We recommend that you install a sediment trap in
supply line as shown in Figure 22. Locate sediment
trap where it is within reach for cleaning. Install in
piping system between fuel supply and replace.
Locate sediment trap where trapped matter is not
likely to freeze. A sediment trap traps moisture
and contaminants. This keeps them from going
into replace gas controls. If sediment trap is not
installed or is installed wrong, replace may not
run properly.
INSTALLATION
Continued
For propane/LP units, 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
water. If you do not reduce incoming gas pres-
sure, heater regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 21. Pointing the vent down
protects it from freezing rain or sleet.
CAUTION: Use only new,

Installation must include an 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 replace (see Figure 22).
IMPORTANT: Install equipment shutoff valve
in an accessible location. The equipment shutoff
valve is for turning on or shutting off the gas to
the appliance.
Check your building codes for any special re-
quirements for locating equipment shutoff valve
to replaces.
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 replace valves. Never use sealant on
are threads.
