wow all i can say is that an OAK made a big difference in our stove. last year we ran it without the OAK and it burned nice. this year i added a custom OAK kit since it is an European stove, Ecoteck,. i went with inch and a half copper tubing. what a difference. the glass has been clean for 3 days even when running at power setting 1 at night. normally in a day the glass would be foggy and by day 3 it would be hard to see the flame, now its nearly crystal clear 3 days since last cleaning.
just had to tell all.

just need to make a guard/cover to go over the inlet. thinking 1/4 inch wire screen bent in a box shape.
 
Is 1 1/2" tubing adequate for that stove? Seems small.
 
the inlet pipe at the back of the stove is just shy of 1.25 inch so i figured 1.5 was a good idea.
 
to early to tell, plus it warmed up.

If the tube is short the 1.5" should be fine. If it is long you would be better off with a larger diameter. I have a six foot long OAK on my PDVC so I went with 4" corrugated aluminum vent material.
 
it is only a short (6 inches) then an elbow straight down then a 5 foot piece of tubing. thats it.

That sounds like a very long skinny pipe. I think you would be better off with a larger diameter.
 
its larger then the existing inlet pipe already.

This is from my PDVC installation manual:

"Outside air is mandatory for this unit to operate properly. This unit has been designed and tested
with this connection, because so many homes are airtight and there is not adequate combustion air
available inside the dwelling. The air intake pipe is located on the bottom side of the burn pot (from
the rear) and measures 1 ½” inside diameter (I.D.). The connection can be made with a metal 1 7
/8 ”
I.D. coupler and pipe (see “Important Information” section of manual), and should exit through the
wall. Be sure to secure the pipe to the unit with a clamp or aluminum tape. The outside end of the
pipe should be covered (screened) to prevent foreign matter from entering the system. Our Outside
Air Kit (Part Number PU-OAK) can be used. If the unit is located below ground level, you will need to
run the pipe up and then outside the dwelling. NOTE: If the total run of the connection exceeds 6’, if
more than 2 elbows are used, or if a basement installation, use 3” metal pipe (and coupler) instead"

It is a good guide for what you are doing.

sounds good but my inlet is 1.25 inch so i went the next quarter inch up instead of 1/8 inch plus its only a 5 ft run with one 90elbow.
