OPERATION
4) When the pilot is lit keep knob pressed for up to 20
seconds to heat the thermocouple flame sensor, then
release it (first ignition generally takes more time,
because the gas circuit is full of air).
5) If the pilot does not stay lit, repeat steps 3 and 4.
6) Turn knob to "LOW " position.
7) Adjust the heat input by turning the knob from the "LOW"
position, to the "HIGH" position, as required.
8) After lighting, turn knob from "LOW " to "HIGH", position
and back, to check flame stability.
9) In case of accidental break down of the flame (due to
wind or other reasons), a Flame Safely Device (FSD) will
automatically shut-off gas supply within 90 seconds.
If you experience any ignition problem consult the following
"Troubleshooting".
These lighting instructions must be followed. An unsafe
condition can occur if they are not followed correctl
