HVAC/ HYDRONICS By George Lanthier* A Couple of Tips T Figure 1 Figure 2 Figure 3 Figure 4 36 his article may not contain anything new to many of you, but it still contains a couple of tips that may get you out of a jam at night or on a weekend. As with a lot of my articles this one has been adopted from our five-volume set called 'WIRING & Fuel Burning Equipment.' One of the oldest problems has been what to do at night when the burner control or "cad-cell" portion of Honeywell's R8182 control fails. OK, so it's a WhiteRodgers 6C93. But let's just say that you no longer want to use the cad-cell portion and prefer to use a separate control or they have switched to gas using a powerburner, gas or oil that uses its own control. You go out to the truck and guess what, no R8182. Well, here's what you could do. In Figure 1, is the triple-acting aquastat portion, or "white block" of this control. After making sure that power is off, you do the following: Remove the yellow wire from the block, and insulate it with a wire nut, or tape — or both. Remove the wire going to the terminal marked "B1" and secure the terminal screw. Then, put this wire into the hole where you removed the yellow wire. If you have to extend it that's OK. You can put a piece of wire into the "block" and connect it to the "B1" wire with a wire nut. Move the yellow "F-F" cad-cell wires from the R8182 to the replacement control that you will now mount on the burner. If it is a gas conversion these can be totally removed. Rewire the replacement primary or operating gas control into the burner circuit, and that's it! JANUARY 2014 | FUEL OIL NEWS | www.fueloilnews.com Another situation is where you have an R8182 with a remote sensor and well, the infamous R8182H. Well, today you have all kinds of options with remote bulb capabilities. You could use an AquaSmart from Beckett, a Honeywell L7224 or a HydroSmart or HydroStat from Hydrolevel. Replacement of the R8182 has never been simpler and if you do it now it just might save you some time and grief the next time you service this customer. So as usual, you can see that everything always goes back to one of my favorite sayings, "90 percent of your chances of fixing something are based 100 percent on who installed it." Did you know that the thermal sensor on a Beckett AquaSmart can be extended just using a regular telephone jumper wire, Figure 2, and in Figure 3 is an example of an AquaSmart with a GeniSys control pre-made for these change overs and at a fraction of the cost of a new R8182H. My next tip is on the fastest way to find a "short circuit." As we know, a short circuit is when any power-side or "hot" part of our circuit comes into contact with our neutral side or ground. We all know what happens, a blown fuse or a tripped breaker. Always reset the breaker or try one fuse, once. After that, don't use a case of fuses — go to the light! Replace the blown fuse with at least a 100-watt light bulb. If it's an old style service board screw the lightbulb right into the fuse socket. It will fit, because standard fuses and lightbulbs share one thing in common, they both use "Edison T bases," Figure 4. If you have a circuit breaker, place
