Choosing this Truma kit means you’re getting genuine parts designed to work together as a system.

• Ensure the heater is powered down and cool before starting any work. Follow TRUMA service guidance for your model to avoid damage.
• Inspect all connections and seals during reinstall to confirm airtightness and proper seating of the new tank and seals.
• Use the included ducting clips to secure air pathways, preserving efficient heat transfer and reducing noise or vibration.
• Schedule periodic checks as part of routine maintenance—replacing worn components before leaks occur helps sustain performance and energy efficiency.
