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.
For propane/LP installations, the installer must
supply an external regulator. The external
regulator will reduce incoming gas pressure.
You must reduce incoming gas pressure to
between 11" and 14" of w.c. If you do not re-
duce incoming gas pressure, heater regulator
damage could occur. Install external regulator
with the vent pointing down as shown in Figure
11. Pointing the vent down protects it from
freezing rain or sleet.
For both gas types, install sediment trap in
supply line as shown in Figure 10. Place
sediment trap where it is within reach for
cleaning. Place 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 sedi-
ment trap is not installed or is installed wrong,
heater may not run properly.
