SERIES TWO HEATER
All NECO heaters are constructed of durable weather-
resistant materials, so a minimum amount of service
should be required; however before the unit is started
for the first time each season there are a few items
that need to be checked out. All damaged parts should
be repaired or replaced.
1. Disconnect and lock out power to fan and heater.
Open control box lid and inspect all components for
moisture, vibration or rodent damage. Inspect and
tighten all loose terminal connections. Replace any
damaged wiring.
3. Inspect burner for wear or foreign material in any of
the ports. Clean or replace parts if necessary.
4. Inspect the spark plug and flame probe for corrosion
and damage. Clean or replace if necessary.
