Vaillant distance frame 105 mm for ecoTEC plus/pro for VIH Q 75 mounted side by side
Code: 0020021856Product detailed description
Vaillant distance frame 105 mm – mounting spacer for ecoTEC plus/pro with side-mounted VIH Q 75 cylinder
The Vaillant distance frame 105 mm (order number 0020021856) is an original mounting accessory for Vaillant ecoTEC plus and ecoTEC pro wall-hung condensing boilers, designed specifically for installations where a VIH Q 75 wall-hung domestic hot water cylinder (a 75-litre cylinder mounted next to the boiler on a shared mounting bracket, not underneath the boiler) is installed alongside the boiler. The frame creates the necessary gap between the back of the boiler and the room wall, which is required to fit the connecting pipes and fittings leading to the cylinder mounted next to it.
What exactly the frame is for
With standard boiler mounting directly on the wall (without a cylinder, or with the cylinder placed underneath the boiler), the standard clearance provided by the boiler's own design is sufficient. However, if a configuration with the VIH Q 75 cylinder mounted next to the boiler (not underneath it) is chosen, a distance frame with a thickness of 105 mm must be inserted between the boiler and the wall. This frame:
- Creates space for routing connecting pipework (heating water, hot and cold water) between the boiler and the side-mounted cylinder without the need to chase grooves into the wall
- Allows for a symmetrical, visually clean arrangement of the boiler and cylinder side by side on a shared wall
- Simplifies future servicing, as the connecting pipework remains accessible behind the boiler's removable cover rather than being embedded in the wall
Technical design
- Frame thickness (distance from wall): 105 mm
- Designed for Vaillant ecoTEC plus and ecoTEC pro boilers (compatibility applies to model ranges that support side-mounted installation of the VIH Q 75 cylinder)
- Compatible with the VIH Q 75 wall-hung domestic hot water cylinder (75 litres), mounted next to the boiler
- Metal construction with mounting holes matching the standard mounting bracket of ecoTEC boilers
- Includes the necessary fastening material for securing the frame between the boiler and the wall
When you need this frame
This specific distance frame is required exclusively for the configuration where the VIH Q 75 domestic hot water cylinder is mounted next to the boiler on a shared wall (typically in smaller utility rooms, kitchen units with concealed appliances, or where there is no suitable space underneath the boiler for the cylinder). For the alternative configuration, where the cylinder is placed directly underneath the boiler, other types of mounting accessories are used (for example insulating aesthetic covers for under-boiler cylinder mounting), not this side distance frame. Similarly, if a different type or volume of cylinder is installed instead of the VIH Q 75, compatibility of the specific mounting accessory should be verified with a technician or directly in the Vaillant catalogue.
Installation
- The frame is fitted onto the shared mounting bracket together with the boiler, between the back of the boiler and the room wall
- Before installation, it is necessary to verify that both the wall and the mounting bracket can bear the combined weight of the boiler, frame and cylinder when fully filled with water
- Connecting pipes (heating water between the boiler and cylinder, cold and hot domestic water) are routed through the space created by the frame between the boiler and the wall
- Once all connections are made, the boiler cover is fitted, which also conceals the distance frame itself
- Installation should always be carried out by a qualified technician authorised to install gas appliances, as the connection involves gas, heating water and domestic water pipework
Compatibility
The 105 mm distance frame is designed for Vaillant ecoTEC plus and ecoTEC pro condensing boilers in a configuration with a side-mounted VIH Q 75 wall-hung cylinder. Before ordering, we recommend verifying the exact boiler model and planned cylinder configuration directly with a dealer or technician, as different model ranges and cylinder volumes may require different mounting accessories (for example a different type of frame for newer boilers with IoniDetect technology, or a completely different solution for mounting the cylinder underneath the boiler instead of next to it).
Maintenance
The distance frame itself, as a passive metal structural element, requires no maintenance. However, we recommend checking the following during regular boiler servicing:
- The security of the mounting of the boiler, frame and cylinder on the mounting bracket
- The tightness of the connecting pipework routed through the space created by the frame
- Any signs of corrosion on the metal structure of the frame, particularly in more humid environments
Why choose original Vaillant accessories
Using the original distance frame guarantees precise dimensional and mechanical compatibility with the specific boiler and cylinder model, including the position of mounting holes matching the standard mounting bracket. Improvised or non-original solutions (such as self-made spacer elements) may cause problems with mounting strength or insufficient space for routing pipework, which represents a safety risk with heavy combinations such as a boiler plus a filled cylinder.
Related accessories for boilers and cylinders
Besides this distance frame, atria.sk also offers other related mounting accessories for Vaillant boilers and cylinders – for example the 92 mm distance frame for side connection of newer IoniDetect boilers, insulating aesthetic covers for under-boiler cylinder mounting, a condensate drain siphon, or a circulation pump for VIH R uniSTOR cylinders. When planning a complete boiler and cylinder installation, we recommend verifying which specific components your chosen model and configuration require, to avoid having to purchase missing parts additionally during installation.
Typical use case in practice
Imagine an apartment or smaller family house where a section of wall in the kitchen or a utility niche is reserved for the boiler and the domestic hot water cylinder side by side – for example due to limited ceiling height that does not allow mounting the cylinder underneath the boiler. In this case, the 105 mm distance frame is used to ensure the correct distance of the boiler from the wall for routing the connecting pipework to the side-mounted VIH Q 75 cylinder, while the resulting installation looks like one compact, visually clean unit.
