressure losses.
