Intermittent Pilot Module
APPLICATION
These ignition modules provide ignition sequence, flame
monitoring, and safety shutoff for intermittent pilot central
furnaces and heating appliances. S8600 and S8660
models provide up to 1.0A pilot and 1.0A main valve
current rating. S8610 and S8670 models provide up to
1.0A pilot and 2.0A main valve current rating. Minimum
ambient temperature rating is -40° F (-40° C). Maximum
ambient rating is 175° F (79° C) for S8600, S8660 and
for S8610, S8670 used with 1.0A or less main valve.
Maximum ambient rating for S8610, S8670 used with 1.0
to 2.0A main valve is 165° F (74° C). See Table 1 for a
summary of other differences between models.

If established flame is lost, all models restart ignition trial.
BEFORE INSTALLATION
Intermittent pilot systems are used on a wide variety of
central heating equipment and on heating appliances
such as commercial cookers, agricultural equipment,
industrial heating equipment and pool heaters. Some of
these applications may make heavy demands on the
controls, either because of frequent cycling, or because
of moisture, corrosive chemicals, dust or excessive heat
in the environment. In these situations, special steps may
be required to prevent nuisance shutdowns and
premature control failure. These applications require
Honeywell Residential Division Engineering review;
contact your Honeywell Sales representative for
assistance.
