The gist: epa clean burn regulations of the late 80's then 90's. The stoves are beautiful, but beauty comes with cost, like cast molds and imports, its hard to re-tool or make new molds based on burn tech for small / medium companies, so they opted to keep the old time & true design and just reshape the guts of the stove to meet clean burn regs, eventually the original company was bought and sold a few times, all new buyers have tried to keep the stove aesthetic vibe, the damage was done and in 2019 VC was bought by another larger company, this company has turned up the notches with new stoves for 2020, some aesthetics original to the company, but between harder to achieve 2020 regs and the black eye damage of the last 25-30 years with failed down draft systems, a deep hole was made and its hard to climb out of it.
I'm def not saying clean burn is bad, it just didnt work out for this company's business model

Im going to rant a bit here
VC gamed the system like any company does to get to a certain arbitrary number. It would be very hard to achieve what they say is possible IMO.
Many will say ah, you just need the cat to get those numbers.
Welllll....?
From the VC dauntless book and filled under EPA reports 240-19 (without catalyst) 246-19 (catalytic)
EPA Certified Emissions:
1.1 g/hr (
without catalyst) 1.2 g/hr (catalytic)
Well how could that be?
Well the cat helps you control it better at least.
Welllll,... if by control you mean your ability to have a larger difference in low BTU potential and high BTU potential (which you want to see in any stove),
12,250 - 49,430 (without catalyst) 14,520 - 41,940 (catalytic)
Wait....so WITHOUT the cat...you can go lower AND higher?
Well how could that be?
Two balls of stainless brillo pad shoved into the cat cavity has the same effect as having a cat in for controllability. Not that you want to ride with 2 brillo balls in your cat cavity unless you like voiding your warranty.
SO what is the REAL world experience with a VC stove. Many people like me will find that there is a very fine teetering area you want to be on the air control based on a number of factors and experiences. This is not an appliance. There is no on/off switch. There is way too low, way too low, way too low, way too low, too low, too low, .....ok nice....,too high, too high, way too high, OMG WHATS HAPPENING HIGH.
Marketing people are geniuses in coming up with ways that dont exactly indemnify themselves, but do create an argument FOR the company. Here's a great example. VC knows their stoves are challenging to operate, and that their entire business is surrounded by the top hatch door. I was sucked into it. I could put a cage around my stove for kids/pets and still be able to load it quickly. As if you can just toss a log or two into a VC stove and go about your business. That's laughable.
From the VC owners manual:
Conclusion: Wood-burning is an art rather than a science. Once the stove and chimney system are in place, you can only vary your technique, mostly your timing, to achieve good results.If you keep track of your burning habits and relate them to their effects on the stove’s operation, you’ll be rewarded with good performance and years of reliable heating.
So, what should we garner from that? 1. you will be constantly babysitting your stove until you figure out some very unforgiving parameters that you must abide by, and even a slight variation sends you into the TOO category (TOO low or TOO high). 2. If you do not track your burning habits YOU WILL BE PUNISHED! Fear the wrath of not abiding by the art!
But wait a minute you say, let's unpack that 'conclusion' by VC a bit more shall we?

Wood burning is an art rather than a science. Not, wood burning is more of an art than it is a science, but it is an art - and not a science. Wow. At first read you think that is a rather benign statement. But think about that, they are basically saying - there is no right or wrong way to run the stove after all, it's art and subjective to the viewer of what is right or wrong.. Well that's telling.
Or how about, the fact that they say It's an art, not a science BUT then go on immediately afterwards to suggest you should track your burning habits and relate them to the effects on the stove's operation. Um, forgive me if I'm wrong but isnt that called "cause and effect" <----- the very foundation of science and engineering (next to math which is the nucleus of everything).
So which is it VC, Science? Art? Mana? A new type of divining rod? A portal to hell maybe?
yet, in the end - once I have my stove cruising, I feel a sense of satisfaction. Like getting a bolt unstuck that you've been working on for 2 days, or looking down at the scale and noticing progress after 2 painful weeks of cutting out everything that is bad for you but tastes so great.
