DANGER
FLAMMABLE VAPOUR
Vapours from flammable liquids can
explode and cause fire resulting in
death or severe burns.
Do not use or store flammable
products such as gasoline, solvents,
or adhesives in the same room or
area near the boiler.

Store flammable products far away
from the boiler in approved
containers, with the lid tightly
closed, and out of the reach of
children.

The boiler’s main burner ignites
automatically at various intervals
and may ignite flammable vapours.

Flammable vapour is invisible, is
heavier than air, and can travel
long distances at floor level.
Dangerous concentrations of
flammable vapour can be moved
by air flow from other rooms
towards the main burner flame.
