Got it. The question is how the difference in 2" for clearances ? Jotul and most U.S. say 16". Maine and Canada spec 18". The Maine Fire Marshal's pdf. ( and Canada) give no reasonable explanation for the extra 2" . Is it a CYA ? Actual testing ? It's not unreasonable to ask how this was determined. For most of us with decades of wood heating, we do follow safety specs. This is the first time pushing an extra 2" front clearance.
You will need to talk to the fire Marshall as to how it is determined, I would not attempt to figure it out. They allow multiple vents into a single flue here but best you prove a few things first. And folks should know this a recipe for disaster.
If you didn't have me ignored or if you read the whole code you would know that requirement is for unlisted stoves. Yours is listed so it doesn't apply. You are fine with the 16"
16" is code, 18" is better....might as well go with 20"? Reminds me of a guy I used to work with. Someone asked what size boot he wore. "I'm a size 11 but I tried on size 12 and they felt so good I bought size 13."
No, they are minimum regulatory requirements, maybe affecting safety, maybe not. Sometimes they are worthy of ignoring.
As BHoller suggested, you're good. "Floors 1. Residential-type solid fuel–burning appliances that are tested and listed by a recognized testing laboratory for installation on floors constructed of combustible materials shall be placed on floors in accordance with the requirements of the listing and the conditions of approval."
Almost all effect safety in some way. But yes there are some whee the gain in safety may not be worth the effort. That is a decision people need to make for themselves after learning all of the factors involved.
So it is "allowed" for multiple vents into a single flue which CAN be unsafe we all know. Then they shove a 2" add-on to industry ( Jotul and others ) and U.S. SAFETY requirements. I rest my case your honor. Who are the experts ? And, when someone says "you're good" , question it. " You got to know what you don't know ", and some hang themselves as experts without portfolio in the real world. Ask. Confirm. Verify. ( Where the H did he get that ? )
Ok it is not me telling you it is ok. It is the code book if you read it it is all there in black and white. The passages allowing it were even pointed out to you. They didn't add 2"at all. And they only allow vents for solid fuel appliances to be combined on listed appliances which are listed to do so. Which means the manufacturer has tested it to confirm it is safe. Read the supplies codes. And yes I have lots of real world experience in this field.
I guess I made a "bad funny" if I have to explain it...no teams were actually joined/abandoned in the making of this thread...
No explaining necessary. Just kinda like Eric VW here..... when an opportunity exposes itself, take it!
The Hearth building lobby was able to bribe pay off more officials in Canada and Maine than the lower 49.
I know you are joking. But I just want to repeat there is no difference between Maine's hearth requirements and the rest of the US
