Blown air heater blows out

We have a Truma blown air heater system and I have to say that we are very happy with it. HOWEVER - whilst I fully acknowledge that the winds lately have been very strong, when the heater is cold, it is almost impossible to get it to light. It does light
but a strong gust seems to blow it out. Once the system has warmed up, it withstands the gusts.

According to the service history, the heater was serviced six months ago.

Is this behaviour normal?
