I found that the pump was
bad on this Peerless boiler. So Now I will show you how to replace a Taco 007 circulator Pump.
Make sure the power is off. You can't trust the switch at the boiler and
breakers and fuses are almost always marked wrong. test the wire it's self to
be sure the power is really off. Please note, all images are thumb nails, just click on them to see a larger image.
This is the old one, See all the rust along the back of it. The boiler
needs to be drained first, so turn off the valve that supplies water to the boiler.
Then hook up a hose to the drain at the bottom of the boiler. On this boiler it is on the right side but some of them are in the back where you can't reach them. What a pain this can be.
Now that the water is drained. you will need two wrenches 1 5/8" ant the
other 11/16" most pump bolts are this size. Sometimes the bolts will not
come loose and you have to cut them off. And in this very tight working area
that can be a real Bi__h

with the two wrenches loosen and remove all 4 nuts and bolts. then lift up on
the pipe a little and pull the pump out.
Remove the screw remove the wire cover. Again Make sure the power is off. there
are only two wires one black and one white or yellow. remove the 2 wire nuts.
they should just un screw.
Remove the wire guide And through the old pump away.
Taco 007 Pumps Have a direction of flow. Indicated by the arrow stamped on the
back of the pump As a rule of thumb the pipe that goes into the boiler at the
lower point is the return line and you want to pump the water from the house to
the lower part of the boiler. In this case you want the arrow facing down
Because the pump in on the return pipe of the boiler.
Another problem, The old pump had the power supply box on the right
(with the arrow pointing down But the new one has it on the left I can not
install it this way because there will be no way to get to the power box with
out removing the pump. So I have to spin the
motor.
There are 4 little bolts on the front of the pump remove all 4 then turn the head 180 % and pump the screws back make sure to tighten them down evenly
Now it is facing the right way
Now put the wire guide on the new pump and tie the black wire to the yellow
wire in the pump and the white or yellow wire to the white wire in the pump put
the wire nuts back on Make sure they are tight and no wire strands are showing.
put the cover back on and put the screw in.
Now put the rubber washers between the pump flanges make sure they do not get
pinched and put the 4 nuts and bolts back and snug them up good but don't make
them too tight and don't tighten one side more then the other. Now you have to
fill the system with water and make sure you don't have any leaks. Then you
will need to get the air out of the system
This is for gas fired boilers only I will be adding oil fired soon.
How do I know, If it is my pump that is bad? This is not a simple question.
because allot of things could be the cause of a pump not running. and there can
be many other reasons that you don't have heat.
This
may

more
then
you
should

to
do
on
your
own.
