Installing windows with no nailing flange
I am in the process of having 20 Loewen(Loewen // Design. Create. Inspire.) all wood casement windows installed in our 23 year old brick veneer house. Its a brick to brick installation. The windows came with brick mold attached however, they don't have any nailing flange. The installation instruction available from Loewen talks about windows with nailing flange.
So how does one install a wood window without nailing flange? Just nail the jambs to the window frame? Or does one need to attach snap-on nailing fins first? The windows are painted outside, however, I plan to stain inside. Jambs are made of Douglas fir with vertical grain, they look beautiful. So, if the windows are nailed from the jamb side I am worried that the nail heads may spoil the final stain finish. Is this a valid concern? See I am not doing the installation myself, I just want to understand the process. These windows are expensive and I want to be sure that they are installed right. Any help will be much appreciated.

Assuming the windows are measured correctly??...Do those measurements equate to the brick outside around the windows.There should be an allowance of about an 1/8 of an inch around.
Plus are those existing brick openings nicely plumb & level?
If so,the unit should virtually sit self supported within that opening.Shims may be needed to adjust for proper plum & level.
A good quality foam (ENERFOAM is what I use) will stabilze the unit from inside,almost without the use of screws or nails BUT if you have a decent installer,he will be able to disguise his screwholes with plugs.

Loewen window installation
The windows you ordered have brickmould which means they wouldn't have a nailing flange to install the window. You will probably want to use masonry clips (available from the dealer). They should have been requested at the time of your order, or at least recommended by the dealer. Follow this link from Loewen's website to see an illustration of the masonry clips and how they are installed - http://architect.loewen.com/architec...cellaneous.pdf
I work in the Loewen Architectural Services department for Loewen, so if you need anything else feel free to call. 1-877-563-9368.

Thank you all for your suggestions and inputs. I am finally getting the idea!
Total jamb depth of these windows is 7 and a quarter inch. So, there's enough room to follow mikehammer's suggestions. However, at the end I like what the Loewen expert says.
To Loewen help: As a customer of your company's product I appreciate very much of you taking time in answering my question. This is what I call customer service! Yours seems like a preferred method of installing these windows. Though I have engaged a general contractor (GC) to do the ordering and installing of the windows, I talked to a rep from Toronto Loewen center several times when he came by my house to take the measurements. I wonder why he didn't suggest masonry clips. He knew what my intentions were (paint outside and stain or clear finish inside). I will throw that question to him and my GC. I waited nine weeks to get these windows and I am willing to wait an extra week if that's what it takes to get the masonry clips for proper installation.

An Update: The installer finished installing the windows about a week ago. At the end he went with what mikehammer suggested, that is he used countersunk screws to attach the window to the frame through the jamb. With Dogulas Fir trim around the window, they look awsome, with enough wow factor to get high praises from the neighbors. The windows look so beautiful in their natural colors that I decided against applying any stain and instead going to put a couple of coats of water based clear finish (Varathane). I hope its a good choice!
