POINTS FOR THE BOILER USER

Note.

  

In line with our current warranty policy we would ask that you check through the following guide to identify any

problems external to the boiler prior to requesting a service engineers visit.  Should the problem be found to be other than
with the appliance we reserve the right to levy a charge for the visit, or for any pre-arranged visit where access is not gained
by the engineer.
