He shall not blow fire with the mouth; nor shall he look at a naked woman. He shall not throw an unclean thing into fire; nor shall he warm his feet at it.—(53)

Medhātithi’s commentary (manubhāṣya):
Fire should be blown with deer-skin-fans and such things.

‘He shall not look at a naked woman’—‘apart from sexual intercourse,’ says another Smṛti-text.

‘Unclean thing’—‘ameḍhya—‘medha’ means- sacrifice; ‘medhya’ is fit for use at sacrifice; and ‘amedhya’ is unfit for use at sacrifices; such things, for instance, as onions, urine, excreta, and so forth. Anything like this, he shall not throw into fire.

He shall not raise his feet directly towards the fire and warm them at it. There is no objection to the feet being covered and then warmed for the purpose of exciting perspiration.—(53).

This verse is quoted in Aparārka (p. 181);—and in Mitākṣarā (on 1.137).
