UV Sensor Retrofit Instruction Manual for Portable Dryers Product Description The UV flame detection kit was designed to replace the flame rod or probe that is used on Vision dryer controls that utilize the HF-4624 fenwal flame control board. (See Figure 2.) This flame controller uses a flame rectification circuit that in certain situations may not work reliably with certain gases.

UV Sensor Retrofit Instruction Manual for Portable Dryers Sight Tube Assembly Instructions Locate 1/2" x 5" nipple (THH-4129) and attach the 1/2" coupler (D67-0005) to one end of this nipple. Then attach the 1/2" to 1/8" reducer bushing (007-1149-9) into the 1/2" coupling as shown in Figure 4. (No sealant is necessary.

UV Sensor Retrofit Instruction Manual for Portable Dryers Figure 6 Sensor Location Pointing between Burner Veins Once UV sensor has been mounted to sight tube then attach the five (5) pin cable to sensor. Route the cable through the black plastic heyco cord connector (FH-1310) then through either an existing hole in the fan/heater control box or drill a new 7/8" hole. Try to keep the cable entrance location close to the relay and fenwal board.

UV Sensor Retrofit Instruction Manual for Portable Dryers Wiring Instructions Disconnect power and lock out prior to performing this service. DANGER The factory and the UV wirings diagram are included (Figure 9 on Page 6 and Figure 12 on Page 8) which will help show the difference between the current and modified versions. 1. Cut the supplied red wire into two (2) equal pieces. Strip the insulation off both ends of each wire. Attach one wire between terminals 10 and 11.

It is the thin red 18 gauge high temperature wire (Teflon) and tie it back out of the way. Attach the red wire from the UV sensor cable with the spade terminal attached to the S1 terminal of the fenwal.

UV Sensor Retrofit Instruction Manual for Portable Dryers Operation The UV sensor is highly sensitive to only UVC light that is present in flame. It can detect a small flame from a lit match over 6' away. Because the particular wavelength “C” band of UV light this sensor is sensitive to (180-230 nm) is normally absorbed by the ozone present in our atmosphere the sensor will not be affected by normal sunlight. The UV Sensor is powered up whenever the dryer controls are energized (orange and yellow wires).
