The following instructions do not supersede the local code.

WARNING: USE WIRES SUITABLE FOR 75O C (167 O F) ONLY.
*(With all reserves on the minimum combustion air to be increased depending on the type and quality of the combustible).
3.6THERMOSTAT
The thermostat must be installed on an inside wall in a location where it is not likely to be affected by the draft coming from an air outlet. It must be installed at a minimum of 55 inches above the floor.
3.7FAN CONTROL
The fan control setting may vary depending on the type of installation; the “fan OFF” temperature is preset at 110o F and the “fan ON” at 150° F at the factory. This setting should provide a proper operation for most installations.
For a prolonged operation of the blower, it is preferable that the “fan OFF” setting be low enough. But a “fan OFF” setting too low will cause undesirable cold air circulation. To modify the setting, move the tab on the temperature dial of the fan limit control at the desired position.
The adjustment of all controls must be performed by a qualified technician. The controls setting and the blower speed must conform to the recommendations of the “Warm Air Heating and Air Conditioning National Association”. To obtain a continuous air circulation during summer, move the manual switch ON.
