The boiler heats up, life goes on, but something told me that everything is not so rosy, first of all, a mistake was found among many buyers of gas boilers, they all take with a reserve of power “just in case,” well, I, like everyone else, I took it with a reserve, with a reserve for hot water supply and frosts, i.e. It turned out that in warm weather outside, the Navien boiler continues to cycle, which is very unfortunate for him, and can lead to breakdown, first of all there may be breakdown ignition systems, since it constantly lights the boiler, and most often wears out, I don’t want it.

As an inquisitive researcher, with a stopwatch in my hands, I studied the cycles of the boiler in different modes of its operation, in warm weather, in cold weather, and decided to test the capabilities of the boiler at work depending on the temperature in the room, for this I selected the room mode in the boiler settings.

temperature setting.

At first everything was happy, the boiler obediently stood up, waiting for the set temperature to drop, but the joy was short-lived, cold was already creeping across the floor (the heat from the radiators, which cut off the cold air from my many windows, disappeared, and the house became not very comfortable, in the upper part the room where the control panel for the boiler hung, in which the temperature sensor is located, was in a warmer zone, we immediately understood that this was not suitable for us, at first we thought about hanging the remote control down, closer to the floor, but, firstly, this is inconvenient for control, secondly, it can be ruined by domestic cats, thirdly, the boiler may not turn off at all, trying to catch up with the temperature below, when it is already hot in the middle part of the room in height.

The room temperature test did not pass and was not suitable for me; at the same time I remembered the person who connected the gas, who advised that the boiler should not be turned on in this mode.

Time passed, but the cycles did not give me peace, and one day it occurred to me, while regularly observing the boiler, that the hysteresis (delta) in the turn-on-switch-off segment of the gas boiler was probably too small, and I would like the boiler to drive the coolant longer to a higher level. low CO temperature, but it was unclear how to do this, I certainly know how to program, but programming languages ​​are inappropriate for this boiler, and I don’t have equipment to connect to the “brains” of the boiler, and one day, purely by chance, I came across one well-known forum for a person who knows how to do this, and with the help of only one remote control, by entering

This is literally what needs to be done. to change the delta between boiler start-stop.

1. With the Navien boiler remote control turned off, press the + and - buttons for 5 seconds

mode setting

2. The number 8 or 9 or 10 will appear on the remote control display (for me)

3. Again, use the + or - buttons to change the value (this is delta) in the range from 2 to 20 (I set it to 12)

4. We wait 5 seconds, after which the boiler remote control goes out

5. Turn off the boiler by removing the plug from the socket for at least 10 seconds

6. Temperature difference value saved

Having done all this, I immediately realized the difference, the intervals between starts and stops of the boiler increased, although it only raised the delta by 2 degrees!, a useful thing engineering menu boiler Navien!

But, as it turns out, that’s not all it can do. Navien boiler engineering menu It turns out that the run-on time of the pump and blower after stopping the boiler can also be set!

Features of installing gas boilers Navien Ice and Deluxe

Since the weight of the device is 28-30 kg, the wall on which the device is mounted must be additionally strengthened (if there is a danger that the wall may not withstand such a load).

When installing the unit, you must use anchor bolt, which helps ensure reliable fastening of the boiler.

To avoid vibration, the boiler must be securely fixed to the wall (in order to prevent noise during operation of the device, you can use buffer panels, for example, rubber ones).

Install the Navien Ace/Deluxe double-circuit gas boiler strictly horizontally, and also maintain a distance of more than 60 cm on all sides for ease of repair and inspection.

Principles correct installation electrical wiring:

When preparing the 230V power supply, cables, and wiring connections, please comply with regional/local regulations in the area.

Before installing the device in areas with 230 V mains voltage, it is necessary to check the reliability of the wiring.

If any defects are found, please accept necessary measures to eliminate them.

Do not connect appliances other than the boiler to the power socket. The power socket must be located at a distance of at least 300 mm from the boiler.

Installation of a gas pipeline for a wall-mounted boiler Navien Ice/Deluxe

Diameter gas pipe connection to the device should be 15mm (1/2") or 20mm (3/4") depending on the model.

Gas pipes must be made of flexible metal that has been suitably tested for suitability.

Using liquefied gas There is no need to install a safety valve, but in this case it is necessary to install a gas valve.

When using liquefied gas, observe the following requirements.

The liquefied gas supply valve must also be a pressure regulator

To simultaneously supply gas from two or more cylinders, it is necessary to use a gas manifold.

When using 1 cylinder, the gas evaporation is insufficient, which leads to disruption of the normal operation of the boiler unit.

The boiler gas pipe is connected directly to the main gas pipeline;

It is prohibited to connect other devices to the gas pipeline.

Installation of a water supply system for a double-circuit boiler Navien Deluxe/Ace

The diameter of the water pipes is 15mm (1/2").

A tap must be installed at the point where the water pipe enters the boiler.

You may need to increase the pressure to operate the device. water supply, up to 0.3 bar (0.3 kgf/cm2)

Water must be supplied to the second floor at a pressure of at least 1 bar (1 kgf/cm2) (if the hot water tap is open).

