Re: Weil McLain CGA-4 Boiler Convert from NG to LP
While I do not recommend going against the manufacturer's recommendations, before going through all the trouble and expense, why not try with the existing ignition system? The worse that could happen is the module will shut down the system if there is no ignition. Now that I think about it, though I've never done it in the field, I'm pretty sure LP conversion kits are available for pretty much all systems and ignition systems that come setup for NG. I'm at a loss to figure out why Weil-McLain won't provide guidance. I still recommend calling a mechanical contractor. They should be able to provide you with more insight. |

Weil McLain does not approve of the conversion unless it is standing pilot. So basically, they will not even field the question and I had to do some dancing just to get an answer to anything. The guys voice was saying... you can do it, we just do not approve and are not liable.
All of the professional HVAC stores do not field questions from anyone but HVAC contractors. And I am not sure of a HVAC contractor that will do this if the mfg does not suggest it. I am looking online on the honeywell site (the mfg of the NG valve and spark ignition control module), and Honeywell has a conversion kit for the valve and they insist on changing the control module which I will do (I believe the control module may do something different with the speed of ignition or amount of gas for the pilot - hence, needs conversion). They also have a pilot orifice and main burner orifice conversion kit. So in my simple mind, everything is convertable.
And I plan on hooking this up myself and having a HVAC tune it before firing it up.
Any comments or reassurance is welcome. |
