Modeller is a package for comparative modeling, so if you don't have a 
template,
it won't be able to generate a reasonable-looking model. You may be able 
to find
another template that aligns reasonably well with that range, for example by
using a more sensitive search for templates such as profile-profile.

If you can't find a template for residues 1-70, you have no option with 
Modeller
except to exclude those residues from your model sequence.
