NF Air And Water Combi Heater
Application
Heating and hot water in one: NF Combi heaters
NF Combi heaters combine two functions in one appliance. They warm the living area and heat water in the integrated stainless steel tank. Depending on the model, Combi heaters can be used in gas, electric, petrol, diesel or mixed mode.Combi D 6 E heats your vehicle(RV, CARAVAN) and heats water at the same time. Integrated electric heating elements reduce the heating time.

Gas Connection
The heater operating pressure must be in compliance with a 30 Mbar liquefied gas supply. When the gas pipe is cut off, clean the port flash and burrs.The paving of the pipe must make the heater easy to disassemble for maintenance work. Use high-pressure air to purge internal debris before installing the gas pipe. The turning radius of the gas pipe is not less than R50, and it is recommended to use elbow pipe to pass the joint of right angle.
The gas interface be truncated or bent. Before connecting to the heater, make sure that the gas line is free of dirt, shavings, etc. The gas system must comply with the technical, administrative, and legal regulations of the country. Anti-collision safety valve (optional) To ensure safety during driving, it is recommended to install a crash safety valve that must be installed after the liquefied gas tank regulator. when Impact, tilting, the anti-collision safety valve automatically cuts off the gas line.
