Timberline support FAQ

Common questions about manuals, registration, and support for this brand.

  • What does Error Code 13 mean on my Timberline heater?

    Error Code 13 indicates insufficient fuel level causing ignition failure. This often occurs when the vehicle fuel tank is below 1/4 full. To resolve, ensure you have fuel, clear the error message, and restart the burner to prime the pump.

  • Can I use the electric element and diesel burner at the same time?

    Yes, the Timberline system is designed to use both the burner and electric element simultaneously. This is recommended when plugged into shore power to provide faster heat-up times and consistent hot water.

  • How do I fill the Timberline system with antifreeze?

    The system requires a mixture of water and antifreeze (typically 60/40). Check the antifreeze level in the Diagnostics page of the touch panel; it should be between level 4 and 6. Refer to your specific manual for the filling procedure via the expansion tank.

  • What is Storage Mode?

    Storage Mode keeps your van from freezing if parked in cold temperatures. When activated, the system locks the heater and electric element on to maintain a safe interior temperature. Do not use this mode if the vehicle is parked inside a building due to exhaust fumes.
