Constant problem that occurs on my new installation of burnham series 2 mod 203nil gei2 nat gas boiler with electronic ignition. I have 3 honeywellzone valves & honeywell electronic thermostats. System was installed by lic plumber, who has been trying to resolve over 6 follow up visits to date & claims to have contacted burnham engineering
- Boiler circ kicks on , auto damper opens ign sounds (slight buzzing noise) &burner ignites. During heating cycle a loud buzzing noise continues for about 1-2 minutes and stops & the repeats at various times during call for heat. The gas valve when you place hands on appears to be source of noise.Plumber is now checking on availability of flame sensor even though he electricaly cked & found nothing wrong with sensor or electric chek module(black box w/flashing codes that indicates a flame rod problem. (flame rod is from burnham manual designation under troubleshooting.
- Next the low water cutoff switch shows amber lite. Plumber changed wiring on switch around to bypass , . so I would have heat . He claims that LWC probe has flux or other debris on & will go away after about 2 weeks now that boiler is being used for heat every day/ I also hear a
ker-chunk sound when boiler shut s down. I am sticking with this plumber as I must & he must warrants his installation. I think he is making a good faith effort & shows up every time he is called. This plumber was/is on my gas suppliers list as recommended installer . On 11/12 he replaced pilot ignition, with no change problem buzzing problem noise remains. Plumber is now requesting Burnham field technician come with him on next visit.
Thanks in advance to anybody who can provide some ideas of what to check as to why a brand new boiler would have these problems. . I witnessed this boiler being received new from box Also should I request a new replacement of this boiler. Also am I damaging anything by running boiler ?
- Thanks :Utah
