Installation and NZ gas safety
This is a fixed LPG appliance. In New Zealand, gasfitting work on caravans and motorhomes must be carried out and certified by an authorised person. Your installer must confirm heater sizing, ventilation, flue position, service access, electrical supply, water-system pressure and compliance for your particular vehicle.
Frequently asked questions
Is this the complete installation kit?
It includes the heater package and the core flue, water and warm-air outlet components listed above. Vehicle layouts vary, so 65 mm warm-air ducting and other installation-specific parts may still be required.
Does it include the iNet X Panel?
Yes. Truma part 33814-20 includes the iNet X Panel, room-temperature sensor, 6 m control cable and fixing parts.
Can it heat water without heating the cabin?
Yes. In summer mode, the Combi 6E can heat water without running the space-heating function.
Can I install it myself?
The fixed LPG installation and certification must be handled by an appropriately authorised New Zealand gasfitter. Electrical and other work should also be completed by suitably qualified people where required.
