regulations for public gas supply).

7.17 Checking for leaks during operation

▶ With the burner running, use a foaming leak detecting agent to test all
joints along the entire burner gas supply route, e.g.:
• Blanking plug in testing point for gas supply dynamic pressure
• Unions, etc.
The agent must be approved for gas leak testing.
CAUTION: Risk of system damage due to short-circuits.
▶ Before testing for leaks, cover the areas at risk, e.g.
the internal water pressure sensor and the return
sensor on the boiler return.
▶ Do not spray leak detector onto cable entries, plugs or
electrical connecting leads. Do not let it drip onto
them either.
▶ To avoid corrosion, carefully wipe off the leak
detector afterwards.
