wire #14 to neutral. If no voltage is present at wire

#14, and motor is running, replace burner blower

“24V”, if no voltage is present, trace wiring back to

centrifugal switch. Check for 120VAC to ignition

control at terminal “L1” to neutral. If no voltage is

present, trace wiring back to main power switch.

When 24VAC is supplied to the ignition control, the

ignition control switches 120VAC to the hot surface

igniter If 24VAC and 120VAC are supplied to ignition

control, but there is no voltage at the hot surface

igniter, replace the ignition control. Hot surface igniter If 120VAC is present at hot surface igniter terminals,

visually check to see that the igniter is heating

(igniter may be viewed through the port in the end of

burner tube). The igniter should glow bright red. If the

igniter does not heat, replace the hot surface igniter. Ignition control After 45 seconds of hot surface igniter pre-heat, the

ignition control will switch 24VAC to the gas control

valves. Check for 24VAC output from ignition control

across terminals marked “valve” and “valve gnd”. If

no voltage is present, replace ignition control. Gas control valves When 24VAC is supplied to the gas control valves,

the valve should open. Check for gas pressure at the

manifold tap located just before the burner. If there is

no pressure, check the incoming gas supply to be

sure all manual valves are open and flexible gas

hose is properly connected. If gas is present, and the

gas control valve is energized, but there is no gas

pressure at the burner manifold, replace the gas

control valves. Flame will not stay lit Hot surface igniter Six seconds after the gas valve opens, ignition must
