Fulton Pulse DWH (PDWH) Domestic Water Heater - Manual (Page 30)

Post these instructions in an
appropriate place near the
water heater and maintain in
good legible condition.
WARNING
If you do not follow these instruc-
tions exactly, a fire or explosion
may result causing property dam-
age, personal injury, or loss of life.
Fulton Pulse water heaters
do not have a pilot. They are equipped
with an ignition device which automati-
cally lights the water heater. Do not try
to light the water heater by hand.
BEFORE OPERATING:
Smell all around the water heater area
for gas. Be sure to smell next to the floor
as some gas is heavier than air and will
settle.
IF YOU SMELL GAS:
Do not light any appliance.
Do not touch any electric switch.
Do not use any phone in your building.
Immediately call your gas supplier from
a neighbor’s phone, and then follow
your gas supplier’s instructions. If you
cannot reach your gas supplier, call the
fire department.
Use only your hand to turn the gas cock
knob. Never use tools. If the knob will
not turn by hand, don’t try to repair it.
Call a qualified service technician.
FORCE OR ATTEMPTED REPAIR MAY
RESULT IN A FIRE OR EXPLOSION.
NOTE
DO NOT use this water heater if any part
has been under water. Immediately call a
qualified service technician to inspect the
water heater and to replace any part of
the control system and/or gas control(s)
which has been under water.

turn to “ON”.
Turn on all electric power to the water
heater. Turn operating switch on water
heater to “ON” position. The water
heater is energized and the 35 second
prepurge begins. After 35 seconds the
spark ignitor and gas valves (2 seconds
later) are energized. If combustion is not
sensed within 4 seconds, gas and spark
are de-energized. The control will
recycle to prepurge, only if the selected
number of retry attempts is not
exceeded.
If after 37 seconds the gas valve
opens but the water heater does not
start, check the spark plug to be sure it
is working properly.
The plug may be bad or the plug wire
may be loose. Check gap of plug It
should be .050" to .060". When
replacing plug be sure to use Never
Seize on threads of plug.
When the unit fires and pressure is
sensed in air valve housing, the unit will
continue to operate until main power is
shut off to the controller either through the
temperature switch or main power switch.
Once the pressure is sensed in the air
valve housing (proof of flame), the
blower and spark will turn off.
