תַּנּוּר שֶׁנָּפַל לְתוֹכוֹ מִטִּיחַ הַטִּיט, אִם אֶפְשָׁר לֶאֱפוֹת וְלִצְלוֹת בּוֹ בְּלֹא גְּרִיפָה וְלֹא יִתְחָרֵךְ הַפַּת אוֹ הַצְּלִי, אָסוּר לְגָרְפוֹ, מִפְּנֵי שֶׁהוּא מְטַלְטְלוֹ שֶׁלֹּא לְצֹרֶךְ; אֲבָל מֻתָּר לְהַשְׁכִּיב הָאֵשׁ וְהָאֵפֶר שֶׁבּוֹ כְּדֵי שֶׁיִּהְיֶה חָלָק וְלֹא יִגַּע בַּפַּת כְּלָל, אַף עַל פִּי שֶׁאִם הָיָה נוֹגֵעַ בּוֹ לֹא הָיָה כְּדֵי לְחָרְכוֹ; אֲבָל אִם יֵשׁ בַּטִּיחַ שֶׁנָּפַל לְתוֹכוֹ כְּדֵי לַחְרֹךְ הַפַּת אוֹ הַצְּלִי אִם הָיָה נוֹגֵעַ בָּהֶם, אַף עַל פִּי שֶׁבְּלֹא גְּרִיפָה הָיָה אֶפְשָׁר לֶאֱפוֹת וְלִצְלוֹת בּוֹ, כֵּיוָן שֶׁהָיָה מִתְחָרֵךְ מֻתָּר לְגָרְפוֹ דְּחָשִׁיב טִלְטוּל לְצֹרֶךְ. וְדַוְקָא בַּתַּנּוּרִים שֶׁלָּהֶם שֶׁהָיוּ מְדַבְּקִים הַפַּת סְבִיבָם וְאֵין צְרִיכִים לְגָרְפָם אֶלָּא מֵהַטִּיחַ שֶׁנָּפַל לְתוֹכוֹ, אֲבָל תַּנּוּרִים שֶׁלָּנוּ כֵּיוָן שֶׁאִי אֶפְשָׁר לֶאֱפוֹת בָּהֶם בְּלֹא גְּרִיפָה, מֻתָּר לְגָרְפוֹ מֵהָאֵפֶר וְהַגֶּחָלִים, וְאַף עַל פִּי שֶׁהוּא מְכַבֶּה, אִי אֶפְשָׁר בְּלֹא כֵן, וּכְשֵׁם שֶׁמֻּתָּר לְהַבְעִיר לְצֹרֶךְ אֹכֶל נֶפֶשׁ כָּךְ מֻתָּר לְכַבּוֹת לְצֹרֶךְ אֹכֶל נֶפֶשׁ, וַהֲרֵי זֶה כְּמַנִּיחַ בָּשָׂר עַל הַגֶּחָלִים, וְכֵן נָהֲגוּ.

It is forbidden to take wood from among logs to stoke the fire in an oven, for this constitutes repairing a vessel. If an oven has plaster-clay fall into it: if it is possible to bake and roast in it without sweeping and the bread or roast will not be scorched, it is forbidden to sweep it out because one is moving it unnecessarily. But it is permitted to flatten the fire and the ash in it so that it will be smooth and will not touch the bread at all, even though if it were touching it, it would not be enough to scorch it. However, if there is enough of the plaster that fell into it to scorch the bread or roast if it were touching them, even though without sweeping it would be possible to bake and roast in it, since it scorches, it is permitted to sweep it out, for this is considered moving for a purpose. This applies specifically to their ovens, where they would attach the bread around the sides and only needed to sweep out the plaster that fell into it. But our ovens, since it is impossible to bake in them without sweeping, it is permitted to sweep it from the ash and coals, and even though one extinguishes [fire in the process], it is impossible otherwise. And just as it is permitted to kindle for the purpose of food preparation, so too it is permitted to extinguish for the purpose of food preparation. This is like placing meat on coals, and such is the custom.

Se’if 5ה׳

תַּנּוּר וְכִירַיִם חֲדָשִׁים, אֵין סָכִין אוֹתָם בְּשֶׁמֶן וְלֹא טָשִׁין אוֹתָן בְּמַטְלִית, אֲבָל מֻתָּר לְהַסִיקָן אֲפִלּוּ הֶסֵק רִאשׁוֹן, וּבִלְבַד שֶׁלֹּא יְפִיגֵם בְּצוֹנֵן כְּדֵי לְחָסְמָן. וְאִם הֻסְקוּ יוֹתֵר מִדַּאי וְהֻצְרְכוּ לַהֲפִיגָן בְּצוֹנֵן כְּדֵי לֶאֱפוֹת בָּהֶן, מֻתָּר. לְפִיכָךְ מֻתָּר לִשְׁרוֹת בְּמַיִם הַמְכַבֶּדֶת שֶׁמְּכַבְּדִין בָּהּ הַתַּנּוּר, אַף שֶׁמְּכַבָּה.

A new oven and new stoves may not be coated with oil nor wiped with a cloth, but it is permitted to heat them even for the first heating, provided that one does not cool them with cold water in order to seal them. And if they were heated too much and it became necessary to cool them with cold water in order to be able to bake in them, it is permitted. Therefore, it is permitted to soak the broom with which one sweeps the oven, even though this extinguishes [coals].
