INSTALLING GAS PIPING TO FIREPLACE LOCATION

A qualified service person must connect fireplace to gas supply.
Follow all local codes.
Installation Items Needed
Before installing fireplace, make sure you have the items listed below.
• piping (check local codes)
• sealant (resistant to LP/propane gas)
• manual shutoff valve *
• test gauge connection *
• sediment trap
* An A.G.A. design-certified manual shutoff valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Purchase the optional A.G.A. design-certified manual
shutoff valve from your dealer. See Accessories, page 34.
Never connect fireplace to private (non-utility) gas wells. This gas is
commonly known as well-head gas.
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" diameter or greater to allow proper gas volume to
fireplace. If pipe is too small, undue loss of pressure will occur.
Installation must include a manual 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 16, page 17).
Check your building codes for any special requirements for locating manual shutoff
valve to fireplaces.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe could result in clogged fireplace
valves.
Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
Install sediment trap in supply line as shown in Figure 16, page 17. Locate sediment
trap where it is within reach for cleaning. Locate sediment trap where trapped
matter is not likely to freeze. A sediment trap traps moisture and contaminants. This
keeps them from going into fireplace gas controls. If sediment trap is not installed
or is installed wrong, fireplace may not run properly.
NOTICE
• tee joint
• pipe wrench
• approved flexible gas line with
gas connector (if allowed by
local codes) (not provided)
