F3600 mounting question

We’re moving the Fox F3600 invertor into the loft from an outside building. One installer wants to mount it on a wooden board fixed to the rafters and says they have installed hundreds this way. This will slightly slope the inverter back 10-15 degrees from being vertical. Another installer said that cannot be done, and that the inverter must be perfectly vertical and mounted onto brick or a fireproof board.

The Fox manual shows it mounted on an external(?) brick wall and says, ‘The slope of the wall should be within ±5°’.

I live in a terraced house, so I have no wall to mount it on. Can anyone clarify if I can mount it on wood in the loft with a slight slope back, or will it be a fire risk?
