INSTALLATION

Continued

CAUTION:Useonlynew,black ironorsteelpipe.Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" diameter orgreatertoallowpropergasvolume 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 13).

IMPORTANT: Install equipment 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 fireplaces.

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 heater 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. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contami- nants. This keeps them from going into heater controls. If sediment trap is not installed or is installed 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.

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping and connections, internal and external to unit, for leaks after installing or servicing. Correct 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.

CAUTION: Make sure external regulator has been installed between propane/LP supply and heater.SeeguidelinesunderConnecting to Gas Supply, page 13.
