Rudd G100-200A Installation Manual
Universal Gas Commercial Water Heaters
Available in Sizes Ranging From 35 - 100 Gallon Tank-Type Models
98,000 BTU/Hr. thru 400,000 BTU/Hr.
Universal 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:
Small Jacket
Diameters
Short
Floor-to-Vent
Heights
Multiple
Water Connection
Options
• 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 overall 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
Certifications and Ratings:
• Efficiency – these models have been tested according to ANSI test
procedures, and meet or exceed the thermal efficiency and standby loss
requirements of current ASHRAE standard (Part of the Federally
mandated Energy Policy Act (EPact)). Also exceeds energy efficiency
codes of all states including California Energy Commission (CEC).
(On Selected
Models)
(With Optional
Leg Kit)
• 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 instantaneous 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. UL Sanitation (NSF5) compliant models are available when
equipped with optional leg kit. (Part No. AE35450)
