What you'll need
Everything to get this stove lit
A stove on its own isn't enough. Here's what comes in the box, what else you'll need, and what your installer brings.
In the box
- The stove and the manufacturer's installation and user manual
You'll also need
- A carbon monoxide alarm. Required by law in the room with the stove.
- Stove pipe to connect it to the flue. Your installer will tell you the length.
- A hearth for it to stand on, if you don't already have one.
- A chimney liner or twin-wall flue. Your installer supplies this.
Added. It goes in your basket with the stove when you press Add to basket.
Your installer brings
A stainless steel liner sized to the stove and a register plate to seal the chimney, usually after the chimney has been swept and checked.
A twin-wall insulated flue, taken up through the ceiling and roof or up an outside wall.
Fitting, testing and a certificate showing it meets Building Regulations. Keep it for your home insurer and for when you sell.
Ask for one quote that covers the survey, flue, fitting and certificate. Using someone who isn't HETAS registered? Your local building control must approve the work before you use the stove.

About this product
Will it suit your space?
As a rough guide, an average room needs about 1kW for every 14 cubic metres, so its 5.5kW suits around 77 cubic metres. Older, draughty or high-ceilinged rooms need more, and a heat-loss check by your installer gives the right answer.
Firepower gives its size as 970mm high, 475mm wide and 365mm deep. The flue leaves from the rear only, so check the flue route before you order. Opus asks for 250mm to combustible materials behind and 350mm at the sides.

Questions
Can I really cook on it?
Yes. The top is a black ceramic cooking surface and Opus channels the flue gases directly beneath it, so it heats while the stove is lit. Opus presents it as a way to cook during a power cut.
What is the difference between the D and LS versions?
The Aria D Cook Top has a door over the log store; the Aria LS Cook Top leaves it open. Output, efficiency and size are the same.
Can the flue go out of the top?
No. Opus lists the cook top version with a rear flue outlet only, centred 802.5mm from the floor.
