Modcon venting inside an insulated wall: Acceptable?

We are swapping out an existing modcon boiler. The current system has PVC vent and air supply pipes which run up two stories within an insulated wall.

One of the plumbers who is quoting the job says we must reroute the pipes because "you can't run them through an insulated wall because the joints can fail."

Is this in fact the case? If so, is it best practice or local code?

    Never heard of that before. Ask your local code official.

    We've gone to using PPL on the vent piping of mod/cons just avoid the issues that come with high SW temps.
