Step 9. Checking Unit Operation - Superior SSBV-3530CNM Installation Instructions Manual

Step 9. CHECKING APPLIANCE
OPERATION
With the gas line installed, run initial system
checkout before closing up the front of the
appliance. Follow the pilot lighting instructions
provided in the Homeowner's Care and Opera-
tion Instructions. For piezo igniter location see
Figure 22 (millivolt appliances only).
Note: The (pull-out) Lighting instructions label
can be found in the control compartment
(see Figure 20).
When fi rst lighting the appliance, it will take
a few minutes for the line to purge itself of
air. Once purging is complete, the pilot and
burner will light and operate as indicated in
the instruction manual. Subsequent lightings
of the appliance will not require such purging.
Inspect the pilot fl ame.

The pilot fl ame should be steady, not lifting
or fl oating. Flame should be blue in color with
traces of orange at the outer edge.
The top 3/8" (10 mm) at the pilot generator
(thermopile) and the top 1/8" min (tip) of the
quick drop out thermocouple should be engulfed
in the pilot fl ame. The fl ame should project 1" (25
mm) beyond the hood at all three ports (Figure
23 - SIT, Figure 24 - Honeywell )
To light the burner; rotate the gas valve control
knob counterclockwise to the "ON" position
then turn "ON" the optional control switch,
if applicable (see Installation Accessories on
Page 19).
Observe the individual tongues of fl ame on
the burner. Make sure all ports are open and
producing fl ame evenly across the burner. If
any ports are blocked, or partially blocked,
clean out the ports.
