The Installation Process

A step-by-step description of a standard stove installations.

Installing a wood burning stove into an existing fireplace and chimney.

Stove in existing chimney

For the most common type of installation the stove is fitted into an existing fireplace and the chimney is lined.

Prepare the fireplace

The fireplace is prepared. Before the stove is installed, the fireplace may have to be opened up or enlarged, a gas fire or a surround removed. The interior bricks may need cleaning and pointing or rendering. The fireplace opening may require beading and plastering to make good.

Laying a hearth

A hearth is laid. Its function is to protect the floor from any embers that may fall out of the stove. It also creates a boundary to stop any combustible materials such as a carpet from getting too near the stove. Most of the hearths we lay are slate, but there are many options.


The chimney is swept and the stack inspected. If there is no chimney pot a new one must be mortared in place. This is a good opportunity to check the general condition of the stack and the roof.

Chimney liner

A stainless steel flexible liner is pulled down the chimney, with fingers crossed so that it doesn’t get stuck. It is not necessary to line a chimney if a smoke pressure test has proven that it does not leak. As a smoke test is a two man operation that requires going up to the chimney top and is by no means infallible, we always recommend lining as the small extra cost is worth the peace of mind.

Insulating the flue is an option at this point. We only think it is necessary for certain appliances and if the chimney stack is in an exterior and therefore cold position. If the flue is to be insulated then pouring vermiculite flakes down the chimney is often the best option.
A chimney cowl

A weatherproof cowl is attached to the liner and sits on the chimney pot sealing off the chimney from water ingress and supporting the weight of the liner. The cowl has a bird mesh to stop birds entering the flue.

Register plate

The register plate is cut to size and fitted. This is made from galvanised metal sheeting and closes off the chimney opening just above the arch or lintel of the fireplace. It stops any debris that may fall down the chimney from entering the room. It also stops the air heated by the stove from being lost up the chimney.

The stove pipe is inserted into the stove and connected to the liner by means of an adaptor.
Testing the stove

The installation is tested and the stove lit. We do this with the customer so we can explain how best to operate the stove and highlight the safety considerations.

Installing a wood burning stove when there is no existing chimney.

Wood burning

When there is no existing chimney or it cannot be used, a factory made insulated chimney pipe is used and the stove sits on a hearth in the room.

The stove is placed on a free standing hearth that meets building requirements.

A length of stove pipe connects the stove to the insulated stainless steel chimney, which can either run up inside the house and through the roof, or through the wall behind the stove and up the outside of the building.

A hole is made in the roof and in any in-between floors if the chimney goes up inside the house.

Roof supports are attached to the insulated pipe and to the rafters to support the chimney’s weight and make it stable.

A flashing unit is used on the exterior of the roof and the whole system is sealed to keep it weatherproof.

A rain cowl is fixed atop the chimney to keep the rain out and a storm collar is put in place to protect the flashing unit.

The insulated chimney pipe can run up the outside of the building if it makes the installation easier, in which case:

A hole is made in the outside wall through which the chimney goes through at 45 degrees and then runs vertically up the outside of the wall finishing at a suitable height above the roof.
