Fri-2 Motor Sich. Snizhansky machine-building plant, an updated version. The change is that the locking screw of the steam generator is between the tank and the comfort. Year of issue 2006.
So the valve is now located between the fuel tank pickup tube and the generator, where before (as on the PT-3) it was located just before the generator tip (jet). Safer. Shuts off the fuel at source, which if the generator were to split or develop a leak it couldn’t. The Coleman 501 had a similar fault, which made it unsafe to the extent of being withdrawn from sale.
Ви цілком правоте. Щоправда, в Україні ніхто не вийде з виробничої моделі Пт-3. Тому що Україна не США, а Мотор Січ не Коулмен О (You are right. True, in Ukraine nobody will get out of production model Пт-3. Because Ukraine is not the US, and Motor Sich is not Coleman)
@Andi It wasn’t just the location of the valve on the Coleman but a chronic thermal runaway (overheating) due to the design. My Motor Sich PT-3 doesn’t do that and the generator is very robust, so I don’t regard it as unsafe, personally.
If you take Пт-2 early years of production or even better OIB-2С (photo 'is on the forum), then the system and the layout are on the edge of security
