Air Shutter Adjustment; Monitoring The Gas Flame - Harman Stove Company Clarity 929 DV Installation And Operating Manual

AIR SHUTTER ADJUSTMENT

The final step of the installation is to check the flame pat-
tern, 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 or-
ange or sooty.
Start the heater according to the directions on page 12
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; turn-
ing clockwise will decrease the flame.
1. To adjust the rear burner, open the right wing door,
reach through the side access port, and turn the rear screw
to adjust flame (see directions above).
2. To adjust the front burner, first open the control door,
then turn the front screw to adjust flame (see directions
above).
Repeat the procedure as needed until the desired flame
effect is achieved.

Monitoring the Gas Flame

Periodically, the flames of the Clarity Direct 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 ad-
justed.
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 Clarity flame pattern will resemble this when the unit is
burning properly.
The properly-burning pilot will
resemble the illustration to the
right.
