• and
• at least one fluid line area for conveying fluid to and from the fuel-operated heater, the at least one fluid line area comprising:
• a combustion air line area for sending combustion air to a combustion air inlet of the fuel-operated heater;
• a heat transfer medium line area for sending heat transfer medium flowing in a heat transfer medium circuit of the vehicle through the carrier device and/or for sending heat transfer medium to and from the heat exchanger area of the fuel-operated heater;
• wherein the heat transfer medium line area comprises:
• a first line area with a first heat transfer medium circuit connection area arranged for being connected to the heat transfer medium circuit and with a first on-off valve connection area connected to the first connection of the on-off valve;
• a second line area with a second heat transfer medium circuit connection area arranged for being connected to the heat transfer medium circuit and with a second on-off valve connection area connected to the second connection of the on-off valve;
• a third line area with a third heat transfer medium circuit connection area arranged for being connected to the heat transfer medium circuit and with a third on-off valve connection area connected to the third connection of the on-off valve;
• a fourth line area with a first heat exchanger area connection area connected to the heat exchanger area and with a fourth on-off valve connection area connected to the fourth connection of the on-off valve by a flexible line connection;
• and
• a fifth line area with a second heat exchanger area connection area connected to the heat exchanger area and with a fourth heat transfer medium circuit connection area arranged for being connected to the heat transfer medium circuit.
