3.1 SMOKE SAFETY DEVICE
(fig. 6)
The smoke stat provides a protection
against the discharge of flue gas into
the atmophere (5).
This control device stops the gas valve

boiler room is continuous way and in
such quantities as to become dange-
rous.
To start the boiler again, switch off the
power, then remove the smoke stat
cover and reset the button below.
If the thermostat continues to trip off,
it will be necessary to check the flue
thoroughly, making all the necessary
changes to ensure it works properly.

ghtdiverter support bracket and fixed

nut already mounted on the capillary
