Gas Supply &
Connections
NOTICE: A qualified technician must
¦
connect the heater to the gas supply
and leak test the unit before it is
approved for use. Consult all codes.
¦ WARNING: The unit must be installed
and connected in accordance with local
codes, or in the absence of local codes,
with the most current edition of the
National Fuel Gas Code ANSI Z223.1
(NFPA 54) or
Installation Code.
We recommend using new black iron or
steel pipe only. Internally tinned copper
tubing can be used in some areas when
permitted by local codes. Only use pipe of
½" or greater diameter to allow full gas
volume to heater, without undue loss of
pressure. Excessive pressure loss will occur
if the pipe is too small.
CAN/CGA B149
The gas supply line must include a manual
shut-off valve and union so the unit can be
disconnected for servicing. Also a sediment
trap and a 1/8" N.P.T. plugged tapping must
be installed upstream of the heater. The
sediment trap is installed to prevent moisture
and contaminants from passing through the
pipe to the heater controls and burners.
Failure to install a sediment trap could
prevent the heater from operating reliably.
The 1/8" N.P.T. plugged tapping is installed
for the test gauge connection (immediately
upstream of the gas supply connection).
Damage to the valve caused by lack of a
sediment trap will not be covered by the
warranty.
We have supplied a 24" flexible stainless
steel gas line for installation convenience
and to avoid undue mechanical load on the
valve. We recommend using the flexible
line, but also refer to local code. The gas
supply line connection is made to the
flexible line in the lower rear right portion of
the Windsor Bay. Apply a thread sealant to
both male ends on the flexible gas line.
