Ignition stops after the first spark
1. Loose ground connection at the valve
Figure 25
Check ground connection at the Valve and
tighten screw. See Figure 25.
No pilot flame but spark
1. No gas supply
Check the gas supply
2. Air in the pilot supply line
Purge the line or start ignition several
times
3. No spark and Pilot Burner
Check pilot setup, page 14. Check wiring
connections. Check for spark in location
along cable.
4. Valve
Replace Valve. Do not overtighten the
Thermocouple Interrupter.
5. Receiver
Replace Receiver and reprogram code
6. Thermocouple circuit wire incorrectly
Check polarity of the Thermocouple wires
Pilot is lit and sparking stops. Valve
shuts off after 10 to 60 seconds. Valve
does not operate manually:
NOTE: For manual operation turn the
Valve knob to the manual position and
hold the safety magnet open with a
pen for approximately 60 seconds (see
Figure 26).

1. Not enough voltage generated from the
Thermocouple or too much resistance in
the circuit.
NOTE: To find which part of the circuit
is causing the problem, a checklist for
each application can be prepared using
an Excel calculation available from Mertik
Maxitrol.
Possible parts causing excessive resis-
tance are: ON-OFF Switch, Temperature
Switches, Thermocurrent Connections,
Receiver.
Use a digital multimeter set in the mV
range and measure the voltage by con-
necting the test leads to the spade con-
nector. Spade connector is located on the
outer surface, directly beside the magnet
nut (see Figure 27). The available voltage
must be at least 5 mV. The manufacturer
must specify the drop time for the applica-
tion. The drop time can be measured after
the Thermocouple is heated.
Figure 27
2. Thermocouple
Replace Thermocouple
3. Low inlet pressure to Valve
Confirm sufficient inlet pressure to the
Valve. Adjust or replace inlet regulator if
necessary.
4. Valve
Replace Valve. Do not overtighten the
Thermocouple Interrupter
Frequent beeps for 3 seconds while
motor turns
1. Batteries (Receiver) are low
Replace the batteries in the Receiver
and/or Remote Handset (quality Alkaline
recommended).
WARNING
Do not use metal tools to remove bat-
teries. Doing so will render the Receiver
inoperable. See Figure 20.
