FIGURE 6C - With 24 VAC DIRECT SPARK IGNITION (DSI) 2-STAGE CONTROLS (Option
AG2R on RIHV100, RIHVN150, and RIHVN200 only)
• Electrical supply: 24 VAC - 60 Hz or 50 Hz - 1 Phase.
• Maximum total heater current draw: 0.96 Amps.
• Total heater power consumed: 23.1 VA (23.1W).
• 3-wire field service required to 2-stage thermostat. 4-wire thermostat cable required from thermostat to heater.
• Field wiring use 18/4 [18 AWG (0.8mm2)/4-conductor] solid class 2 thermostat cable having a minimum
insulation temperature of 140°F (60°C) between thermostat and heater. Maximum length is 125 feet (38m).

NOTES:
•
Control is polarity sensitive.
•
Installer to provide and install #10 ring terminal required for ground service conductor to attach to green ground screw in
heater control box.
•
See Paragraphs 7.1 and 7.2 for detailed information on electrical supply and thermostatic control.
•
If any of the original wire as supplied with the appliance must be replaced, it must be replaced with wiring material having a
temperature rating of at least 302°F (150°C) and a minimum size of 16 AWG (1.0mm 2 ).
