This is a detailed estimate for the installation of a new B vent system for a fuel oil furnace. The vent system will be installed 4 feet above the roof line and will include a clean out tee. The estimate also includes the installation of a complete vent system that will go 4 feet above the roof line and will include a clean out tee. If you are happy with this estimate and would like to move forward with the installation, please sign and we will schedule it. Thank you, Ron.
