  • Can be used in a vented or indirect (unvented) mode. Available in either natural or propane gas models.
  • Optional Cold Air Stopper™ stops cold or hot air from entering the poultry house when the heaters are not in operation and helps to reduce sweating problems. (Not available on the 150,000 BTU/Hr. model).
  • Includes TISS™ (Tube Integrity Safety System) – Space-Ray’s patented, innovative safety system. In the unlikely event of a tube failure, TISS has been designed to automatically shut off the heater, providing greater safety and peace of mind. See detail below.

TISS

Tube Integrity Safety Shut-Off System

Space-Ray’s patented innovative safety feature for positive pressure radiant tube heaters is called the “Tube Integrity Safety System” (TISS™). The revolutionary TISS™ uses a simple principle to place an electrically insulated aluminum wire in tension above the reflector as shown above.
Low voltage is then continuously passed along the wire in line with the gas control circuit. If heat levels increase due to heat exchanger failure, the wire melts and the safety circuit is broken, breaking the 24 volt circuit and shutting down the heater.

Product Documents
Why is it a lot hotter at the burner end then at the exhausting end?

This is normal to have majority of the heat come out the first half of the heater. This is due to the efficiency aspects of the heater. To ensure that we convert as much of the gas energy to radiant heat we make sure are stack (exhaust) temperatures are under a certain temperature. So by natural laws of physics there is no way to increase the tube temperature at end of heater without also increasing the stack temperatures and losing more energy out the end of the heater. The max stack temperatures we abide by is from CSA which is a certification organization that our heaters are certified through.

How many of these heaters do I need?

The quantity depends on many factors including location (outside temperature), house size and construction, ventilation and type of bird being grown. SpaceRay can help provide a recommend layout with quantity and spacing based off obtained information.

How are these heaters controlled?

The PBF (BigFoot) can be controlled though the line voltage side or 24V connection for a single stage model. For the Two Stage models it can only be controlled through the 24V connection only. These models can be controlled house controller or a thermostat. For 24V control, relay kits will be needed if using one thermostat per multiply heaters. If there is only one thermostat per heater then no relay is needed. For single stage heaters on line voltage control do not need relays.

What is the two stage and how does it work?

The two stage models have a low fire and a high fire. The high fire is the heats max output while low fire is approximately 60% of the high fire. The controller or thermostat will dictate weather the heater is in high or low fire. Usually it will have a call for heat on low first then it will go to high fire if the temperature is not satisfied in low.

What do the lights mean/ what should be on?

The heater has 2 indicator lights (for single stage and 3 for two stage) on the bottom of the burner box and during normal operation both should be on (for two stage all 3 or one Amber and the red). The red light indicates that the air switch is closed. The amber/orange light indicates the gas valve operation. So singe stage when the amber/orange light is on the gas valve is receiving 24V and there for should be open and flowing gas. On two stage there will be two amber/orange lights and one is the low fire and the other is high fire. Both will be on when the heater is in high fire and only the low fire one will be on when just low fire. When there is a call for high fire upon the start of the heater it will just have the high fire light on until the heater actually tries and light then it will light up the low fire. If just the high fire light is on and nothing else is happening then heater is in lock out or control connection is wire wrong.
