The following terms are used throughout this manual to bring attention to the presence of hazards of various risk levels.

Basic Operation

A.

  General.

 This water boiler utilizes fan-assisted 

combustion and 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 Installation, Operating and 

Service Instructions.

1.  Limit.

 See Figure 1. A device which automatically 

interrupts boiler operation when the water 
temperature exceeds the set point. Maximum 
allowable temperature is 240°F.

  Original equipment with this boiler is a Honeywell 

L4080D1036. Boiler operation is interrupted when 

system temperature reaches cut-out temperature. 

Boiler operation resumes automatically when system 
temperature falls 30°F to cut-out temperature.

2.  Flame Rollout Switch.

 See Figure 1. A device 

which automatically interrupts boiler operation 

when flames or excessive heat are present in the 
combustion area enclosure. The control is a single 
use device.  The control is located in the combustion 

area enclosure.   If the control was activated to 

interrupt boiler operation, do not attempt to place 

boiler in operation. Contact a qualified service 

agency.

WARNING

Service on this boiler should be undertaken only 

by trained and skilled personnel from a qualified 

service agency.

3.   Pressure Switch.

 See Figure 1. A device which 

automatically prevents or interrupts boiler 
operation when the induced draft blower fails to 

move sufficient combustion air for proper burner 

operation. Boiler operation resumes automatically 

when sufficient combustion air flow is reestablished.

4.  Electronic Ignition System.

 The Electronic Ignition 

(EI) System consists of:

a.  a solid state ignition control module to initiate, 

monitor and stop burner operation. See Figure 1.

b.  a combination gas valve to regulate gas flow to 

the burners. See Figure 1.

c.  a pilot burner to provide the ignition source for 

the main burners.  See Figure 4.

CAUTION

Indicates a potentially hazardous situation which, 

if  not  avoided,  may  result  in  moderate  or  minor 
injury or property damage.

WARNING

Indicates a potentially hazardous situation which, 

if not avoided, could result in death, serious injury 

or substantial property damage.

CAUTION

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.
