For propane/LP units, 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 pressure,
replace regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 18. 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 19).
IMPORTANT: Install an equipment shutoff valve
in an accessible location. The equipment shutoff
valve is for turning on and 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.

We recommend that you install a sediment trap in
supply line as shown in Figure 19. 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 re-
place controls. If sediment trap is not installed or is
installed wrong, replace may not run properly.
* Purchase the optional CSA design-certified
equipment shutoff valve from your dealer. See
Accessories, page 27.
