14. Inspect the condition of the appliance mounting
plate and burner mounting fl ange gaskets and
replace any damaged materials. See Figure 6.
15. Inspect all burner control wiring and the burner
control panel for damaged insulation and loose
terminals/connections.
16. Verify that the source voltage to the burner and
control panel is within 10% of the burner rating
as listed on the nameplate. (Figure 1)
○ Appliance – (Follow appliance manufacturer's
service procedures. The following steps are
emphasized because they relate to burner operation)
1. Check the condition of the combustion chamber
refractory, the front-plate insulation, and all
gaskets and seals. Repair or replace as necessary
2. Insure that the fl ue passages, fl ue vent pipes,
and chimney fl ues are clean and unobstructed.
3. Check barometric damper or draft hood for
proper operation.
4. Inspect boiler sections and system load piping
for possible leaks. Make all necessary repairs.
5. Check all operating and safety controls on the
boiler for proper installation and operation.
6. Perform all maintenance and tests according to
the burner control manufacturer's instructions
(limits, controllers, low water cutoff, relief valves,
feed valves, etc.)
○ Gas supply piping:
Inspect all piping for leakage and proper installation.
Perform necessary repairs to comply with all codes.
○ Installation area:
1. Insure that there are no combustible materials,
fl ammable liquids or vapors in the vicinity of the
heating appliance.
2. Verify that the combustion air supply is
functioning properly, adequately sized, clean,
and properly lubricated.
CG10 Burner Manual
Section: Maintenance and Service
○ Adjust the burner for proper combustion:
Follow the guidelines under "Start the Burner" to set
the combustion levels using test instruments.
○ Flame safeguard:
Follow the control manufacturer's instructions and
verify that the control is functioning to specifi cations.
See Page 13 for typical sequence of operation and
Items 8 through 10 on Page 20 for control system
checks.
○ Manual shutdown for long periods:
1. Close all gas valves in the gas supply piping
system.
2. Turn off all electrical power to the burner.
3. Protect the burner and controls from moisture
and dirt.
○ Ignition Reliability
1. Examine ignition electrode inslators for cracks.
2. Examine ignition wires for worn insulation.
3. Examine ignition electrodes for wear.
4. Check ignition transformer functionality.
5. Verify that the head is centered in the airtube and
that the head is not damaged.
6. Check inlet pressure to the gas train SSOVs.
7. Verify maximum recommended pipe lenghts
used in gas trains (Figure 8)
8. Verify low fi re light-off rate (Table 2)
