Installation Items Needed
Before installing heater, make sure you have
the items listed below.
external regulator (for propane/LP units
only, 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
* A equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge
connection. Purchase the optional equipment
shutoff valve from your dealer. See Acces-
sories, page 29.
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 re-
duce incoming gas pressure, heater 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.
