Remove the front cover panel on the water heater.
Find DIP Switch 2 located in the top-right portion of
the control board. The switch labeled “DIP 2” is the
bottom switch.
The factory settings for this switch should all be in
the OFF position (DOWN).
If altitude is above 2000 ft. (610 m) and below
5,400 ft. (1650 m), change the third switch on “DIP
2” to the ON position (UP).
If altitude is above 5,400 ft. (1650 m) and below
8,500 ft. (2590 m), change the fourth switch to the
ON position (UP).
NOTICE:
DO NOT alter any other DIP switch settings. The
manifold pressure will be reduced accordingly.
Some models are not available at higher than
5400 ft (1650m). Please contact technical service
listed on page 26 of this use and care manual if
you have any questions of high altitude DIP switch
adjustments.
Replace the front cover panel.
Turn on the gas and water to the water heater by
opening the shut-off valves.
