I suspect the heating step uses gas burners. The tip on these will be designed for a certain heat release for a specified gas composition. If the design is for natural gas e.g methane and instead a tank supply (typically propane) was hooked up the burners may have Flame length issues as the heat of combustion from propane is higher per unit of volume then methane. Meaning a lower gas pressure would be used for the same heat release, and thus a shorter flame leading to heat distribution issues. However, that is just my speculation and it could simply be the tank hooked up was simply sized wrong and they can't get the burner to stay on properly. Also speculation.
Just remember they likely grabbed this as an "off the shelf" solution when the gas supply kept being delayed. When you plan on using mains gas for heating long term why would you spend any real time or money on a short term solution? I don't think you would and I imagine that's where they got too.
