DO NOT PLACE PROPANE
SENSOR HIGH UP ON CEILING IT WILL TELL YOU NOTHING! A VERY DANGEROUS THING TO DO!!!!
Propane /Lpg is heavier than air so will sink into the
bilge follow this
advice as:
The fume detector - The panel should also be fitted with a fume detector test switch and
alarm. The
sensor (s) themselves should be
mounted directly under the appliance. Many install the sensor in the
bilge. If the fumes reach the bilge .... it's too late.
