FIREPLACE INSTALLATION Installing Gas Piping to Fireplace Location

FIREPLACE INSTALLATION

Continued

INSTALLING GAS PIPING TO FIREPLACE LOCATION

WARNING: A qualified service person must con- nect fireplace to gas supply. Follow all local codes.

CAUTION: For propane/LP units, never connect fireplace directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the fireplace and propane/LP supply.

Installation Items Needed

Before installing fireplace, 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

approved flexible gas line with gas connector (if allowed by local codes)

*ACSAdesign-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA design-certified equipment shutoff valve from your retailer.

For propane/LP connection only, the installer must supply an ex- ternal 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, fireplace regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 30. 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

1/2" inside diameter or greater to allow proper gas

volume to fireplace. 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 fireplace (see Figure 31).

IMPORTANT: Install main gas valve (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 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 fireplace valves.

 

WARNING: Use pipe joint sealant that is resistant

to liquid petroleum (LP) gas.

 

We recommend that you install a sediment trap/drip leg in supply

line as shown in Figure 31. Locate sediment trap/drip leg where it

is within reach for cleaning. Install in piping system between fuel

supply and fireplace. Locate sediment trap/drip leg where trapped

matter is not likely to freeze. A sediment trap traps moisture and

contaminants. This keeps them from going into fireplace gas con-

trols. If sediment trap/drip leg is not installed or is installed wrong,

fireplace may not run properly.
