OPTIMUM 700-60 Series
Fresh air supply
The fresh air supply can be adjusted using the supplied handle. Maximum air supply for combustion is achieved when the slidable handle is moved completely to the right.
It is best to slide the lever completely to the right when lighting the fire. Once the kindling wood is nicely ignited after 10 to 15 minutes, the air regulator can be put back in the middle position.
If the handle is in the middle position, the fireplace burns at nominal heat output. In this position, the combustion and efficiency are best when the chimney is drawing at minimum 12 Pascal.
Moving the handle further to the left reduces the air supply and this decreases the output of the fireplace. When you slide the handle further to the left from the middle position, this reduces the air supply in the fireplace. Once the air supply is in the fully left position, the fire in the fireplace will be extinguished.
Original | Triangle | Round
Like the 'Original' vertical cast-iron slats, the 'Triangle' and 'Round' versions exude minimalism. The 'Triangle' cast-iron slats represent a more angular approach to the inside of the fireplace, while the 'Round' cast-iron slats - based on a design by Belgian architect Benoit Viaene - are characterised by gentle curves.
The common denominator is the elegant rhythm in both surfaces, which creates an interesting dialogue with the warm light of the fire. The sleek and refined finish of the 'Original', 'Triangle' and 'Round' versions fits perfectly into any interior (in any fireplace) and is also a real eye-catcher, whether the fire is burning or not.
Ceramic concrete look
In our pursuit of offering you the most diverse and adaptable choices, we like to introduce a captivating variant of the Optimum interior finishes. In addition to its exceptional cast iron design, the Optimum is available in 'Ceramic' material with a striking concrete look.
Elevate your fireplace aesthetics
The 'Ceramic' material with a concrete look brings a modern, industrial charm to your space, while still maintaining the high-performance features that define that material. This new variant is designed to not only keep you warm and cozy but also to serve as a stylish centerpiece in your home.
Interior finishing colours
Black | Terracotta
Though the Standard 'Black' lacquer already offers the most beautiful timeless base for any fireplace, Metalfire add a new color to their cast iron finishes for closed wood-fires.
As the name predicts, 'Terracotta' is a vivid orange-red lacquer, reminiscent of typical Mediterranean sceneries. A constant reminder of the sunniest of settings and a welcome pop of color during darker days. Whenever, wherever, 'Terracotta' oozes pure warmth and abundance.
Finishing frame | Cold door handle
The standard Metalfire finishing frame is 10 mm thick and is available in lacquered 'Black', 'Terracotta', or 'Maple gold', allowing you to choose a finish that best complements your interior design.
