i) assembly instructions flawed: too small and cluttered with very low-contrast monochrome pictures (Augenpulver).
ii) completeness of mounting material deficient: The number of nuts and bolts does not agree with the amounts required and specified in the assembly instructions. As some screws were missing, a visit to the nearest hardware store was required. In addition, metal parts are in the package that are not mentioned in the setup / manual and are also obviously not needed.
iii) construction itself: Well, for an experienced hobbyist rather no problem, however, is missing here may be one overwhelmed. A helper is absolutely necessary, but is recommended in the manual.
iv) fit the front door deficient: Here metalworking skills are needed to mold and adjust accurately.
v) connecting easily to the gas cylinder.
vi) It would be desirable that the gas flow in normal operation can be interrupted directly by the gas regulator, turn off the heater only by closing the gas bottle possible (unless the heater falls over, then the gas flow will automatically stop).
But as I said, when you're done, the spotlight brings joy.
