Checklist After Installation; Refractory Block Curing Schedule - Eclipse Furnnox 210 Series Installation Manual

NOTICE
■ After initial firing of the furnace at design
temperature, check for fiber shrinkage in the
vicinity of the refractory combustor. Fill any voids
with bulk fiber insulation to maintain a gas-tight
seal between the furnace interior and shell.
Piping Installation
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
Install a pipe union in the gas line to the burner. This
simplifies removal of the burner.
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: 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 loses.

Checklist After Installation

To verify the system was properly installed, perform the
following checks:
1. Make sure that there are no leaks in the gas lines and
the air lines.
2. Make sure all the components of the flame monitoring
control system are properly installed. This includes
verifying that all switches are installed in correct
locations and all wiring, pressure, and impulse lines
are properly connected.
3. Make sure components of the spark ignition system
are installed and functioning properly.
4. Make sure that the blower rotates in the correct
direction. If incorrect, then have a qualified electrician
rewire the blower to reverse its rotation.
5. Make sure all valves are installed in proper locations
and are properly oriented relative to the gas or air flow
direction.

Refractory Block Curing Schedule

The refractory block was cured at the factory up to a
temperature of 650°F (345°C). Final curing should be
done after installation.
The recommended curing schedule is:
• Ambient to 600°F (315°C) at 100°F (55°C) per hour.
• 600°F (315°C) to 1000°F (540°C) at 25°F (14°C) per
hour. Hold the refractory block at 1000°F (540°C) for
12 hours.
• Cool or raise the operating temperature at a rate of
100°F (55°C) per hour.
