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.

What is the difference between this tube heater and straight tube heaters?

The PBF (Bigfoot) is a U-Shape heater instead of the traditional straight.  This poultry model is different than the industrial U shape heaters due to the special designed brackets that holds the reflectors at a specific angle outwards.  This allows for a more even heat pattern that is wider then with the straights.  Also the PBF comes in smaller BTU sizes to decrease intensity directly below the heater for houses with lower ceiling heights.  The straight tubes have a tear drop pattern with majority of the heat coming out the first half of the heater.  The PBF (Bigfoot) was designed to address these specific issues and provide a wider more uniform coverage.

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.
