CS8800 Water Heater
Pilot Burner Assembly
The CS8800 Pilot Burner Assemblies provides standing
pilot ignition of the main burner and power for the
WT8800 control module and VT8800 valve. The CS8800
is a primary aerated pilot burner.
On some models a temperature cut out switch (TCO) is
provided to sense a clogged flame arrestor or a
flammable vapor incident. When the TCO opens, the
power to the control is interrupted and pilot goes out.
There are separate LP and natural gas models.
The CS8800 Pilot Burner was designed for gas fired hot
water tank heating applications.
