FINE TUNING THE EMBER-FYRE™ BURNER
Each installation is affected by altitude, vent configuration, and fuel quality. Because of this, the
restrictor and air shutter may need to be fine tuned to each installation. Follow the hints below to fine-
tune the burner for optimum performance and aesthetics.
Restrictor Hints:
Set the restrictor to the position suggested in the vent configuration table (see page 17). Turn the heater
on and allow it to reach full temperature (15 min.). If the flames indicate there is excessive draft due to
altitude or climate, you may wish to adjust the restrictor to a more restrictive position (higher number).
Active, flickering short flames are an indication of excessive draft. If the flames lift off of the burner
holes, this indicates not enough draft (restrictor is set too open). After adjustments are made the unit
must be cooled down to room temperature and restarted to make sure that the restriction is not so severe
that the pilot will drop out when it is restarted. If the pilot does drop out reduce the restriction until it will
operate continuously.
Air Shutter Hints:
•
For more glow, open the air shutter, however, this will make the flames more blue.
•
For yellow flames, close the air shutter, however, this may create less glow.
Correct Flames
The flames should burn right
off the top of the burner ports
(if they are too blue, adjust
the air control).
Warning: If the vent configuration is installed incorrectly the vent may cause the flames inside the heater to
lift or "ghost" – a dangerous situation. Inspect the flames after installation to insure proper
performance. If the vent configuration is correct, yet the flames are lifting or ghosting, shut off gas
to the heater and contact the dealer for information on remedying the problem.
