202 SteamCraft 10 Service Manual, Chapter 8
We recommend mounting the module with the terminals
down to protect them from dripping water and dust. It can
also be mounted with the terminals on either side. DO NOT
MOUNT with terminals pointing up Fasten securely with
tool No. 6-32 machine or No. 8 sheetmetal screws.
MOUNT THE SYSTEM CONTROLS
Mount any required controls, such as the gas control,
spark igniter, flame sensor, thermostat, limit and transformer
according to manufacturer's instructions.
WIRE THE SYSTEM
1. Check the wiring diagram furnished by the appli-
ance manufacturer, if available, for circuits differing
from the wiring hookups shown. Carefully follow any
special instructions affecting the general procedures
outlined below.
2. Disconnect the power supply before making wiring
connections to prevent electrical shock or equipment
damage.
1. As shown in the wiring diagrams, a common ground is
required on:
a. The pilot burner mounting bracket, and
b. The GND(Burner) terminal on the ignition
module. Failure to user 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
module requires at least 0.2 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 multiply by 24 to determine the total VA
requirement of these components. Add this total to 4.8
VA (for the ignition module). The result is the minimum
transformer VA rating. Use a Class II transformer if
replacement is required.
Connect Ignition Cable
Use Honeywell ignition cable or construct an ignitio n
cable that conforms to suitable national standards such as
Underwriters Laboratories Inc. See Tables 2 and 3.

Cable must be no longer than 36 in. (0.9m). To construct a
cable, fit one end of ignition cable with ¼ in. diameter Rajah
connector receptacle and the other with a ¼ in. female quick
connect. Protect both ends with insulated boots.
NOTE: The cable must not run in continuous contact with a
metal surface or spark voltage will be greatly reduced. Use
ceramic or plastic standoff insulators as required.
To install:
1. Connect one end of the cable to the male quick
connect SPARK terminal on the ignition 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
The D80B Vent Damper can be used with all
ignition modules, although the Molex plug provided on some
modules simplifies wiring connections when used with the
D80D Plug-In Vent Damper. Once a module with vent
damper plug has powered a vent damper circuit, it cannot be
used in a gas system without a vent damper. A non-
replaceable fuse in the module blows on initial power-up.
Once this fuse has blown the module won't work unless the
vent damper is connected.
To connect the plug-in model to D80D:
1. Remove th plug from the terminal strip on the
ignition module case and discard.
2. Using the wiring harness supplied, insert the
matching pin plug into receptacle on case and other
end to vent damper.
To connect the D80B, follow the wiring diagrams supplied
with the vent damper or see Fig. 7 for typical connections.
Connect Ignition Module
1. Connect remaining system components to the
ignition module terminals as shown in the
appropriate wiring diagram, Figs. 1 to 10.
•
Fig. 1 is a basic circuit for a heating only
atmospheric burner with S8600F, H, M;
S8610F, H; S8660D or S8670D.
•
Fig. 2 shows S8600F, H, M; S8610F, H with
vent damper plug in a heating only atmospheric
burner system with D80D vent damper. Never
use a vent damper in an LP gas system or in a
fan-assisted combustion system.
•
Figs. 3 and 4 show S8600A, B; S8610A, B with
separate sensor and ingitor, with and without
the D80D vent damper.
•
Figs. 5-10 shown S8600F, H, M; S8610F, H;
S8660D; and S8670D in a variety of systems,
with alternate connections for modules with
vent damper plug. Remember, however, t hat a
vent damper should not be used in a fan
assisted combustion system or an LP gas
system and that the vent damper plug must not
be removed except to connect the module to a
D80D with the plug-in cable. S8600A, B;
S8610A, B can be substituted in these drawings
by simply connecting the ignitor and sensor as
shown in Figs. 3 and 4.
2. Refer to heating appliance manufacturer's
instructions for wiring auxiliary controls.
3. Adjust thermostat heat anticipator to match system
current draw. The current draw equals the total
current required for the ignition module (0.2 A) olus
the gas control and any other auxiliary equipment in
the control circuit.
Connect Gas Control
Use No. 18 gauge solid or stranded wire. Use ¼ in.
F
female quick connects for module connections. Connect to
302
gas control terminals appropriate to the gas control.
