How to make a DX Series gas fireplace “Fan in Room” installation quiet.

By design, DX Series fireplaces are whisper quiet home heating appliances. However, in certain installations, the fan might be positioned differently to our Escea specifications and could emit some sound through the walls or air vents.

In this blog, we will discuss the options you have to make sure your DX Series gas heater installation is just as peaceful as it should be.

When the fan is placed in an open ceiling cavity or underfloor, there will typically be enough distance from the fireplace to the fan to eradicate any chance of sound. The key is in how far the ducting runs are between the fireplace and the fan and having adequate goose neck bends.

But when the fan has to be installed in the chimney cavity in the same room as the fireplace or the fan to vent distances are very short, then special attention has to be made to sound attenuation.

Most commonly, issues with sound occur because there are limited options for placing the fan. If this is the case, then there are few things to note to make sure your DX Series gas fire is always quiet.

  1. Baffles/insulation break up sound

By surrounding the fan with baffles or insulation (pink batts, batts, sound proof materials) you can reduce or in some cases eliminate any noise.

  1. Goose neck the ducting

By curving the ducting into goose necks, you will break up the sound waves coming from the fan inside the duct. The sound waves travel in straight lines, so if the ducting curves around a lot then it will help make sure the sound does not travel out of the vents.

With our DX Series fireplace ducting system, there is no issue with overheating, so in small spaces, there is no fire danger if the ducting is touching itself.

However, do take care not to restrict the airflow the goose necks as you don’t want them to be so bent or crammed into a small space.

These goose necks need to be placed between the heat exchanger and the fan and between the fan and the splitter. The goose necks from the fan to the splitter are very important.

  1. Consider using sound gib/dry wall materials if you have to install the DX fan in a confined

Just remember – If you do install a DX Series gas fire, make sure there is always an access panel for the duct fan and power flue fan. This is for regular service and maintenance reasons.
