Suburban DYNALINE DL3-0912 User Manual

Suburban DynaLine Owner's Manual 10/2017 Rev.1 6
You as the owner/user should inspect the unit periodically during the
heating season. Particular attention should be given to the following:
A. Periodically observe the main burner ame to assure it is burning with a hard
blue ame with well-dened burner ports. (See Figure 16.) If ame appears
yellow or burner has a lazy ame, shut furnace down and contact a qualied
service person.
B. Periodically inspect the vent for obstructions or presence of soot. Soot is
formed whenever combustion is incomplete. This is your visual warning that
the furnace is operating in an unsafe manner. If soot is present, immediately
shut furnace down and contact your dealer or a qualied service person.
C. Circulating air through the front grille must not be blocked. Keep lter clean to
assure adequate air ow.
The removable, washable type lter should be cleaned or replaced several
times during the year. This will depend upon the usage and location of the unit.
Dirty lters restrict air ow across the heat exchanger and coils. This results
in inadequate cooling and shortens the life expectancy of the heat exchanger,
motors and compressor.
FILTER REMOVAL
1. The lter is located behind the cabinet front. Remove cabinet front by lifting
up. Slide lter up until free of left tab.
2. Filter may be washed in a soapy solution and rinsed in clear water. Let lter
dry before reinstalling it on the unit.
3. Reinstall lter.
