Ultra Condensing Efficiency

• Navien’s Condensing Technology offers 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)

• The new metal fiber burner is designed to deliver a consistent air/gas mixture, improving combustion efficiency.
• This results in less acid rain and less greenhouse 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.

Utilizes Existing 1/2″ Gas Line

• The negative pressure gas valve and fan with dual venturi operation allow 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

• NCB models allow for easy convertibility from NG to LP.

Where Technology Meets Ecology, Combination Boiler

• The ideal solution for customers who need both domestic hot water and a space heating application.
• Heats water when needed, making it environmentally sound as well as cost-efficient.

Hydronic Heating Benefits

• Clean: little chance to cause dust or lower humidity because there is no air movement.
• Silent: offers silent heating because no blowers are needed for forced circulation.
• Comfort: keeps floors warm but indoor air fresh, making people feel warm and comfortable.
• Coverage: radiant heat makes heating from floor to ceiling possible.
• Economical: radiant heat in the floors can transmit warmth throughout the house hours after turning off the heater.

Automatic Water Filling System

• Automatically fills water into space heating pipes when the unit senses a water shortage.

Powerful Anti-Freeze Feature
