Product Description

?

This is a photocell designed for use in space heaters to detect the presence of a flame, ensuring that the burner ignites and remains lit to provide heat while preventing the release of unburned gas. This photocell is a genuine OEM part, sold individually, and is compatible with various heater models. It is typically attached to the main combustion chamber with a bracket (sold separately). Factors like dirt and debris, aging, and exposure to higher temperatures can lead to photocell failure. A failing photocell can result in your heater not starting, starting intermittently and then shutting down, and sometimes displaying error codes related to the photocell. To replace this part, you will need a screwdriver and/or socket wrench, as well as a set of pliers. Begin by disconnecting the heater from its power source and draining the fuel from the heater. Remove the top, back, and side covers of the heater to access its internal components. Locate the photocell within the heater, disconnect its cable and the photocell itself, and then install the new photocell. Reassemble your heater, ensuring that any disconnected wires are properly reconnected.

Disassembly of the unit is pretty straightforward. Just seven sheet metal screws if I remember correctly. The only problem I encountered was that the nipple on the new fuel filter was the larger diameter than the old filter. The new fuel line purchased also has a much larger diameter to accommodate this. Unfortunately the unit was getti ng too much fuel after I completed the repair. It was not running properly. I went to the local hardware store and purchase the smaller diameter new fuel line and was able to stretch this over the larger nipple of the new filter. It runs perfectly again.

Heat Stream 70T 70K Btu;
Removed covers, replaced CDS photocell, on-line information shows replacement part # -1000 was a replacement, however, was incorrect connector; CDS cell leads soldered / spliced to original connector; problem unresolved, same as with original cell;
Discovered CDS ranging resistor R12 had changed value providing a marginal out of range voltage to the RISC processor input while operating. Padded 5V B+ resistor by adding 2.5K ohms; operational voltage to RISC input lowered from 2.4V average to 2.1V average while flame active; system now operates correctly. System checked for correct shutdown when optical path blocked simulating flame out condition.

Removed top cover(s) and side covers , removed flame detector wires from drive Board , pulled wires through the lower cover and the flame detector bracket. Reinstalled all parts as needed. Don\'t fire up the heater with the top covers off it will trick the heater into a fault because of not enough air through the combustion can.
