Steps for How to Install a Combination Boiler/Water Heater:

2. Run new gas, electrical, and plumbing lines to the plywood panel.
3. Screw the metal mounting brackets to the plywood panel, then hang the combination heater onto the brackets.
4. Drill two 4-inch-diameter holes through the house wall for the exhaust vent and air intake vent. Be sure the air intake is above the snow line, and that the exhaust vent is 12 inches from a window and 12 inches from the air intake.
5. Use PVC pipe and fittings to create the exhaust and air intake vents. Run the piping from the boiler through the exterior wall.
