the Taco controller should work fine.
You would need to check with your local codes and requirements, this based on your location and the installation.
This appliance must be vented into a listed gas vent, masonry, metal, or factory- built chimney as required for Category I appliances.
Burnham does require chimney liners with this boiler. See page 8 of the Installation Guide at the link below for more information. The boiler comes standard with a Taco 007 circulator pump. The IQ Control System provides extra options (a touch screen display, as well as outdoor reset, low water cut-off, and high limit plug-in cards), but you do not have to use any of these features. http://s3.pexsupply.com/manuals/1253196590775/17461_PROD_FILE.pdf
I'm fairly certain that the boiler need a liner, check w/ local plumbing code official. Yes it comes w/ a pump. No, not hard to install.
Based on BTU ratings, the closes unit is the ES2-6. This will have to be inspected further by a technician or installer.
I have installed two of these boilers and have had no problems. Thank You Stan Miller
low water cut off was dead on arrival, replaced and never a problem since
This particular boiler is actually designed to vent through a 6" chimney, so no modifications will be necessary.
No, you cannot do side-wall venting with this unit.
Yes, the ES2 boiler is only available with electronic ignition (not standing pilot).
This unit does come with an electronic ignition.
If there is not enough make up air you may need a fan-in-a-can unit.
