CONNECTING TO GAS SUPPLY

Manual background WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pres- sure regulator.

Manual backgroundWARNING:Aqualifiedservicepersonmustconnect appliance to gas supply. Follow all local codes.

Manual background CAUTION: Never connect propane/LP fireplace directly to the propane/LP supply. This unit requires an external regulator (not supplied).Install the external regulator between the unit and propane/LP supply.

Manual backgroundWARNING: Never connect natural gas fireplace to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

Installation Items Needed

Before installing appliance, 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) (provided)

*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 22.

For propane/LP units, the installer must supply an external regu- lator. 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, regulator dam- age could occur. Install external regulator with the vent pointing down as shown in Figure 8 page 9. Pointing the vent down protects it from freezing rain or sleet.

Manual background CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in cer- tain areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to appliance. If pipe is too small, undue loss of volume will occur.
