Detroit Radiant TP-36NKIT Heaters Kit

The Detroit Radiant TP-36NKIT is a comprehensive OEM replacement kit engineered specifically for NG DTH(S) Tube Heaters. Designed for professional field upgrades or repairs, this kit functions as the primary solution for replacing the legacy TP-36 (WR 25K) Valve. The assembly includes a TP-107 Natural Gas Valve (pre-set at 3.5" W.C.), a TP-78D Circuit Board, and the necessary TP-78B wire harness with a TP-390 adaptor. This integration ensures seamless electrical communication and gas flow regulation within the burner box. Note that this is a technical repair kit and is not for gas conversion purposes. For a complete system overhaul, verify if the inducer fan or pressure switches also require the TP-CPA series upgrade, as this kit focuses on the core ignition and valve control logic. Technicians must remove the TP-33 external regulator during installation, as the modern logic no longer utilizes the external sensor for flame sensing.

• OEM Compatibility: Guaranteed fit for Re-Verber-Ray DTH and DTHS series infrared tube heaters.
• Simplified Integration: Includes the TP-390 circuit board adaptor to align new control logic with existing wiring.
• Precision Gas Regulation: The TP-107 valve provides consistent manifold pressure for optimal combustion efficiency.
• Streamlined Repair: Consolidates critical ignition components into a single part number to reduce diagnostic and procurement time.

Is the TP-36NKIT used to convert a heater from Propane to Natural Gas?
No, this kit is strictly a replacement for existing natural gas tube heater components. It is not designed or rated for fuel conversion.

What happens to the existing flame sensor and external regulator?
The TP-33 external regulator must be removed. While the electrical wires to the external sensor are disconnected, the sensor itself should remain in the tube to maintain structural integrity.

Does this kit resolve issues with an obsolete inducer fan?
This kit replaces the gas valve and control board. If the inducer fan or pressure switches are failing, you may also need a TP-CPA kit to complete the burner box restoration.
