WARNING
Do not check for gas leaks with an open
flame -- use the bubble test. Failure to
use the bubble test or check for gas leaks
can cause severe personal injury, death, or
substantial property damage.
14. Turn on the gas supply at the manual gas valve.
15. Turn the power switch to the “ON” position.
16. Adjust the temperature set point on the control panel of
the SMART TOUCH control module to the desired
water temperature so the appliance will call for heat.
17. Check burner performance by cycling the system while
you observe burner response. The burner should ignite
promptly. Flame pattern should be stable. Turn system
off and allow burner to cool, then cycle burner again to
ensure proper ignition and flame characteristics.
Gas Pressure
The gas pressure must remain between 4 inches w.c.
(.99 kPa) minimum ( 5 inches w.c. for 1.0 models) and
14 inches w.c. (3.5 kPa) maximum for Natural gas and
between 8 inches w.c. (1.9 kPa) minimum and 14 inches
w.c. (3.5 kPa) maximum for LP gas during standby
(static) mode and while in operating (dynamic) mode.
If an in-line regulator is used, it must be a minimum of
10 feet (3 m) from the Armor X2 water heater. It is very
important that the gas line is properly purged by the gas
supplier or utility company. Failure to properly purge
the lines or improper line sizing, will result in ignition
failure.
The problem is especially noticeable in NEW LP
installations and also in empty tank situations. This can
also occur when a utility company shuts off service to an
area to provide maintenance to their lines.
Gas valve replacement
The gas valve MUST NOT be replaced with a
conventional gas valve under any circumstances. As
an additional safety feature, this gas valve has a flanged
connection to the venturi and blower.
Figure 7-3 Inlet Gas Supply Check
DO NOT adjust gas valve outlet
pressure. Attempting to alter the gas
valve outlet pressure could result in
damage to the valve, causing potential
severe personal injury, death, or
substantial property damage.
Failure to follow all precautions
could result in fire, explosion, or
death!
