Operating Instructions
The blower kit features a simple switch for controlling its operation, allowing for both manual and automatic modes to optimize heat distribution.
Blower Modes
- MAN (Manual) Mode: In this setting, the blower will run continuously, regardless of the heater's temperature. This is useful for constant air circulation.
- AUTO (Automatic) Mode: When set to AUTO, the blower will activate automatically when the heater reaches a certain temperature, as detected by its integrated thermal couple. It will then turn off once the heater cools down. This mode provides efficient operation by only circulating air when heat is being produced.
