Ennamba z’amangu mu bitundu n’omutindo gw’ebyuma bya ggaasi¶

Ebibuuzo ebitera okubuuzibwa¶

Lwaki okuggyako ekyuma ekibugumya amazzi ekitaliiko ttanka mu kiseera ky’obutiti kireetera ekyuma ekiwanyisiganya ebbugumu eky’ekikomo okukutuka?¶

Bannannyini mayumba batera okulowooza nti ekyuma ekibugumya amazzi ekitaliiko ttanka ya ggaasi kikozesa ekyuma kyayo eky’okwokya ggaasi okwekuuma obutafuuka bbugumu, oba nti okuggyako yuniti etakola bulungi mu kiseera ky’obutiti, kwegendereza okutali kwa bulabe. Mu butuufu, ekyuma ekibugumya amazzi ekitaliiko ttanka tekikuma omuliro mu kyokya kyakyo eky’amaanyi ekya ggaasi okusobola okukuuma firiigi kubanga okukikola nga amazzi tegakulukuta kyandifumbiddwa mangu amazzi agayimiridde ne gafuuka omukka. Mu kifo ky’ekyo, buli yuniti etaliiko ttanka yeesigamye ku bulooka obutono obw’amasannyalaze obwa vvuloti 120 oba 230 obw’amasannyalaze obwa seramiki obunywezeddwa butereevu ku payipu z’ekikomo ez’omunda. Kasita yuniti esigala ng’eyungiddwa mu kifo ky’amasannyalaze ekiramu, ne bwe kiba nti ggaasi azikiddwa oba nga koodi y’ensobi eyaka, bulooka z’amasannyalaze ezo zikuuma ekyuma ekiwanyisiganya ebbugumu waggulu w’okutonnya. Singa oggyamu yuniti nga tosoose kufulumya mazzi mu vvaalu za service eza wansi, empewo ennyogovu efuuwa wansi mu kifo ekifulumya empewo ejja kufuuka bbugumu era ekutuse ekyuma ekiwanyisiganya ebbugumu eky’ekikomo mu ssaawa ntono.

Payipu efulumya amazzi mu buveera obufuuse bbugumu ebweru w’ennyumba ereeta etya Error Code 11 oba Error Code 12?¶

Ebyuma ebibugumya amazzi ebitaliimu ttanka ebikola obulungi biggya ebbugumu lingi nnyo mu ggaasi afuluma ne kiba nti liita 2 ku 4 (ggaloni 0.5 ku 1) buli ssaawa ez’amazzi ag’amazzi aga asidi gafuumuuka munda mu kifo eky’okubiri ekiwanyisiganya ebbugumu ne gafuluma nga gayita mu payipu entono ey’akaveera eya milimita 13 ku 19 (yinsi 0.5 ku 0.75). Awali payipu eyo entono efuluma ng’eyita mu bbugwe ow’ebweru oba ng’eyita mu galagi etabuguma, empewo ey’omu kiseera eky’obutiti efuula empewo ekulukuta empola n’efuuka pulagi ya ice ennywevu. Oluvannyuma lw’okuzibikira, amazzi agafuuse amazzi gadda emabega munda mu bbugumu, ne gajjuza omutego ogw’omunda, ne gakulukuta waggulu mu kisenge eky’okwokya, ne gannyika omuggo gwa sensa y’ennimi z’omuliro n’ekyuma ekikuma omuliro okutuusa kompyuta lw’eggalawo ku Error Code 11 (No Ignition) oba Error Code 12 (Flame Loss).

Njawulo ki eriwo wakati wa Error Code 11 ne Error Code 12 ku Rinnai, Noritz, oba Rheem tankless water heater?¶

Error Code 11 (eyenkana Navien E003 oba Takagi 111) kitegeeza "No Ignition": bw'oggulawo ttaapu y'amazzi agookya, ttabiini y'amazzi agookya yeekulukuunya era igniter n'ekwata ennimi z'omuliro, naye tewali nnimi za muliro ziteekebwawo, ebiseera ebisinga olw'okuba vvaalu ya ggaasi enkulu eggaddwa, ttanka ya propane njereere oba omukutu gwayo ogw'ebweru ogwa regulator gusibiddwa waggulu, empewo esibiddwa mu layini ya ggaasi, oba amazzi aga condensate aga backed-up ganjadde mu bbugumu nga tegannatandika. Error Code 12 (enkanankana ne Navien E012 oba Takagi 121) kitegeeza "Okufiirwa Ennimi z'omuliro": ekyokya kikwata bulungi, kyokya okumala sekondi oba eddakiika ntono, n'oluvannyuma ne kizikira mu bwangu wakati mu cycle, okusinga kiva ku layini ya condensate efuuse bbugumu ekitundu ng'ekulukuta amazzi mu kyokya, omuzira ne guziyiza payipu za PVC ez'ebweru eziyingira/okufulumya, a omuggo omucaafu ogw’okutereeza ennimi z’omuliro, oba puleesa ya layini ya ggaasi etamala ng’ekikoomi ky’awaka kikuba mu kiseera kye kimu.

