Bottom line
Always work from the model-specific Installation Manual. For Greenstar combi, the Hydronic Piping Guide is mandatory reference — generic hydronic guidance isn't a substitute. For Tronic Heat electric tankless, the electrical service sizing tables in the manual are critical — undersized service is the #1 install mistake.
