Boiler insulation can be installed following the steps outlined in this how-to article. The process of installing a boiler can be a huge job for a do-it-yourselfer. If you are determined to install any type of boiler, you may need to make sure that you are licensed for the project if required by your community code. If this is not a concern, proceed with the remainder of this article to learn how to install a boiler.

Step 1: Prepare the Location for the Boiler

The first step in installing a boiler is to prepare the location for the boiler. Look for all of the needed connections needed for the installation. Water and gas lines as well as electrical circuits need to be close to the location that the boiler is being installed. If you do not have these connections near by plan on how your going to feed water and gas to the boiler.

You need to make sure that there is no combustible liquids or solids where the boiler is going to be installed as well.

Step 2: Prepare the Boiler for Installation

Remove the boiler from its shipping carton. The boiler will be bolted down with a screw that will need to be removed. Once removed, slide the boiler out of the wood pallet. Take everything out of the store boxes including all your zone valves, circulator pumps and all other boiler dressing accessories that you have purchased for the boiler installation.

Step 3: Dress The Boiler and Install the Water Piping

Add the boiler accessories such as the circulator pump, flo-checks, riser nipple and other accessories. A forced hot water system requires a feed and return on each boiler. You will need to pipe the feed and the return lines. 

Step 4: Installing the Venting and Flu Pipe

The boiler will have to be properly vented for safety. The type of boiler you have (i.e. combi, powervent, hydronic) will determine the type of venting you will need. A traditional gas fired forced hot water boiler would be vented with a standard smoke pipe. If you have an on demand combi boiler or a tankless boiler that has a power-vent, the venting will be completely different. 

Step 5: Connect the Gas to the Boiler

Depending on what type of gas you have in the building or home will determine how you hook up the gas lines. If you have a propane unit you can connect to the regulator and then to the gas valve by following your local plumbing code and using the allowed types of pipe. In many states copper lines are allowed to be flared and used for delivery of propane gas to the unit.

Be sure that you take all necessary safety precautions when connecting the gas to the boiler and that you also test the connection thoroughly after installation. This will detect any potential leaks and prevent an explosion from occurring.
