The Metalfire Avenue Gas Fire Front is the classic configuration: a closed, high-efficiency gas fireplace with a single frameless glass face, built into the wall as the focal point of the room. With 15 model sizes it fits almost any project - from the compact 800mm models to the 1600mm statement fires, and the Avenue L series whose taller openings, up to 950mm high, give the flame room to rise. Brick-lined variants are available on selected sizes.
Output runs from 7.0 to 14.0kW at efficiencies up to 87%. Metalfire's Double Burner lets you run the inner burner alone for ambience at around half output, while Eco Wave modulates the flame automatically, saving up to 40% gas. The RF remote controls flame height, room temperature and timers, and the frameless glass lifts away without tools for cleaning. Natural gas as standard, with propane and biopropane compatibility, and tested for hydrogen blends up to 40%.

What Makes The Metalfire Avenue Gas Fires Exceptional
Dual Burning
Two separate burners sit within the fire. Run the inner burner alone for a gentle flame at around half output - atmosphere without the heat - or bring the outer burner in for full depth, full flame and full warmth.
Eco Wave
The flame modulates between high and low on its own, moving like a real wood fire while using up to 40% less gas. Set it, and the fire does the rest.
H2
Ready for the future of gas. Every Avenue is tested on hydrogen blends up to 40% with no modification needed, so the fire is prepared as the UK gas grid changes.
Line Burner
A clean, linear flame running the full length of the fire with no visual interruption - fire as architecture, made for minimalist interiors where presence matters more than bulk.
Technical Specifications
Every dimension, every material choice, every specification has been considered. Built to exacting standards for those who demand excellence.
Decorative Burner Toppings for The Metalfire Avenue Gas Fire
The finishing touch for the fire bed. Four decorative toppings dress the burner to suit the room - each changes the character of the fire, and all are interchangeable.
Wood Chips
Dark, charred-wood chips for a rugged fire bed - the look of a fire that has been burning for hours.
Vermiculite
Fine mineral granules forming a clean, even bed that glows gently around the flame.
Grey Pebbles
Smooth grey stone for a calm, contemporary fire bed - the quiet option.
White Pebbles
Crisp white stone that brightens the fire bed and sets a sharp contrast against the flame.
Log Burner Finish
Smoke Style Ceramic Logs
Dark, charred ceramic logs with the look of a fire mid-burn - the contemporary choice, and the standard finish on 60cm-opening models.
Classic Style Ceramic Logs
Natural brown ceramic logs in the style of freshly laid firewood - the traditional fire-bed look.

Frequently Asked Questions
What is the Metalfire Avenue Gas Fire Front?
A closed, high-efficiency gas fireplace with a single frameless glass face, built into the wall as the focal point of one room. It is made to measure in Belgium by Metalfire, across 15 model sizes with outputs from 7.0 to 14.0kW.
What sizes does the Metalfire Avenue Front come in?
Fifteen model sizes, from an 800mm-wide opening up to 1600mm statement fires. The Avenue L series adds taller openings - up to 950mm high - for a more vertical flame picture, and brick-lined variants are available on selected models.
How much heat does the Metalfire Avenue Front produce?
Between 7.0 and 14.0kW depending on the model, at efficiencies of 80.0-87.0%. That is genuine primary-heating territory for larger rooms, delivered through radiant warmth from the glass and a convection chamber fitted as standard.
What is the Avenue L series?
The taller-bodied Avenue models - 1300mm wide with opening heights of 750, 850 or 950mm and output up to 14kW. The L series suits larger rooms and higher ceilings where a standard-height fire would look lost.
What fuel does the Metalfire Avenue Front use?
Natural gas (G20) as standard, with full compatibility for propane (G30)
What flue does the Metalfire Avenue Front need?
A concentric balanced flue system, which draws combustion air in and vents exhaust through the same assembly - no existing chimney is required, though it can connect to one. Your installer confirms the routing after a survey.
How do you control the Metalfire Avenue Front?
With the RF remote control included: on and off, flame height, a room-temperature setpoint, a programmable timer, and Eco Wave modulation. The Double Burner function switches between 50% and 100% output.
What interior finishes are available on the Metalfire Avenue Front?
Six interior linings - flat steel, asymmetric steel slats, ribbed cast iron, round or triangle cast iron, and a ceramic concrete-look - with exterior finishing frames in Black, Terracotta or Maple Gold. Your choice shapes how the flames read against the back of the fire.
How do you clean the glass on the Metalfire Avenue Front?
The frameless glass panel lifts away with the suction cups provided - no tools needed - so cleaning takes minutes. An anti-reflective glass option is available for an even clearer view of the flame.
Who installs the Metalfire Avenue Front gas fire?
Gas fires must be installed by a Gas Safe registered engineer. Our team installs within our local radius, handling survey, gas connection and commissioning; further afield we supply UK-wide and advise your installer. Call 01628 290142 to talk it through.
