Where to download

  • bosch-homecomfort.com — search by model number; download Installation & Operation Manual plus Owner Manual
  • Bosch customer service — 1-866-642-3198 will email any manual within 1-2 hours
  • Hydronic Piping Guide — separate document for Greenstar combi installs

Documents by line

  • Greentherm — separate manuals for 9999 SE, 9900 SE, 9000, 5300, 7.2. Each manual is model-specific
  • Greenstar combi — model-specific manual (Greenstar 100, 131, 151) PLUS the Hydronic Piping Guide. Both required for warranty-compliant install
  • Tronic POU mini-tank — single user manual covers most Tronic 3000/6000/7000 series
  • Tronic Heat 3000 — single installation manual; emphasizes electrical service sizing

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.
