Notice how AHS sales is noticeably absent from the forum after I put them on the spot about how tall a S130 with the new hopper was. That was a question you answered by measuring your new boiler. Why isn't the overall unit height on AHS's spec sheet?
Good point, this thread is in the AHS forum already, so they must be monitoring it. Some direct feedback from the manufacturer would be great.
In the "Troubleshooting" section of the manual, problem #9 is titled: "Coal Gas Ignitions (evidenced by an audible bang) during the off cycle", and the only answer to the problem is "Poor Draft", followed by this advice: "Assure .04" of water with a manometer. Increase flue height if necessary, or use an auxiliary power vent."
In the manual proper there is mention of allowing firing upon first start-up to continue for 2 to 3 hours before turning on the grate switch. It also mentions that during the off-cycle the sight hole cover must gap open 3/8" or more (though the reason given for this is to prevent over heating the unit during the off-cycle, with no mention of puff-backs). That's it.
Off topic, but in the five page "Installation Check List" flier I did see where there is an "oil auto switch over option" available. Great place for this to be mentioned. You have to already own the boiler in order to get the manual and this additional check list. Once you own the boiler it is too late to get this option. And there is no mention if this option is for an oil burner unit that is integral to the Coal Gun, or if it merely auto switches on your existing and separate oil boiler.
