VentMaster Power Direct Vent Gas Commercial Water Heaters
Available in 100 Gallon Tank-Type Models

150,000 BTU/Hr. Thru 250,000 BTU/Hr.
VentMaster power direct vent gas commercial water heaters by Rheem-Ruud
are designed to fill the need wherever large quantities of hot water are
required. Typical installations include restaurants, hotels, laundromats and
multiple family housing.
Construction Features:
• Non-condensing design –
helps prevent corrosion –
no condensate pump or drain
needed.
• Integral automatic blower –
with 110/120 volt electrical
system.
• Patented multi-flue tank design –
proprietary steel formulation,
patented multi-flue design, and
two coats of high temperature
porcelain enamel to maximize
corrosion resistance result in a
superior heat exchanger design.
• Spark-To-Pilot ignition system –
standard on both models.
Provides reliable and energy sav-
ing ignition sequencing by igniting
the pilot only when the thermostat
calls for heat.
• Base rail design –
for better handling when moving
and positioning the unit.
• System Sentinel™LED
diagnostic system –
our exclusive diagnostic system,
with glowing LED lights, verifies
system operation sequence by
sequence.
• Full port, full flow brass drain
valve
• Temperature and pressure
relief valve –
AGA/ASME rated and factory
installed.
• Hand-hole cleanout –
for removal of lime/sediment
deposits.
• Gas control system –
fully adjustable thermostat from
100° F to 180° F, 24 volt
combination gas valve includes
main gas pressure regulation,
on-off manual valve, 120/24 volt
transformer, and high limit
temperature cut-out.
