Installation Items Needed
Before installing appliance, make sure you have the
items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved fl exible gas line with gas connector (if
allowed by local codes) (not provided)
* An equipment shutoff valve with 1/8" NPT tap is
an acceptable alternative to test gauge connection.
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, appli-
ance regulator damage could occur. Install external
regulator with the vent pointing down as shown in
Figure 13. Pointing the vent down protects it from
freezing rain or sleet.
CAUTION: Use only new, black
iron or steel pipe. Internally-tinned
copper tubing may be used in certain
areas. Check your local codes. Use
pipe of 1/2" diameter or greater to
allow proper gas volume to heater.
If pipe is too small, undue loss of
volume will occur.
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 appliance (see Figure 14).
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 require-
ments for locating equipment shutoff valve to
appliances.
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
appliance valves.

WARNING: Use pipe joint sealant
that is resistant to liquid petroleum
(LP) gas.

We recommend that you install a sediment trap in
supply line as shown in Figure 14, Page 14. Locate
sediment trap where it is within reach for cleaning.
Install in piping system between fuel supply and
appliance. Locate sediment trap where trapped
matter is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them from
going into appliance controls. If sediment trap is
not installed or is installed wrong, appliance may
not run properly.
