washer installed.
2. Confirm the wiring harness and connections for 120VAC power and
between the blower and SOLA base.
Controller / Settings Increase light off RPM rate (Configure Menu >> Burner Control Timings and
Rates) without exceeding approved ranges.
Boiler / Maintenance Items 1. Verify that the Dungs gas filter is clean (blue). See page 4-4 in the Manual

pipe when the unit is off, and adjusts to the appropriate 25-30 degree range
during light off.
3. Confirm that the correct ignitor for the burner is installed with the bridge,
proper offset, and proper gaping. See page 4-5 in the Manual.
4. Verify that the ignition transformer has power and the Ignitor is sparking.
5. Verify Gas pressure (Incoming to the Dungs lockup regulator >4"WC at high
fire, Incoming to Dungs MBC gas valve >3"WC at high fire)
6. Verify that solenoid on the enrichment gas train is actuated during light off
and an appropriate amount of gas pressure is seen (1.0 to 3.5"WC)
7. Verify Venting Pressures and Configurations. See page 2-21 in the manual
for acceptable ranges and installation.
8. Increase the MBC Dungs Valve Offset up to 1 full turn positive.
