Built-in oven touching gas pipe to hob

We just bought a new oven to replace a faulty one, both Zanussi. The new oven is somewhat deeper than the old one so when it is pushed into place it is touching the gas pipe that feeds the hob. It is not putting much pressure on the pipe as it fits flush to the carcass without any effort. However it is touching it at the top where there is an elbow joint on the gas pipe to go into the hob and also at two points along the pipe where there is a join and therefore two nuts which protrude a bit. I was able to verify this by putting some lumps of blu-tack on the pipe at these points.

I’m just wondering if this is a problem or if it is safe to install it like this. I doubt there is much heat generated by the rear of the oven because there are a lot of wires and cables within the oven casing which would get damaged. There also seems to be a layer of insulation at the back of the oven. Am I right in assuming the heat won’t be a problem? I’m also wondering if there might be some vibration from the fan (oven, not the cooling one) which could potentially affect the gas pipe over time and perhaps cause a leak or whatever? I’ll attach a photo if I can to illustrate the position of the pipe.

Thanks for any help or advice!
