FAQ Frequently Asked Questions<\/h1>\n

We have a set of Frequently Asked Questions which cover our products, as well as installation and purchase\/delivery queries. Please note that this page is in BETA stage, which means it will be updated on a regular basis over the next few weeks.<\/p>\n

All our installation guides are available as PDF downloads, so feel free to click here<\/strong><\/a> to download. The guides contain far more detail on installation along with important safety advice, as well as guarantee requirements.[\/vc_column_text][vc_column_text css=”.vc_custom_1528456131428{margin-bottom: 0px !important;}”]\n<\/a>

Installation Questions<\/h3>\n[\/vc_column_text][vc_toggle title=” Why do I have to put an vent opening in the wall”]An air vent is required for safety reasons, to ensure that there is enough oxygen available for a stove to burn wood efficiently. The stove requires combustion air, but DEFRA approved appliances do not always need external air vents.<\/p>\n

Most houses in the UK don’t need any extra ventilation if the stove is rate at 5kW or less. An air vent is needed for anything above this.[\/vc_toggle][vc_toggle title=” How can I reduce downdraft?”]Down draft issues can be caused by a number of reasons, such as insufficient height of the flue and also pressure zones.<\/p>\n

The first test is to try and raise the chimney out of the pressure zone. This can be done by the means of a temporary flue to test if the procedure has worked, then a permanent flue size increase after this.[\/vc_toggle][vc_toggle title=”How can I eliminate or prevent condensates in flue?”]It is important to maintain sufficiently high flue gas temperatures in order to avoid condensate and acid corrosion problems, and to ensure complete combustion of the fuel. The chimney system should be designed to ensure the flue gas temperature are maintained as long as possible<\/p>\n

Condensates won\u2019t be entirely removed, but disposal is important, so any \u2018horizontal\u2019 runs should allow for a minimum 3\u00b0 slope and therefore, where required, 87\u00b0 bends and 93\u00b0 tees must be used rather than 90\u00b0 bends and tees to allow the condensate to run off and a tee plug or drain cap used.<\/p>\n

In external systems a drain should be fitted to ensure no build up of excess rainwater or slight condensation[\/vc_toggle][vc_toggle title=” How can I increase updraft”]Increasing the diameter of the flue will help to increase the draft. In some cases, fans are used, but this isn’t entirely necessary and would be a last resort.[\/vc_toggle][vc_toggle title=” Distance to combustibles?”]We have an extensive article about distance to combustibles which has all the information needed – click here<\/a>.<\/p>\n

On that page, you will find information on distance to combustibles for all our range:<\/p>\n
