Over time the wax wears down, which means a cylinder usually lasts 1 to 2 years. You can make it last longer by unscrewing it over winter while the vents stay shut. We don't recommend them for coastal or beachfront spots, as the conditions there are too harsh.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTroubleshooting:\u003c\/strong\u003e Vent not closing? Check it isn't catching on the roof ribs next to the vent opening. Strong wind can push the vent along the ridge, so just slide it back into the centre channel. The cylinder is designed to open once it's above 17°C (63°F), so to check the vent closes fully, disengage it for a moment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow to Install, Plus Tips:\u003c\/strong\u003e\u003cbr\u003e\u003ciframe title=\"Installation Video\" src=\"https:\/\/www.youtube.com\/embed\/kXM_DaznLwY\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003cbr\u003e\u003ciframe title=\"Troubleshooting Video\" src=\"https:\/\/www.youtube.com\/embed\/CVxueDu03vA\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"Winter Gardenz","offers":[{"title":"Default Title","offer_id":68339192070295,"sku":"AV01R","price":59.95,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2828\/4311\/files\/auto-vent-replacement-cylinder__91427.jpg?v=1794607239","url":"https:\/\/junglestory.co.nz\/zh-hant\/products\/auto-vent-replacement-cylinder","provider":"Jungle Story ","version":"1.0","type":"link"}
