WARNING:
Operation outside specifications could result in failure of
the Fenwal product and other equipment with injury to
people and property.
High Voltage Cable
Fenwal Part Number 05-129608-624 Suppression Cable (or equivalent)
must be used for proper operation of control.

between V1 & V2)
5. Flame OK during TFI, A. Bad electrode
no flame sense after TFI B. Bad S1 or HV wire
C. Poor ground at burner
D. Poor flame (check flame current)
FLAME SENSOR CURRENT CHECK
Series 35-60
SERVICE CHECKS
Flame current is the current which passes through the flame from
the sensor to ground. The minimum flame current necessary to
keep the system from lockout is .7 microamps. To measure flame
current, connect an analog DC microammeter to the FC-FC+
terminals per figure. Meter should read .7 uA or higher. If the
meter reads below “0” on scale, meter leads are reversed.
Disconnect power and reconnect meter leads for proper polarity.
PROPER ELECTRODE LOCATION
Proper location of the electrode assembly is important for optimum
system performance. It is recommended that electrode assembly be
mounted temporarily using clamps or other suitable means so that
the system can be checked before permanently mounting the
assembly. The electrode assembly should be located so that the
tips are inside the flame envelope and about 1/2 inch (1 cm) above
the base of the flame. See Figure 3.
CAUTIONS:
1. Ceramic insulators should not be in or close to the flame.
2. Electrode assemblies should not be adjusted or disassembled.
Electrodes should have a gap spacing of 0.125± 0.031 in
(3.12± 0.81 mm). If this spacing is not correct, the assembly must
be replaced. Electrodes are NOT field adjustable.
3. Exceeding the temperature limits can cause nuisance lockouts
and premature electrode failure.
4. Electrodes must be placed where they could not be
exposed to the appliance user in normal operation.
