between the heater and propane/LP supply.
Installation Items
Before installing heater, 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 *
• ground joint union
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* A CSA design-certified equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge connection. The
optional CSA design-certified equipment shutoff valve can be
purchased from your dealer. See Accessories, page 18.
If installing to a fixed fuel piping system, the installation must
conform with local codes or, in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1.
If the heater will be connected to a permanent gas source, 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 inches of water. If you do not reduce incoming gas
pressure, heater regulator damage could occur. Install the external
regulator with the vent pointing down as shown in Figure 12. 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 large
enough diameter to allow proper gas volume to heater.
If pipe is too small, undue loss of volume will occur.
