yourself and others at risk.
The gas valve is installed for regulating the correct amount of air to the air volume
into a gas condensing boiler.
Note: The chapter Commissioningin this manual and the Installation manual of the
heating system used must be observed!
Danger!
All work in connection with the installation must only be carried out by an approved
gas installer!
Any accessories used must comply with current technical rules and must be ap-
proved by the manufacturer for use with the gasvalve. Only use original spare

these instructions voids the appliance/device approval.
