How to hook up becket oil furnace

Hey Clinton ,if you have a home style becket no return line is required if you have a carlin the return line will be on the right side of burner pump in coming oil will enter left side next to air bleeder on pump, im worried are you modifying something ? i'll be glad to help if I know what your doing or trying to do.

The standard color code for the HVAC is as follows....
Red=Hot or 24v
White=Heat
Green=Fan
Yellow=A/C
White 1=secondary heat.
Blue=Spare
Orange=Heat Pump
C=Common
The thermostat has the terminals marked R,Rh,W,G,Y.
The furnace should have a terminal strip with similar markings.
If you only have 1 control transformer this will be easy.
Hook the wires up using the colors I have listed. If you don't have the same color wires go with whats close to them....such as use Orange for Red etc. It really doesn't matter as long as they are landed on the same terminals on the thermostat and furnace. Two wires running to A.C unit outside put one on Y the other on C. If you need any more help let me know!

Actually, there is a bleeder valve on the pump you are referencing. It's located directly on top of the pump and the air (with some oil) comes out the nipple looking part just below and to the left of the bleed off valve 1/2" nut.

Your question is quite wide open to interpretation,Size, venting option, space availability,,,,But, if i think you wish to install this in a ,,lets say 1500 sqare feet home,, i would say a oil furnace made by olsen. Burns clean, effeciency depends on model, but sometime i would sacrifice a half % of efficiency for reliability, ease of maintnance,(not enough good ,reliable technicians in this field) quietness, odor free,parts availability, life span, ect ect.Stick with a canadian or north american made oil burner. I aint too fancy on the riello burners or even worse, a burner made for 50 different furnace model. I like the becket or aero burners. Choose a dc fan motor, direct dive if available. Stick with a chimney versus a direct or power vent.

Is your wiring where it's hooked into the furnace still identifable as to color. If so one way to tell whats what is to remove wires from furnace one at a time and disconnect all wires from base of thermostat. Use a ohm meter and one very long test wire. Hook to known wire on one end and use test wire to check wires on t-stat end. When you read closed circuit reattach wire to furnace and lable t-stat end as to color. Connections on base of thermostat should be marked with R,W,G,and y. Check each wire one at a time and when you know what color each wire is hook t-stat base back up,put cover back on and check out. A much eaiser way if you can identify wire color and existing wire is accessible in basement or whever your furnace is . Discconect wires from furnace and see if you can pull wire back up to thermostat. If you're lucky they won't be stapeled inside wall. If you can move wire easily buy approximate length of new wire at hardware store. Most of them will sell wire by the foot. Strip about 3/4 inch of insulation from each wire and twist all wires from old to new and wrap all of it with electrical tape. Carefully pull new wire to t-stat and connect there and to furnace. Good luck. I hope this helps. Thanks

Try and jump it out by taking the wire hooked to R and W terminals on your thermostat and connecting them. It could be you have a bad thermostat.

In order to hook this up to the fan on your furnace, you will need to either have or install a Fan center @ the furnace. (Unless it is gas, and has a circuit board that will simplify the process) All this is, is a transformer, a relay, and a set (or two) of NO and NC contacts. You will need to run 3 wires from the thermostat back to the furnace, if you do not have them already. If you have a gas furnace with a circuit board then all you have to do is connect the three wires from the thermostat to the board. (R to R; W to W; G to G. If you are using an older furnace, or a oil fired appliance, power should go out of the transformer (secondary side) to the thermostat on R. It should then come off W and another wire off G back to the furnace. Connect to the appriately marked terminals on the fan center. Hope this helps

Depending on where the wires were connected on the old thermostat, would be the best place to start, but if that is not an option you could try to trace the wires back to your furnace and see where they connect to. It appears you have either an oil fired furnace, or a single stage heat pump. If you need more assistance please just provide type of heat used. Hope this helps

Do you think it might be the relay switch
