Procedure for installing a wall trim step-by-step:

  1. The choice of installation site and the preparation of the wall for placing the Navien boiler is performed according to the project. Since the mass of the structure is 25-35 kg, the wall on which the device will be mounted should be capital or additionally strengthened to withstand the load.
  2. Install an anchor bolt for reliable fasteners of the structure.
  3. The thermal insulation and a buffer panel, for example, rubber are installed on the wall, to prevent vibration of the boiler Navien Deluxe and the noise background.
  4. The Navien unit is installed strictly in a horizontal position, in compliance with a distance of at least 60 cm from all sides for repair and maintenance.
  5. Make a connection to an electric line with a voltage of 230 V. The socket for connecting the device should be individual and located at a distance of not more than 300 mm from the body. Boiler equipment must be grounded.
  6. Connect the unit to the gas pipeline directly. Any other gas equipment should not be connected to this site. The installation site must be stiffly fixed to prevent independent dismantling of parts.
  7. Contact the water supply with a diameter of 15 mm or 1/2 ". At the point of entry of cold water, a shut-off tap is installed into the unit. Water pressure should be in the range from 1 kgf/cm2 to 6 kgf/cm2. Otherwise, it will be necessary to apply methods of increasing/decreasing pressure in the water supply.
  8. Carry out a strapping unit with heating systems. When connecting pipes to the battery at the upper part, a manual or automatic air vent is installed to remove air from the network.
  9. All areas of compounds are fixed using mounting couplings or mounting nuts.
  10. Carry out thermal insulation of pipes and collectors.
  11. Install a thermostat on the wall in a heated room, with a distance from the floor 1.5 m.

We connect the chimney

The installation of a Navien boiler with a natural chimney system takes place in a space that has dependable supply ventilation and three different air circulation options.

The chimney section ought to line up with the Navien gas boiler’s smoke pipe. The boiler’s technical documentation must adhere to the manufacturer’s specified scheme for chimneys and their geometric dimensions.

The primary prerequisites for installing chimney system components are:

  1. Throughout the length of the chimney, its diameter should be without excesses equal or more than the smoke pipe of the unit.
  2. The chimney is arranged vertically. If horizontal areas are present according to the scheme, then their length should be no more than 2 m. An audit is installed on this site to clean the smoke system.
  3. The section of the chimney is performed round, because in rectangular and square structures there are stagnant areas in which soot accumulates, traction is reduced.
  4. The metal of the chimney is stainless steel.
  5. A deflector is installed on the chimney.
  6. In the lower part in the tee or support zone, a plug with a condensate carrier is installed.

Installation of the floor boiler Navien

Because the floor gas boiler is a potentially dangerous item, it can only be installed in a specific room—the project’s furnace—per the most recent SNiP regulations. Since the user does not have permission from the gas service to operate the unit, it is impossible to ignore these requirements.

There has to be a dependable ventilation system in the furnace. Up to 150 kW Navien gas boilers can be installed on any floor, while larger units should only be placed in the basement or on the ground floor.

Installing them in bathrooms and residential buildings is prohibited. Cavities or niches should not exist in the furnace to prevent the buildup of combustion products and the creation of explosive mixtures.

Underneath the gas unit is a sturdy cement base. The building’s structural components near the unit need to be shielded from the possibility of fire.

Thermal insulation is typically applied with a roofing sheet placed over a refractory gasket, such as an asbestos sheet thicker than 3 mm.

Around the whole perimeter, the protective structure should extend at least 100 mm beyond the boiler’s dimensions. There should be a minimum of 100 mm between the unit’s wall and the heat-insulated walls.

The device provides at least 1.0 m of clear space in front for servicing. An iron sheet measuring one square meter is placed over the area in front of the Navien boiler.

Auxiliary equipment and intra-house engineering networks, such as a circulation pump, fan, security group, drainage line, sub-file line, heating and hot water system, gas pipeline, and chimney system, are connected to the boiler after it has been installed.

The manufacturer’s factory’s technical materials and boiler room design documentation both list binding schemes. A specialized organization with the authorization to carry out these kinds of operations performs installation work. Gorgaz specialists do maintenance on gas equipment.

Connecting the chimney

In addition to ensuring the house’s hygienic and fire safety, the chimney helps the unit operate efficiently in accordance with efficiency standards.

The boiler equipment manufacturer installs the gas transmit dimensions in the furnace chamber in order to create the necessary discharge for air leaks at the combustion mouth. Prior to installation, the chimney’s exit location is established so that it can be integrated with a boiler chimney pipe.

The minimum chimney diameter for boiler units with an open top-bearing chamber and a maximum capacity of 35 kW is 140 mm; for more productive units, the diameter should be greater at 160 mm.

Closed Navien boilers have a coaxial type of type, which is specified by the manufacturer in technical documentation or is included in the device supply.

Installing the condensate airler and deflector, as well as isolating the boiler at the points where it passes through the building’s structures, are crucial when installing the boiler and its chimneous system.

After securing the chimney’s component parts into a cohesive whole, the boiler fireplace’s natural traction is examined by holding a lit match up to the smalle’s viewing window.
