Dial size x 3600/seconds= cfh(cubic feet per hour)
He should have a combustion analyzer to check for CO if input is change after the initial start up . ALL POWER BURNERS NEED TO BE CHECKED FOR CO PRODUCTION and good draft !
 Note: all CO detectors have sensors that last only 5 or 7 years.

DV 100 UTICA BOILER

I cannot reduce the input to this boiler.
I not sure but wouldn't  I wire the reset in the low voltage side of the boiler  ( in series with the  limit )?

Reason for primary/secondary

@ June 16, 2010 9:08 PM in Primary/Secondary & outdoor reset ,indirect+zone valves

Reason for primary/secondary is, It short cycled and I tried to eliminate it. What is the the best way to wire the system as it is now?

This is what the system looks like.

Primary/Secondary & outdoor reset ,indirect+zone valves

@ June 9, 2010 3:26 PM in Primary/Secondary & outdoor reset ,indirect+zone valves

If  you had a primary / secondary piping
loop on a cast iron  type FHW boiler
with a primary loop pump and the supplied Honeywell aquastat relay, a
indirect water heater teed off the primary loop(parallel) with it own
pump and the supplied
aquastat controler/ thermostat ,  4  Taco zone valves on the secondary loop
with it's
own pump and  a
Weil Mclain WM-ODR .  How would you wire in the the FHW boiler system
pump to run all the time during any type of call for heat but cycle the
burner on and off with the ODR , plus  wire in the indirect water
heater pump and aquastat along with the pump for all the space heating?

I use a Bacharach PCA 25 and like it very much.

Redesigning Heat & Hot Water Piping

@ June 22, 2009 8:35 AM in Redesigning / Heat & Hot Water Piping

Years ago with advice from another person, during a renovation project I moved my boiler to a cheap unused spot in my home, which happens to be down the hall from my bedroom. The existing system is noisy and most of all it short cycles. I now want to pipe it correctly. At the time I piped my Utica DV 100 boiler & Zone One indirect water heater and a 007 through a 1” x 1” x ¾” black pipe manifold. I installed a reducer ¾” x 11/4” for an 11/4” Taco zone valve and back down to ¾” copper back to the indirect. I have three baseboard zones all controlled with a 4-zone controller with priority all with ¾” zones .The longest total loop is about 145 ft. long with about 85 ft. of standard ¾” baseboard. At some time in the future will split that long loop but for now it will have to stay. (I am on a slab and must go under a doorway) the other zone has 20 ft of baseboard and the last zone has 40 ft. of ½” baseboard. I did add a Weil McLain wm-odr outdoor reset control, which helped the short cycling a bit. I am now ready to redesign the system with primary / secondary piping. I picked up the books Pumping Away, Primary Secondary Pumping Made Easy , & Hydronic Radiant Heating , but got lost about 2/3’s the way through the Primary Secondary . I have attached three drawing to this post, one that is of the existing system, one that has the indirect off the primary and one that has the indirect off a secondary. It would be great to have it reviewed by a professional to let me know what is the best way to go under my circumstance, in addition, what changes I need to make. (Missed valves ECT.) I also am wondering what is the best way to control this setup. Please note: My boiler room is on the second floor and very small (8’ x 6’) with a ceiling height sloping 4’ to 7’.
