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.	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.
