Ground Control System
The igniter, flame sensor and ignition module must
share a common ground with the main burner. Use thermo-
plastic insulated wire with a minimum rating of 105

REPLACING MODULE WITH TH-R, TH-W TERMINALS
On modules that do not have a vent damper plug, the
thermostat must be connected between the transformer
and the 24V terminal on the module. To change out a
module with TH-R, TH-W terminals:
module with TH-R, TH-W terminals:
1. Remove the wires from the 25V(2) and TH-R termi-
nals on the old module. Connect these two wires with a
solderless connector.
solderless connector.
2. Tag and remove the remaining wires from the old
module.
3. Remove the old module and mount the new one in the
same location.
4. Reconnect the remaining wires as shown in Table 4.
5. Increase the thermostat anticipator setting by 0.2 A.
