Congrats on your new purchase!
Installation
It should be installed sticking out on your hearth as far as possible, the manual says it can be sticking out 5" or flush but every inch it's pushed in causes your heat to come out that many inches behind the surround.
When it's being installed ask the door to be swapped to the other side. Most people are right handed and store their wood to the right of the stove/insert. The doors on units generally open the wrong way by default. It's much easier during installation than after. There are 2 phillips screws, each on the back top corners of the facade. Loosen them, they hold two small metal pieces. Rotate the metal pieces, lift the facade up a little, and pull it off. Now you can swap door.
If you have the room, surround your fireplace walls with a layer of mineral wool insulation. You can fasten it with fender washes & tapcons to the current brick & mortar.
Features
The "cooking surface" is more a warming surface. It's insulated having a dead air space below it. You can't use it to judge temperatures using a thermometer, and it doesn't get hot enough to cook. A half kettle will be particularly ineffective on it.
Running
The air channels on the Clydesdale run underneath, go up the sides, over the top, and out the front. No back, the warmer you keep the sides the more heat you'll transfer into the living area.
Load the wood side/side. I tried front/back once and it burned great but covered the glass in crap.
Cold starts with soapstone is not particularly fun, I don't find them anyway. Put a piece of kindling on the top of your wood near the secondary burn tubes, that will help your secondary burn and be patient on when to cut back the air. Soapstone takes a while for things to warm and get moving. It's not uncommon to have a blazing fire, shut the door or turn the air down and have the fire go out. Have patience, from a cold start I keep the door open until the fire is blazing (about 5 minutes) and flames reaching the secondary burn. I shut the door, and give the fire 5-20 minutes on max air. I turn down the air slightly and wait another 5-10 minutes I turn down the air a little more. Particularly from a cold start, you can't go from max to a low or the fire will go out. What difficulty soapstone has going from a cold start, it makes up for on reloads. Get yourself some long fire resistant leather gloves, when you see there's some embers and time to reload, it's deceiving with soapstone because the inside can still be hotter than hell. Without gloves you can feel like your skin is about to blister trying to reload em. Also, and it's happened to me logs can spontaneously combust on reload. I put in 2 log splits, reach and grab 2 more and as I'm placing them the first two burst into flames and in a second the flames reach up and around the secondary burn baffle scorching my hand & arm in the process. Scares the #!*@ out of my wife and I. So, get those long leather fire resistant gloves and reloading them is a dream, they can get up to speed before you even shut the door.
If a piece of wood falls on the glass, leave it and clean the mess afterward. It's not glass it's ceramic and melts at a higher temp than the cast iron and stronger than glass, a log rolling won't break it. Unexperienced with the Clydesdale you'll frequently have a log roll into the glass. Out of the dozen times I attempted to push it away, about 8 times I either almost broke the glass trying, got hot coals in the way of me shutting the door, set the smoke alarms off, or nearly burned my floor. If a log rolls into the glass, leave it and clean the glass with Rutland brand Hearth & Grill Glass cleaner.
It's like Othello. A minute to learn, lifetime to master. There's a balance with your air setting. To much, and the heat leaves the firebox before having time to transfer. To low, you smolder and unburned fuel goes out the flue. Each wood type is different on the effect of the secondary burn. I burn almost strickly oak and learned to look for a specific "V" shape in the flames. That is, the lower part of the V has to be 4-6" wide directly coming off or between some logs. It hits the secondary burn turning the entire top into flame causing the "V" shape. If the lower part of the V is moving left & right, my air setting is too low I'm going to lose the flame & secondary burn shortly. If the lower part of the V is occasionally lifting up and off the wood and then settling back down onto it... my air setting is too low. If it's 8-10" wide, I have too much air. That's my trick, I'll have other flames occuring here & there in other places but the main flame needs to have that pattern. The lowest I can set my air is 25%, any lower my fire smoulders. So, the lowest air setting allowed on the Clydesdale may be too low in your situation to burn properly.
Warnings
See the air tubes on top? The roof above is insulation. Don't jab sticks or try to jam logs between the air tubes. It's solid, you can knock on it, but not very strong. Be certain to inform the sweeps (or be aware yourself) before they remove the baffle assembly up top that the ceiling above the air tubes is only insulation and they need to lift it up and out by the tubes or cast iron sides.
Tips
After your installers, pick up some furnace cement probably cost around $4. Remove the surround by lifting it up and pulling away. While your blowers are running feel around the insert on the sides & back for air leaks. The channels are mostly cast iron which can't seal tight. Plug the leaks with cement.
While the surround is off, notice the brackets that hold the surround on. They go inside the channels your heat comes out. There's about a 1" square space between the bracket and the inside of the heat channels, plug it with a little mineral wool so air comes out channels only.
