Installation must include a manual shutoff valve, ground joint union, plugged 1/8"
NPT tap and a sediment trap. Locate NPT tap within reach for test gauge hook up.
NPT tap must be upstream from heater (see Figure 7).
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.

CAUTION
Use pipe joint sealant that is resistant to liquid petro-
leum (LP) gas.
Install sediment trap in supply line as shown in Figure 7. 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:
Use two pipe wrenches when connecting gas piping to gas control
valve of heater. This will prevent turning or damaging control valve.

* An A.G.A. design-certified manual shutoff valve with 1/8" NPT tap is an
acceptable alternative to test gauge connection. Purchase the optional A.G.A.
