The Wildfire HE900 PCF will fit into any precast flue fireplace. This patent pending product provides the solution to provide a large format glass fronted gas fire suitable for installation into these extremely small flues. For decades the consumer has been limited to shallow and narrow gas fires which, although provide a great visual and efficient spot heating method, cannot even begin to compare to the new Wildfire HE900 range of products. With a massive 83% efficient 5.1kW output, stunning log fuel set and dancing flames, the precast flue market has changed. When you talk to your local fireplace retailer and he asks you what sort of flue you have, make sure you tell him that you want to see the HE900PCF.
