The meeting was delayed for around half an hour but Ryan Fisher and Morten Risager still missed their early races.
Overall, it proved to be a night to forget for the Devils, who lost 64-28, with Jack Holder providing their only race win of the evening when he beat Justin Sedgmen in heat five.
The Devils will hope for better fortune on Sunday evening when they face another away fixture with a league match at Peterborough.
