Diesel fuel filter replacement, two sizes

[Perfection]

I bought an original Toyota filter for my Verso Diesel 2.0 2010 model. The dealer sold me a larger than the original one. 

I fitted the larger one, but means I have to fit it without the heat shield. It's all running fine...

Could someone confirm that if your car has a heat shield fitted or not please?

I am just wondering if i am putting the car at fire risk by doing what I have done, i.e. without fitting the heat shield.

There seems to be plenty of gaps and space between the engine and the filter thought.
