Thanks for the advice.
I will play it by ear. I've run it for a couple months in 100+ weather with no overheating but things change sometimes. One thing with the 265 there is no place on the head to hook up a bypass line and with the zips riser you have to make some provsion for that. I had a t-stat in it that I drilled three small holes in but it stuck so I took it out and didn't replace it.
