Step 5: Operating Checks - Eclipse Linnox SP CCS-LS Installation Manual

Step 5:
Operating checks
9. If the setting of adjustment valve (7) has been changed, repeat
step 6 and 7 again to check and re-adjust the low fire setting.
Caution:
Adjusting the burner too gas-rich will shorten the life time of
the burner elements and flame shields. Therefore, have a
qualified Eclipse engineer adjust and regularly check the
burner settings.
1. Simulate a flame out condition by closing the manual inlet ball
valve. Run the ignition cycle again.
2. Check high gas pressure switch for correct operation by
reducing the set point until it trips. The burner must be at
high fire. Re-set to the original setting and run the ignition
cycle again.
3. Check the combustion air pressure switch for correct
operation by increasing the set point until it trips. Re-set to
the original setting and run the ignition cycle again.
4. Measure and record the gas and air differential pressure and
flame signal at low and high fire for future reference.
Danger:
If simulated limits or simulated flame failures do
not shut down the fuel system within the required
response time, immediately correct the problem
before proceeding.
Caution:
Do not turn the combustion air blower off until the chamber
temperature is below 250°F (120°C). This will prevent hot
gases from flowing back through the burner and the blower
and causing damage to the burner.
