U.
Water Boiler with Intermittent Ignition (EI) and
Tankless Heater. See Figure 48.
1. Normal Operation
a. Thermostat calls for heat or low limit senses
water temperature below set point.
b. Vent Damper (if used) opens as stated in Vent
Damper Sequence of Operation.
c
.
Ignition Module is energized. Pilot Valve opens
and Igniter is energized to ignite Pilot Burner.
d. Sensor proves presence of pilot flame. Main
Valve(s) opens and ignites Main Burners.
e
.
After Thermostat or low limit is satisfied Ignition
Module is de-energized, extinguishing pilot and
main flame. Vent Damper (if used) closes.
2. Safety Shutdown
a
.
Limit: Automatically interrupts main burner
operation when water temperature exceeds set
point. Maximum allowable temperature is 250°F.
Normal operation resumes when water
temperature falls below set point.
b
.
Blocked Vent Switch. Automatically interrupts
main burner operation when excessive vent
system blockage occurs. Control is a multiple
use device. If blocked vent switch is activated do
not attempt to place boiler in operation. Correct
source of blockage and reset blocked vent
switch.
c
.
Flame Roll-out Switch. Automatically interrupts
boiler operation when flames or excessive heat
are present in vestibule. Control is single use
device. If flame roll-out switch is activated do
not attempt to place boiler in operation. Correct
source of blockage and replace flame roll-out
switch.
d
.
Igniter/Sensor: senses pilot flame and causes
ignition module to turn off main burner and pilot
burner gas flow should pilot burner flame
extinguish. Five to six minutes after shutdown,
Ignition Module restarts ignition sequence.
