• 🪟 Window with a window — glazing area from 0.03 m² per 1 m³ of room volume.
• 🚪 Door width ≥80cm with a gap at the bottom or a grille for air flow.
• 🔥 Walls and floor made of non-flammable materials (or protected by metal sheets).

If the boiler is installed in kitchen (for models with power up to 35 kW), the requirements are softer, but mandatory:

• 🍳 Ceiling height ≥2.5 m.
• 🪠 Availability of hood and ventilation duct.
• 🔌 Socket for connecting the boiler (if the model is energy-dependent).

For legal installation you will need the following documents:

1. Technical specifications (TS) from the gas supply organization.
2. Gasification project (developed by a licensed company).
3. Chimney acceptance certificate (if the boiler has an open combustion chamber).
4. Service agreement with gas utility.

⚠️ Attention: Without a project and approval, connection to the gas pipeline illegal. Fines for unauthorized installation reach 50,000 rubles (Article 7.19 of the Code of Administrative Offenses of the Russian Federation).

2. Model selection and equipment: what you need to buy besides the boiler

Ruler Geyser Prestige PM includes models with power from 10 to 40 kW, with an open or closed combustion chamber. To choose the best option, focus on:

• 🏠 Heated area (1 kW ≈ 10 m² with a ceiling height of 2.7 m).
• 🌡️ Climate zone (for Siberia the power reserve is + 20–30%).
• 💧 Necessity of hot water supply (single-circuit or double-circuit models).

In addition to the boiler, you will need to purchase:

Component	Purpose	Approximate prices (2026)
Coaxial chimney	For turbocharged models (closed chamber)	5 000–12 000 ₽
Chimney pipe (stainless steel)	For atmospheric models (open chamber)	3,000–8,000 ₽/m
Gas filter	Protection against gas impurities	1 500–3 000 ₽
Expansion tank	System pressure compensation	2 000–6 000 ₽
Wall bracket	Boiler mounting	800–2 500 ₽

⚠️ Attention: For models Prestige PM with open combustion chamber prohibited use flexible corrugated chimneys - only rigid stainless steel pipes with a thickness of ≥0.5 mm.

If the boiler will operate in conjunction with heated floors, you will additionally need:

• 🔄 Circulation pump (if not built into the model).
• 📊 Collector unit for distribution of coolant.

3. Installing the boiler on the wall: step-by-step instructions

Installation begins with marking and securing the boiler. For models Geyser Prestige PM The following rules apply:

• 📏 Distance from walls - at least 20 cm (for maintenance).
• ⚖️ Height from floor — 80–160 cm (for ease of access to the control panel).
• 🚫 Prohibited install shelves or cabinets above the boiler.

Step-by-step algorithm:

1. Mark the wall for the brackets (use a level!).
2. Drill holes and secure brackets anchor bolts (diameter ≥10 mm).
3. Hang the boiler on the brackets and check the horizontal position with a building level.
4. Secure the boiler to the brackets using the fixing screws (included in the kit).

For models with coaxial chimney:

• 🔧 Cut a hole in the wall with a diameter 5-10 mm larger than the diameter of the chimney.
• 🛠️ Install protective cover (comes complete with chimney).
• 🔄 Connect the chimney to the boiler, making sure the connection is tight (use heat resistant sealant).

4. Connection to the heating system and water supply

The connection diagram depends on the type of system (open/closed) and the number of circuits. For Geyser Prestige PM a typical harness includes:

• 🔹 Supply pipeline (from the boiler to the radiators).
• 🔹 Return pipeline (from radiators to boiler).
• 🔹 Expansion tank (compensates for thermal expansion of water).
• 🔹 Circulation pump (if not built in).
• 🔹 Security group (pressure gauge, safety valve, air vent).

Connection order:

1. Install coarse filter on the return line (the arrow on the body must coincide with the direction of flow!).
2. Connect the heating pipes to the corresponding boiler connections (supply/return). Use American women for ease of dismantling.
3. If the boiler is double-circuit, connect cold water to the DHW inlet pipe (usually marked with a blue ring).
4. Install shut-off valves to all supply pipes for emergency shutdown.

⚠️ Attention: For systems with antifreeze check the compatibility of the boiler seal material (in the instructions for Prestige PM it is stated that only propylene glycol in concentrations up to 30%).

