Utica boiler clicking

I have a Utica propane boiler Model # M75AGB that has been clicking when getting ignited. Last night it wouldn't stop clicking. I've turned the boiler off and restarted it, but it still clicks. Both propane tanks read 30, which i think means 30% full so I think that's not the problem. The boiler is 27 years old and is used for both heating & hot water. Does it need a new igniter?

    First order of business

    is to call a pro. Fixing gas equipment is not a DIY job, especially with propane that can pool on the floor and be ignited, causing an explosion. Seriously. People have died this way.



    If that boiler has electric ignition, I suspect it's the old White-Rodgers setup due to its age. The successor to the AGB series, the MGB, originally came with this system when ordered with electric ignition. I seem to recall this system is no longer approved for propane (if it ever was), since it will try to light the pilot indefinitely rather than locking out as newer systems do.



    If I'm right, you'd need to upgrade the ignition system and main gas valve. Honeywell still makes a kit for this that is approved for use with propane. At any rate, parts for the White-Rodgers system are getting hard to find.

    Poof:

    And if you've never experienced the floor going "POOF", it is something that you will definitely want to pass on. Especially if it is in a confined space.

    If the rating plate doesn't say LP Gas but Natural Gas, and it doesn't have signed conversion stickers on it, it may be an illegal conversion. The appliance may not be listed for LPG.

    Call a qualified Gas Pro.

    That boiler

    probably has an old White-Rodgers Cycle Pilot System. Many of those have been replaced by the boiler manufacturer with a retrofit kit. Weil-McLain had theirs changed over to a hot surface igniter.



    I would have the professional you hire check with Utica or he can give me a call at 401-437-0557 and I can recommend a retrofit as soon as we know what you have for a system.



    It would help if you took a picture of the boiler controls and gas valve and give us some numbers so we can help you and your contractor.
