IMPORTANT
1. All wiring must comply with applicable local
electrical codes and ordinances.
2. When installing the hot surface igniter, the
leadwires should be kept as short as possible
and should not be allowed to rest against
grounded metal surfaces.
3. A common ground is required for the S93XX
and the main burner. The 24V "secondary"
plug internally grounds one side of the trans-
former. Any auxiliary controls or limits must
not be in the grounded leg. In addition, the
appliance should be earth-grounded.
4. Make sure the transformer has adequate VA.
The ignition module requires at least 0.2A at
24 Vac. Add the current draws of all other
devices in the control circuit, including the gas
control, and multiply by 24 to determine the
total VA requirements of these components.
Add this total to 5.0 VA (for the module). The
result is the minimum transformer VA rating.
Use a Class II transformer if replacement is
required.
5. Check that L1 (hot) and L2 (neutral) are wired
to the proper terminals.
Connect Ignition Cable (S936XBXXXX,
S938XBXXXX)
Use Honeywell ignition cable or construct an ignition
cable that conforms to suitable national standards,
such as Underwriters Laboratories Inc. See
Specifications section. To construct a cable, fit one
end (the module end) with 1/4 in. connector
receptacle and the other with a connector to match
the pilot assembly. Protect both ends with insulated
boots.
NOTE: Cable length must be 36 in. (0.9 m) or less.
The cable must not be in continuous contact
with a metal surface or spark voltage will be
greatly reduced. Use ceramic or plastic stand-
off insulators as required.
1. Connect one end of the cable to the male
quick-connect SPARK terminal on the module.
2. Connect the other end of the cable to the igniter
or igniter-sensor stud on the pilot
burner/igniter-sensor.
Connect Vent Damper (Vent Damper
Models)
A vent damper can be used with modules provided
with a vent damper plug connector. The Molex
provided simplifies wiring connections.
To connect the vent damper, follow the wiring
diagrams supplied with the vent damper for typical
connections.
Connect Remaining Module
Connectors
Connect remaining system components to the
ignition module terminals as shown in the appropriate
wiring diagrams, Fig. 4 to 6.
Connect Igniter (HSI Models)
Prepare wiring harness:
1. Use wire suitable for the temperatures near the
HSI igniter.
2. Use wire suitable for the voltage ratings of the
specific igniter.
3. Attach connector per Table 4, HSI Specific
Connectors.
Connect Gas Control
Use No. 18 AWG solid or stranded wire. Connect to gas
control terminals as shown in wiring diagrams, using
terminals appropriate to the gas control.
Ground Control System
The igniter, flame sensor and module must share a
common ground with the main burner. Use insulated
wire approved by a nationally recognized testing
organization rated for a minimum of 105°C (221°F)
for the ground wire; asbestos insulation is not
acceptable. If necessary, use a shield to protect the
wire from radiant heat generated by the burner.
The burner serves as the common grounding area. If
there is not a good metal-to-metal contact between
the burner and ground, run a lead from the burner to
ground.
NOTE: "Earth" ground is not required.
S937XB Hot Surface Ignition
Versions
These models provide operating control of a direct
ignition system using a hot surface igniter. Additional
components required to complete the system must be
ordered separately. They include:
• Dual Valve Combination Gas Control: Any direct
ignition gas control with 2.0A maximum main valve
rating. VR8205, VR845, VR854, VR8450, or VR8540
recommended.
• Hot Surface Igniter: Norton Model 201 or 271 or
equivalent.
NOTE: If an igniter other than Norton Model 201 or
271 is used, the igniter must meet the follow-
ing minimum specifications, required over
the life of the igniter:
1.
2.
®
plug
3.
Sensor: Separate sensor required. Honeywell Q354
recommended.
Igniter Wiring: Provide wiring harness to suit
application.
• Leadwires: No. 18 AWG, stranded copper with
105°C rated, 1/16 in. insulated wire approved by a
nationally recognized testing organization. If wire
has been damaged, contact appliance OEM for
appropriate replacement or repair directions.
• Terminals: Insulated. See Table 4 for HSI specific
connectors.
7
Igniter must reach 1000°C (1832°F) within
34 seconds with 102 Vac applied.
Igniter must maintain at least 500 meg-
ohms insulation resistance between the
igniter leadwires and the igniter mounting
bracket.
Igniter current draw at 132 Vac must not
exceed 5 A.
