MonIToRInG THe Gas flaMe
Periodically, the flames of the Clarity B-Vent Gas Heater
should be checked while it is operation. The flames should
be relatively well-defined and stable. They should be bright
yellow.with.a.blue.base.where.attached.to.the.burner.ports..
The flames should not look orange or sooty. Portions of the
logs will glow red when the flames are properly adjusted.
If you find the flames to be other than that described here,
do not operate the heater. Consult a qualified service person
or.your.Harman.dealer.for.advice...

The final step of the installation is to check the flame
pattern,.which.should.resemble.the.pattern.illustrated.in.the.
right column: The flames should be relatively well-defined
and.stable..They.should.be.bright.yellow.with.a.blue.base.
where.attached.to.the.burner.ports,.and.should.not.look.
orange.or.sooty...
Start.the.heater.according.to.the.directions.on.page.11.and.
allow.the.heater.to.burn.for.approximately.15.minutes..The.
flames will increase in length and become more yellow in
color.as.the.Clarity.heats.up.
If the flames do not resemble the description above and
the illustration in the right column, the air shutters may be
adjusted.
Three.separate.screws—one.for.each.burner—are.used.to.
adjust the flames for a particular installation. Two of them
are.accessible.through.the.side.access.port.on.the.right.side.
of.the.stove..The.third.is.accessible.from.the.front.when.the.
control.door.is.open..The.screws.may.become.hot.to.the.
touch.after.prolonged.operation..Use.a.3/16".Allen.wrench.
to avoid contact if hot. For best results when fine-tuning the
flame picture, initially leave the middle screw unchanged
from.its.factory.setting..Turn.the.other.two.screws.as.needed.
to increase or decrease the brightness and length of the flame:
turning counterclockwise will increase the flame; turning
clockwise will decrease the flame.
