The 1st

@ August 28, 2014 5:36 AM in why these two adpaters' price difference is so big?

The 1st one looks like a Street fitting... goes into another copper fitting to be soldered, the 2nd fitting is bigger and tubing goes into it.

You can use either depending on your application.

Why doesn't the price of the 90° bother you? ;)

I think....

@ August 24, 2014 11:53 AM in you will go with one-pipe monoflo setting or two-pipe reverse return setting?

if you plan on using the existing piping, the reverse return will be easier and cost less than adding mono flow tees.

wrap some fins with aluminum foil. They need air flow from the bottom to the top to work, and covering them up will be almost like removing them.

After you decide how much works you can then cut off the fins permanently.

@ August 4, 2014 6:20 AM in choosing (1) Integrated Boiler Hydro-Air and baseboard, vs (2) Separate Furnace and Boiler

I will 2nd what he said. If that were my own house it would be one boiler heating up an indirect heater, the baseboard heat and go with hydro air instead of the furnaces. You'll have to have heating water lines run to the hydro units as well as thermostat wiring back to the boiler.
If your furnace is in the attic, most installers won't put in high efficiency due to the condensation that will form from combustion and the possibility of it freezing in the winter, so your stuck with an 80+ furnace with B-vent flue.

You certainly....

@ July 6, 2014 7:23 AM in Rinnai r94ls Tankless and Propane?

You certainly can run it off either LP or Nat. You will have to call Rinnai and order the correct conversion parts from them which will not be a problem.

I have done it a couple times. It will also come with a new sticker stating it's now LP.

Whats the error your getting?

The aquastat

@ June 10, 2014 6:26 AM in steam in the summer!

The aquastat in the indirect heater controls the temp in that tank.

It needs to also have an aquasat installed in the boiler (below the water line) which takes the boiler water temp and will control the burner by breaking the end switch to the burner. Turning the burner on and off before making steam. It is not something I believe the factory would include on the boiler.

Something like a Burnham 100189-01 High Limit Aquastat

The pressure trol CAN NOT control this... it operates off pressure. If you have any pressure it ran it too long.

You need an additional control ON the boiler which operates off temp. for hot water.

Here is one....

@ April 11, 2014 11:30 AM in New Circ Pump Flange 90 Degrees Off

you want to cut the flange so the cut is the same direction as the piping connected to the flange. Parallel to the piping.

Cut from the outside inwards to the threads. You could also use a hand grinder with a cut off wheel. Cut in the thinnest part of the flange, most likely right in the middle, between the two bolt holes.


@ April 11, 2014 8:33 AM in New Circ Pump Flange 90 Degrees Off

the old flanges can be a bear to remove by unscrewing.

I use a sawzall make a slice from the outside to the threads. Get it as close as you can and then unscrew it. Piece of cake.

I also have been putting aside making an order for a couple of new reads from here..

I have the Lost Art of Steam heat book, it alone will keep you busy for quite a while. Tons of great info in there.

Have a good trip


@ April 1, 2014 5:38 AM in Tankless brand

We've mostly installed Rinnai. Have quite a few out there, both in residental and commercial.

Recently we have been getting the Error 79 (internal water leak) code come up on the newer ones during a heavy rain storm.

Seems like rain is finding it's way down the intake pipe from the roof termination. It leaks out of the combustion fan motor into the bottom of the heater and the sensor goes off.

They have been a good little heater for us besides that.


@ March 31, 2014 11:21 AM in Modcons in Closets-

This is what's going on, now that we have a model number.

IN the install manual,

the model 055 can be installed in a closet or alcove.

A closet is a room the boiler is installed in that has a volume less than 90 Cubic Feet ( for the 055)

If this is SO, then you have to use either CPVC, Polypropylene or Stainless for the vent material due to amout of heat generator in the room.

No air ventilation openings into the room are needed when clearances around the Knight boiler are at least equal to the Service clearances shown in the manual.

For spaces that do NOT supply this clearance, provide two openings as shown in FIG 1-1

The openings are not for combustion they are to cool the space.

The issue you are having with the boiler not firing over 60% has nothing to do with this.

Parameters are controlling the firing rate.

@ March 20, 2014 6:43 AM in Piping correction 1 inch copper sweat

When you have an odd angle and you want to get back straight, you have to make a swing joint using 2- 90°. It can be done with tees as well.

The first is positioned either: 12,3,6, or 9 o'clock, the 2nd 90° will get you straight. I agree about all the fittings there.

You can also do a heat bend if it's off by a little.

In my opinion

@ March 18, 2014 4:30 PM in Steam radiators without bleeders for hot water system

In my opinion, if you don't tap every section and vent each one I think using it is a terrible idea.

The heat you will get out of them will be nil compared to being full of water. To wait months for them to possibly bleed out with water is a very, very poor installation design.


@ March 4, 2014 5:03 PM in BTU Radiator Output? (see attached photo)

it's NOT a radiator. It's a Wall Convector.


@ February 7, 2014 5:49 AM in Modine HW Unit in Garage

I feel a set up like that is going to end in one of two scenarios:

The zone stays off most of the time, even if you'd like to use it , just too much work to hang in the garage for an hour or two.


The zone freezes and splits a line cause it gets left on.

How cold does the garage get? ever put water out there and see what happens thru the years?

You might be better off adding glycol to the system and not worry about it.

@ February 4, 2014 6:25 AM in indirect tank

give people prices for both the indirect and new coil. I favor the indirect by a long shot. Does your coil have bolts or studs holding it to the boiler? IF bolts there's a good chance some may break off when trying to remove them. Then it's drill and tap time.

Can be very time consuming. Tankless coils will consume more oil, and will give you less hot water than the indirect, but will most likely cost less to replace it.

I have an indirect off oil, in the summer time my boiler will get down to room temp before the indirect fires it up again. Tankless is going to keep that boiler 160°-180° all year long, day and night.

If the tankless gasket is leaking then it has to come out to replace it. If it's leaked for a long time, the leaking water can actually carve a groove in the surface of the cast iron boiler and make the new gasket have a difficult time sealing.
