PA1628 H3-41, H3-45 Operator’s Manual 

 

WARNING

 

The coolant heating system uses the same 
fuel as the engine.  Do not operate in a 
closed building or while refueling.  Operate 
only in a well-ventilated area. 

The coolant heater is located in a compartment 
in the lower part of the rear electrical 
compartment.  To access the coolant heater, 
remove the panel in the rear electrical 
compartment. 

 

COOLANT HEATER (104,000 BTU) 

22224 

SWITCHING THE HEATER ON 

The timer light illuminates when the heater is 
switched on.  Air is forced in to flush out the 
combustion chamber of residual gases and the 
water circulation pump begins operating.  The 
fuel metering pump delivers fuel in precise 
amounts to the combustion chamber, where 
fuel and combustion air form a combustible 
mixture which is ignited by the ignition unit. 

Once the flame sensor has signaled to the 
control unit that combustion has taken place, 
the ignition unit is switched off. 

Hot combustion gases are diverted at the end of 
the flame pipe and are then forced through the 
indirect heating surfaces of the heat exchanger.  
The heat exchanger transfers the heat to the 
coolant water passing through the heat 
exchanger. 

The heater is thermostatically controlled and 
operates intermittently (i.e., the switched-on 
time of the burner varies depending on the heat 

requirement).  The water temperature is 
controlled by the built-in water thermostat. 

The water circulation pump remains in operation 
as long as the heater is operating, even during 
the regulated intervals and during the delayed 
cut-out of the heater. The pump can also be 
operated independently of the heater by means 
of an appropriate circuit. The heater can be 
switched 

ON

 at any time (i.e., during the delayed 

cut-out period).  Ignition takes place after the 
delayed cut-out time expires. 

SWITCHING THE HEATER OFF 

The fuel supply is interrupted when the heater is 
switched 

OFF

.  This causes the flame to go out 

and a delayed cut-out of 2.5 minutes begins.  
The circulating combustion air flushes the 
remaining combustion gases out of the chamber 
and cools off the heated parts on the exhaust 
side of the heat exchanger.  The water 
circulation pump continues to transfer the 
latent heat present in the heat exchanger, thus 
preventing hot spots.  Once the delayed cut-out 
time expires, both the combustion air blower 
and the water circulation pump switch 

OFF

 

automatically.  A cut-out will automatically take 
place in case of heater failure. Refer to Section 9 

Technical information

 for additional information. 

COOLANT HEATER TIMER 

The timer, located on L.H. lateral console is used 
to program the starting and stopping time of 
the preheating system and to give Fault Codes. 
The system indicator light, located on the timer, 
illuminates when the system is functional.
