2:05
going to your system we have ball valves
2:08
there so you can shut off and isolate
2:09
that manifold on the other end of the
2:12
manifold we have an air vent on the
2:14
supply and return side and an auto air
2:16
vent and we have a boiler drain yup on
2:20
under both both sides so you have a way
2:23
in and a way out right with garden hose
2:25
connections so if you look at it the
2:27
only thing connecting the top manifold
2:29
to the bottom is the pecs between it
2:31
right exactly pecs between it and the
2:35
beauty of our our manifold too is you
2:38
got isolation on both sides you can shut
2:40
off on the 668 S1A’s you can close off
2:43
the balancing valve side and you can
2:46
also shut off the return side right
2:47
right so you have a complete isolation
2:50
of that Loop you can isolate all loops
2:52
and start with one Loop and and open
2:54
them up one at a time right so whether
2:56
you're filling from the boiler side I
2:59
mean that's one way you can do it Greg
3:00
mentioned that when I filled systems a
3:03
lot of times I use the boiler fill to
3:05
flush them sure folds sure yeah you put
3:07
it you put it in bypass mode and let
3:09
that that fast fill feature take over
3:11
and and do what it does right and when I
3:15
did that typically I would shut the
3:18
return ball valve off on the manifold I
3:21
would connect a hose to the drain on the
3:24
return side of the manifold and then I
3:26
would fill that manifold through the
3:28
boiler supply side coming in and that
3:31
would bring it into the top supply side
3:34
manifold through the tubing back into
3:36
the return and then out my hose that was
3:38
connected to that drain
3:40
and it worked well I mean it can take a
3:43
little longer because like Greg
3:44
mentioned you know you you know you're
3:46
filling from the boiler side yeah so you
3:48
have all the near boiler piping to go
3:50
through and possibly the boiler
3:52
depending on where where things are
3:53
situated but you gotta make it through
3:56
all of that first then to get to the
3:58
manifold right yeah and typically when I
4:00
did that I would you know I would open
4:02
up all my all my circuits and I would
4:05
just start to flow water through that
4:06
manifold and it takes patience it does
4:08
take time and I would have my hose open
4:10
and I just start getting that water
4:12
moving through it and then once I had it
4:14
moving through the manifold I would shut
4:17
down all of the ports on the return side
4:19
sure except one yeah and I would Purge
4:22
that Loop and then I would open that one
4:24
and I would close that one and open the
4:26
one next to it and I'd work my way
4:28
across the manifold that's perfect yeah
4:30
it takes time it does purging does take
4:32
a lot of time it's a very tedious
4:35
process and no matter how you like to do
4:38
it I mean
4:39
I'll mention my favorite way of doing it
4:41
yep just you have those isolation ball
4:44
valves on the inlet and Outlet side of
4:45
the manifolds
4:47
close them off and then I would say hook
4:51
in a garden hose right to
4:54
the return
4:56
the return manifold on the bottom of
4:59
that that purge valve and then either
5:02
hooking it to
5:04
the flush cart and demineralize water or
5:07
if you have another water source a
5:10
washer hose if you've got a
5:12
slop sink close by that's got garden
5:14
hose connection that's a quick way to
5:16
fill it's a good resource it is I mean
5:19
you're even a hose bib if if you yeah at
5:22
all costs you always have a hose baby
5:23
you can grab to
5:25
right to run but you have a way of
5:27
running water in the supply side and
5:29
again by isolating off the loops and
5:32
opening them up one at a time running it
5:34
until
5:34
you see
5:36
month of pure water coming out you're
5:38
done getting burps of air
5:40
close that off and move on to the next
5:42
one and repeat that process over and
5:44
over until it's completely purged right
5:46
so that's a great option I mean I was
5:48
filling from the system side of the
5:50
manifold and you like to isolate it and
5:52
fill from the drain valves yeah
5:55
essentially bringing water in through
5:57
one of the one of The Purge points and
6:00
then removing water from the other and
6:02
you mentioned what I like with your with
6:05
your option is that it's a great way to
6:07
hook a demineralizer up and and improve
6:10
the water quality of what you're what
6:12
you're putting into your system right
6:14
yeah rather than pumping a whole bunch
6:16
of system water especially if you get
6:18
hard water right you know this is this
6:21
is always a hot topic of a discussion
6:22
too is water quality yeah and you can
6:25
never have
6:26
enough good water in the system right
6:28
well exactly and then when you when you
6:31
look at it you know they're because
6:33
water takes that path of least
6:35
resistance it just takes time so that's
6:37
why you know you mentioned you like
6:38
doing it I like doing it closing off
6:40
once all the circuits except one and
6:42
purging each one individually and then
6:44
once you get them flushed out well and
6:46
you put that system into operation you
6:48
count on your air vents on the manifolds
6:50
to take over and and provide the rest of
6:52
the purging
6:54
right exactly
6:56
well
6:58
you always need a way of pumping water
7:01
in doing it the way I like it and say
7:03
say you don't have a garden hose
7:05
connection but you have
7:06
you end up you can bucket water in or
7:09
whatever it might be but if you have
7:11
that fill and flush cart that we build
7:13
so many of
7:15
that's a great Shameless plug for that
7:17
product right but that thing's nice you
7:20
you have everything you need right there
7:22
pump hoses you can you can hook that
7:25
thing right up to a manifold fill the
7:27
hopper you know fill the tank full of
7:29
