				3.	If previous steps are correct and fault persists, replace the
				module
96	Outdoor		sensor	1.	Check wiring and correct any possible errors.		H
	fault			2.	Replace the outdoor sensor.
				3.	If previous steps are correct and fault persists, replace the
				module.
97	Internal Fault: A2D			Internal Fault.			L
	mismatch.			1.	Reset Module.
98	Internal		Fault:	2.	If fault repeats, replace module.		L
	Exceeded		VSNSR
	voltage tolerance
99	Internal		Fault:				L
	Exceeded		28V
	voltage tolerance
100	Pressure		Sensor	1.	Verify the Pressure Sensor is a 4-20ma source.		H
	Fault			2.	Check wiring and correct any possible errors.
				3.	Test Pressure Sensor for correct operation.
				4.	Replace the Pressure sensor.

105	Flame detected out			1.	Check that flame is not present in the combustion chamber.		H or L
	of sequence			Correct any errors.
				2.	Make sure that the flame detector is wired to the correct
				terminal.
				3.	Make sure the F & G wires are protected from stray noise
				pickup.
				4.	Reset and sequence the module, if code reappears, replace
				the flame detector.
				5.	Reset and sequence the module, if code reappears, replace
				the module.
106	Flame lost in MFEP			1. Check pilot valve (Main Valve for DSI) wiring and operation -			L
107	Flame	lost	early in	correct any errors.			L
	run			2.	Check the fuel supply.
108	Flame lost in run			3.	Check fuel pressure and repeat turndown tests.		L
109	Ignition failed			4.	Check ignition transformer electrode, flame detector, flame		L
				detector setting or flame rod position.
				5. If steps 1 through 4 are correct and the fault persists, replace
				the module.
110	Ignition		failure	Hold time of recycle and hold option. Will not be a lockout fault.			H
	occurred			Hold Only. Internal hardware test. Not a lockout.
111	Flame		current				H
	lower	than	WEAK
	threshold
112	Pilot	test	flame	Interrupted Pilot or DSI application and flame lost when system			L
	timeout			in “test” mode.
				1.	Reset the module to restart.
113	Flame		circuit	Flame sensed during Initiate or off cycle, hold 240 seconds, if			L
	timeout			present after 240 seconds, lockout.
