Residential/Light Commercial Gas Tankless Water Heaters

TANKLESS RESIDENTIAL/LIGHT COMMERCIAL MODELS

Fully modulating, gas fired, tankless water heater specifically designed for residential and light commercial applications. Capable of supplying hot water for domestic hot water systems or combination heating and domestic heating applications (local codes dictate proper compliance). Features HRS35 copper alloy and a thicker heat exchanger drum for added durability. Up to four units can be easily linked, using the Easy-Link system, without a multi-unit controller in systems for larger applications.

Specification

Water heater(s) shall be Model _________________ as manufactured by A. O. Smith. The water heater(s) shall be a copper coil integral fin and tube construction with quick release brass or bronze waterways. Heater(s) will be factory assembled and tested. The heater shall be vented with 4” Stainless steel Category III vent pipe a distance not to exceed 50’ (equivalent) feet terminating vertically or horizontally as prescribed. Intake air with optional direct vent kit may be of such material as ULC s636 PVC or CPVC, galvanized B-Vent, corrugated aluminum or stainless steel or Category IV stainless steel not to exceed a total of 50’ (equivalent). The heater(s) shall be controlled by onboard solid state printed circuit board monitoring incoming and outgoing temperatures with factory-installed thermistors, sensing and controlling flow rate to set point temperature with control both air and gas mixture inputs to maintain thermal combustion efficiency. Unit also consists of, inline fusing, spark ignition and sensor system, aluminized stainless steel burners, air-fuel ratio rod, Hi limit switch, modulating and proportional gas valves, freeze protection sensor and heating blocks and overheat cutoff fuses. The water heater(s) shall be CSA listed, exceeds the energy efficiency requirements of ASHRAE 90. 1b-1992.
