Guaranteed effi ciency and easy 
maintenance assure low cost operation
All Bryan RV Series boilers offer these operating and  performance features
Guaranteed effi ciency
The breakthrough in water tube boiler design that pro-
duced the RV Series provides operating effi ciency  so 
reliable, we guarantee it to be 84% for hot water boilers 
and 82% - 15 psi / 80% - 150 psi or better for steam boilers.
The Bryan Flexible Tube
Bryan’s exclusive “Flexible Tube” design 
eliminates the possibility of damage 
from so-called “thermal 
shock.” Tubes are easily 
removable and replaceable, 
without welding or rolling, 
eliminating long, expensive 
downtime should repairs 
ever be required.
Water cooled furnace
The configuration of the 
water tubes provides a 
water cooled combustion 
chamber. A high percentage 
of the heating surface is exposed to direct radiant heat, 
increasing water velocities and heat transfer.
Large steam drum
The steam drum has generous water volume and steam 
release area. This design, along with effective drum 
internal functions, results in a stable water level and 
produces extremely dry steam at all load conditions.
Accessibility of furnace and tube area
Inner panel provides easy and complete access to furnace 
and boiler tube area, as well as to burner head. All panels 
are heavily insulated and sealed to boiler frame. All access 
is from only one side.
Compact design, minimum fl oor space
With our compact water tube design, the overall size of the 
unit is less than most other types of boilers, yet maintains 
a full fi ve square feet of heating surface area per HP. 
Water Boiler
Combination thermometer and altitude 
gauge, ASME Code rated boiler relief 
valve, water temperature control (240°F 
max std.), high limit control, probe 
LWCO.
Steam Boiler
Steam pressure gauge, steam pres-
sure control, combination low water 
cutoff and pump control, auxiliary low 
water cutoff, high limit pressure 
control, ASME-rated safety valve, 
water glass set.
Straight gas fi red unit
Electronic combustion safety control, 
automatic operating gas valve, safety 
gas valve, pilot solenoid valve, pilot 
ignition assembly, main manual gas 
shut-off valve, pilot cock, pilot and 
main gas pressure regulators, air safety 
Needing only 32" for tube removal, and on only one side 
of the boiler, the RV Series boiler occupies very little space 
in the boiler room. This can result in considerable savings 
in building costs. Pressurized fi ring permits minimum 
sized breaching and vent.
Multi-pass fl ue gas travel
High velocity four-pass fl ue gas travel is obtained by a 
unique baffl ing system. This contributes to maximum fi re 
side heat transfer and overall high boiler effi ciencies.
Thermal blend water return
Bryan’s unique “thermal blend” return blends cold or 
cooler return water with warmer boiler water abridging it 
to design operating temperatures. An injector tube directs 
the “mixed” water fl ow through the downcomer to the 
lower header and heating surfaces at a temperature above 
possible condensing conditions. This reduces the possi-
bility of “cold spots” and 
damage from corrosive 
condensation.
Positive internal 
circulation
Each pass of the Bryan 
water tube slopes up-
ward. This confi guration, 
along with the large vol-
ume down-comer water 
legs, provides the extremely 
rapid natural thermal inter-
nal circulation, promoting 
both high effi ciency of heat 
transfer and uniform temperature 
throughout the boiler. Eliminating stress 
damage caused by unequal temperature distribution is 
especially important for heating systems, particularly 
where intermittent or continuous low temperature water 
returns may be encountered.
