S8701/S8702 Direct Spark
Ignition Controls
APPLICATION
S8701 and S8702 Direct Spark Ignition Controls are
designed for use in commercial cooking and other gas
heating applications which require direct ignition and flame
safety control of gas burners. S8701/S8702 controls are
used to ignite the main burner(s), sense the flame and
control the gas valve in these applications, see Table 1.

The S8701 is a single spark, single flame sense, direct
ignition control that is compatible with dual rod systems.
The S8702 is a dual spark, dual flame sense, direct
ignition control capable of igniting and sensing flame on
two separate gas burners that are fed by a single gas
valve. The S8702 is compatible with dual rod systems
only.

S8702 F and M models include an auto-reset from lockout after 1 hour.
Planning the Installation
WARNING
Fire or Explosion Hazard.
Can cause property damage, severe injury,
or death.
Follow these warnings exactly:
1.
Plan the installation as outlined below.
2.
Plan for frequent maintenance as described in
the Maintenance section.
Review the following conditions that can apply to your
specific installation and take the precautionary steps
suggested.
Frequent Cycling
This control is designed for use on commercial cooking
appliances that typically cycle 400 times a day, year round.
Perform a monthly checkout.
Water or Steam Cleaning
If a control gets wet, replace it. If the appliance is likely to
be cleaned with water or steam, protect (cover) the control
and wiring from water or steam flow. Mount the control
high enough above the floor so it does not get wet during
normal cleaning procedures.
High Humidity or Dripping Water
Dripping water can cause the control to fail. Never install
an appliance where water can drip on the control. In
addition, high ambient humidity can cause the control to
corrode and fail. If the appliance is in a humid atmosphere,
make sure air circulation around the control is adequate to
prevent condensation. Also, regularly check out the
system.
IMPORTANT
Always install a splash cover to protect the
control from water damage.
Corrosive Chemicals
Corrosive chemicals can attack the control, eventually
causing a failure. If chemicals are used for routine
cleaning, avoid contact with the control. Where chemicals
are suspended in air, as in some industrial or agricultural
applications, protect the control with an enclosure.
Dust or Grease Accumulation
Heavy accumulations of dust or grease can cause the
control to malfunction. Where dust or grease can be a
problem, provide covers for the control to limit contamina-
tion.
