Installation Instructions

HIGH ALTITUDE INSTALLATIONS

Set dip switches 2 and 3 to the values shown in the table below for your altitude. The default setting for the appliance is 0-2000 ft (0-610 m) with switches No. 2 and No. 3 in the OFF position.

WARNING: Do not adjust the other dip switches unless specifically instructed to do so.

If unsure of the altitude in your location, call 1.888.HOTWTER (888.467.9837).

CASCADING MULTIPLE WATER HEATERS

The Dual Connect Cable Kit (AGTDC1) is an optional accessory that connects 2 water heaters and allows them to function as one hot water source.

The Multi Connect Kit (AGTCK1) and the Multi Connect Cable Kit (AGTMC1) are optional accessories that connect 3 to 5 water heaters and allow them to function as one hot water source.

Refer to the instructions that come with the accessory for complete installation information.

GUIDELINES

Do not install the Dual Connect Cable Kit (AGTDC1) with the Multi Connect Kit (AGTCK1) and the Multi Connect Cable Kit (AGTMC1) because they are not designed to operate together.

Water heaters should be installed less than

18 inches apart so that the cables will reach between units and to prevent temperature fluctuations (cold water sandwich effect) when the water is shut off and turned back on.

Temperature settings can only be changed on the controller for the primary unit.
