Eclipse ThermJet Self-Recuperative, V5, Installation Guide 208, 2/4/2013
NOTE:
The inlet gas pressure to the ratio regulator must
be a minimum of 5" w.c. (12.5 mbar) higher than the
impulse line pressure at high fire condition.
Step 9: Spark Rod Cooling Option
If applicable, connect flex hose to air cooling connections
as shown in Figure 3.13.

Checklist After Installation
To verify the system was properly installed, perform the
following checks:
1. Be sure there are no leaks in the gas lines.
2. Be sure all the components contained in the flame
monitoring and control system are properly installed.
This includes verifying that:
• all the switches are installed in the correct locations.
• all wiring, pressure, and impulse lines are properly
connected.
3. Be sure all components of the spark ignition system
are installed and functioning properly.
4. Be sure the blower rotates in the proper direction. If
the rotation is incorrect, have a qualified electrician
rewire the blower to rotate in the proper direction.
5. Be sure all valves are installed in the proper location
and correctly oriented relative to the flow direction.
Prepare for Adjustment
After installation of the burner system components is
complete, the following steps should be followed in order
to prepare for adjustment:
1. Set the air pressure switch so that it drops out at 4"
w.c. (10 mbar) below the pressure rating of the blower.
2. Set the low gas pressure switch at 4" w.c. (10 mbar)
below the gas pressure measured at the inlet to the
main gas valve train.
3. Set the high gas pressure switch so that it comes on
at 4" w.c. (10 mbar) above the gas pressure
measured at the inlet to the main gas valve train.
4. Close all the burner gas cocks.
5. Try to light a burner before the purge and other timers
have finished their cycles. Make sure that the flame
monitoring system indicates a flame failure.
6. Trip out pressure switches and other limit interlocks.
make sure that the main gas valve train closes.

If simulated limits or simulated flame failures do
not shut down the fuel system within the required
failure response time, immediately correct the
problem before proceeding.
