WhatsApp UsTHE JETMASTER MERCURY
The Mercury is a slow-combustion fireplace that stands on its own, with no wall to build into. Load it with wood and watch the flames through the ceramic glass window while convection and radiated heat warm the room. Run the 150 mm flue from the top or the rear, whichever suits your space. At 98 kg, it is a solid piece of kit.
MAKE YOURSELF AT HOME
A cold winter morning, a basket of dry logs and the fire already going. Pull a chair closer, watch the flames through the glass and let the room warm up around you. By evening, everyone finds a reason to sit nearby.
The flue pipe, hearth plate, log basket, bench and blankets are not included. Confirm the flue route, hearth and clearances with an independent installer.
BEFORE THE FIRST COLD NIGHT
THE HEAT
The Mercury warms the room with convection and radiated heat. The Mercury's nominal heat output is listed as 8.1 kW, with an approximate heating area of 100 m² as a guide.
THE VIEW
A ceramic glass window lets you watch the wood burn while you settle in and enjoy the warmth.
THE FLUE
The 150 mm round flue can leave from the top or the rear. Plan the route first, then choose flue pipes and a cowl under Complete your setup, or ask us for a flue quote.
MEASURE BEFORE YOU PLAN
Plan the fireplace, hearth and flue together.
These are the fireplace's own dimensions, with the height taken to the top of the flue collar. Have your installer confirm the clearances, the hearth, the flue route and the actual unit before you build.
GOOD TO KNOW
Plan the fireplace, hearth and flue route together before any building work.
The Jetmaster Mercury fireplace: a freestanding slow-combustion unit with a ceramic glass viewing window and a 150 mm round flue connection. Flue pipes, a cowl and an escutcheon plate are chosen separately under Complete your setup.
Wood. That's the listed fuel for the Mercury. Ask us before you plan to burn anything else.
The Mercury has a listed nominal heat output of 8.1 kW, from convection and radiated heat, and an approximate heating area of 100 m². Treat the area as a guide, not a promise for every room. The Output Calculator uses 8.1 kW to compare with your room.
The round flue connection is 150 mm. Top and rear outlet configurations are listed, so plan which way your flue will run. Your installer must follow the unit's installation manual. Ask us which parts your route needs before you order.
No. Choose flue pipes and a cowl under Complete your setup, or send a photo and measurements for a flue and configuration quote. The optional mild-steel flue pipes are 150 mm in diameter and 1,200 mm long.
It is a round, black mild-steel plate in two halves that gives a neat finish where the flue passes through the ceiling. The option on this page is for a 150 mm flue.
The unit is 560 mm wide, 330 mm deep and 667 mm high to the top of the flue collar, and it weighs 98 kg. Have your installer confirm the clearances to walls and furniture, and the hearth size, for your room.
Freestanding. The Mercury stands on its own in the room; it is not a built-in fireplace insert.
The Mercury's combustion firebox has a three-year Jetmaster warranty from the invoice date against defects in materials and workmanship, subject to normal use and maintenance. Exclusions apply, including flame-path parts and the glass. Ask us for the full terms.
