There are 4 different types of fire puja according to the four actions: pacifying, increasing, controlling, and wrathful. The pacifying ritual is most commonly used to purify mistakes made during a close retreat, but is not limited to this of course. There is a generic structure that these pujas typically follow but some of the offerings, tormas, hearth design, and wording change based on which of the four actions is emphasized and who the Principal supramundane guest is. There is also a simple burning offering ritual called Vajradaka that requires either black sesame seeds or a mixture of black sesame seeds and mustard seeds (as is done when Vajradaka is performed by the Vajra Master during the Heruka body mandala Wang), is typically used for purification, and is consider one of the 9 Preliminaries or Ngondro in which 100,000 burning offerings are collected.
In order to perform any of these it is necessary to receive tantric initiation and complete a close retreat of numbers that is concluded with a pacifying fire puja. The reason for this is not only that they are tantric rituals, but these burning offerings are considered 'actions of the mandala' and it is not permitted to engage in actions of the mandala such as fire puja or self-initiation without first completing the requirements which come from Vajradhara.
In particular, to perform Dorje Shugden fire puja, it is necessary to complete a close retreat of Vajrabhairava including Vajrabhairava fire puja, receive the life entrustment initiation of Dorje Shugden, and complete a close retreat of Dorje Shugden. What I found intriguing is that the aspect of Dorje Shugden is a bit different from the usual aspect, which seems to be an uncommon quality of this Dharmapala when you consider the different aspects he has also appeared as throughout his history.
You do not have to be ordained, have a high position, or have a special title to accomplish these things. What is required is to have faith, receive initiation, complete a close retreat, strive to keep the vows and commitments, and become familiar with the rituals.
Does that answer your question?
