American Flame: AF-LMF Series Valve Kits
Rev. 4-26-21 Page 8
MAINTENANCE OF YOUR AF-LMF SERIES VALVE KITS
Your system should be checked once a year (at start of heating season) for proper operation by a qualified serviceman.
Items to check: Valve operation, pilot operation, switch operation, damper operation, visual check of the burner and check
gas connections for any leaks.
TROUBLESHOOTING
1. When lighting pilot, ensure you wait at least 30 seconds to one minute for the thermocouple to heat up before
releasing the black control knob. See lighting instructions.
2. Check the connection from the pilot assembly to the gas valve. Follow the copper wire to the gas valve and ensure the
fitting is snug and not too tight. The connection should only be installed finger tight plus a quarter turn with a wrench.
See Fig. 15 for reference.
3. Over time the thermocouple can get dirty with a white or soot film. This can cause the pilot not to stay lit or light at all.
Clean off the thermocouple and wipe off dust and try again.
4. If pilot will not light at all, then replace thermocouple or the entire pilot assembly.
5. If pilot flame it too large, noisy, or too small, it can be adjusted with the pilot adjustment screw by removing the two
screws from the front cover of the valve box. See Fig 16.
PILOT WILL NOT STAY LIT
REMOTE WILL NOT LIGHT BURNER
1. Ensure the pilot is lit and the control knob is in the ON position. See Fig.14.
2. Ensure the transmitter is “LEARNED” to the receiver. See page 6 as reference.
3. Check the black slide switch on the receiver. The switch should be in the REMOTE position. See Fig. 13.
4. Check the (4) batteries in the receiver. The total voltage of all (4) batteries should not be less than 5.3 volts.
5. Check the transmitter battery/batteries; there should be a red LED light glow when pressing any button on the remote
control.
Note
: The 12-volt battery should be no less than 9 volts and ensure the batteries are not installed backwards.
