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 qualified 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 qualified service agency 
to provide annual maintenance as specified in the 
Installation, Operating and Service Instructions.
Service on this boiler should be undertaken only 
by trained and skilled personnel from a qualified 
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 qualified service agency.
Do not reset Block Vent Switch unless a qualified 
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 flames 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 qualified 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 flow to 
burners.
b.  a constant burning pilot burner to provide the 
ignition source for main burners.
c.  a thermocouple to sense pilot burner flame and 
cause gas control valve to turn off main burner 
and pilot burner gas flow should pilot burner 
flame 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 flow 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 flow 
to burners.
b.  an automatic pilot gas valve to regulate gas flow 
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 flame sensor to electronically monitor pilot 
flame and cause gas control valve to turn off 
main burner and pilot burner gas flow should 
pilot burner flame 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.
