you have to include a user distance-restraint, the concerning chapter in the manual about these restraints and the parameters used is named "2.5 Calculation of spatial restraints".
There is also the FAQ at http://salilab.org/modeller/FAQ.html, open it and look for "I want to add my own restraints".
This is an example (to be inserted in your .top file):
... [rest of your .top-file...] CALL ROUTINE = 'model' SUBROUTINE ROUTINE = 'special_restraints' SET ATOM_IDS = 'CA:25' 'CA:187' ADD_RESTRAINT RESTRAINT_PARAMETERS = 3 1 1 27 2 2 0 10.0 1.0 SET ADD_RESTRAINTS = off RETURN END_SUBROUTINE
I hope this helps you getting started. Best wishes and happy modelling,
