When Alastair Denison wanted to install a wood burning stove into his 15th century townhouse in the historic Dutch Quarter of Colchester, he turned to renowned manufacturer, AGA Stoves, and chose a cast iron Little Wenlock. Before Alastair bought the stove, he decided to remove the existing fire surround and Victorian style cast iron inset fireplace (pictured right) in order to expose the original chimney opening. He then asked Essex-based HETAS installer, Village Fires, to survey the property and discuss the project’s requirements. With an output under 5kW, there was no requirement to insert additional ventilation. Here, we look at the process of installing the Little Wenlock from AGA Stoves using a flexible steel liner. Step one: The first step for Village Fires was to insert a flexible liner into the chimney. This required scaffolding to be erected, due to the position of the chimney and restricted access around the property. Step two: Once the liner had been fed through the chimney to the fireplace, a ceramic pot was added to the roof along with a cowl Step three: The flexible liner was trimmed to the correct length once it had been fed down the chimney Step four: Brackets for the register plate were fixed to the side of the chimney breast, ensuring they were higher than the brick arch and out of site Step five: The register plate was cut to a custom size, allowing the flexible liner and flue collar to be held in place Step six: The register plate was installed at the base of the opening, while the flexible liner was attached to the flue collar Step seven: A ventilation valve was also fitted in the register plate to allow the chimney to breathe Step eight: Village Fires laid a strong supporting cement base in preparation for the slate hearth. This allowed the floor to be levelled before the hearth was added, plus it also ensured the stove would be sat on a non-combustible material Step nine: The slate heart was laid and securely fixed onto the base, ensuring it was level Step ten: The AGA Little Wenlock was manoeuvred into the fireplace and the flue pipe was lined up with the collar in the register plate. On this installation, it was requested that the flue pipe came out from the top of the woodburner, although there is a rear fluing option if required Step 11: The stove was attached to the black WWW.HPMMAG.COM Step four 94 NOVEMBER 2015 HEATING & PLUMBING MONTHLY Step five enamelled flue, which in turn connected to the flue liner held in the register plate Step 12: The joint between the Little Wenlock stove and the enamel flue was sealed to ensure no flue gases or fumes escaped into the room Step 13: Once the stove and flue had been sealed, a smoke test was carried out using a smoke pellet. This checked the draw of the liner and ensured there was no smoke leakage into any room, as well as the loft space Step 14: The walls surrounding the fireplace were repaired and plastered to provide a smooth and clean finish, in keeping with the property’s character Step 15: To comply with the Building Regulations, a carbon monoxide monitor was fitted at the required height and location in the room Step 16: The AGA Little Wenlock stove was lit and tested, ensuring the stove reached operating temperature. Once this was completed, the installation was signed off by Village Fires as a HETAS approved installer, and certified accordingly. enquiry number 149 Step one Step 16: The AGA Wenlock is installed and signed off Step three Step seven Step two Step eight Step six Step 15 Step nine Step ten Step 11 Step 12 Step 13 Step 14
