When people begin operating their appliances again, the number of repair requests increases immediately. So we took the opportunity to ask our technical service experts what they thought were the most common causes of heating units breaking or malfunctioning. Here are 5 things they told us.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<section class=\"s_text_image o_colored_level pt0 pb16\" data-snippet=\"s_image_text\" data-name=\"Image - Text\">\n<div class=\"container\">\n<div class=\"row align-items-center\" title=\"\" data-original-title=\"\" aria-describedby=\"tooltip31648\">\n<div class=\"col-lg-6 pt16 pb16 o_colored_level\"><\/div>\n<\/div>\n<\/div>\n<\/section>\n<p>[\/vc_column_text][vc_column_text css=&#8221;&#8221;]<\/p>\n<h2>#1 &#8211; CHIMNEY POORLY CALIBRATED FOR THE APPLIANCE<\/h2>\n<p>Since we can&#8217;t see it, it&#8217;s easy to forget that the exhaust is a crucial part of an installation. In fact, a large part of the proper functioning of a heating appliance comes from its exhaust. Often, we see people who think they can replace one fireplace with another without checking their chimney because it has always worked well. Unfortunately, it may not be compatible and\/or properly adjusted according to the new unit. A chimney that lacks draft can cause smoke in the house or flames that do not rise. An incorrect air supply, either too much or not enough, can also cause the appliance to malfunction and damage it eventually.[\/vc_column_text][vc_column_text css=&#8221;&#8221;]<\/p>\n<h2>#2 &#8211; Skipping Annual Maintenance<\/h2>\n<p>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;&#8221;]A visual inspection by a good, experienced chimney sweep can help detect signs of premature wear. By doing so, corrections can be made before irreversible damage occurs to the appliance. Indeed, problems such as a worn gasket that let in too much air, a flame deflector that is too used or a chimney that is drafting excessively due to a change in the environment can be easily identified.[\/vc_column_text][vc_empty_space][vc_empty_space css=&#8221;.vc_custom_1729863113491{background-color: #d99d30 !important;}&#8221;][\/vc_column_inner][vc_column_inner width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1729863310474{border-top-width: 5px !important;border-right-width: 5px !important;border-bottom-width: 5px !important;border-left-width: 5px !important;border-left-style: solid !important;border-right-style: solid !important;border-top-style: solid !important;border-bottom-style: solid !important;border-radius: 2px !important;border-color: #d99d30 !important;}&#8221;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h4 style=\"text-align: center\"><span style=\"color: #ffffff\">Did you know&#8230;?<\/span><\/h4>\n<p style=\"text-align: center\">The environment outside your home can have an impact on the operation of your fireplace or stove. Indeed, a tree or hedge that has grown, the addition of a second floor on the house or at the neighbours or a new building nearby, are all things that can change the wind corridors and, by the same token, influence the draft of the chimney.<\/p>\n<p>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][vc_empty_space][vc_column_text css=&#8221;&#8221;]<\/p>\n<h2>#3 &#8211; NOT READING THE INSTRUCTION MANUAL<\/h2>\n<p>Many will tell us: &#8220;No need to read a manual to make a fire&#8221;. Okay, but operating and optimizing the performance of your heating appliance is another matter. Especially with the modern stoves and fireplaces that we have. We are far from a masonry fireplace open to the outside. The appliances nowadays retain much more heat in the combustion chamber in order to comply with the demanding new emission standards. If the appliance is not operated properly, it can wear out more quickly and overheat in a way that can damage the walls and even the chimney.<\/p>\n<h2>#4 \u2013 Using Poor Quality WOOD<\/h2>\n<p>Burning quality wood is like using supreme gasoline for your car. Softwoods that contain large amounts of resin or ones that have a high level of humidity create a lot of creosote which will gradually cause a loss of efficiency and, if poorly maintained, could cause a chimney fire.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_empty_space][vc_row_inner][vc_column_inner width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;31299&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; css=&#8221;&#8221;][vc_column_text css=&#8221;&#8221;][\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1729863310474{border-top-width: 5px !important;border-right-width: 5px !important;border-bottom-width: 5px !important;border-left-width: 5px !important;border-left-style: solid !important;border-right-style: solid !important;border-top-style: solid !important;border-bottom-style: solid !important;border-radius: 2px !important;border-color: #d99d30 !important;}&#8221;][vc_empty_space][vc_column_text css=&#8221;&#8221;]<\/p>\n<h4 style=\"text-align: center\"><span style=\"color: #ffffff\">What is creosote?<\/span><\/h4>\n<p style=\"text-align: center\">\u201cWhen fuel burns, it creates smoke.

This intense and repetitive heat will eventually age the heating appliance prematurely in the same way that an excessively drafted chimney would. Be sure to use this type of log responsibly to protect the lifespan of your stoves and fireplaces.[\/vc_column_text][vc_empty_space][vc_column_text css=&#8221;&#8221;]There are other causes, but these are a good starting point when you want to use your heating appliance in a way that prevents certain breakdowns or malfunctions.
