2. Check all electrical connections for tightness and proper voltage. 3. Check water heater tank to make sure it is full of water. (Remove air through T&P valve). 4. Pull nozzle assembly from burner and check gap settings on electrodes (see I&M). 5. While nozzle is removed, look inside through burner for obstructions. 6. Check fan rotation and purge air from oil pump by bumping motor contactor. 7. Check air shutter setting (guideline on burner tag). 8. Drill hole in vent pipe 12” to 24” from hea
