Viessmann Vitodens 100/200 Combi PlusBus Pre-Plumbing Jig | ZK04919

Description

The Viessmann PlusBus Combi Boiler Surface Mounting Pre-Plumbing Jig is the first-fix hydraulic and gas connection frame for Vitodens 100 and 200 PlusBus combi boilers, allowing plumbers to complete pipework and pressure testing before the boiler itself arrives on site.

Fitting directly to the wall ahead of the boiler installation, the jig carries all the valves, gauges and safety devices the combi boiler needs, so the appliance simply hangs onto a pre-tested, pre-plumbed connection point.

🛈

Please Note: This jig is specifically for Vitodens 100 and 200 PlusBus combi boilers. It is not interchangeable with the equivalent System boiler jig, which uses a different valve configuration for the additional cylinder flow and return connections.

Complete pre-plumbing solution

Supplies all the valves and fittings needed for heating flow/return, gas and DHW connections ahead of boiler installation.

Integral safety shut-off

The gas shut-off valve includes an integral thermally activated safety shut-off device as standard.

Boiler drain & fill valve included

Simplifies future servicing with a dedicated drain and fill point built into the jig.

Pressure gauge and air vent fitted

A pressure gauge and air vent valve are included, giving the installer immediate visibility of system pressure during commissioning.

Surface mounting for exposed pipework

Designed for surface mounting installations where pipework runs are visible rather than chased into the wall.

Compatible with mixer sub-mounting kit

Works alongside the Vitodens 200-W Combi Boiler Sub-Mounting Kit with mixer for multi-zone heating circuit setups.

Vitodens 200-W Combi Boiler Sub-Mounting Kit with mixer

Does this jig work with both Vitodens 100 and 200 combi boilers?

Yes, it's specified for PlusBus Vitodens 100 and 200 combi boilers sharing the same connection standard.

Can I use this jig for a system boiler instead of a combi?

No. System boilers use a separate pre-plumbing jig with additional cylinder flow and return connections — this jig is combi-specific.

Does the jig include the gas isolation valve?

Yes, a gas shut-off valve with an integral thermally activated safety shut-off valve is included as standard.

Can this jig support a sub-mounting mixer kit for a second heating zone?

Yes, it's designed to be compatible with the Vitodens 200-W Combi Boiler Sub-Mounting Kit with mixer, which sits below the boiler for two-zone systems.
