Vertical gas pipes must be equipped with a siphon and provided with a drain for the con-
densate that may form inside the pipe during cold periods. It may also be necessary to
insulate the gas pipe to prevent the formation of excessive condensate.
In any case, provide a cut-off valve (cock) on the gas supply line, to isolate the appliance
if required.
For data regarding hourly fuel consumption of the appliance, refer to Table 2.1 GAHP-A LT
technical data on page 12 or Table 2.2 GAHP-A HT technical data on page 13.

CONDENSATE DISCHARGE CONNECTION
The fumes condensate outlet is on the left of the unit.
The unit is supplied complete with a siphon to which a piece of pipe is attached. During
transport, the pipe is stored inside the unit’s left mounting bracket at the front of the
appliance.
To install/connect the pipe, proceed as follows:
1. Pass the pipe through the hole in the left mounting bracket (see Figure 4.3 Position
of condensate discharge and manual reset fumes thermostat on page 35).
2. Connect the tube to a plastic condensate discharge manifold of the correct
length.
3. The connection between the pipe and the condensate manifold must be in a visible
location.

The condensate discharge to the sewer must be:
• sized so as to discharge the maximum condensation fl ow (see Table 2.1 GAHP-A LT
technical data on page 12 or Table 2.2 GAHP-A HT technical data on page 13 under
the respective heading);
