We purchased a 2020 R-23 and wanted to know where the Webasto heater is located. The manual says that it is below the helm seat however the diagram that accompanies that statement shows it on the port side near the port observers seat. We had a temporary issue where the heater wouldn't light off but thinking we were nearly out of fuel I opened the fuel cap and the heater worked. Wonder if there is a blockage in the tank venting. (If there is any venting that is)
