Basic Operation
Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the electrical
supply to the pump. Instead, shut off the gas supply at a location external to the appliance.
En cas de surchauffe ou si I'admission de gaz ne peut étre coupée, ne pas couper ni débrancher
l'alimentation électrique de la pompe. Fermer plutôt le robinet d'admission de gaz à l'extérieur de
I'appareil.
Do not use this boiler if any part has been under water. Immediately call a qualied service technician
to inspect the boiler and to replace any part of the control system and any gas control which has been
under water.
A. General This boiler is equipped with controls for
proper operation. All controls must be in proper
working order. Contact a qualied service agency
to provide annual maintenance as specied in the
Installation, Operating and Service Instructions.
Service on this boiler should be undertaken only
by trained and skilled personnel from a qualied
service agency.
1. Limit See Figure 1. A device which automatically
interrupts boiler operation when the water
temperature exceeds the set point. Maximum
allowable boiler water temperature is 250°F. Switch
differential is 30°F.
2. Blocked Vent Switch See Figure 1. A device
which automatically interrupts boiler operation
when excessive vent system blockage occurs. If the
control was activated to interrupt boiler operation,
do not attempt to place boiler in operation. Contact
a qualied service agency.
Do not reset Block Vent Switch unless a qualied
service agency has determined and corrected
the cause of any blockage in the vent system or
chimney.
3. Flame Rollout Switch See Figure 1. A device
which automatically interrupts boiler operation
when ames or excessive heat are present in the
vestibule. The control is a single use device. If the
control was activated to interrupt boiler operation,
do not attempt to place boiler in operation. Contact
a qualied service agency.
4. 24-Volt Continuous Ignition System (Standing
Pilot). See Figure 1. The Continuous Ignition
System consists of:
a. a combination gas valve to regulate gas ow to
burners.
b. a constant burning pilot burner to provide the
ignition source for main burners.
c. a thermocouple to sense pilot burner ame and
cause gas control valve to turn off main burner
and pilot burner gas ow should pilot burner
ame extinguish.
5. 24-Volt Intermittent Ignition System (EI). See
Figure 1. The Electronic Ignition System consists of:
a. an ignition module to initiate, monitor and stop
burner operation.
b. a combination gas valve to regulate gas ow to
burners.
c. a pilot burner to provide the ignition source for
main burners.
6. 120-Volt Intermittent Ignition (EP). See Figure 2.
The Intermittent Ignition System consists of:
a. an automatic main gas valve to regulate gas ow
to burners.
b. an automatic pilot gas valve to regulate gas ow
to the pilot burner.
c. a pilot burner to provide the ignition source for
main burners.
d. an ignition transformer to provide the ignition
source for the pilot burner.
e. a ame sensor to electronically monitor pilot
ame and cause gas control valve to turn off
main burner and pilot burner gas ow should
pilot burner ame extinguish.
B. Instructions to place boiler in operation and to turn
off boiler are shown on the Lighting or Operating
Instruction label posted on the inside of the front
removable door. See Figure 3 for front door removal
instructions. Lighting and Operating Instructions are
also shown in Figures 4 thru 6. Lighting and Operating
Instructions vary with the type of control system
furnished. Refer to Table 1 for the appropriate Figure.