Typical mistakes when tying:

• ❌Usage rubber hoses instead of metal-plastic or polypropylene.
• ❌ Absence bypass (a bypass for the coolant when the boiler is turned off).
• ❌ Incorrect pipe slope (must be ≥5 mm per 1 m for gravity systems).

What happens if you mix up the supply and return?

If the boiler is connected incorrectly Prestige PM may overheat as the temperature sensor reads data from the return line. This leads to emergency shutdowns and reduced service life of the heat exchanger.

5. Gas connection: rules and safety measures

This is the most crucial stage, which should only be performed by a certified specialist. Independent connection to the gas pipeline punishable by a fine and cancellation of the boiler warranty.

Gas pipeline requirements:

• 🔧 Pipes - only steel or copper (flexible hoses >2 m long are prohibited).
• 🔒 All connections must be hermetically sealed (checked with soap solution).
• 🛠️ Install gas tap in front of the boiler for emergency shutdown.
• 📏 The minimum distance from the boiler to the gas pipe is 10 cm.

Connection order:

1. The specialist connects the gas pipe of the boiler to the pipe through dielectric coupling (protection against stray currents).
2. Checks the tightness of connections pressure gauge (pressure drop is not allowed).
3. Installs gas filter (if it is not included in the boiler kit).
4. Conducts crimping system (pressure 0.1 MPa for 10 minutes).

⚠️ Attention: After connecting to the gas, be sure to check commissioning work with filling out the report in the boiler passport. Without this document, the manufacturer's warranty doesn't work.

6. First start and setup of the boiler

Before starting for the first time, complete the following steps:

• 💧 Fill the heating system water (pressure 1–1.5 bar).
• 🔍 Check for air in radiators (bleed through Mayevsky taps).
• 📋 Make surethat all the valves on the pipes are open.

Startup instructions:

1. Connect the boiler to the electrical network (if the model is volatile).
2. Click the button Start/Stop (or Heating mode on the panel).
3. Set the desired heating temperature (it is recommended to start with 60°C).
4. Wait for the burner to ignite automatically (the flame indication appears on the display).

If the boiler does not start, check:

• ⚡ Availability of voltage in the outlet (220 V ±10%).
• 🔥 Gas pressure (must be ≥13 mbar for natural gas).
• 💨 No blockages in the chimney (checked visually or using a mirror).

To configure operating modes:

• 📊 Click Menu and select User Settings.
• 🔧 Install Max. DHW temperature (55-60°C recommended to prevent burns).
• ⏱️ Customize Timer (if time programming is required).

7. Common mistakes and how to avoid them

Even if the instructions are followed, owners often encounter problems due to minor miscalculations. Let's look at the most common ones:

Error	Consequences	How to avoid
Incorrect chimney slope	Backdraft, carbon monoxide poisoning	Slope ≥3° towards the street, check draft with an anemometer
No return filter	Heat exchanger clogged, pump failure	Install a magnetic or mesh filter
Using low-quality antifreeze	Corrosion of seals, leaks	Only propylene glycol with additive package
Leaking gas connections	Gas leak, explosion	Check with soap solution, pressure testing
Lack of grounding	Electronic breakdowns, malfunctions	Connect to ground loop (resistance ≤4 Ohm)

⚠️ Attention: If the boiler Prestige PM after startup it often shuts down with an error E1 (no flame), the cause may be:

• 🔥 Pollution ignition electrode (clean with sandpaper).
• 💨 Insufficient traction (check the chimney).
• ⚡ Crashes in electronics (needs diagnostics by a service center).

8. Maintenance and care: how to extend the life of the boiler

The manufacturer recommends maintenance Geyser Prestige PM at least once a year. Basic procedures:

• 🧹 Cleaning the heat exchanger from scale (use special solutions, for example, Detex).
• 🔥 Burner check and ignition electrodes (soot removal).
• 🔧 Automation diagnostics (test of draft, flame, pressure sensors).
• 💧 Flushing the system heating (every 2–3 years).

For self-care:

1. Check back monthly system pressure (should be 1–1.5 bar).
2. Clean once a quarter coarse filter on the return line.
3. Follow flame color (should be blue, an orange tint indicates incomplete combustion of the gas).

⚠️ Attention: If the boiler Prestige PM operated on liquefied gas, replacement of jets (injectors) should only be carried out by a certified technician. Incorrect selection of jets leads to excessive gas consumption and burner damage.