If the device is used in an area with low water supply pressure, a pressure pump must be installed on the water pipe.

Before connecting the water pipe to the device, open the tap of the water pipe and bleed off excess air.

If the water pressure exceeds 8 bar (8 kgf/cm2), it is necessary to install a reducer that reduces the inlet water pressure.

Pipe Installation Guide

Hot water pipe installation work:

The hot water pipe diameter is 15mm (1/2").

The hot water pipe should be as short as possible.

Water supply and hot water pipes must be thermally insulated.

Should not be built complex system from pipelines.

To ensure proper drainage, the angle of inclination of the pipes must be at least 1/200 - 1/300 mm, that is, for 200 - 300 mm of the pipeline length, the slope is 1 mm below the horizon.

When connecting pipes, avoid the accumulation of air inside the pipes.

Operations for installing heating system pipes:

The diameter of the heating system pipes is 20mm (3/4").

The diameter of the water pipe must match the diameter of the circulation pipe.

The pipe should be as short, straight and solid as possible.

To provide correct drain water into the sewer, you need to connect the appropriate hose to the overflow hole.

When connecting pipes to a radiator, a manual or automatic air vent must be installed on the upper radiator manifold to prevent air from accumulating inside the radiator.

To prevent pipes from freezing, open areas pipes must be thermally insulated.

If it is necessary to install a pass-through manifold in a heating system for distributing the system to several heating circuits, the following conditions must be observed when selecting a manifold: a manifold with up to 5 outlets must have a diameter of at least 36 mm, a manifold with 6 outlets or more must have a diameter of at least 44 mm.

Fig.2. Navien Ace/Deluxe boiler piping arrangement

Basic precautions when installing pipes

All connections must be secured using couplings or fastening nuts.

To prevent freezing, all pipes and manifolds must be insulated.

Pipes must be made of materials that meet state or local standards.

Before connecting the heating and hot water pipes to the Navien Ace/Deluxe wall-mounted gas boiler, it is necessary to clean the pipe connections to remove chips and clean internal surfaces pipes from pollutants.

Well water should not be used to fill the system.

If it is impossible to avoid using water from a well, you should regularly clean the heating system pipes.

Contaminants contained inside pipes cause a decrease in the efficiency of the heating and hot water supply system, and also cause system failure.

It is necessary to completely bleed air from all appliances and pipes of the heating system.

Chimney

Chimneys/stacks for removing combustion products from natural draft boilers into the atmosphere must comply with certain standards and requirements.

The Navien Deluxe/Ace boiler with natural smoke exhaust is installed in a place with good ventilation.

Basic rules when selecting chimney elements:

Along its entire length, the diameter of the chimney should not be narrowed, but should be equal to or greater than the boiler outlet.

The chimney should be as vertical as possible. Horizontal sections are not desirable. If horizontal sections cannot be avoided, then their length should not exceed 2 m and an inspection must be provided on the section of the horizontal section for cleaning the chimney.

The cross-section of the chimney must be round (in rectangular and square chimneys, “dead, stagnant zones” appear, in which soot accumulates and, as a result, deterioration in draft).

It is preferable to make an insulated chimney and the best material for installing a chimney is stainless steel, since in such a chimney the condensation threshold is overcome much faster and, therefore, the chimney will last longer.

The end of the chimney should be a deflector.

In the lower part of the chimney (tee or support area), provide a plug or plug with a condensate drain if condensation is possible in the chimney or precipitation can enter the chimney.

Frost protection

If the Navien Ice/Deluxe wall-hung gas boiler is connected to pipes in which too much air has accumulated, when the frost protection function is turned on (after connecting the device to the network), the device may start to idle, the boiler may malfunction or the pump may overheat.

Therefore, before starting the frost protection function, it is necessary to bleed the air from the pipes and check the water level, that is, the pressure in the heating system.

Pipes must be completely thermally insulated.

When operating the boiler in areas with very low temperatures, the necessary measures should be taken to protect the pipes from freezing, that is, thermally insulate the open sections of the pipes with special insulating material (you can also water pipes near heating system pipes).

If the Navien Deluxe/Ice double-circuit gas boiler will not be used for a long time, you need to drain all the water from the system to prevent it from freezing, turn off the gas tap and disconnect the device from the power supply.

To protect the system from freezing, exposed areas must be thermally insulated with a special material at least 25mm thick (in areas with lower temperatures, thermal insulation material at least 50mm thick should be used).

Installing the Thermostat

Installation location:

The thermostat is installed on the wall in a heated room.

The distance from the floor to the thermostat should be at least 1.2 - 1.5 m.

The room in which the thermostat is installed must be well ventilated.

Thermostat installation method:

Securely connect the two wires coming from the Navien Ace/Deluxe boiler to the two wires coming from the thermostat

Use bolts to secure the thermostat mounting bracket to the wall.

When installing a thermostat in a room, observe necessary requirements installation instructions.

Do not use excessive force when connecting wires and tightening bolts.

If the wiring insulation is damaged or the wires are connected incorrectly, the thermostat may malfunction.

Under no circumstances connect directly to a 220V power source.

Do not hide wiring under the floor or in the walls of the room, and do not place it along the heating system pipes.
