The main purpose of a central heating vent is to transfer the heated air from the main register into all the rooms of the house. Heating ducts are normally made of steel, and they are bound together with the help of screws. Unless such ducts are installed, the heated air will be constricted in one room, there shall be no efficient means to transfer the heat, and hence electricity costs would rise up significantly. Therefore, to ensure proper ventilation and heating in a room, ducts must be installed. This is a fairly simple process that requires only a few hours of your time. Follow the simple steps below for successful installation.

Step 1 – Locate Position and Cut Hole for Vent

Before you begin, put on the eye goggles and rubber gloves to ensure self-protection.

The first step in installing the vent is to figure out where exactly the vent will go. Consider the layout of the room. A heating boot should be present in the above room where the vent is being added. In most cases, the vent should be added onto the ceiling near the heating boot for hot air to be easily brought in.

Measure the size of the vent before cutting out a hole, and use a drill to cut it out. Then make a square around the holes.

Step 2 - Attach Grill and Connect to Heating Boot

Once the hole has been cut, fit the heating vent inside it and ensure that its properly seated. Next, ask for assistance to fasten the grill with screws on the vent in the room. On the ceiling, connect the vent to the heating boot using boot clips for now.

Step 3 – Use Flex and Connect Vent to Duct

Attach flex onto the vent from the ceiling, and place a collar on it. Measure the size of the hole, and cut it using a knife. Repeat this process for the other end of the flex. Now hook the flex over the collar cut out, and use tape to make sure it is properly tied together. Repeat this process for the other end of the flex. Finally, cover up the outer layer of the flex with mastic.

Step 4 – Cut Out Extra Flex

Cut off the excess flex with a knife; this should take care of the extra flex in both the inner and outer layer. By this point, your vent is ready to provide you a stream of hot air to keep your room comfortable.
