Installation

To line or not to line?

Hello and welcome to our next blog, today I will be looking into a question that has been asked of us on an almost daily basis, which is often difficult to answer quickly. The question is “Should I line my chimney?” and the answer will hopefully become clearer below.

First and foremost it is important to note that there are multiple factors that will affect the necessity to line your chimney stack, and that there may be more than one option available to you based on the chimney type you have and the appliance you intend to install, whether it is a wood burning, multifuel or gas stove, or a simple open fire basket each installation will be different and will require a different approach.

In this blog I will be focusing on the most popular option, and the most common situation that our own Hetas engineers encounter whilst carrying out chimney surveys, which is the installation of a new stainless steel flexible chimney liner into an existing brick built chimney connecting directly onto a wood burning or multifuel stove.

Before committing to the purchase of your new stove it is advisable to organize a home survey to be carried out by a competent chimney engineer, this can be either a registered member of the National Association of Chimney Engineers (NACE) or preferably a Hetas registered engineer, who will also be capable of offering a complete installation survey for you should one be required.

If on inspection the chimney stack is found to contain a clay or pumice lining already in situ a smoke test should then be carried out to check for any potential leaks, if the chimney fails this test then provisions should be made to install a stainless steel flexible liner or if it is feasible to have the leak/s repaired this may also be an option.

It is sometimes possible for customers to carry out a basic inspection of the chimney themselves to establish whether a clay or pumice liner is present, to do this simply look up your chimney through your fireplace chamber opening using a torch and you should see either bare brick (unlined) or a smooth clay which is a clay chimney lining. (Please see images above for reference).

If after carrying out a smoke test your clay chimney liner does pass and is considered sound and suitable for use, then the installation of your new stove should be quite straight forward. Quite typically the only parts involved in the fitting process will be a length of vitreous enamelled flue pipe directly from the stove which is then cemented into the stove collar using a product called fire cement. From the top of the vitreous enamelled flue pipe you can then install either a product called a “clay pot adaptor” or a “sump adaptor”, which are both purpose built for the task and are made from stainless steel.

Once a tight seal has been made connecting either the clay pot adaptor or sump adaptor onto your clay pot chimney liner, you may then wish to install a solid fuel bird guard cowling. There are an abundance of different suitable cowls on the market, although the product we tend to recommend in our showroom and sales line is the stainless steel Wind Jammer cowl. This cowl is designed to not only prevent rain, birds and other vermin from entering the chimney, but it also aids the chimney draw to help prevent smoke passing back into the room through the stove.

The Wind Jammer cowl is available in a powder coated red finish as standard, and can be easily fitted onto a standard chimney pot using the supplied fixings using a screwdriver (no drilling is required).

Should a smoke test be carried out on the chimney which fails then a stainless steel flexible chimney liner will need to be installed. The process of lining the chimney is usually quite straightforward although it is advisable to employ the services of a qualified engineer to carry out the work as these engineers will also provide the relevant certification for the installation.

In our next Blog I will be continuing our discussion on chimney lining with a step by step “How To” installation guide, which I hope will be useful to anyone considering installing a chimney liner and stove themselves. This guide will also offer customers a better understanding of the work that their chosen competent installer is carrying out for those choosing to have a professional complete the stove installation.

To find your local Hetas registered installer please visit the official website at www.hetas.co.uk, you will then be able to click the “Find Installer” button and enter your postcode for a list of your closest qualified engineers, most of which should offer a free, no obligation home chimney survey.

No Chimney? No Problem.

Hello and welcome to another Simply Stoves Blog, this time I will be taking a look at the new Stovax Professional XQ twin walled flue system offered by the manufacturer Stovax Ltd, which is used when a wood burning or multifuel stove is required but no conventional chimney stack is present within the property.

Stovax launched their Professional XQ flue system in June 2011 with the promise of a high quality product obtainable exclusively through their network of trusted authorized distributors who were already suppliers of the sort after Stovax stoves range.

Simply Stoves have long been one of the leading suppliers of the Stovax stoves range in the UK, and the decision for us to change from another flue system brand to Professional XQ was an easy one based on Stovax reputation for superior craftsmanship, high quality materials, and designer-led aesthetics and technical innovation. I am pleased to report that with the Stovax professional flue system they have continued this high level of quality, backed up with the level of customer service and support to match.

