IMPORTANT: For natural gas, check gas line
pressure before connecting replace to gas
line. Gas line pressure must be no greater
than 14" of water. If gas line pressure is higher,
heater regulator damage could occur.
CAUTION: Never connect

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 pressure, replace regulator
damage could occur. Install external regula-
tor with the vent pointing down as shown in
Figure 21. Pointing the vent down protects it
from freezing rain or sleet.

Installation must include an equipment shutoff
valve, union, and plugged 1/8" NPT tap. Lo-
cate NPT tap within reach for test gauge hook
up. NPT tap must be upstream from heater
(see Figure 22, page 18).
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
requirements 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.
