As per the Gets Hot special rule in the rulebook any blast weapons with the ability to reroll to hits also get to reroll failed Gets Hot. And as Preferred enemy confers a reroll on a 1 and a failed Gets hot is a roll of a 1 I'd say you get to reroll.
Also, OP find Pask's unit entry in the detailed rules section where it has all the bonuses he confers to Leman Russ variants. That's why the punisher has rending. It's around page 60 somewhere.
