Operation continued
This manual reset button can be located on the
ignitor board or remotely on a control panel.
(Consult factory for remove mounting agency
approvals). Should the flame not be established
during the trial for ignition period, the system will
lock-out. Should flame-out occur any time during
the duty cycle, the system will retry for ignition,
one time, and then lock-out. The manual reset
button will then trip within several seconds. After 5
second, depress the reset button to reset the control
module.
Flame Sensing
The Series 05-14 ignitor is designed to operate with
a single electrode assembly, which provides the
spark and senses the presence of flame. See Figure
3 Aor B. Remote sensing models, however, allow
for the flame sensing function to be separated from
the spark function and located remotely. See Figure
3C or D. Utilization of remote sensing insures
flame propagation across and entire burner pack.
Electrode Application
(Burner Manufacturer only)
1. Manually ignite burner flame to observe
flame characteristics.
2. Temporarily mount electrode directly over
burner parts in blue part of flame pattern.
Electrode tips should be 1/4 to 1/2-inch
above parts. Mount electrodes so that both
tips are immersed approximately 1/2-inch
into the flame with 1/8-inch spark gap
directly over a port. See Figure 1.
Figure 1
3. Connect the electrode lead wires to the
control module. See Figure 3. Make
certain that the remaining system wiring is
complete.
4. With the gas supply m;anually shut off,
cycle the thermostat to operate the control
module. Insure that steady sparking occurs
at electrode tips. Sparking should not
occur elsewhere.
5. Cycle thermostat to OFF position or
depress reset button and manually restore
gas supply.
6. Cycle thermostat on ON position noting
that sparking occurs immediately and that
the flame is established within a period of
no more than four seconds. Once the
flame is established, sparking will cease.
7. If ignition is achieved within four seconds
and sparking terminates immediately after
flame is established, you have a
functionaaly sound installation. However,
should these requisites not be met, consult
the "System Checks" section on page 4 for
remedial recommendations.
NOTE: Electrode assemblies are presision components and
should not be adjusted or disassembled. Electrodes should
have a gap spacing of 0.125"=0.031". If this spacing is not
correct, return the electrode assembly to the factory for
replacement. Electrodes are NOT field adjustable.
