CONNECTING TO GAS
SUPPLY
WARNING: A qualified ser-
vice person must connect heater
to gas supply. Follow all local
codes.
IMPORTANT:
Check gas line pressure be-
fore connecting heater to gas line. Gas line
pressure must be no greater than 14 inches
of water. If gas line pressure is higher,
heater regulator damage could occur.
Installation must include an equipment shutoff
valve, ground joint union, and plugged
1/8" NPT tap. Locate NPT tap within reach
for test gauge hook up. NPT tap must be
upstream from heater (see Figure 12).
IMPORTANT:
Install an equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or
shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged heater valves.
Install sediment trap (trap) in supply line as
shown in Figure 12. Locate sediment trap
where it is within reach for cleaning. Locate
sediment trap where trapped matter is not
likely to freeze. A sediment trap traps mois-
ture and contaminants. This keeps them
from going into heater controls. If sediment
trap is not installed or is installed wrong,
heater may not run properly.
IMPORTANT:
Hold pressure regulator
with wrench when connecting it to gas pip-
ing and/or fittings.
CAUTION: Use only new,
black iron or steel pipe. Internally-
tinned copper tubing may be used
in certain areas. Check your local
codes. Use pipe 3/8" diameter or
greater to allow proper gas
volume to heater. If pipe is too
small, undue loss of pressure will
occur.
WARNING: Never connect
heater to private (non-utility) gas
wells. This gas is commonly
known as wellhead gas.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
