The heaters should be serviced every 750 to 1000 hours of operation depending on the usage or; if the output of the heater appears to have decreased from the same valve setting or; if the exhaust exhibits smoke.

The heaters consume about 4000 cubic feet of air per 1 US gallon of oil. This air enters the heater through the air inlets and exits the chimney as combustion gas. They should be installed in a well- ventilated area that allows the entrance of outside fresh air.

ITR warranty covers parts and labour for a period of one year.

Please check the troubleshooting section of your owner’s manual. There is probably too much draft on low or not enough draft on high fire.

Please check the troubleshooting section owner’s manual. This may be a result from blockages in the fuel or carbon and soot build up.

See the instructions for each specific heater in the manual, or under this website’s lighting section. The heater is lit with some starting diesel fuel in the burner base, tissue paper and matches.

It is unusual, but possible. Under some conditions, wind deflectors may be required.

The TREKKER will operate for 80 hours on low-heat setting and 40 hours on high.
The EXPEDITION will operate for 26 hours on low-heat setting and 15 hours on high.
The PROSPECTOR will operate for 15 hours on low-heat setting and 9 hours on high.

The minimum standard clearance between the Trekker and any building construction other than the floor is 16 inches (40 cm). The minimum standard clearance between the exhaust vent pipe and any building construction is 16 inches (40 cm). The minimum standard clearance between the Expedition heater and any building construction other than the floor is 24 inches (60 cm). The minimum standard clearance between the Prospector and any building construction other than the floor is 36 inches (91 cm). The minimum standard clearance between the exhaust vent pipe of both the Expedition and the Prospector and any building construction is 18 inches (45 cm).

The diameter size of the exhaust can be changed on the heaters as long as there is a minimum of three feet of the original size of the exhaust from the heaters’ exhaust outlet. If you are going to change the diameter size of the exhaust it is preferred to increase the diameter than decrease it. The diameter of the exhaust should be decreased only on a temporary basis.

The recommended draft for the Trekker is between .030 -.045 inches water column. This is measured 18” (45cm) up the stack and before the draft regulator. The minimum flue stack height is 6 to 9 feet (1.8 – 2.7m). The recommended draft for the Expedition and Prospector is between .040 -.060 inches water column. The minimum flue stack height of both is 9 to 12 feet (2.7 – 3.6m).

The heater will require a break in period of 1 – 2 hours where residual oils from the paint and manufacturing process will burn off. During this period, some smoke and fumes may be generated from the outside burner case; make sure there is enough ventilation for the smoke and fumes to escape the inside living or operating areas.

Yes. Even though the Pioneer heaters do burn very clean, exhaust all gases outdoors. During operation, the heater produces harmful carbon monoxide (CO) and other gases. To prevent CO poisoning, ensure that the exhaust stack sections fit together snugly and that the exhaust gases are properly vented through the roof or side of the structure and follow the recommended exhaust guidelines.

Yes, the Pioneer heaters can run unattended. However, all heaters, regardless of the type or make, can malfunction and all manufacturers recommend that heaters not be left running unattended. DO NOT leave the heater running unattended. If there is a malfunction, ITR accepts no responsibility or liability for any damage caused, regardless of the type or extent of the damage

No, as this causes a safety hazard and the heater will not burn properly.

Yes but the heaters are certified for diesel only. Please check with your dealer or ITR before using any other fuels. ITR accepts no responsibility or liability for any damage caused by unauthorized fuels, regardless of the type or extent of the damage. Any unauthorized fuels also void the warranty.

Information about the three types of PIONEER heaters is available here.
When calculating requirements for BTU for a defined space, factors such as altitude, structure’s heat retention, insulation, and quantity and size of windows all can radically affect the number of BTU required.

Yes, the Pioneer heaters have been certified to CSA and UL standards, just make sure that the local building codes are followed.

No, Pioneer heaters must be used in a stationary application. The heater’s oil control valve has a safety feature and when tilted it will stop the flow of fuel

Our patented burner cannot flood and there is never a large amount of fuel in the burner base. If the flame should go out the diesel fuel stops flowing into the burner.

No, we have a patented vaporizing burner design that burns diesel vapors and not raw diesel which results in a much better and cleaner combustion.
