American Gas Association for use with natural or
propane gas. The type S boiler can be used in steam
systems with a maximum working pressure of 15 psig.
The type W boiler can be used in water systems with a
normal working pressure of 30 psig and is available
for systems with working pressures of 50 psig or 100
psig when appropriate gauge and relief controls are
used.
All installations are subject to codes established by
local utilities or other authorities having jurisdiction*
This jurisdiction normally covers electrical wiring, gas
piping, flue specification and insulation of adjacent
combustible material where required clearances can¬
not be maintained. As a practical guide, use the
American National Standard Installation of Gas Ap¬
pliances and Piping Z21.30, and Bryant Form No.

that all equipment furnished meets the requirements
of the installation. Any lubricant or pipe dope used ,
for gas valve or gas pipe connections,' shall be
resistant to the action of propane.
LOCATING THE BOILER
The boiler should be centrally Ipcated with respect to
the distribution system and as close to the chimney as
possible.
This boiler is not intended for use on combustible
.fL.o.Qrs....When selecting the installation site, remember .
it must have a firm, noncombustible level foundation.
Construct a level concrete pad if necessary. If the
boiler base is not level, the sections will not align
properly and assembly difficulties will be encoun¬
tered.
If the Model 246 is to be used as a steam boiler and is
to be connected to' another steam boiler, the factory
design waterlines of the two boilers must be equal
distance above floor level.
