INSTALLATION

Continued

Installation Items Needed

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 *

•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. Purchase the optional CSA design-certified equipment shutoff valve from your dealer. See Accessories, page 30.

For propane/LP gas, 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 13. Pointing the vent down pro- tects it from freezing rain or sleet.

CAUTION:Useonlynew,black ironorsteelpipe.Internally-tinned copper tubing may be used in cer- tainareas.Checkyourlocalcodes. Usepipeof1/2"diameterorgreater to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.

Installation must include a 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 14). IMPORTANT: Install equipment shutoff valve in an accessible location. The main gas 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.

We recommend that you install 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. 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.Holdgasregulatorwith wrench when connecting it to gas piping and/or fittings.
