HomeMy WebLinkAboutB16-0498 plans approved.pdf Existing floor plan at 2249 Chamonix Lane Unit 1 Vail,Colorado for replacement of old boiler located near the east
wall with a direct vent 94%HTP EFTC-140W wall hung combination boiler/water heater UL listed on the east wall.
The existing water heater will be disconnected but will remain in place for emergency water heating if necessary.
Plans comply with 2015 IBC and 2015 IMC requirements.
Installation complies with National Fuel Gas Code that allows 20-25%free area allowance for wooden louvers.
Using only an upper combustion vent the standard practice is 1 square inch of combustion air is needed for every
3000 input BTU.
The HTP EFTC-140W is a direct vent system that will result in less combustion air being required than the existing
boiler.Adequate combustion air is present for the remaining two water heaters.
