32.5 Example gas ramp R 1 1/2" screwed
The gas ramp is generally mounted from the burner side: vertically down, to the right or left and backwards.
Gas ramp mounting can however be adapted to location-specific requirements.

Protection and test pressures
The components of this example gas ramp are designed for a max. protection pressure of 360mbar.
Compliance with this max. value must be ensured by way of relevant pressure control and safety de-
vices.
Test pressure up to and including the double gas valve = 1.5 x p
e
= max. 360mbar.
Test pressure downstream of double gas valve up to burner connection flange = operating pressure of
burner at max. load.
Conduct test with foaming agent or a gas detector device.
