CAUTION: Use only new,
black iron or steel pipe. Inter-
nally tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
pressure will occur.
CAUTION: Check your gas
line pressure before connect-
ing heater to gas line. Gas line
pressure must be no greater than
10.5" of water. If gas line pres-
sure is higher, heater regulator
damage could occur.
CAUTION: Avoid damage to
regulator. Hold gas regulator
with wrench when connecting
into gas piping and/or fittings.
