Low NOx Universal Gas Commercial Water Heaters
Available in Sizes Ranging From 35 - 100 Gallon Tank-Type Models
125,000 BTU/Hr. thru 400,000 BTU/Hr.
Universal Low NOx Gas Commercial Water Heaters are specifically
designed to minimize the difficulty of replacing failed water heaters and are
versatile for new installations. These products are designed for applications
requiring large quantities of hot water.
Construction Features:
• Universal tank design –
maximizes installation adaptability
by offering models with Top, Front
Side and Rear Side Inlet/Outlet
water connections.
• Universal space saver design –
short heights and small jacket
diameters result in greater
installation flexibility.
• 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.
• Low profile automatic flue
damper –
low profile design minimizes over-
all product height. New heavy duty
vent hood supports are designed
to withstand rigors of installation.
• Spark-To-Pilot ignition system –
standard on all models. Provides
reliable and energy saving ignition
sequencing by igniting the pilot
only when the thermostat calls for
heat.
• 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
• Low NOx Burner – The Power
Assist enclosed burner design
incorporates stainless steel multi-
port burner tubes for long term
Low NOx compliant performance.
A sight glass allows for burner
observation and the entire
assembly is easily removable.
A blower guard is provided
against post-installation damage.
The entire design is highly
resistant to the effects of negative
air pressures common to modern
commercial buildings.
Certifications and Ratings:
• Efficiency – these models have been tested according to ANSI test
procedures, and exceed the thermal efficiency and standby loss
requirements of ASHRAE (Part of the Federally mandated Energy Policy
Act (EPact)). Also exceeds energy efficiency codes of all states including
California Energy Commission (CEC).
• Safety and construction – these products are design certified by the
CSA: a) For operation at 180°F. b) To meet all safety and construction
requirements of ANSI Z21.10.3. c) As an automatic storage or instanta-
neous water heater. d) As an automatic circulating tank water heater.
e) For operation on combustible floors and in alcove installations.
All models are North Carolina Code compliant.
CERTIFIED FOR A 150 PSI MAXIMUM WORKING PRESSURE
(160 PSI FOR ASME MODELS).
• Optional constructions – ASME construction is available on designated
models.
