Reznor 197117 Kit
The Reznor 197117 Kit is an essential DJ20 high altitude kit engineered for Reznor unit heater models UDAP, UDAS, UDBP, and UDBS (sizes 30-125). High-elevation installations over 6,000 feet require a precise adjustment to the air-fuel mixture to compensate for decreased atmospheric density and prevent incomplete combustion or safety circuit tripping. This OEM replacement part includes a specialized pressure switch, often identified by a purple label, calibrated with a specific negative pressure setpoint to maintain reliable heater operation. By swapping the standard switch for the high-altitude variant found in the Reznor 197117 kit, contractors can ensure the unit is properly derated according to the manufacturer’s technical specifications. This kit is critical for HVAC troubleshooting in mountainous regions where standard pressure switches may fail to close. Professional installation by a licensed HVAC technician is required to verify the valve outlet pressure and ensure the burner flame remains stable and efficient under low-oxygen conditions.
Key Benefits- Ensures reliable ignition and prevents pressure switch lockout in elevations exceeding 6,000 feet.
- Optimizes combustion efficiency by correctly sensing venter motor drafting in thinner air.
- Compatible with a wide range of gas-fired unit heaters, including UDAP-30 through UDAP-125.
- Simple field-installable high altitude adjustment to meet local building codes and safety regulations.
- When is the Reznor 197117 kit required? This kit is mandatory for specific Reznor models when operating at altitudes between 6,001 and 10,000 feet to ensure the pressure switch functions accurately.
- Does this kit include gas orifices? The 197117 kit focuses on the high altitude pressure switch; always consult the unit’s installation manual for specific manifold pressure adjustments and potential orifice changes.
- Can I use this for propane-converted units? Yes, provided the unit has been correctly converted to LP, the high-altitude switch is still necessary to monitor venter pressure in thin-air environments.
