Suburban Water Heater Problem Lighting
Subarban water heater model SW12DEL sometimes lights at first try other times it tries to light 6 times. Someone told me it should try 3 times then lockout. Any idea whats going on?

Not all have 3 tries/lock out system.
Need to clean the gas orifice (remove it and clean with alcohol) clean out burner tube and check spark electrode position.
Spark electrode to ground rod gap 1/8" and positioned IN main flame.
The burner tube needs to be 'straight' (in direct alignment with gas valve so gas flows down the center of tube----adjust if needed by repositioning gas valve)
Open outside compartment and watch operation while somebody turns it ON
Is spark strong?
When main flame lights......is it strong blue flame?
Is spark electrode engulfed in main flame?
