Revised Bid Sheet

The owner is requesting a separate quote as an option to replace the existing Reznor furnace Model SCE200-6-S-MV Type Natural Gas CFM 3650 at 730 IN  460 Volts 3 phase 60 Hz.

The objective is to replace the existing furnace with a more energy efficient model that utilizes a Horizontal vent that can extend through the wall rather than venting vertically through the roof.

Provide a cost to cap the roof vents in the furnace room, leaving the existing duct work in place.
