Section 8, Operating the WaterHeater 

8.2  Turning the Power to The 

WaterHeater™ by ITR “ON” 

 

The WaterHeater™ by ITR’s Control Panel located on the 
WaterHeater™ itself contains three push buttons: ON/OFF 
power, Bypass and Reset.  The power switch must be pushed 
ON (power LED will turn ON) to turn the DC electrical power 

to the main Control Board and WaterHeater™ ON and is 
required to be left ON during any period where heat is 
requested.  When The WaterHeater™ by ITR is shut down for 
any extended period or the season it is recommended that 
the power switch be turned OFF.

  

8.3  Activating the Burner (Primary)  

Activating the Burner (Primary Heat Source)  

  NOTICE 

     Do not operate 

the 
WaterHeater™ 

until it is filled 
with water and 
all trapped air 

has been bled. 

 

     Use only a non 

toxic propylene 

glycol based 
coolant with 

additives 
generally 
recognized as 

safe ”GRAS” by 
the FDA in the 

coolant side of 
the Space 

Heating Module 

 

The burner switch on the Remote Operating Panel controls 
the ON/OFF of the diesel burner (primary heat source).  
When the burner switch is turned ON, the diesel portion of 
The WaterHeater™ by ITR will turn on after ten seconds.  The 

Burner LED on the Remote Operating Panel will turn ON when 
the diesel burner has been activated.  The burner will 
continue to operate until the water in The WaterHeater™ by 
ITR reaches the set operating temperature range.  At this 
point, the diesel burner will turn OFF.  If The WaterHeater™ 
by ITR water should cool to outside of this temperature 

range, the burner will again come on and will continue until 
either the burner switch on the Remote Operating Panel is 
turned OFF or the temperature range is again achieved.  If 
the burner switch on the Remote Operating Panel is turned 
OFF, the burner stops and The WaterHeater™ by ITR enters a 

two minute cool down stage prior to completely shutting 
down. 

Activating the AC immersion element (Secondary Heat 
Source)  

 

Turn the AC breaker panel circuit breaker to the AC element 

ON. The AC Heat (green) LED on the remote operating panel 
will turn ON indicating the AC element is energized and the 
water is being electrically heated. It will continue to operate 
until the water in the WaterHeater reaches the set operating 
temperature range. At this point, the element will turn OFF.  
If the water should cool to outside of this temperature range, 

the AC immersion element will again be energized and will 
continue until either the AC circuit breaker is placed OFF or 
the temperature range is again achieved.
