Appliance Location
1. Boiler Location – Locate the indirect-fired water heater as
close to the boiler as practical.
2. Fixture Locations – For fastest delivery of hot water, place the
indirect-fired water heater close to points of use.
Additional Recommended Components
1. Shut-off Valves – Allows isolation of water heater from
domestic water system and/or boiler system during service.
2. Unions – Allows water heater movement during service if
adequate clearance cannot be provided.
3. Thermal Expansion Tank – If the water heater is installed in
a closed water supply system, such as one having a back-flow
preventer in the cold water line, provide thermal expansion
control. Contact the water supplier or local plumbing inspector
for additional information.
Do not plug the inlet and outlet tappings of tankless heater left
