Low Water Cut-off placement

Hydronicolic

On an 11,000 sf truck garage, we are using a WBN285 wall-hung boiler. As it works out, the boiler is sitting higher than all other piping. Is it possible to install a tee, on top of the boiler, at the pressure relief valve and install it there with the lwco in the side and the relief valve in the top? Or do I have to swing some copper up higher than the boiler and then back down. The Crown wall-hung in my house has the nifty criss-cross fitting with the relief valve, lwco and supply all happening there at top, thus posing the question at hand. I'm thinking maybe it could create some nuisense call backs and also wondering if it is legal.
