serves.a.separate.solid-fuel.burning.appliance.
The.venting.manufacturer's.installation.instructions.must.
be.followed.exactly.
IMPORTANT: Because of the high efficiency and low
flue gas temperatures of this appliance, it is important that
it be connected to a well-sealed and efficient venting system
which.is.capable.of.registering.a.negative.pressure.while.
the.stove.is.in.operation.
The most efficient venting systems are those that have a
minimum.number.of.bends.and.minimal.horizontal.runs.
The.Clarity.gas.heater.is.equipped.with.a.thermally.acti-
vated.vent.safety.switch.that.will.shut.down.the.main.burner.
if.the.heater.is.not.properly.venting..The.safety.switch.will.
automatically.reset.after.the.heater.has.cooled.down.
