Product detailed description
Buderus GB172/072 Mounting Kit
Buderus belongs to the Bosch Thermotechnik group and has been a synonym for reliable and energy-efficient heating and hot water technology for decades. 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 GB172/072 mounting kit is original Buderus accessory intended for the mechanical mounting and hydraulic connection of the GB172 and GB072 condensing boiler to the wall-mounted heating, hot water and gas distribution system. The boiler itself cannot be hung and connected without a supporting mounting plate, connecting elements and a shut-off valve on the gas supply — and these are exactly the components included in the kit.
By using the original mounting kit instead of an improvised solution made of various parts, you ensure that the connection spacings exactly match the boiler's connection ports, that the joints are tight, and that the whole assembly meets the manufacturer's requirements for warranty-compliant installation.
What's included in the set
- U-MA mounting plate (7738112657), 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 the supporting element on which the boiler is hung on the wall — it ensures correct dimensions and mounting strength. The connecting accessories link the boiler outlets with the heating and hot water distribution system. The GA-BS gas ball valve serves as a shut-off element on the gas supply just 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 kit is intended for Buderus GB172 and GB072 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 supply, and must therefore 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 kit necessary, or can I put together the connection from other parts?
The mounting kit is designed exactly for this 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 loss of warranty.
Does the kit 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 kit?
Installation and commissioning must be carried out by an authorized service technician or certified installer qualified to work with gas and heating equipment, in accordance with the manufacturer's installation instructions.
Is the kit suitable for an older installation where a different boiler was previously installed?
The mounting plate and connecting elements are designed for the dimensions and connection points of the specific Buderus series. When reconstructing an older piping system, we recommend having the situation assessed by an installer on site.
Does the kit price include the gas hose or gas supply?
The kit includes a gas ball valve for connection to the gas distribution system; the gas pipeline itself and its inspection are part of the construction preparation carried out by the installer.
What if part of the kit is missing or damaged on delivery?
Please contact us immediately upon receiving the shipment — we handle any damage or incompleteness as part of the claims process with the carrier as well as 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 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 a service logbook for the appliance. If you have any questions about choosing the right kit for your specific boiler type and power output, feel free to contact us — we will be happy to help.
