Measure the bottom of your pellet stove with the measuring tape and add 12 inches to the result. The base should extend out 6 inches from beneath the stove, so if your stove is 24 inches by 30 inches, the base you build needs to be 30 inches by 36 inches.
Nail the 2-by-4s together to form a frame for the pellet stove base.
Choose the location for your pellet stove. Place the wooden frame on the floor in that spot.
Remove any carpeting or linoleum that is inside the frame. They will be a fire hazard if you leave them in place.
Create a cement mix according to the manufacturer’s directions. Pour the mix into the frame, filling it up to the top of the frame.
Float a wooden smoother over the top of the cement, rubbing away any ridges and creating a smooth, even surface.
Wait for the cement base to cure completely before installing the pellet stove on top of it. Depending on humidity and temperature in your area, this can take between two to four days.
Remove the frame from around the dry cement base.
