Navien Ace gas boiler series

The Ice (Ace) series of Navien boilers are a range of gas double-circuit units produced by KyungDong NAVIEN, a South Korean company.

In addition to heating the house, they also supply hot water for it. One characteristic of Navien equipment is its technological and climatic specialization in Russian conditions.

It is possible to operate at low gas and water pressures, and the system is resistant to abrupt pressure changes.

Furthermore, there’s a protective system that makes up to 30% of the voltage drops in the power supply network.

Furthermore, the company’s pricing strategy makes Navien boilers roughly twice as expensive as equivalent-power European equipment. Users greatly value these benefits, and demand for Navien units is steady and increasing over time.

A boiler that is operated incorrectly or in challenging conditions can be quickly disabled. This is the outcome of inadequate attention and a failure to take the necessary steps to establish ideal operating conditions rather than a result of subpar assembly.

What models and what power are there

The following models were part of the Ace series:

• Ace Atmo
• Ace Turbo
• Ace Turbo Coaxial

Due to their open (atmospheric) combustion chambers, the Atmo models required a powerful smoke extraction system.

Their efficiency was significantly lower, but by installing a copper heat exchanger—which is more productive than stainless steel units—this was successfully made up for.

The closed combustion chamber design and turbocharging, which involved supplying fresh air through a special fan to increase combustion efficiency and draft in the smoke removal system, set apart the Turbo model range.

To eliminate the gases, a European or Korean (coaxial) chimney type was employed.

The first option consists of a chimney and two independent pipes, one for the air supply.

A chimney is installed both inside and outside the air supply pipeline in a coaxial chimney system, also known as a "pipe in the pipe" system.

Each model had a power output of 10, 13, 16, 20, 24, 30 kW, etc.D. The most widely used models, the 16k and 24K, are best suited for private home maintenance.

Specifications

With the exception of the ATMO series, practically all models share the same technical specs; the unit’s power is the only difference.

In line with the heated area, 13 kW boilers can heat 130 m2, 24 kW can heat 240 m2, and t.D.

The primary characteristics of the boilers in the ACE series should be condensed into the following table for ease of consideration:

Parameter	Ace	Ace Coaxial	Ace Deluxe	Ace atmo
Type of boiler	Gas wall double -circuit
Type of combustion chamber	Closed			Open
Efficiency	91.2 %			86 %
Thermal power of the boiler along OV	9-16 kW
The material of the primary heat exchanger	Stainless steel			Copper
Coolant temperature in the heating system	40°-80°
DHW temperature	30°-60°
Control type	Electronic
Mains voltage	Single phase, 230 V, 50 Hz
Weight	28 kg			26 kg
Case dimensions	440x695x265 mm			430x720x340 mm

The kind of combustion chamber and all associated design elements are the only reasons for the performance differences.

It should be mentioned that the 16 kW models have a significant margin of safety because they are essentially a 24 kW model’s analogue with fewer software features.

Advantages and disadvantages

The following are some benefits of Navien Ace boilers:

• Optimal combination of price and quality.
• Environmentally friendly process.
• Simplicity and convenience of adjustment and configuration of operating modes.
• Adaptation to Russian conditions, the ability to operate at unstable gas pressure, water, power supply voltage.
• Simultaneous provision of heating and domestic hot water.
• Long service life without service checks.

The following are Navien Ace boiler drawbacks:

• Dependence on availability of electricity, gas and water.
• High noise level.
• Only original spare parts are suitable for repairs.
• Instability of the structure to hard water.

The majority of the flaws are related to design elements rather than mistakes or poor assembly.

They come standard with practically all gas boilers, no matter who makes them. If your water is too hard, you should use electromagnetic softeners or other suitable equipment to prevent the buildup of lime deposits.

Where is it used?

The Navien Ace series of gas double-circuit boilers is intended to arrange the hot water and heating supply for nearby offices or residential buildings.

Despite the fact that these units can be installed in any room, this restricts their range of applications. The primary objective is to align the serviced area with the equipment’s capabilities and the availability of all required resources, including water (a heat carrier), gas, and electricity.

Apart from the area, the room volume must also be considered, as it might be excessively large for this particular Navien boiler model. The maximum volume that the system can have while still operating normally is indicated on the product passport.

What is included in the package

The following components are included in the unit units:

• Heat exchangers (primary and secondary, the primary can be made of copper or stainless steel, the secondary – only from stainless steel).
• Remote control panel.
• Circulation pump.
• Expansion tank.
• Three-way valve.
• Safety valve.
• Draft sensor.
• Automatic air vent.
• Connecting pipelines, other structural elements.

The boilers come with mounting brackets and other extra parts in addition to the main components.

Device

The primary tubular heat exchanger of Navien Ace boilers, which is connected to the combustion chamber, is the key component of their design.

A chimney that is joined to or combined with an air supply pipe is located at the top. An eight-liter expansion tank with a three-way valve and circulation pump installed is located on the left side of the housing.

It guarantees that hot water and coolant flow through the system. After going via the heat exchanger, the coolant is heated to a high degree.

After that, the cold flow is combined with the system temperature-targeting three-way valve. Following that, the flow is diverted from the boiler and directed toward convectors, radiators, and other heating equipment. P.

With the goal of giving professionals and homeowners alike a thorough understanding of how the Navien Ace functions in actual situations, this article also offers helpful advice on how to maximize performance and improve maintenance.

Connection instructions

The boiler is easy to install; all you have to do is hang the unit on the wall and install anchor bolts.

To reduce noise, it is advised to place elastic gaskets between the body and the wall. Never install the equipment on flimsy or weak structures, such as plasterboard partitions or other surfaces of a similar nature.

A sturdy brick or concrete wall that can sustain the boiler’s weight—roughly thirty kilograms—is required.

The proper pipes should be connected to communications. Vigilant observation of connection tightness and compliance is required.

Gas pipe connections should receive the majority of attention. Use a soap solution to check all connections for leaks.

Separate pipeline connections are used if there is a common chimney: the smoke channel is connected to the house’s common chimney, and the air channel is led through the wall out into the street.

The installation of coaxial chimneys is much easier and more convenient because they are led outside through the wall.

Basic malfunctions and their solutions

Navien boiler malfunctions are typically identified separately and shown on the display along with the relevant code. A notification about an issue that has emerged is triggered by a signal from one or more sensors.

The most typical errors are:

• 02. Lack/insufficient amount of water in the system. The issue can be resolved by recharging the system or replacing the flow sensor.
• 03. No flame in the combustion chamber. Indicates problems with the ignition system, or lack of gas.
• 05-06. Open circuit or short circuit of the oxygen sensor.
