INSTALLATION
Continued
For propane/LP units, the installer must supply an external regulator. The external regulator will re- duce incoming gas pressure. You must reduce in- coming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pres- sure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 15. Pointing the vent down pro- tects it from freezing rain or sleet.
CAUTION: Use only new, black iron or steel pipe. Inter-
We recommend that you install a sediment trap in supply line as shown in Figure 16. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Lo- cate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and con- taminants. This keeps them from going into heater controls. If sediment trap is not installed or is in- stalled wrong, heater may not run properly.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting it to gas piping and/or fittings.
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 heater (see Figure 16).

IMPORTANT: Install equipment valve in an acces- sible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.
Check your building codes for any special re- quirements for locating equipment shutoff valve to fireplaces.
Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from go- ing into pipe. Excess sealant in pipe could result in clogged heater valves.
WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

CHECKING GAS CONNECTIONS
WARNING: Test all gas pip- ing and connections, internal and external to unit, for leaks after installing or servicing. Cor- rect all leaks at once.
WARNING:Neveruseanopen flame to check for a leak. Apply a noncorrosive leak detection fluid toalljoints.Bubblesformingshow a leak. Correct all leaks at once.
