•Place a jumper across cad cell terminals.

•Follow procedure to turn on burner.

Burner must not start, indicator light turns on and control remains in Idle Mode.

•Remove jumper.

iii.Simulate Ignition or Flame Failure:

•Follow procedure to turn on burner.

•Close hand valve in oil supply line.

•Failure occurs, device enters Recycle

Mode. Indicator light flashes at ¼ Hz rate

2 seconds on, 2 seconds off).

•Device tries to restart system after approximately 60 seconds.

•After third Recycle Mode trial, safety switch locks out within safety switch timing indicated on label and control enters Restricted Mode. Indicator light flashes at 1 Hz rate (½ second on, ½ second off). Ignition and motor stop and oil valves closes.

iv.Cad Cell Check: See Figure 26.

Figure 26: Cad Cell Location

•Perform cad cell resistance check as outlined in control feature. If resistance is below 1600 OHMS and burner runs beyond safety cut-out time, cad cell is good.

•If safety switch shuts down burner and resistance is above 1600 OHMS, open line switch to boiler. Access cad cell under ignitor, clean face of cad cell and see that cell is securely in socket. Check gasket around perimeter of ignitor lid for proper seal. If gasket is missing or damaged, replace gasket. Room light can effect cad cell resistance. Reset safety switch.

•Close line switch to boiler. If burner starts and runs beyond safety switch cut-off time, cell is good. If not, install new cell.

v.Power Failure Check: After Flame is established, turn the power off to the control/ burner. The burner should shut down safely.

When power is restored a normal ignition sequence should be started.

3.WARNING — Check Pressure Limit Control

—Jumper Thermostat Terminals. Allow burner to operate until shut-down by limit. Installation is not considered complete until this check has been made.

WARNING

Jumper must be removed after this check.

4.Check low water cut off control with water level at normal water line (see Figure 1). Raise thermostat setting to allow burner to operate. Open boiler drain to allow water level to drop to bottom of sight glass until burner operation is shut-down by low water cut-off.

Close boiler drain and refill to normal water line. Burner should automatically restart during fill.

Lower thermostat setting.

5.Check operating control on boiler equipped with tankless heaters. With burner off, draw hot water until burner starts, then turn off hot water and check burner shut-down.

J.IF CONTROLS DO NOT MEET REQUIREMENTS outlined in Paragraph I., replace control and repeat checkout procedures.
