FLUE GAS PROTECTOR
OPERATION AND CONNECTION
Water heaters are equipped with a de-
vice which shuts of gas to the burner and
hence stops the unit working when the
fl ue is partly or completely obstructed.
This device is composed of a thermostat
(A) set to 87±3°C mounted to the edge of
the hood (B) and connected to the fi tting
interrupted by the gas valve.
This is part of the hood kit provided with
the appliance, and must be installed as
described below.
Install the fl ue gas hood "A" turning it
•
to the best position with reference to
the sensor "B" and the cable exit from
the water heater.
• Connect the cable terminals "C" to
the contacts of the fl ue gas protector
(Fig.2).
• Proceed with normal water heater
start-up.
Should the appliance block, it must be
re-started as follows:
• as followswait 10 minutes after the
block occurs;
• ully press the re-arm button "D" on the
thermostat (Fig.3);
• re-start the water heater by following
the instructions for the normal ignition.
Should the defect repeat, do not repeat
appliance ignition but request the inter-
vention of a qualifi ed technician to re-
move the cause of the problem.
Make sure that the combustion products
are properly expelled by measuring the
CO
content at the nominal heat output.
