S8610U UNIVERSAL INTERMITTENT PILOT GAS IGNITION CONTROL

11.
Applicable only to warm air heating appliances.
Check both limit controller and fan controller for
proper operation. Limit controller operation can be
checked by temporarily disconnecting the electrical
supply to the blower motor and determining that the
limit control acts to shut off the main burner gas.
12.
Applicable only to boilers:
a. Determine that the circulating water pumps are
in operating condition.
b. Test low water cutoffs, automatic feed controls,
pressure and temperature limit controls and
relief valves in accordance with the manufac-
turer’s recommendations and instructions to
determine they are in operating condition.
Remove Old Ignition Control Module
Disconnect power supply before doing any work on the
unit. Disconnect and tag the wires from the old module.
Remove the old module from its mounting location.
Mount New Ignition Control Module
The recommended mounting for the S8610U ignition
control module is the same location as the old control
module. Otherwise, select a location close enough to the
burner to allow a short (3 ft. [0.9 m] maximum), direct
cable route to the pilot burner. Ambient temperature at the
control module must be within the range listed in the
“Specifications” on page 3.
Mount the ignition control module with the terminals down
to protect them from dripping water and dust. The control
module can also be mounted with the terminals on either
side. Do not mount with the terminals pointing up. Fig. 1
on page 6 illustrates the incorrect mounting position.
When it is necessary to drill new mounting holes, use the
S8610U as a template to mark the mounting hole pattern.
Drill new holes, as required. Fasten securely with four —
No. 6-32 machine screws, or No. 8 sheet metal screws, or
8-18 x 5/8 Pan Head tapping screws.
Location
The mounting location must provide:
— Good, clear access to the field wiring terminals.
— Operating ambient temperatures between
-40°F (-40°C) and 165°F (74°C).
— Relative humidity below 95% non condensing.
— Protection from water, steam or corrosive chemicals
that are used to clean the appliance.
— Protection from dripping water, such as from an
overfilled humidifier or from condensation.
— Protection from dust or grease accumulation.
IMPORTANT
Do not mount with terminals facing up.

Wire the System
CAUTION
Equipment Damage Hazard.
Disconnect power supply before beginning wiring
or making wiring connections to prevent electrical
shock or equipment damage.
All wiring must comply with local codes and ordinances.
Refer to Fig. 2 and Table 9 on page 11 for typical
connections.
IMPORTANT
1. As shown in the wiring diagrams, a common
ground is required on:
The pilot burner mounting bracket,
and
the GND
(BURNER) terminal on the ignition control mod-
ule. Failure to use the GND (BURNER) terminal
may result in intermittent loss of spark and/or
loss of flame current sensitivity.
2. Make sure the transformer has adequate VA.
The
ignition control module
requires at least
0.1 A at 24 Vac. Add the current draws of all
other devices in the control circuit, including the
pilot and main valves in the gas control, and mul-
tiply by 24 to determine the total VA requirement
of these components. Add this total to 2.4 VA (for
the
ignition control module
). The result is the
minimum transformer VA rating. Use a Class II
transformer if replacement is required.
Connect Vent Damper (Optional)
If the ignition control module is to be used with a damper
connected to the module’s integral damper connector in
an atmospheric appliance, perform the following to
connect it to the module:
IMPORTANT
After the initial power-up, the ignition control
module senses the presence of the vent damper
connection. If the vent damper is connected, the
ignition control module permanently configures
itself to operate
only
with the damper con-
nected.
Once an ignition control module powers up with
a vent damper connected, the module will not
function without a vent damper being connected.
