Why Skipping the Backdraft Damper for Your Bathroom Heater Can Lead to Serious I

The heated bathroom fan brings a different level of comfort to home life, but it is important to pay attention to installation details. Let's take a look at the consequences of not installing a backflow valve for the heated bathroom fan.

Consequences of Not Installing a Backflow Valve for the Heated Bathroom Fan

If a backflow valve is not installed, the exhaust function of the heated bathroom fan will be compromised, leading to an inability to expel humidity from the bathroom. When the fan is turned on, it relies on circulating indoor air. If the fan has an exhaust function, it will draw air from inside and expel it outside. Without a backflow valve, the exhaust will be negatively affected.

Important Considerations for Installing a Heated Bathroom Fan

1. The installation of the main unit of the heated bathroom fan is not a trivial matter; it should be installed neatly without tilting. Otherwise, a collapse could pose significant dangers. Additionally, it is crucial to tighten the expansion screws used for installation.

2. The opening size in the bathroom ceiling should be in accordance with the specified requirements and should not exceed the sample by more than 5mm. If the space is small, care should be taken during cutting; the gap around the fan after installation should not be greater than 3mm.

3. If the bathroom space is larger than 2.5m, it is advisable to install a support bracket. If the homeowner insists on not using a bracket, they should be made aware that not using a support at a higher installation height can present safety hazards.

4. Special care should be taken regarding the expansion screws for the fan; it is best to avoid any situation where the fan is merely suspended from the ceiling, as this may lead to safety risks.

5. For wall-mounted heated bathroom fans, it is necessary to maintain a distance of about 1.7m between the fan and the floor. Any other specific requirements should be clearly communicated.

6. During the installation of the fan, it is essential to ensure that the cover plate is properly adhered, avoiding situations where the cover plate compresses the unit, as this could cause unnecessary complications.

In summary：we have discussed the consequences of not installing a backflow valve for the heated bathroom fan, as well as key points to consider during installation. It is crucial to get the installation right to avoid safety hazards and ensure proper functionality in the future.
