Features and Benefits N/A Ventmaster™ power direct vent commercial water heaters provide outside air for combustion, which eliminates negative air pressure issues in tight construction. Models are available in 199,900 and 250,000 BTU/hr, with a maximum temperature setting of 180 degrees Fahrenheit.

Thermal Efficiency
Meets or exceeds a minimum of 80% non-condensing).

System Sentinel™ LED Diagnostic System
Our exclusive diagnostic system, with glowing LED lights, verifies system operation sequence by sequence.

Patented Technology
Patented multi-flue tank design has a proprietary steel formulation with two coats of high temperature porcelain enamel to maximize corrosion resistance. This results in a superior, long lasting heat exchanger.

Integral Automatic Blower
The 120 Volt blower assists in quietly discharging combustion gases.

Gas Control System
The control system has a fully adjustable thermostat from 100º F to 180 ºF. The 24 volt combination gas valve includes main gas pressure regulation and an on-off manual valve. The 120/24 volt transformer and high limit cut-out allow for accurate and safe temperature settings.

Easier, Less Costly Venting
Installs with 3" or 4" Schedule 40 PVC pipe; no masonry or metal vent chimney is required. Can be installed virtually anywhere. Maximum vent length is 50 feet.

Base Rail Design
Provides better handling when moving the unit.

Full-port, Full-flow Drain Valve
Factory installed brass drain valve allows for faster draining and servicing.

Direct Spark-to-Pilot Ignition System
Less fuel consumption.

Hand-hole Cleanout
Easy removal of sediment deposits.
Testing and Certifications N/A Altitude Certification
Standard models certified up to 2,000 feet; high altitude models available up to 8,000 feet

CSA/ASME Rated T&P Valve
Factory installed relief valve
Warranty N/A
  • 3-Year limited Tank Warranty, Upgradeable to 5-Year Warranty.
General Information N/A Efficiency
All models tested according to ANSI test procedures, and meet or exceed the thermal efficiency and standby loss requirements of ASHRAE standard (EPact). Also exceeds energy efficiency codes of all states including California Energy Commission (CEC).

Safety and Construction
Design certified by CSA®: For operation at 180 degrees; meets all safety and construction requirement of ANSI Z21.10.3; as an automatic storage or instantaneous water heater; as an automatic circulating tank water heater; and for operation on combustible floors and in alcove installations. All models are North Carolina Code compliant.
Certified for 150 PSI maximum working pressure (160 PSI for ASME models).

Optional ASME Construction
ASME construction is available on designated models.
Note N/A Not available in Canada.
