How to Install a Pellet Stove: A DIY Guide 2026

When you buy a pellet stove, the retailer often offers installation and first ignition services. However, it's good to know how the job is done to understand what preparations are needed. So, how do you install a pellet stove on your own?

To start, the pellet stove needs a connection to the electrical grid, so you'll need a free power outlet as close as possible. It must also be placed against a perimeter wall where you can open a hole for the flue gas outlet, unless there is already a suitable chimney flue that isn't connected to other heating appliances on different floors.

Time Required: 30 Minutes

Step 1: Remove Any Transport Supports

To ensure stability during transport, the stove is fixed to the pallet with screws inserted from below. You need to remove these to free the stove. In some cases, the screw holes are used to screw in the support feet. Before proceeding, check the firebox compartment: it may contain, besides the instruction manual, some components that need to be assembled during installation.

Step 2: Create a Hole for the Flue Gas Outlet

Before making the hole for the flue gas outlet in the wall or ceiling, verify that no electrical cables or pipes are running in that spot. Use the end of the pipe as a template to trace the circumference on the wall. Open the hole with a hole saw of the same diameter. For safety, consider adding lighting to brighten your workspace.

Step 3: Mount the T-Fitting

Mount the T-fitting on the rear flue gas outlet, pointing the end meant to collect soot downward.

Step 4: Complete the Flue Gas Line

Complete the flue gas line by inserting pipe sections one into the other. If they are not airtight, seal the joints with high-temperature silicone and cover them with aluminum tape.

Step 5: Position the Stove in Its Final Location

Now you can place the stove in its final position and insert the pipe into the wall hole. But first, assess whether you need to stiffen the exhaust pipe with clamps that grip along its vertical run, and if so, fix them to the wall with expansion anchors beforehand. A work surface can be handy for organizing your tools during this step.

Step 6: Connect the Stove to the Electrical Grid and Verify

Connect the stove to the electrical grid and verify it operates correctly. For added comfort, consider pairing your stove with outdoor heating solutions for seamless warmth.
