The »zu« before an infinitive is a signal word for an infinitive clause. You can always disconnect the infinitive clause with a comma.
A comma is required
when the infinitive clause is introduced with um, ohne, statt, anstatt, außer or als, e.g.:
Ich komme, um mich zu beschweren.
when the infinitive clause depends on a noun, e.g.:
Ich habe die Absicht, mich zu beschweren.
It is advisable to always set a comma to clarify the structure of a sentence.
