CFM UVHK29MN Manual De Usuario

A periodic visual check of the flames should be made.  The pilot 
flame should always be present when the appliance is in opera-
tion.  (Fig. 10)
In normal operation (at full rate for approximately 15 minutes) 
the following flame appearance should be observed:

When installed in a  wood burning fireplace, the heat output 
from the appliance can be controlled by the position of the flue 
damper if it is installed in a wood-burning fireplace.
The damper setting should be fully closed for maximum heat 
output, partially closed for less heat output and fully open for 
minimum heat output.
The appliance may be used in a working solid fuel burning fire-
place with the flue damper closed only if unvented appliances 
are permitted by local state and city codes.  It may also be 

operated as a decorative appliance whose prime function lies in 
the aesthetic effect of the flames when installed in a solid fuel 
burning fireplace with the flue damper open.  If unvented heat-
ers are not permitted, the fireplace vent damper must be locked 
at a minimum vent area of 15 sq. ins.
Whenever the appliance is operated with the fireplace’s flue 
damper closed, glass doors - if present - must be open and 
the outside air damper and the ash dump (if the fireplace is 
equipped with either one) must be closed.

Main BurnerFlame: The flame should be yellow in color and 
should extend about 6 inches above the large front log.
Typical flame shape as seen in Figure 11.
NOTE: For your safety, the appliance is equipped with an 
oxygen depletion system. The system senses the oxygen in the 
atmosphere and switches off the gas supply in case the level of 
oxygen falls below a safe level. It must not be altered in any 
way.

CAUTION:  Before cleaning or moving logs or other parts of the 
unit, be sure to read the section on important safeguards.
Cleaning should be done before the logs are used each year 
and after long periods of non-use.
All cleaning should be carried out when the appliance is cold.
Only limited cleaning will be required under normal use.  Dust-
ing the front grate or the control knob panel may be required 
occasionally.  Do not use any cleaning fluids to clean the logs or 
any other part of the appliance.
If the flames show any unusual shapes or behavior, or if the 
burners fail to ignite properly, then the burner holes may require 
cleaning.  If this occurs contact your nearest dealer to get the 
appliance serviced.

Alternatively, the appliance can be cleaned by removing the top, 
front and rear logs.  Handle the logs gently so as not to damage 
them.  Always lift each log by holding it carefully at each end. 
After the logs are removed allowing access to the burner area,  
use a vacuum cleaner to carefully remove dust, spider webs 
and loose particles from the base, logs and from around the 
burner.  Gloves are recommended to prevent the ceramic fibers 
that compose the logs from pricking your skin.  If the skin is 
pricked, wash gently with soap and water.  Use extreme cau-
tion in clearing around the pilot (ODS).  The pilot should not be 
moved or altered from the original factory setting (Pilot to burner 
preset location).  The burner should not be removed or taken 
out of it’s locked and secure position (proper location of burners 
are critical).
