Question

Have bought my first motorhome. After trying to operate propex heater we discovered it has been removed...just wondered where to get a gas flow diagram to work out what is safe to use after capping gas pipe left from removal of heater...many thanks k

Answer

If you intend to fit a replacement Propex heater then it is simply a matter of installing the heater and connecting the gas (should be checked by a GAS Safe engineer).
The new heater will come with full installation instructions for flue pipes etc.
