New Jersey Uniform Construction Code requires a chimney certification for replacement of a hot water heater, furnace, or boiler.
For oil to gas conversions, or for oil to oil and gas to gas replacements:
Prior to installing a new furnace, boiler or hot water heater, the homeowner must make sure that chimney is in safe condition, and that the chimney certification is signed and given to the local code enforcement office.
By signing the chimney certification, our chimney experts certify that chimney/vent is free and clear of obstruction, and is substantially clean of residue from its previous use serving an oil appliance. We further certify that the chimney/vent is appropriately lined and sized for the appliance being installed.
