how to install furnace humidifier

Are you looking for a way to improve the air quality in your home? If so, installing a furnace humidifier may be the solution for you. Furnace humidifiers help add moisture to the air, which can help reduce respiratory problems and allergies. This blog post will teach you how to install a furnace humidifier in your home. We will provide step-by-step instructions that are easy to follow!

Mark and Cut A Hole In the Return

The manufacturers supply templates and instructions for this operation, including a template and a marker to sketch out a hole in which you need to fit the home humidifier.

Drill the outline at the corners first. Then, the hole is cut out using aircraft snips according to the manufacturer’s instructions. The mounting plate should be in place before you drill the screw hole, and then it is fastened to a mounting plate using sheet metal screws.

Mark and Cut Outline of the Humidistat

The humidistat is typically installed to the cold air returned at least one foot above the humidifier, according to the manufacturer’s instructions. After cutting out the hole, attach the low voltage and install the thermostat with the tin screws that come with it.

Install the Electrical for the Humidifier

You’re now ready to move on to the electrical. The circuit is quite basic, and the humidifier should include a transformer.

1. The high voltage from the electronic air cleaner and control board must be wired together. Once the fan goes on, it will activate your humidifier. After connecting the high voltage, you use your thermostat to power the solenoid valve.

2. A word on electrical wiring: it’s easy, but it may be challenging to figure out. For assistance, see the instruction manual. You’ll find some helpful diagrams for completing this section of the challenge.

3. If necessary, now is the time to install the humidistat. The home’s thermostat, in our scenario, already can manage humidity. If your thermostat isn’t capable of doing so, you’ll need to install the humidistat that comes with it. The wiring should be explained in detail in the instruction manual.

Connect the transformer to a 120-volt power supply, and link the digital humidistat controller’s wires to the furnace. Excluding the green wire, which controls the fan, all thermostat wires will remain the same. It’s a good idea to add an exterior temperature sensor if your humidifier kit has one: it will help adjust humidity more precisely.

Install The Bypass Vent (Optional)

Use the template to trace the hole for a 6″ bypass pipe if your humidifier needs one. Cut the vent hole with aircraft snips after drilling a starting hole. Using sheet metal screws, secure a circular collar in the hole.

Cut the vent pipe to length after you’ve measured the distance between the collar and humidifier air input. Secure the assembly to the humidifier air intake and the collar by installing elbows on both ends of the vent pipe.

Connect Water Line to The Humidifier

If local regulations allow for direct tapping of a water line, you must install a saddle valve on the water line. Also, connect a line to the humidifier, followed by the compression fitting to make it quick.

There’s a chance that the saddle valve cannot switch off the water pipes and connect the at-fitting. Then you may install a bypass line in the HVAC system to produce water vapour.

Test the Furnace Humidifier

After the installation, it’s time to test your work! Check for leaks around the connections, and ensure that the water line is secure. Then, turn on the humidifier and set it to your desired humidity level.

If everything looks good and there are no leaks, congratulations—you’ve successfully installed a furnace humidifier!

Conclusion

A furnace humidifier is a great way to improve the air quality in your home, and it’s not as difficult to install as you might think. With this guide, you should be able to install one in no time.
