It runs at 13kW nominal, or down to 4.3kW, at 81.3% efficiency, enough for large open-plan spaces.\u003c\/p\u003e\u003ch2\u003eWhy choose the Octave 90i\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWindow close to a metre wide, with a 50mm four-sided frame included.\u003c\/li\u003e\n\u003cli\u003e13kW nominal, turning down to 4.3kW; 81.3% efficient, energy class A+, Ecodesign ready.\u003c\/li\u003e\n\u003cli\u003eTakes logs up to 800mm long.\u003c\/li\u003e\n\u003cli\u003eAdjustable flue baffle that your installer can tune to the chimney.\u003c\/li\u003e\n\u003cli\u003e200mm top flue and an optional 100mm outside air kit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWill it suit your space?\u003c\/h2\u003e\u003cp\u003eAs a rough guide, an average room needs about 1kW for every 14 cubic metres, so its 13kW suits around 182 cubic metres. Older, draughty or high-ceilinged rooms need more, and a heat-loss check by your installer gives the right answer.\u003c\/p\u003e\u003cp\u003eThe 90i is 535mm high, 940mm wide and 440mm deep, and it weighs 150kg. The opening needs at least 80mm clearance round the casing, and optional vents at the top and bottom of the chamber recover more heat.\u003c\/p\u003e\u003cdiv class=\"gf-desc-specs\"\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eOpus Octave 90i inset\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeat output\u003c\/th\u003e\n\u003ctd\u003e13kW nominal; down to 4.3kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEfficiency\u003c\/th\u003e\n\u003ctd\u003e81.3%, energy class A+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFuel\u003c\/th\u003e\n\u003ctd\u003eWood logs only, up to 800mm long\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003eH 535 x W 940 x D 440mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e150kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame\u003c\/th\u003e\n\u003ctd\u003e50mm four-sided frame included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFlue\u003c\/th\u003e\n\u003ctd\u003e200mm, top outlet (centre 194mm from the back)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutside air\u003c\/th\u003e\n\u003ctd\u003e100mm, with the optional direct air kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInstallation gap\u003c\/th\u003e\n\u003ctd\u003eAt least 80mm between the casing and the chamber walls\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEcodesign\u003c\/th\u003e\n\u003ctd\u003eEcodesign ready\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSmoke control\u003c\/th\u003e\n\u003ctd\u003eNot on DEFRA's exempt list for England\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e3 years (glass, seals, grate and firebricks excluded)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003c\/div\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cp\u003eA heat-resistant glove; the baffle plate is packed inside the firebox.\u003c\/p\u003e\u003ch2\u003eInstallation and safety\u003c\/h2\u003e\u003cp\u003eHave it fitted by a HETAS-registered installer or signed off by Building Control, with a carbon monoxide alarm in the same room.
