2. Detailed steps for installing wall-mounted boiler chimney
1.Determine the installation location: According to national standards, the horizontal distance between the chimney outlet and doors, windows, and vents should be ≥ 1.5 meters, and the vertical distance should be ≥ 0.5 meters.
2.Select pipe type:
| Type | Applicable scenarios | Service life |
|---|---|---|
| Single layer aluminum tube | Ordinary residence | 5-8 years |
| Stainless steel composite pipe | high-rise building | 10-15 years |
| Ceramic inner bile duct | Highly corrosive environment | More than 15 years |
3.Install tilt control: The chimney should be kept at an inclination angle of 1-3° toward the outdoors to ensure smooth discharge of condensed water.
4.Connection sealing treatment: Use high temperature resistant sealant (can withstand over 300℃) to seal all interfaces.
3. The five issues that users are most concerned about recently
1.Can the chimney pass through the exterior wall insulation?
Yes, but you need to use special insulation sleeves and keep a distance of more than 10cm from the insulation material.
2.What is the chimney length limit?
The total length of the chimney of an ordinary wall-mounted boiler shall not exceed 3 meters, and the allowable length shall be reduced by 0.5 meters for each additional elbow.
3.Winter antifreeze measures
During the recent cold wave weather, it is recommended to install an insulation cover for the exposed smoke pipe to prevent condensation water from freezing and clogging.
4.How to check air tightness after installation?
You can use the smoke test method: light the incense and place it at the interface and observe the direction of the smoke.
5.Common installation errors
Maintenance cases in the past 10 days show that 45% of the problems are caused by the backflow of condensed water caused by the inverted installation of the chimney.
4. Professional installation suggestions
1. According to the latest GB25034-2020 standard, a rainproof cap and insect-proof net must be installed at the end of the chimney.
2. Warning from many recent accidents: Do not connect the chimney to a public flue, as this will cause carbon monoxide to be injected back.
3. It is recommended to install CO alarms. Recent data shows that installing alarms can reduce the accident rate by 78%.
4. After the construction is completed, flue gas analysis and testing must be carried out to ensure that the CO content is <100ppm.
5. Material purchasing guide
| Accessories | Brand recommendation | reference price |
|---|---|---|
| Stainless steel smoke pipe | Macro/Wanhe | 80-120 yuan/meter |
| sealant | Dow Corning | 45-60 yuan/piece |
| rain hat | Haier | 35-50 yuan |
Summary:Correct chimney installation is related to the safety of the whole family. Based on recent hotspot feedback, it is recommended to give priority to stainless steel materials, strictly control the inclination angle, and regularly check the condition of the flue. If you do not have professional knowledge, be sure to contact a professional installer for operation.
