Starting the Heater
Once powered on, the heater will initiate a startup sequence. This typically involves a pre-heating phase before full heat output begins.
Adjusting Heat Output
The heater's power can be adjusted between 5-8 kW to suit your heating needs. Use the control panel, remote, or app to modify the heat level.
Highland Mode
For operation at high altitudes (up to 18,045 ft.), activate the highland mode. This feature automatically adjusts the heater's performance for optimal combustion and efficiency in thinner air.
