WATER HEATER CONTROL

TROUBLE SHOOTING

Please check guidelines below. For your safety, water heater service should be performed only by a qualified service technician.

Read the GENERAL SAFETY INFORMATION section first.

				3 & 4 with an ohm meter. 2.1 If the reading taken is more
				than 100,000 (50,000 for data code before 0616; 70,000
				for data code 0617 through 0709) ohms replace the ignitor
				assembly. 2.2 If the reading taken is less than 100,000
				(50,000 for data code before 0616; 70,000 for data code
				0617 through 0709) ohms replace Intelli-Vent™ control.

				contacts at normal operating temperatures during heating
				cycle - replace the vent temperature limit switch.
			3.	Ensure water heater is not over-firing. 3.1 Check burner
				orifice size and ensure the correct orifice is installed;
				replace as necessary. 3.2 Check manifold gas pressure
				and ensure it is within 0.3” W.C. (75 Pa) of listed rating on
				Intelli-Vent™ control valve. Manifold gas pressure is
				non-adjustable, if manifold gas pressure is off by more
				than 0.3” W.C. (75 Pa), replace the Intelli-Vent™ control.
			4.	Ensure condensate lines are not obstructed. Check and
				clear all condensate lines including the floor condensate
				drain line.
