In Hinduism
Purana and Itihasa (epic history)
Source: archive.org: Shiva Purana - English TranslationSivāgni (सिवाग्नि) refers to the “Śiva fire”, according to the Śivapurāṇa 1.18. Accordingly, “[...] all non-ritualists shall worship the subtle Liṅga. In the place of floral offerings they shall use sacred ashes (bhasma) for adoration and food. They shall keep the Liṅga after worship on their head for ever. The ash is of three types, derived from Ordinary fire, Vedic fire and Śiva fire (śivāgni). [...] Bilva twigs shall be burnt repeating the Ātma mantra of Aghora. This fire is called Sivāgni. The ashes resulting therefrom are called Śivāgnija. The dung of a cow, preferably of Kapilā cow, shall be burnt first and then the twigs of Śamī, Aśvattha, Palāsa, Vaṭa, Āragvādha or Bilva shall be burnt. The ash resulting therefrom is also Śivāgnija. Or the twigs shall be burnt in Darbha fire repeating Śiva mantra. After straining the ashes with cloth (the fire powder) shall be put in a new pot”.

The Purana (पुराण, purāṇas) refers to Sanskrit literature preserving ancient India’s vast cultural history, including historical legends, religious ceremonies, various arts and sciences. The eighteen mahapuranas total over 400,000 shlokas (metrical couplets) and date to at least several centuries BCE.
Shaivism (Shaiva philosophy)
Source: Shodhganga: Temple management in the ĀgamasŚivāgni (शिवाग्नि) refers to the “fire in the kuṇḍa” as described in the Śaivāgamas while explaining the “continuity of nityapūjā”.—The fire in the kuṇḍa is śivāgni, which also called śaiva and is to be used in all temple worship. Also, śivāgni will not give results if the kuṇḍasaṃskāra is not performed. Using aśaivāgni or fire that is not śaivāgni, causes disease in the kingdom. If the rakṣāgni goes out, the Yajamāna’s life is in peril and the Ācārya must perform the japa prescribed as prāyaścitta.
Source: Brill: Śaivism and the Tantric TraditionsŚivāgni (शिवाग्नि) refers to “(veneration of) Śiva and the fire”, according to the 9th-century Sarvajñānottaratantra chapter 18.—Accordingly, “Next, I shall teach the best observance among observances, which is known as the Śiva-vrata and which is revered by Asuras and Gods alike. Pure pale ash [should be used, and] white dress and unguents; he should wear a white sacred thread and be adorned by a chignon of matted locks. He should be equipped with all [suitable] ornaments, [and] adorned with white garlands; he should consume [only the pure ritual gruel-offering known as] caru; he should observe the chaste conduct of a student; he should venerate Śiva, the fire (śivāgni-pūjaka) and his Guru. [...]”.

Shaiva (शैव, śaiva) or Shaivism (śaivism) represents a tradition of Hinduism worshiping Shiva as the supreme being. Closely related to Shaktism, Shaiva literature includes a range of scriptures, including Tantras, while the root of this tradition may be traced back to the ancient Vedas.
