The NPE 240A Tankless Water Heater

What is included: ½” gas pipe capable up to 24 feet - Field convertible gas system - Ultra condensing efficiency - Dual stainless steel heat exchangers - Low NOx emissions (= 20ppm) - SCH 40, 2” venting up to 60 feet - Cascading capable

Features:

Ultra Condensing Efficiency
Navien‚s Condensing Technology offers the high efficiency.
Money and energy savings over tank type water heaters and traditional water heaters.
Two Stainless Steel Heat Exchangers
Provides longer life expectancy as they are highly resistant to corrosion and erosion compared to copper heat exchangers.
Reduces minerals deposits.
Low NOx Emissions (= 20ppm)
New metal fiber burner is designed to deliver a consistent air/gas mixture improving combustion efficiency.
Result in less acid rain and less green house effect.
Comply with SCAQMD 1146.2 strict NOx emissions standard.
2” PVC, CPVC, Polyprophylene Venting Up To 60’
2” venting option allows for a flue to be pulled through the existing vent.
3” vents can be used up to 150’ with standard 2” x 3” adapters.
Better Adaptability to Gas System
Utilizes Existing 1/2" Gas Line
The negative pressure gas valve and fan with dual venturi operation allows for better adaptability to low gas pressure applications.
Makes it possible for the NPE to be installed ½” gas lines up to 24’.
Field Convertible
NPE models allow for easy convertibility from NG to LP.

What you will receive includes Less Water Pressure Drop - Simple modular for water path minimizes water pressure drop - Modular design for water path make maintenance easier and service can be performed easily in the field - Intelligent Preheating Technology - Intelligent Preheating Technology - Recognizes hot water usage patterns to intelligently provide hot water when needed.
