THE UNIVERSAL
BOILER
The Severn Boiler leads in appearance, design and advanced features. The skill of capable engineers and industrial designers combined to produce it. The internal con struction is scientifically correct and properly balanced to assure more than average heating power, quick heat-making and low operating cost. Many refinements and improvements are included for extra convenience and laborsaving. A handsome jacket in the new Forge Red color just perfected by AmericanStandard, together with its streamlined doors, give the Severn its striking appearance.
The Severn is made for small to medium sized homes. It's a universal boiler, specially designed to burn the fuel used with high efficiency and economy. With all its quality features it is moderately priced, and merits the careful consideration of homeowners and builders who want to heat their homes more abundantly and with less operating cost.
NEW FORGE RED FINISH
The attractive jacket in the new Forge Red finish is both distinctive and durable. A warm shade of red, this new jacket finish has a smart hammered effect, and blends with almost any color scheme. The jacket surface is easy to keep clean and new-looking with a minimum of effort, yet it is hard and un usually resistant to scratches and marring.

MODERN REFINEMENTS
The Severn Boiler includes many improvement^^ for convenience and good appearance. For ex-V^ ample, the grate shaker is located on the left side of boiler, out of the way, and has a long detachable handle that eliminates stooping, makes shaking easy and quick. Water Column on steam boilers is located on the side, and the glass is easily visible through opening in jacket. A removable panel provides convenient access when necessary. Smooth fitting doors all have concealed hinges, which carry out the stream line effect. The door handles are ball shaped and air cooled, adding a unique touch to the whole ensemble. All doors are protected against warp-^ ing and damage by cast iron baffle linings. X

IMPROVED STYLING
The handsome jacket of the Severn was styled by industrial designers who have an intimate knowledge of home requirements. This fine boiler combines simple beauty and utmost utility. It will harmonize with practically any surroundings.
HEAVY INSULATION
The Severn has a thick layer of insulation be tween the jacket and the boiler. This effectively prevents heat loss and helps to save fuel.
BILTIN TACO WATER HEATER
When specified, hand fired steam and all stoker fired Severn Boilers can be equipped at small extra cost with a Biltin Taco Water Heater, which will supply abundant hot water for domestic use while the heating system is in operation. Oil boilers and oil heating units can also have similar heaters for supplying hot water the whole year 'round. These are described elsewhere.

AUTOMATIC FIRING
EXCELLENT FOR OIL OR STOKER AND READILY ADAPTABLE TO GAS
Because of special care and ingenuity in design ing, the Severn Boiler is also well adapted for automatic firing with oil, stoker or gas. Highly efficient performance with any good oil burner or stoker can be expected. Burners may be in stalled in front or rear, and, due to special open ings provided, stokers can operate from front or either side. The illustrations at left show the external appearance of Severn Oil and Stoker Boilers. Internally they follow the same general design as shown in the cutaway views. The Severn also offers the advantages of efficient automatic gas firing, with the Stanflame Con version Burner or other quality conversion burners.

SPECIAL COMBUSTION CHAMBER
Dependable, fuel-savtng perform57oA/r may be installed in
front or either side.
SEVERN STOKER BOILER
The Heat Lib-O-Rator Refractory Combustion Chamber, specially designed for the Severn Oil Boiler, is available at slight extra cost. This is a factory molded chamber which helps rapid and complete combustion and eliminates the labor and expense of building an ordinary hand-made brick chamber.
BILTIN TANK TYPE OR TANKLESS WATER HEATER
On Severn Boilers for automatic firing, a Biltin Taco Water Heater is available at small extra cost. The Tank Type Taco is connected to a storage tank, and the Tankless Taco (on oil-fired boilers and oil heating units) is self-contained and requires no storage tank. Both will supply ample hot water for domestic use, plus all year 'round hot water when oil fired.
PROVISION FOR ALL CONTROLS
All Severn Boilers for automatic firing have necessary tapping arrangements for connecting the conventional controls required. These vari ous tappings are shown under "Control Applica tions" on another page. This is a further step to simplify installation of these boilers.
SEVERN ARCOFLAME OIL HEATING UNIT
This is an efficient and fully coordinated BoilerBurner Unit consisting of the Severn Oil Boiler and flange-mounted Arcoflame Oil Burner. Both are specially designed to work as a team -- to give the best possible heating comfort and economy. In the Severn Oil Heating Unit the Heat Lib-O-Rator Refractory Combustion Chamber is regular equipment.
