* For BTU/hr Natural gas multiply by 1000 BTU/hr;
for Propane multiply by 2500
____ 5. If the firing manifold has been readjusted,
redo steps 2 and 4
____ 6.Check that the draft over-fire is positive
BURNER OPERATION: Record the Readings at Steady State
Draft over fire at steady state (should be –0.02 “W.C. to +0.50 “W.C.)
Draft in the Breech at steady state (refer to heat exchanger manual for details)
