Have you ever heard of a pellet stove with a suction cup outlet? This device has a low installation cost, low environmental impact and high efficiency. In addition, it’s been quite popular for a number of years. But, its installation is quite complex and requires skills in the field.
What you need to know before installing a pellet stove
In general, there are three types of installation of a pellet stove with venting. But before doing anything, you must take into account the safety instructions: observe the safety distances (especially for combustible materials) and take into account the air supply of the stove.
Parameters to be taken into account
To ensure a successful and safe installation of the appliance, it is imperative to determine certain parameters:
Find the ideal location
The stove must generally be installed on a solid and resistant support because the appliance is often heavy (between 70 and 250 kg). The place where you have to put it should have at least a volume of 20 or 30 m³, a surface large enough to allow the proper cooling of the device. On the other hand, it is totally inadvisable to put it under a beam or in a niche.
You should also know that the stove should never be placed too close to combustible material. If your floor is also combustible (such as a laminate floor), put a steel plate between it and the stove. The same applies to the flue pipe: it must be located more than 8 cm from a combustible wall.
Placing the air inlet
This can be direct or indirect. In the first case, the appliance is connected directly to the outside air via a flexible pipe of 50 to 80 mm in diameter and 5 m in length. For its part, the indirect solution is to design a hole of 80 mm, or an opening of more than 50 cm ².
The installation of the pellet stove with suction outlet
There are several ways to install a pellet stove with suction outlet:
1 – The installation in zone 1
This type of installation is also called standard installation. The pellet stove with venting can give more flexibility in the installation. The chimney flue should generally exceed 40 cm from the ridge.
2 – The installation in zone 2 or vertical venting
This is a vertical flue pipe installation: in principle, the flue pipe exits below the ridge (at roof level). This technique is often used in new buildings, as it avoids drilling into the waterproof shell of the house.
3 – Installation in zone 3 or horizontal suction cup
This method considerably reduces the installation costs and limits the amount of fume extraction, because the flue pipe allows the fumes to be extracted from the façade. The installation in zone 3 also simplifies the installation of the pellet stove. However, it is not suitable for new buildings.
Never try to install a wood stove in a suction cup (in zone 1 and 2), because it is impossible. Indeed, this device is not equipped with a smoke extractor motor. In addition, it must have a high flue to facilitate the removal of combustion residues. However, you can proceed with the installation in zone 1.
