The upflow/horizontal furnace is shipped standard for left side
installation of gas piping. An opening with plug is provided on the right
side for an alternate gas piping arrangement.
The installation of piping shall be in accordance with piping codes and
the regulations of the local gas company. Pipe joint compound must be
resistant to the chemical reaction with liquefied petroleum gases.
Important:
If local codes allow the use of flexible gas appliance
connector, always use a new listed connector. Do not use
a connector which has previously serviced another gas
appliance.
Refer to the piping table for delivery sizes. Connect gas supply to the
unit, using a ground joint union and a manual shut-off valve. National
codes require a condensation drip leg to be installed ahead of the gas
valve.
The furnace and its individual shut-off valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa).
The furnace must be isolated from the gas supply piping by closing its
individual manual shut-off valve during any pressure testing of the
gas supply piping system at test pressures equal to or less than 1/2
psig (3.5 kPa).
Note:
Maximum pressure to the gas valve for natural gas is 13.8" W.
C. Minimum pressure is 5.0" W.C. Maximum pressure to the
gas valve for propane is 13.8" W.C. Minimum pressure is 11.0"
W.C.

All gas fittings must be checked for leaks using a soapy solution before
lighting the furnace.
DO NOT CHECK WITH AN OPEN FLAME!
For propane conversions on all S-Series Furnaces, use BAYLPSS400*
conversion kit with stainless steel burners.
When installing our furnaces in a manufactured house, use
Manufactured Housing Accessory Kit, BAYMFGH200B.
