Heater  Operation  

Starting The Heater

Note: 

It is important to understand that this heater does not simply turn on and turn off. Rather, it has a 

sophisticated operating system similar to a household furnace to provide reliable heating comfort. The 
operator should familiarize themselves with the normal operation of the heater. 

Start Up

1.  Systems Check Phase

•  When switched on, the heater conducts a self check.
•  Component integrity (Glow Pin, Blower, Fuel Pump, Flame and Overheat Sensor)
•  Voltage (Must be with 10.5-16 volts)
•  Upon satisfactory systems check, the heater will continue to the Preheat Phase.

2.  Preheat Phase – Glow pin will switch on to preheat for 50 seconds.
3.  Ignition Phase – Fuel and combustion air are slowly introduced to the combustion chamber and flame is  
 

established typically within 2-3 seconds.

4.  Stabilization Phase – To further establish combustion, the glow pin remains on and the fuel / air mixture  
 

is slowly increased. The flame sensor monitors the increasing temperature at the heat exchanger    

 

(Typically 2 ½ minutes).

5.  Running Phase – Once the flame is established, the glow pin will switch off. Incoming fuel / air will be  
 

ignited by the established flame inside the combustion chamber.

Running Mode

The heater is designed to function in two different operating modes. Refer to the Operating Switch 
Instructions for details.

“Power Mode” 

Controls the heat output level.

The operator can adjust heat output level in a range from 1.4 -5.0 in 0.1 intervals.

“Automatic Mode”

 Establishes target cabin temperature for heater to maintain. 

(Primary operating mode for cargo and cabin heating applications)
Target temperatures range is 10º C to 35º C (1º intervals) 

Note:

Internal temperature sensor inside heater is used to regulate the cabin temperature.
Temperature displayed on switch, only reflects temperature at operating switch.
We recommend the use of return ducting (ducting on both ends of heater) for best temperature 
regulation
