In most cases, finding a boiler flue doesn’t involve a full-scale, Anneka Rice-style treasure hunt. Note 2: Most external manufacturers’ weather seals will require work to secure the chimney/flue to the building fabric, eg, sand and cement. Note 1: Where a terminal guard is required, it should be of a material able to withstand the corrosive properties of condensing products of combustion. If you already have a best combi boiler or regular boiler installed, a functional flue should be present. The sealant can withstand temperatures up to 300°C, which makes it the ideal solution to the problems outlined above. Where can you use high temperature silicone sealant?

In chimneys with more serious defects or unlined chimneys, HeatShield can be used with the CeCure Sleeve Relining System. The CeCure Sleeve is a thin profile, ceramic insulation, reinforced with stainless steel fabric that is sandwiched between two coats of HeatShield Cerfractory Flue Sealant. We install all the best boilers on the market and we only use Gas Safe registered heating engineers who know the boiler flue regulations off by heart as part of their yearly test. How can I ensure I get the best deal on a new boiler

Sealing around a boiler flue traditionally requires pointing with sand and cement. Removing any need for pointing, FlueSnug can be installed in less than five seconds and snuggly fits the 152mm core-drilled hole in the wall through which the boiler pipe and flue exits. FlueSnug can be used both inside and outside the property for the best finish and prevents heat escaping and acts as a barrier to drafts, damp, insects and pests.

BS 5440 Part 1: 2008 (1) does not state exactly what material is to be used to seal and secure. Where a manufacturer provides specific guidance on how to correctly seal and secure the chimney/flue, this guidance shall be followed. When fitting boiler flues, strict criteria are in place to ensure that combustion fumes and hazardous gases are released into the atmosphere safely. Kitchen and bathroom sealants hygienically seal the edges around your bath, sink and shower, with waterproof and mould resistant properties that allow for reliable use in wet areas. If you are NOT fitting a liner, but installing a clip-together chimney system (twin-wall), then you will secure your twin-wall adaptor to your vitreous (or to your stove if directly attached) using fire cement or fireproof webbing (webbing is so much neater and more effective).As you can probably gather from this brief description, boiler flues play a very important role, and this is why it’s always advisable to seek expert help if you think you might have a problem with your boiler flue. We recommend the same if you’ve moved home, as you won’t know what kind of condition the boiler flue is in. When fitting a chimney/flue, there are two distinct and separate requirements for the installer to consider: Where an inadequately sealed and/or secured chimney/flue is encountered and products of combustion have been confirmed as entering the property, then this is an Immediately Dangerous situation and appropriate actions must be taken to make the appliance safe (disconnection or rectification). Guidance is provided in the current Gas Industry Unsafe Situations Procedure (GIUSP) (3). Attach the appropriate warning label to the appliance and complete/issue a warning notice. This is not a nugget of information many of us store at the forefront of our minds, so don’t panic if you don’t know off the top of your head. Where an inadequately sealed and/or secured chimney/flue is encountered and the entry of products of combustion into the property has not been confirmed, then the installation should be risk assessed and the appropriate information given/action taken based on the level of risk identified.

A correctly installed weather collar will prevent ingress of weather and combustion products. In isolation, this Horizontal flues have a 300mm exit point. However, distances can rapidly increase to 2000mm roof windows that can be opened. Boiler flue extensions regulationsInstalling boiler flues just got easier: The PipeSnug team launches ‘FlueSnug’ – a boiler flue sealing collar Wood or gas burning stoves also have pipes, called stove pipes and chimney pipes. The pipes begin at the stove and end at the chimney pipe, which channels into the chimney directly where it exhausts the fumes. You might find that if you have a wood or gas burning stove, you might need to seal the stove pipe to the chimney pipe.

To seal small leaks and patch up areas around your home needing attention, we have a selection of repair wraps, tapes, adhesives and tools to complete the job. If you need to seal or repair surfaces that require heat resistance, our range of fire rated sealants are ideal for treating fireplaces, internal flue pipes and boilers. For hard to reach areas inside or outdoors, expanding foam is a flexible solution for sealing gaps around pipes and wires, while tough and long-lasting exterior sealants can be used on exterior pipework, roofing, guttering, glazing and frames. Chimney: should have pipes made from masonry or metal and in similar fashion, be sealed with aluminum flashing and high-temperature silicon caulking. Some chimneys/flues require screws in the joints to ensure they remain intact, however, others are push-fit. If there is doubt, the manufacturer of the appliance shall be consulted to confirm whether screws are required. Open and close the door on a cheap Chinese stove. Then open and close the door on a DG stove, Arada stoves, Woodford stoves, Hamlet stoves or Saltfire stoves. You’ll understand the difference.Use of sand and cement to seal the chimney to the fabric of the building would satisfy both points 1 and 2. The diagrams below show how sealing the chimney/flue to the fabric of the building secures the chimney/flue. When you’re sealing any kind of opening on a heating device (a furnace, water heater, or a chimney), you’ll need to pay special attention to the material you use to seal the flue as well as the building codes that regulate clearance. Without a boiler flue, there would be a risk of exhaust gases permeating the air in your home, which is definitely not advisable. Every new gas boiler installation requires a new boiler flue as per regulations.
