BURNER MAINTENANCE INSTRUCTIONS
To service the burner system, clean both the blower and the burner. Remove the
blower(s) from the system and allow you to clean dust from the wheel. Remove
the four nuts from each burner assembly for cleaning. Removing and cleaning
one burner at a time eases reassembly. To dislodge particulate matter from the
burner surface matrix, use compressed air (100 psig [700 kPa] maximum).
Keep the air nozzle about 2" (50 mm) from the burner’s surface, blowing air
perpendicular to the burner surface while moving the nozzle back and forth
lengthwise. This dislodges particles trapped in the matrix, pushing them back
inside the burner. Avoid blowing air across the surface, which tends to have a
destructive effect on the burner surface. Allow particulate matter to fall from the
burner through the air/gas inlet. To assist in removing the particulate matter,
use a vacuum at the burner’s air/gas inlet.
IGNITOR AND FLAME SENSE ROD
The enhanced spark ignition and flame sensor rod, as well as their
supporting gaskets, should be replaced at the same time every 5 years. The
entire combustion assembly does not need to be removed to replace these
components.
1. Follow the shutdown procedure on Page 60.
2. Remove shroud.
3. Disconnect flame sensor wire, ignition wire and enhanced spark ignition
from gas line.
4. Remove the mounting nuts and pull the components free from the assembly.
5. Replace with the new components.
6. Reconnect flame sensor wire, ignition wire and enhanced spark ignition to
the gas line.
7. Replace shroud.