Demand for twin wall flue systems have increased rapidly in recent years, which is in part due to a large proportion of new homes being void of a useable chimney or in some cases that no chimney is incorporated at all.

The beauty of using a Stovax Professional XQ flue system is that in most cases it is now possible to have a stove installed into almost any type of property safely and within the strict building regulations. The flue can be fed either external and then up through the outside wall, or alternatively internally through the building and out through the pitched or flat roof (see images below).

Each Stovax Professional XQ flue component features a Twist-Lock locking system which combined with the supplied locking bands offers a solid, weatherproof seal to each joint meaning it is suitable for internal and external applications.

Each flue part is made from high grade stainless steel, with a 316L inner wall for maximum corrosion resistance and a 304L highly polished outer skin for an attractive, clean and modern styling. The two layers are then insulated with a high density, 25mm ceramic mineral wool insulation, which effective allows the flue components to be installed with a minimal air gap of 5omm from any combustible material.

Unlike some other flue systems on the market, the inner insulation is protected by a formed stainless steel capping. This capping also allows for safe handling of the product and will help protect the installer from the risk of abrasions or cuts from sharp flue edges.

Some of the key reasons we favor the Stovax Professional XQ system above other flue brands is due to the abundance of decorative and supportive components available. These additional products are part of the reason that Stovax is at the forefront of design and technological advancement within the heating industry, and the innovation of the Professional XQ system is testament to the commitment of Stovax to constantly improve and develop their products.

Some of these key features include the following components;

Decorative Single to Twin Adaptor/Increaser

This adaptor is a decorative component designed to improve the connection between single skin enameled flue pipe and the Stovax Professional XQ Chimney System. The single skin enameled flue pipe can be inserted into the adaptor by up to 90mm to give a completely seamless join. For total flexibility, Stovax also offer an “increasing” version of this product for customers wishing to connect 125mm single skin vitreous flue to a 150mm Stovax Professional XQ system.

Decorative Ceiling Cover Plate

The Decorative Ceiling Cover plate is an innovative component designed to eradicate the issue of unsightly ventilated fire plates. The plate is made up of two separate parts with the second “decorative” section held into place using strong magnets which remove the need for any visible fixings visible within the room.

The ceiling cover plate is available in either a white or matt black powder coated finish as standard, with the white being a popular choice with customers wishing to match the ceiling colour, whereas the matt black is best suited when matching in with a fully powder coated matt black finish to compliment your stove.

Base Socket/Spigot Plate

This neat little component can be combined with a base and intermediate wall support plate and brackets to give an impressive amount of support to the Stovax Professional XQ flue system. It is usually used externally below a tee piece section when a solid support is required to support the flue system above. Combining the Base Socket/Spigot plate, Base wall support plate and bracket together allows up to 12m of Professional XQ chimney to be supported safely.

Decorative Vaulted Roof Support

Robust and secure, the Decorative Vaulted Roof Support can support the weight of up to 9m of your flue system. This component stabilizes your installation down to 6m below the support and up to 3m above it. However, if you do extend the flue system more than 3m vertically a Roof Bracing Kit can be fitted to offer more lateral support.

Roof Bracing Kit

The Stovax Roof Bracing Kit is an excellent addition to the Professional XQ range and is a practical and neat way to support the flue system as it extends through the roof tiles. This product is required if your flue system protrudes 2m or more through the roof to give a solid fixing via adjustable anchor poles with integrated anchor plates.

Expert Retailer Network

Stovax distribute their Professional XQ flue system through a series of authorized distributors, these experienced, independent retailers will be able to discuss your personal requirements on both the correct Stovax flue system and stove for your home. All members of the retail network offer a 10-year extended manufacturer backed warranty as standard on all Stovax professional XQ flue components, and an unrivalled after sales support.

Creative Colours

All external components in the Stovax Professional XQ range can be powder coated to virtually any colour of your choice (colours are matched to any colour on the RAL chart). This enables you to match any requirements that you have that may have been set by local planning authorities or to any specific aesthetic requirements you may have of your own. Stovax also offer a heat resistant textured matt black finish, which is strictly for use internally, and can be safely installed right down to your stove where the heat is at its most intense.

And so we come to the end of another Simply Stoves blog, if you are considering having a twin wall flue system installed then I hope that the details above may offer insight into some of the key reasons it is our flue system of choice here at Simply Stoves.
