Nope. Those things draw something like .7 amps at idle and 1.3 amps when running. I normally just jump off whatever 15 or 20 amp circuit is nearby that legally has an amp to spare.
Check your instruction booklet. Most of them that I've installed have a GFCI protection requirement.
Had an inspector say they required a dedicated circuit home owner wanted it dedicated so I didn't argue .I know somewhere in the book theres something about the boiler being dedicated but cant seem to find the article thought it might apply.
