@ 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.
@ June 10, 2014 12:09 PM in Lochinvar ignition troubleWhats the error your getting?
@ 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.
@ May 6, 2014 8:00 PM in bathroom baseboardDon't know if any of your local suppliers stock Haydon... The covers are also thicker than standard and come with a LEC and REC (end covers)
@ April 26, 2014 5:54 AM in Mass Code any oneThe gas codes for MA have not changed yet.
We are currently using NFPA 54 (2002) and NFPA 58 (2001)
They are working on a new code book that will be using newer versions, I heard the end of this year.
@ April 16, 2014 3:28 PM in Painting Cast Iron Baseboard Radiator – Baseray/Governaledepends if you have steam or hot water. Steam requires high heat paint or it will blister off within an hour.
@ April 11, 2014 11:30 AM in New Circ Pump Flange 90 Degrees Offyou 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 Offthe 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.
@ April 8, 2014 5:19 PM in Spoke with Deb at Heating Help todayI 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 brandWe'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, http://www.lochinvar.com/_linefiles/WH-I-O-Rev%20P.pdf
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 sweatWhen 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.
@ March 18, 2014 4:30 PM in Steam radiators without bleeders for hot water systemIn 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 GarageI 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 tankgive 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.
@ January 9, 2014 4:15 PM in Baseboard heat - house won't get above 60and unless it is making hot water, then it IS responding from a call for heat or else it wouldn't be running.
The " internal thermostat" is more commonly called a Hi-limit. Your boiler is now bouncing off Hi limit and not dumping it's heat off.
Sounds like you have flow issues, bad circuilator or air in the zone.
If the thermostat hasn't recently been messed with.... and it has good batteries (if it has them) then it's 98% not the issue.
@ December 2, 2013 8:16 PM in Boiler Nozzle conversion - Help!You can't just swap out the nozzle.
Ok to clarify... a furnace is forced hot air... a boiler contains water and can be hot water or steam. It is confusing when you use both terms together, what do you have? and if a boiler is it hot water filled or steam?
You will most likely be able to buy a gas conversion burner, which will bolt up to your existing boiler/furnace, but they ain't cheap, and I wouldn't recommend it on an older unit.
@ November 1, 2013 6:06 AM in Knight boiler problemsconfirmed there are no obstructions in either the intake or exhaust piping? I really don't like the wide open exhaust with no screen on the outlet.
We have always used the factory termination kit that comes with the boiler. Last year had a bad vibration from the fan motor, spinning out of balance getting an error code.
Disassembled it to find a mouse in there all smashed up. He ate thru the plastic grate of the factory termination and found his way to the combustion fan.
