Why write AO Smith?

@ June 20, 2014 1:11 PM in Some days I get a little burnt out

I guess I missed something.... Who ever said you could/should use a water heater for radiant heating...? Don't see anything on their literature.

You are partly correct...

@ December 24, 2013 8:52 AM in wm97+ indirect

The 97+ does use a U-control.... it however is not the same as used on the Ultra series. The 97+ control only has 2 temp priorities... with zoning capabilities for 3 zone.

I would lower the 190f temp. I usually program DHW boiler temp at 170F.

Maybe this will help... fyi.... for your tech:

@ December 18, 2013 12:37 PM in NTI ER6 code in cold weather

“Flame Lock Out”
Sentry has sensed a lack of 24V to the gas valve during operation or a
Fenwal ignition lockout. There is a problem in the ignition sequence, it could be caused by a faulty igniter, flame sensor, gas valve or improper line pressure or combustion. Check ignition sequence to determine which component is not functioning. (Sentry will retry ignition sequence 1 hour after ER6 code originally occurs or if control is reset)
If a 3-Flash error occurs on the Fenwal controller prior to locking out on an Er6,
proceed to “Three Flashes on Fenwal”.

Three Flashes on Fenwal “Ignition Lockout”
Check the condensate drain for blockage – a blocked condensate drain will flood the
combustion chamber and cause this error, see Section 5.0 for further instructions.
Reset and observe ignition sequence:
1. If the burner ignites then goes out within 2-3 seconds:
a. If the boiler is newly installed, check the polarity of the 120VAC power
supply – reversed polarity will cause this error.
b. Ensure the cable is connected to the flame sensor.
c. Check for proper sustained gas line pressure.
d. Check venting and combustion chamber for blockage – clean combustion
e. Replace flame probe.
f. Replace Fenwal controller.
2. If the igniter glows but the burner does not ignite:
a. Check for proper sustained gas line pressure.
b. Check venting and combustion chamber for blockage – clean combustion
c. Replace igniter.
d. Replace Fenwal controller.
3. If the igniter does not glow:
a. Replace igniter.
b. Replace Fenwal controller.

Do you mean TFT...? The TFT utilizes the fire tube type heat exchanger similar to the Triangle used successfully for year. See link for more info:

This may help.....

Boy I'm confused....

@ April 25, 2013 12:40 PM in Alpine MCBA - indirect insltallation

If you don't have an indirect heater.... what's the question? If you don't have a DHW heater what are you trying to do with the boiler DHW priority? Not sure I understand.


@ April 23, 2013 9:18 AM in Outdoor reset

The new standards for residential boilers were passed in 2007 taking effect Sept 1st 2012.

See link:

The new regulations do not say ODR type controls must used, only that "Automatic Means for Adjusting Water Temperature". must be used. Some boiler manufacturers have chosen to use "thermal targeting" controls such as the Hydrolevel.

Any unit manufactured after the Sept 1st date must comply.

Power stealong stats are often....

@ April 3, 2013 3:22 PM in How often should the boiler limit switch be reached?

a problem. See the Honeywell link below:


@ March 19, 2013 8:58 AM in Need some info.

... Why not just use the HeatLink design program.... it will provide everything you need... loop lengths, flow rates, pressure drops, manifold settings, etc. you can download from the HeatLink website. Get the older Excel version.... assuming you have MS Excel on your computer. If you can't get it from website let me know. I have it.... been using it for years.


@ February 27, 2013 2:35 PM in One for the plumbers

RydLyme descaler?

Robert.... I think Heatpro

@ February 11, 2013 4:16 PM in In your opinion- best boiler on the market?

meant the X to be a "variable" in model number to indicate required size... 


@ January 15, 2013 10:59 AM in Can anyone tell me what this component is?

No attachment.... try posting pics again.

Yea... I see what you mean...

@ January 14, 2013 2:48 PM in Dan, Problem with Pics

All the pic links are directed back to the first pic.

I am a little familiar with HeatLink....

@ January 10, 2013 10:02 AM in circulation pump modulation.

having sold them for probably 15yrs. Heatlink Statlink  thermostats and control modules are not conventional providing bang on-off control like a standard thermostat/zone valve controls. They utilize proportional integral temperature regulation therefore it is not uncommon for an actuator to never fully open. From T-stat literature - "Proportional plus Integral (PI) controlled temperature regulation. Proportional moves quickly to the desired setpoint and slows down when the desired setpoint is near. Integral compensates the proportional offset (overshoot) and stays close to the setpoint." For more info I would suggest contacting HeatLink.- google HeatLink Usa and go to "contact us" for your region.   Good luck.

CP number

@ January 4, 2013 2:22 PM in Can anyone tell me what model boiler this is?

from Weil Mclain lookup tool indicates following:

Serial Number (CP)5308099

DescriptionBlr CGt5 PIN T007 S1

Manufactured Date3/6/2006

Part Number381357000

I agree with SWEI.... if your not a service tech.... you may want to get one.

These might help:

QB Manual

@ October 24, 2012 9:47 AM in need some spec's Weil Mc Burner 180

I have the QB manual if it helps.... tried adding as an attachment without luck....

Let me know I can email to you.

Is it....

@ February 13, 2012 3:50 PM in Boiler water testing

haven't used on geothermal...

@ January 11, 2012 9:59 AM in Heating Edge baseboard with geothermal ?

but we have used on quite a few projects.... utilized dual supply piping and saw good results. Used in one great room where wall space was extremely limited due to glass  and got expected results. Also have used on low temp radiant systems where baseboard was requested. Nice product albeit a little pricey.

For info on Honeywell Internet gateway....

@ January 3, 2012 9:28 AM in WiFi Control

check out this link:

This is their internet gateway. I think it can handle 4 "zones" and can be used with any of there wireless thermostats.

Hope it helps.
