Furnace Installation Instructions

Here are some of the instructions for your furnace installation

Finding proper placement

Your new furnace will have to sit on a pad to lessen any unwanted noise that might come when it functions. Nevertheless, it should be at least 2” inches off the floor which would allow the air under it and keep the bottom from rusting out. If this is a fresh furnace install, before even placing the furnace, you will have to keep in mind that your furnace can make extra noise. Basements, closets, and attics are all good places to place your furnace.

Connecting ductwork

Before you set your HVAC unit in any cabinet, you will have to make sure that you know where the return air duct is going to be connected to the unit. In case the hole is not already cut to match your cabinet size, then you can also perform this part yourself. The whole unit will need to drain any condensate; hence, the furnace must have a slight slope that will allow the drainage. You must place the HVAC unit in the cabinet area and connect the ductwork system properly. The ductwork should be connected with the help of a metal foil tape or duct sealant. You should not use duct tape as it can melt or fray and eventually disintegrate.

Venting pipes for drainage

The next step would be to connect the vent pipes. There must be PVC pipes for an inlet and exhaust. You must always make sure that these pipes are clean so the glue will stick to the pipes and stay connected no matter what comes its way. Make sure that the pipes have a 1/4” tilt per four feet so it will drain.

Connecting drain pipes

As stated earlier using a ¾” PVC pipe or hose, connect the condensate drain from the furnace to the floor drain or drain pan.

Preparing the gas supply

In order to install a gas furnace, the next step would be to connect the gas supply. You will have to the shutoff valve and a drip leg, or T valve, right outside the furnace on the gas line. You must spray a gas leak detection solution in order to check for any gas leaks. Do not light in case you see any bubbles. In case you are not experienced with any gas heater installations, it is always recommended to get professional help as this can be dangerous if you do it by yourself.

Finalizing electrical connections

Now you will have to connect the electrical connections. First of all, you must always make sure that you know which is low voltage and which is line voltage. The line voltage must always run from the furnace to the disconnect switch, which must be located approximately three feet from the unit.

Checking the unit

In the end, you will have to start the furnace turn the HEAT on, and let it cycle to make sure that it is working properly. You will have to check the outlet air temperature and the return air temperature so that you can always make sure that it matches the manufacturer’s specifications. This is a crucial step in installing a furnace.

Furnace Filter Installation

Whether you believe it or not, there are many right ways and many wrong ways in order to insert an HVAC furnace filter. In case a filter is not properly installed, it can affect the furnace’s efficiency and cost you a lot of your money to get it fixed. It is very important for you to routinely observe your air filters so that you can prevent them from becoming obstructed with dirt, dust, or debris, and so they continue filtering the air you and your family breathes. Clean filters allow for better indoor air quality and improved energy efficiency.
