tee joint

sealant (resistant to propane gas)

pipe wrench

manual shutoff valve *

approved flexible gas line with

test gauge connection *

 

gas connector (if allowed by

sediment trap

 

local codes) (not provided)

WARNING

WARNING ICON

G 001

Never connect fireplace to private (non-utility) gas wells. This gas is commonly known as well-head gas.

CAUTION

WARNING ICON

G 001

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.

CAUTION

WARNING ICON

G 001

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.
