Product detailed description
Buderus GB122 Mounting Set
Buderus is part of the Bosch Thermotechnik group and has for decades been synonymous with reliable and energy-efficient heating and hot water technology. German build quality, precise connection dimensions and long-term availability of spare parts and accessories are among the main reasons why Buderus boilers and system components are a popular choice among installers and investors across Europe.
The GB122 mounting set is genuine Buderus accessory intended for the mechanical mounting and hydraulic connection of the GB122 condensing boiler to the wall-mounted heating, hot water and gas piping. The boiler itself cannot be hung and connected without a supporting mounting plate, connecting elements and a gas shut-off valve — and these are exactly the components included in the set.
By using the original mounting set instead of an improvised solution made of various parts, you ensure that the connection spacing exactly matches the boiler's connection ports, that the joints are tight, and that the whole assembly meets the manufacturer's requirements for warranty installation.
What's included in the set
- U-MA mounting plate (7738112657), 1 pc
- Condens 2300 connecting accessories (7736901403), 1 pc
- GA-BS gas valve, straight 1/2 (7738112222), 1 pc
- Drain funnel with siphon (7719000763), 1 pc
What each component is for
The mounting plate (U-MA) is a supporting element on which the boiler is hung on the wall — it ensures correct dimensions and mounting strength. The connecting accessories link the boiler's outlets with the heating and hot water piping. The GA-BS gas ball valve serves as a shut-off element on the gas supply right before the boiler, which is a mandatory part of every gas connection for both safety and inspection reasons. The drain funnel with siphon safely and hygienically discharges condensate and any drained water from the system into the sewage system.
Compatibility
The set is designed for Buderus GB122 series condensing boilers. Before ordering, we recommend verifying the exact designation and power variant of your boiler, or contacting us to confirm compatibility.
Installation
Installation requires connection to the gas, water and heating piping and therefore must be carried out by a certified installer or an authorized Buderus service technician, including inspection of the gas connection in accordance with applicable legislation. Incorrect installation may affect operational safety as well as warranty recognition.
Frequently asked questions
Is the mounting set necessary, or can I solve the connection with other parts?
The mounting set is designed exactly for the given type of Buderus boiler and guarantees correct hydraulic and mechanical connection. Using non-original or incompatible parts can lead to leaks, reduced boiler lifespan and voiding of the warranty.
Does the set also include the boiler itself?
No. This is exclusively mounting and connection accessories. The Buderus condensing boiler itself must be ordered separately.
Who can install the set?
Installation and commissioning must be carried out by an authorized service technician or a certified installer qualified to work with gas and heating equipment, in accordance with the manufacturer's installation manual.
Is the set suitable for an older installation where a different boiler was previously used?
The mounting plate and connecting elements are designed for the dimensions and connection points of the specific Buderus series. For reconstruction of an older piping system, we recommend having the situation assessed by an installer on site.
Does the set price include the gas hose or gas supply?
The set includes a gas ball valve for connecting to the gas piping; the gas pipe itself and its inspection are part of the construction preparation carried out by the installer.
What if part of the set is missing or damaged upon delivery?
Contact us immediately after receiving the shipment; we resolve damage or incompleteness both through the carrier's claims process and directly with you.
Warranty and service
The components of the set are covered by the standard warranty period provided by the manufacturer Bosch Thermotechnik GmbH / Buderus and by the seller in accordance with the applicable terms and conditions. To claim the full warranty on both the boiler and accessories, we recommend having the installation and commissioning carried out by an authorized Buderus service partner and keeping the equipment's service log. If you have any questions about choosing the right set for your specific boiler type and output, feel free to contact us — we will be happy to help.
