WARNING

Electrical Shock Hazard

Disconnect electrical and gas supply before servicing.

This appliance must be connected to a properly grounded electrical source.

Failure to follow these instructions can result in death or electrical shock.

codes in accordance with: United States: refer to National Electrical Code® NFPA 70 - latest revision; Canada: refer to Canadian Electrical Code CSA C22.1 Part I - latest revision.

9.1 Positioning Thermostats

A room thermostat should be mounted on a vibration-free wall or column at a height of approximately 5' (1.5 m) from the floor to measure the ambient temperature. It should be clear of both cold drafts and the direct path of warm air from the heater.

Avoid mounting thermostat on outside walls or in areas directly exposed to radiant heat or sunlight. Install wall tag in a visible location near thermostat See Page 5, Section 2.1 for wall tag details.

9.1.1 Fan Control

All heater models require constant 120 V/1Ø/ 60 Hz power supply. Check heater rating plate for electrical rating for proper circuit sizing. For servicing, a disconnect switch of proper electrical rating should be installed in the vicinity of the heater.

All heaters are equipped with thermostat connections suitable to power a 24 V thermostat. Heater must be wired and electrically grounded in accordance with local codes. In the absence of local

The heater’s axial fan can be used during the off- season for air circulation. A low-voltage programmable thermostat with a fan switch (P/N 90425400) must be See Page 23, Section 9.2. used. For thermostat connection details. For the use of multiple heaters on one thermostat, See Page 24, Section 9.3 through Page 25, Section 9.4