Frequently asked questions
- Is this frame also needed when mounting the cylinder underneath the boiler? No, this specific frame is intended exclusively for the configuration with the VIH Q 75 cylinder mounted next to the boiler. Different accessories (such as an insulating aesthetic cover) are used when mounting the cylinder underneath the boiler.
- Is the frame compatible with cylinders other than the VIH Q 75? The frame is specified by the manufacturer for use with the VIH Q 75. For other cylinder volumes or types, we recommend verifying compatibility with a technician before ordering.
- Does the package include fastening material? Yes, the required fastening material for securing the frame between the boiler and the wall is included.
- Can I carry out the installation myself? Installation of the boiler, cylinder and connecting pipework (gas, water) should always be carried out by a qualified, authorised technician, as it involves work on gas and pressurised water systems.
- Is the frame visible after installation is complete? No, once all connections are made, the boiler cover is fitted, which also conceals the frame itself – the resulting installation is visually clean.
- Does using the frame affect the warranty on the boiler or cylinder? No, correct installation of original accessories according to the manufacturer's instructions does not affect the warranty; on the contrary, it is one of the conditions for its proper recognition in the event of a claim.
- What is the warranty on this product? We provide a standard statutory warranty of 2 years from the date of sale on the 105 mm distance frame.
Why side-mounting the cylinder is sometimes the only solution
Mounting the domestic hot water cylinder directly underneath the boiler is the preferred solution in most apartments and family houses due to lower wall width requirements and simpler connection. However, there are several situations where this configuration is not possible or suitable: insufficient ceiling height in the utility room (the boiler plus cylinder underneath it would exceed the available height), the need to keep the space underneath the boiler free for other purposes (such as a washing machine or cabinet), or architectural constraints when renovating an older apartment where a wider but lower wall section is available. In these cases, side-mounting the VIH Q 75 cylinder next to the boiler is a practical alternative directly supported by this distance frame.
Impact on the overall layout of the utility room
When planning a side-mounted installation, it is important to take into account in advance the total width that the boiler together with the VIH Q 75 cylinder will occupy on the wall, including the necessary handling and service clearances on the sides of the assembly. While the 105 mm distance frame addresses the depth clearance from the wall required for routing the pipework, the actual layout of the boiler and cylinder side by side (width of the assembly) needs to be planned already at the installation preparation stage, ideally in cooperation with a technician who will also take into account the position of the gas supply, electrical connection and flue outlet.
Comparison of side and under-boiler cylinder mounting
| Configuration | Height requirement | Width requirement | Required accessories |
|---|---|---|---|
| Cylinder underneath the boiler | higher (boiler + cylinder stacked) | lower (same width as the boiler) | insulating aesthetic cover for under-boiler mounting |
| Cylinder next to the boiler (this offer) | lower (only the height of the boiler/cylinder) | higher (boiler + cylinder side by side) | 105 mm distance frame |
This table serves as a guide when deciding between the two mounting variants; the final decision should always take into account the specific layout options of the given room.
Relation to IoniDetect technology
Newer Vaillant ecoTEC boilers equipped with IoniDetect technology (advanced flame monitoring using the ionisation principle with automatic combustion adjustment) may in some cases have different mounting accessory requirements compared to older model ranges – for example a different type of distance frame with a different thickness (e.g. 92 mm instead of 105 mm). Before ordering, we therefore always recommend verifying the exact type and generation of your boiler in order to choose the correct mounting accessory variant.
Importance of correct clearance for servicing
Besides the initial installation of the pipework, the correct clearance created by the distance frame also plays an important role in future servicing of the system. Sufficient space behind the boiler allows the service technician easier access to the connecting fittings and any shut-off valves without having to remove the entire boiler-cylinder assembly from the wall, which reduces the time required for routine maintenance and any repairs.
Practical experience with side configuration installation
Installation companies that carry out installations with the side-mounted VIH Q 75 cylinder confirm that the most common mistake when the correct distance frame is missing is insufficient space for later handling of connecting hoses and fittings, which only becomes apparent during the first service intervention, when the technician finds that the location cannot be comfortably accessed. Using the original, precisely dimensioned 105 mm frame from the manufacturer prevents this problem already at the installation stage, since the frame's dimensions are designed directly in cooperation with the development of the boiler and cylinder themselves.
Impact on the boiler and cylinder warranty
Using original Vaillant accessories, including this distance frame, installed according to the manufacturer's instructions by a qualified technician, has no negative impact on the warranty terms of the boiler or cylinder. On the contrary, following the prescribed installation procedure, including the use of the correct type of mounting accessory, is one of the conditions for the recognition of any claim under the warranty provided by the manufacturer for the boiler or cylinder.
Recommendations when ordering related accessories
When ordering the 105 mm distance frame, we also recommend checking whether you have all the other accessories needed for a complete installation of the boiler plus side-mounted cylinder assembly – for example connecting pipes between the boiler and cylinder, a hot water temperature sensor in the cylinder, or possibly a circulation pump if you plan to increase the comfort of hot water supply to more distant outlets in the apartment or house. Ordering all the necessary accessories in advance saves the installation company time and avoids unnecessary additional orders and delays during the actual installation on site.
Summary
The 105 mm distance frame is a simple yet essential mounting component for the specific configuration of installing a Vaillant ecoTEC boiler with a VIH Q 75 cylinder mounted next to the boiler. It provides the necessary space for routing connecting pipework, contributes to a visually clean final appearance of the installation, and also facilitates future servicing thanks to better access to the fittings behind the boiler. As an original part directly from the manufacturer, it guarantees precise dimensional and mechanical compatibility with the specific boiler and cylinder model, which cannot be fully guaranteed with improvised or non-original solutions.
