5.0 Start-Up & Adjustment
(continued)
Check For Smoke
If smoke is present in the exhaust, gradually close the gas butterfly valve until the
smoke disappears.
Adjust Low Fire
Drive the burner to low fire. Check the tube outlet for smoke. If smoke is present,
adjust the adjustable bias proportionator as detailed in Figure 8. If smoke is still
present, then the air butterfly valve may need to be opened more. Readjust the
valve linkage to provide more air at low fire.
Recycle to Verify Firing Rates
Cycle the burner several times to verify that the system is properly adjusted at all
firing rates.
Burner Shutdown
Turn the main and pilot gas valves off.
Turn the burner on/off switch to “off.”
