Installation must include equipment shutoff
valve, 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 13).
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.
Check your building codes for an special
requirements for locating equipment shutoff
valve to heater.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could
result in clogged heater valves.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
Install sediment trap in supply line as shown
in Figure 13. 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 moisture 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 the pressure regulator
with wrench when connecting it to gas pip
-
ing and/or fittings. Do not over tighten pipe
connection to regulator. The regulator body
could be damaged.
