Rheem Gas Hot Water Supply Heaters Water Heater User Manual


 
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 pro-
vide 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 con-
trol the water heater pump
is programmed to contin-
ue 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.)
