RELAY KIT INSTALLATION FOR MULTIPLE HEATER CONTROL
• DO NOT use these multiple heater control options with a two-stage gas valve or a two-stage
thermostat.
• These instructions are designed to assist a qualified electrician in installing this multiple heater
control kit.
• All electrical wiring and connections, including electrical grounding, MUST be in accordance with
the National Electric Code ANSI/NFPA No. 70 (latest edition) or, in Canada, with the Canadian
Electrical Code, Part 1, CSA Standard C22.1. In addition, the installation must comply with local
ordinances and applicable gas company requirements.
• These relay kits are designed to permit the control of up to six heaters (one control unit and up to five additional non-
control units) with one single-stage thermostat or with a time clock and single or multiple single-stage thermostats.
For maximum safety, the multiple control is installed in the low voltage circuit. Interruption of the supply voltage
is not recommended.
• Refer to the installation manual provided with the heater for important safety information.
• Pay attention to all dangers, warnings, cautions, and notes highlighted in this manual. Safety markings should not
be ignored and are used frequently throughout to designate a degree or level of seriousness.
• Model/option/voltage applicability is listed in
