TROUBLESHOOTING

FINAL CHECKOUT

Before putting the burner into service, check out the

installation by using 

 Checkout procedures in the instruc-

tions for the appropriate flame safeguard control. After
completing the checkout, run the burner through at least one
complete cycle to verify proper operation.

Do not put the system into operation until all
Checkout tests in the instructions for the appropri-
ate flame safeguard control and any specified in the

burner installation instructions are satisfactorily

completed.

 

 

1. Be extremely careful while troubleshooting the

detector; line voltage is present on some of the

terminals on the wiring 

 or terminal strip

when power is on.

2. Open the master switch to disconnect power

before removing or installing the detector, there

may be more than one disconnect involved.

If you cannot obtain a satisfactory flame signal while

adjusting the sighting position of the detector, follow these

procedures. If you encounter other problems in the system,
refer to Troubleshooting in the instructions for the appropri-

ate flame safeguard control.

EQUIPMENT REQUIRED

1. 

300 

 scale.

2. Microammeter (Honeywell 

 or equivalent)

with 0 to 25 microampdc range.

3. 

 196146, or 117053

Meter Connector Plug or equivalent (required for some
meters).

4. A volt-ohm meter with a zero to 5 or 10 Vdc scale and

a sensitivity of 20,000 ohm/volt is suggested for 

control flame signal measurements. If the control has the

Keyboard Display Module option, flame voltage is displayed

on the module.

5. A one 

 meter with a zero to 5 or 10 Vdc

scale is recommended for 7800 SERIES control flame volt-

age measurements. If the control has the Keyboard Display

Module option, flame voltage is displayed on the module.

6. Replacement parts-see Specifications.

TROUBLESHOOTING PROCEDURES

Firstperfonn 

 Inspection. Then follow the

applicable procedures for either a low reading or a zero
reading on the flame signal meter. After reinstalling the

detector, recheck the meter reading. Adjust the position of the
detector to try to obtain the proper 

 signal. If the

procedures are completed and a satisfactory flame signal

cannot be obtained, replace the detector.

PRELIMINARY INSPECTION

1.

 the flame is properly adjusted and is not

too lean.

2. Checkfortheproperlinevoltage. Makesurethemaster

switch is closed, connections are correct, and power supply

is of the correct voltage and frequency.

3. Check the detector wiring for defects including:

. incorrect connections.

l 

wrong type or size of wire.

l 

deteriorated wire.

l 

open circuits.

l 

short circuits.

l 

leakage paths caused by moisture, soot, or dirt.

4. With the burner running, check the temperature at the

detector. If it exceeds 125” F 

 

add additional insulation between the wall of the
combustion chamber and the detector.
add a shield or screen to reflect radiated heat away
from the detector.
add cooling (refer to Sight Pipe Ventilation, see

Installation).

PROCEDURE FOR A LOW METER READING

1. Remove the detector and clean the focusing lens 

a soft, clean cloth.

2. If the focusing lens is broken or damaged, or if it is

coated with a substance that cannot be cleaned off, replace the

 Bushing (which includes the focusing lens).

3. Clean the inside of the sight pipe before reinstalling the

detector.

4. If the meter reading is still too low, replace the lead

sulfide cell (Fig. 8).

5. If the meter reading is still too low, replace the plug-in

amplifier.

6. If you still cannot obtain a proper flame signal, replace

the 

 Infrared Flame Detector.

PROCEDURE FOR A ZERO METER READING

1. Replace the lead sulfide cell (Fig. 8). Then recheck the

flame signal.

2. If there is still no flame signal, replace the plug-in

amplifier.

3. If you still cannot obtain a meter reading, replace the

entire 

 Infrared Flame Detector.
