A sound preventative maintenance program, carried out by qualified individuals, will
greatly increase equipment reliability and productivity. Frequency of maintenance
checks should reflect the duty cycle of the heating equipment and conditions such as
dirt and temperature. Any maintenance program should include at least the following
steps:
Check the burner's high and low fire air and gas settings.
Examine and, if necessary, clean or replace air and gas filter elements.
Check all piping connections for leaks.
Check the ability of the flame supervision system to function properly by simulating
system failures:
Simulate burner flameout by manually shutting off the gas.
Trip out pressure switches and other limit interlocks.
Try to light the burner before the purge and other timers have finished their cycles.
If simulated limit or flame failures do not shut down the fuel system within an accept-
ably short period of time, immediately take the equipment out of service and correct
the problem.
Leak test automatic and manual reset fuel valves per insurance procedures.
Check all bolts and screws for tightness.
Check the area around the burner mounting flange for signs of overheating. Gasket re-
placement may be necessary.
Check the interior of the burner and immersion tube for water accumulation. Small
amounts of water may collect due to condensation of combustion products. Large
amounts of water may be a sign of tube leakage.
Ignition plugs and flame rods wear out over long periods of normal burner operation.
Eclipse recommends that the user keep at least one of each in stock at all times to
prevent nuisance shutdowns. See Figure 5 for plug and rod numbers.
The flame rod electrode lengths listed in Figure 5 extend the rod about 1/2" (13 mm)
into the flame. Be certain that the flame rod is not grounded.
The ignition plug specified has an adjustable electrode length. To install the plug,
loosen the electrode and thread the plug into the burner. Push the electrode toward
the burner centerline until it stops. Then pull the electrode back 3/32" (2 mm). Tighten
the electrode in this position.
