Gas Hot Water Supply Heaters
Available in Indoor and Outdoor Models
 136,000 thru 1,826,000 BTU/Hr.

Rheem-Ruud hot water supply heaters are designed to provide hot water service to a variety of commercial applications
when used in conjunction with an appropriately sized storage
tank. These models are particularly suited for applications that
require high inputs and large volumes of stored hot water.

Construction Features:
• Reliable heat exchanger
Design – The all copper
heat exchanger is a single
bank, straight-through
design with a floating
return header immune to
thermal shock.

• Energy saving pump
control – The energy
saving pump control is an
electric device that allows
the operator to set the
desired time for the pump
to run after the water
heater shuts off. With the
energy saving pump control the water heater pump
is programmed to continue running for an optimum
period of time in order to
absorb the residual heat
from the combustion
chamber and use it in the
system.

• Compact design –
The low water heater
mass design offers
substantial savings in
weight and cube over
most cast iron, steel tube
and storage-type water
heaters making it ideal
for rooftop installations
and in tight quarters.
• Minimal heat loss design
– Spark-to-pilot (IID)
system is standard on
all models.
• Glasslined cast iron
headers –
To handle aggressive
water conditions. (Models
GBBP/GBB136 feature
bronze headers.)

Certifications and Ratings:
• Efficiency – These models have been tested according to ANSI
test procedures, and meet or exceed the 80% thermal efficiency
requirement of current ASHRAE standards (Part of the Federally
mandated Energy Policy Act (EPact)). Also exceeds energy
efficiency codes of all states.
• Safety and Construction – These products are design certified
by the CSA: a) As a Hot Water Supply Water Heater equipped
with on/off controls for use in conjunction with a storage tank. b)
For operation at 180°F. c) To meet all safety and construction
requirements of ANSI Z21.10.3.c) For installation on combustible
flooring when used with a combustible floor base, and, or e) for
alcove installation. ASME construction is standard on all models.
Certified for a 160 PSI Maximum Working Pressure.

Three Important Reasons to Choose Hot Water Supply Heaters
from Rheem-Ruud Commercial Water Heaters
Reliability
• Like all of our water heating products,
Rheem-Ruud hot water supply
heaters are crafted to exacting standards. Each detail of design, engineering and construction must meet
our criteria for performance and durability.
• The heat exchanger (1), for example,
is constructed of 100% copper. High
Velocity hydraulics (2) virtually eliminates problems of scaling and corrosion within its waterways. The cast
iron headers (3) are glass-lined to
assure that the entire heat exchanger
assembly is resistant to corrosion.
• Every Rheem-Ruud hot water supply
heater features titanium stainless
steel burners (4). They operate quietly, will not clog or corrode, and have
far greater temperature resistance
than cast iron. The controls (5) are
factory adjusted and completely
enclosed for reliable, automatic
operation.
• The outer jacket (6) is galvanized
and enamel baked for lasting
aesthetics.

• Today’s demands for volume hot water
must be met economically, so we’ve
attempted to use every fuel saving
technique conceivable. The resulting
82% efficiency will save you money in
fuel costs for years to come.
• The integral finned copper tubing
(7) in the heat exchanger provides
nine times more heat transfer area
than smooth tubing. Efficiency is
boosted even further by V-baffles (8),
which redirect the heat across the
finned tubing. The insulated combustion chamber (9) features corner
sealed and interlocking refractory
panels to minimize chamber radiation
losses.
• Economy is further enhanced with a
special energy saving pump control.
This automatic control continues to
pump operation until all usable heat
has been absorbed from the combustion chamber and stored in the tank.
• Access to water heater for inspection
is simple. All Rheem-Ruud hot water
supply heaters feature a heat
exchanger inspection panel (10)
and a removable door to access the
slide out burner drawer (11).

Flexibility
• You’ll find that Rheem-Ruud hot
water supply heaters are perfectly
suited for many commercial, industrial and special application needs
requiring economical, reliable supplies of hot water. The optional factory supplied pump is designed to
handle nearly all water conditions
• Our standard sized water heaters –
nine models ranging from 136,000 to
825,000 BTU – are designed for hot
water supply in commercial applications. Each model is available for
indoor and outdoor installation. The
outdoor models feature a special
draft system which is wind, rain and
debris-proof.

• Our large sized water heaters –
seven indoor and seven outdoor
models ranging from 926,000 to
1,825,600 BTU – meet the heavier
demand of larger multi-family housing and commercial applications.
They are ideal for use as summer
replacement water heaters, eliminating the need to fire large central
heating water heaters merely to supply domestic hot water.
• All of these Rheem-Ruud hot water
supply heaters are compact and
convenient; they save space, fuel
and installation cost.

NOTE: Additional pipe fittings will increase the system head loss. Select a pump based on the water hardness, flow and system head loss. If water heater is
more than two stories above the tank, consult the pump manufacturer.

Sizing based on water heater and tank being placed 5 feet apart. The
equivalent length of pipe valves and fittings in the system is as follows.
1-1/4" NPT = 65 Ft (136)
1-1/2" NPT = 70 Ft (186-399)

Recommended Specifications:
Hot Water Supply Heater(s) shall be model ________________, manufactured by RHEEM-RUUD,
having gas input of __________ Btu/hr. and recovery rate of _____________ GPH at a 100°F temperature rise when tested and certified at ____________ thermal efficiency. Water heaters(s) shall have the
CSA seal of certification and supplied with a factory installed 125 PSIG ASME pressure relief valve.
Water heater(s) shall meet or exceed the thermal efficiency requirements of ASHRAE. Water heater(s)
shall be ASME inspected and stamped for 160 PSI working pressure complete with manufacturer’s data
report. Water tube heat exchanger shall be constructed of straight integral copper fin tubes with fins
spaced at seven fins per inch. Tube sheets shall be ASME fire box steel. Headers shall be of glasslined
cast iron and joined to the copper tubes and tube sheets by means of silicone “O” rings to form a positive seal between the copper tubes and the headers to 1200 PSI hydrostatic pressure. Headers shall be
secured to the tube sheets by properly spaced bolts and flange nuts. Heat exchanger shall be readily
cleanable from either the right or left sides (or rear) of the water heater by removing header(s), and on
the right side, cleanable without removing external piping. Heat exchanger to be explosion proof on the
water side. Waterways to be 100% copper and glasslined cast iron to prevent galvanic action within the
water heater by positively sealing off water contact between ferrous and non-ferrous metals. Pump, flow
switch, and energy saving pump control are to be factory supplied and units over 400,000 Btu/Hr. must
have electronic intermittent pilot ignition.
Water heater to be equipped with remote bulb electric high limit control adjustable to 200°F. Main
electric gas valve to be 24 volt with 110/24 volt transformer. Gas pressure regulator to be factory set
at 4" W.C. Flame supervision shall be either 60 second thermopilot or 1-4 second electronic shut down.
Burners to be raised port and die formed from stainless steel alloy, mounted on a removable drawer,
capable of quiet ignition and extinction, and equipped with fixed primary air ports.
Models above 330,000 Btu/Hr. shall be CSA design certified for a minimum efficiency of 82% on indoor
and outdoor models.

Limited Warranty
All GB models feature a five year limited warranty on the
copper heat exchanger and glasslined cast iron header.
Please refer to Commercial Warranty Information brochure
for complete limited warranty information.
