4.2 Operation
4.2.1 Gas burner operation
• Starting (& flame out) – Cool flame sensor is closed, which
bypasses secondary coil & turns on igniter & holding/booster
coils (to open dual valve). Secondary coil is off (so no gas
flows to burner). Igniter current is ~ 4 A.
• Running – Igniter heats up & opens flame sensor, which turns
off igniter & turns on secondary coil (so gas flows to burner).
Hot igniter ignites gas – flames keep flame sensor open.
Booster coil turns off since current flows thru secondary coil &
igniter (~ .1 A) – holding coil stays energized to keep gas
flowing.
4.2.2 AQUASTOP
®
(aqua secure) hose operation
The AQUASTOP
®
hose consists of a sealed inner and outer hose and
a leak detection / shut-off assembly. A spring holds a plunger open
allowing the inner hose to carry water. If an inner hose ever should
leak, water fills the outer hose where a sponge in the hose end
(connected to the water line) absorbs water, pulling a plunger down to
stop water flow and show red in the indicator window. The outer hose
is sealed and won’t leak.
Any remaining water pressure won’t re-open the hose, but will help
keep the hose closed.
The hose has a one-time failure duty. If an inner hose should ever
leak where the indicator shows red, the hose must be replaced.
AQUASTOP
®
hoses stop hose leaks, whether appliances are on or
not. They’re superior to braided hoses, whether nylon or ss, and can
be used with any washer (or misting dryer) with standard US threads
(3/4” NH, 11.5 threads/inch).