hopefully demineralized water or if all
7:31
you've got is sight water then you do
7:33
what you have to do
7:35
fill that up and let it pump right you
7:38
can let that run for a while and you'll
7:40
pull that air out through that film
7:41
flush cart right and any debris that
7:44
might be stuck in in the tubing you know
7:47
if it was if it was run during
7:48
construction sand dirt someone ripped
7:50
the tape off or pulled the plugs off of
7:52
it or whatever
7:54
there's good chance there might be
7:55
debris in it so that fill and flush cart
7:58
is really handy to be able to take the
8:00
dirt and debris out of the tubing rather
8:01
than hopefully not get it stuck in the
8:03
manifold it sure is and then also
8:06
um by using the pump you're raising the
8:08
velocity of the water through the tubing
8:10
so you're going to get that air to move
8:12
you're going to keep that air moving a
8:13
little easier than you would it would
8:15
just uh Street pressure water sure yeah
8:17
yep yeah you get a lot more a lot more
8:20
velocity and movement that way yeah and
8:21
then again you remember once you put it
8:23
in service you have your your air vents
8:25
on the manifolds that that will take
8:26
over and finish it you're not going to
8:29
get every inch of air it's so tough to
8:31
get every bit of air but the air vents
8:33
are there to help you with that any
8:35
little bit that you missed say it gets
8:37
caught in a high Spot somewhere in a
8:39
manifold and you can't quite get it to
8:40
flush out it'll work its way out yeah it
8:43
will
8:44
so that covers our 663 and 668 we have
8:47
our 172 mixing manifold and I've got a
8:49
number of questions on that as well
8:51
that's always a
8:53
point of curiosity for a lot of people
8:55
because they see it and it's it's our
8:58
668 S1 manifold but then we combined a
9:01
mixing station that includes a hydraulic
9:03
separator a mixing valve and
9:07
an elbow and pump right and on that
9:10
elbow you do have a manual Purge vent
9:13
the pump and the pump you can either get
9:17
it with a high efficiency pump I think
9:20
it's the alpha alpha grundfos alpha pump
9:23
or the 1558 three speed two options
9:25
right and then
9:28
you have the option to either keep the
9:30
hydraulic separator or that H fitting in
9:32
there which has a check valve in it or
9:34
remove it and that's another question we
9:37
get a lot of too yeah when do you leave
9:39
it and when do you remove it and it
9:40
really depends on how your systems pipe
9:42
before the manifold if you're counting
9:45
on that pump in that manifold to be the
9:47
The Zone pump or system pump as well as
9:51
the manifold pump then you're going to
9:53
remove it exactly if you have another
9:54
Pump In Line Pumping to the mixing
9:57
manifold then you're going to want to
9:59
leave that in yup that that age fitting
10:01
stays in to prevent the pump conflict
10:03
right but easy enough to to remove in
10:05
the field but when it comes to Flushing
10:07
and filling that that one can be a
10:09
little bit more challenging right with
10:11
with that H fitting in even when you
10:12
have we have isolation valves below that
10:14
H fitting if you close them off guess
10:16
where the path of least resistance is
10:18
now it's through that H fitting yeah it
10:20
is so and well and because it has a
10:23
mixing valve in it the return side from
10:27
the Y water coming back from the tubing
10:29
is going through the mixing valve and
10:31
also back to the return so if you have
10:33
that H separator in there it can
10:36
go down and through that H separator and
10:39
back up the supply side and you can run
10:41
a loop purging purging just the manifold
10:44
without the tubing so that's where you
10:47
really need to you know work with the
10:50
valves on the manifold to isolate each
10:52
Loop and and you know I like Greg's
10:55
method in this manifold specifically
10:57
because bringing water back in up on the
11:00
supply side pulling it out on the return
11:02
side through the the drain ports yup
11:06
kind of isolates your boiler feed so you
11:07
can shut those valves off right at the
11:09
manifold yep having a transfer pump and
11:12
even if you don't own one of our cool
11:13
carts having a high head pump that you
11:16
can move a lot of a lot of velocity with
11:19
with the bucket and hoses just like you
11:21
know sometimes we had do in the field oh
11:24
yeah
11:25
um yeah unfortunately I wasn't lucky
11:26
enough to have one of them now me either
11:28
a cart or a bucket or hoses it was
11:31
always you're using whatever water's
11:32
there right so
11:34
it's it's very important to on the 172
11:38
to definitely
11:40
Purge through the drain valves it just
11:43
it works so much better I think it does
11:45
and I think I would say with that
11:47
manifold
11:48
um it's going to take a little bit more
11:50
patience with purging it because of that
11:52
of that mixing valve in place but
11:55
certainly certainly easy enough to do it
11:57
just takes a little bit more time and
11:58
patience yeah patience is key with
12:01
anything yeah anytime you're doing
12:03
hydronic work it takes more time
12:06
it absolutely does
12:08
well I think we covered that pretty well
12:09
yeah quick little snippet but boy we've
12:11
been getting calls on that recently when
12:13
guys are starting to fill systems and
12:15
get them ready to run this winter so I
12:16
thought I thought maybe that would be a
12:18
good thing to jump on and talk about
12:19
yeah hopefully it's helpful and
12:21
eventually I think we're going to put
12:23
together a YouTube video and I don't
12:24
think I know yeah we are we are going to
12:26
put together a YouTube video on on the
12:29
steps to take and and purging one of
12:31
these manifolds so you'll find that on
12:33
our ask Luffy blog yes we'll post a link
12:36
