Features and Benefits

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.