Nnyinza ntya okukuuma amazzi agannyogoga nga gakulukuta mu nnyumba yange singa ekyuma kyange ekibugumya amazzi ekitaliiko ttanka ekikyusa ebbugumu kifuuka bbugumu ne kyawukana?¶

Singa ekyuma kyo ekibugumya amazzi ekitaliiko ttanka kifuuka bbugumu ne kikutula ekyuma kyakyo eky’ebbugumu eky’ekikomo eky’omunda, tolina kuva mu nnyumba yo yonna nga tolina mazzi gakulukuta ng’olinda ennaku z’okugikyusa yuniti. Simple walk up to the plumbing manifold directly under the tankless unit era okyuse byombi Blue Cold-Water Inlet Isolation Valve ne Red Hot-Water Outlet Isolation Valve diguli 90 nga zeesimbye ku payipu (ekifo kya OFF). Okuggala vvaalu ezo ebbiri ez’okwekutula kikutula ddala ekyuma ekibugumya amazzi ekitaliimu ttanka ekikulukuta ku nkola ya ppipa mu maka go, ekikusobozesa okuleka vvaalu eggalawo amazzi mu nnyumba yo enkulu nga nzigule nnyo kale kaabuyonjo zonna, sinki n’ebyuma bibeere n’amazzi agannyogoga aga bulijjo.

Lwaki ttaapu zange ennyogovu zaasigala nga zikola ate ttaapu zange ezibuguma ne zilekera awo okukulukuta ddala mu kiseera ky’ennyogoga?¶

Amazzi agannyogoga bwe gakulukuta mu ngeri eya bulijjo ku buli sinki mu nnyumba yo naye ng’okoleeza ttaapu yonna ey’amazzi agookya ne kivaamu zero amazzi agakulukuta (si wadde amazzi agannyogoga agava ku ludda olw’ebbugumu), ekizibiti kibeera ku ccupa emu amazzi gonna agookya mwe galina okuyita: ekyuma ekibugumya amazzi ekitaliiko ttanka kyennyini oba payipu zaakyo ezirabika/okufuluma mu galagi, attic, oba exterior wall recess. Olw’okuba amakubo g’ebiyumba eby’ekikomo munda mu kifo ekiwanyisiganya ebbugumu ekitaliiko ttanka galina obugazi bwa mmita 6 ku 12 zokka (yinsi 0.25 ku 0.5) era nga gatuula wansi ddala w’omukka oguggule ogw’ebweru, gafuuka bbugumu edda nga payipu ennene ez’oku bbugwe z’awaka tezinnabaawo. Ggalawo Blue Cold Inlet Valve amangu ddala era osaanuuse unit mpola n’ekyuma ekikala enviiri ng’emikutu gy’amazzi agafuluma wansi giggule.

Nsobola okussa amaanyi mu kyuma kyange ekibugumya amazzi ekitaliiko ttanka ya ggaasi nga nkozesa bbaatule ya kompyuta UPS backup mu kiseera ky’obutiti?¶

Yee, kubanga ekyuma ekibugumya amazzi ekitaliiko ttanka ya ggaasi kikozesa ggaasi ow’obutonde oba propane okukola ebitundu 100 ku 100 eby’ebbugumu lyakyo ery’ebbugumu era kikozesa amasannyalaze gokka okuddukanya circuit board yaakyo, exhaust blower fan, n’ebintu eby’amasannyalaze ebikuuma firiigi (esika watts 75 ku 200 zokka). Naye, olina okukozesa "Pure Sine Wave" (True Sine Wave) UPS battery backup ebalirirwa ku 1,000 VA okutuuka ku 1,500 VA, never embalirira "Simulated / Modified Sine Wave" kompyuta UPS. Amayengo ga sine agakyusiddwa gafulumya amayengo ga square aga steppped agaleetera motor ya ttanka etaliiko sipiidi ya combustion blower motor okubuguma ennyo, okuyimirira oba okusuula koodi z’ensobi ez’embiro za fan.

Ekitabo kino kya mawulire era tekidda mu kifo kya ggaasi alina layisinsi oba master plumber. Toggulawo kisenge kya kwokya ekissiddwako ssimu oba ggwe kennyini okutereeza puleesa za ggaasi za manifold, era lowooza ku ky’okukola omusomo gw’okwetegekera embeera ez’amangu awaka n’obujjanjabi obusookerwako ng’oyita mu Red Cross oba St John Ambulance.
