CONNECTING

 

 

NOTICE

 

A qualified service person must connect fireplace to gas supply.

TO GAS

 

 

Follow all local codes.

WARNING ICON

G 001WARNING

 

 

 

 

 

 

 

Never connect fireplace to private (non-utility) gas wells. This gas is

 

 

commonly known as wellhead gas.

 

 

 

 

IMPORTANT: Check gas line pressure before connecting fireplace to gas line. Gas

 

line pressure must be no greater than 14 inches of water. If gas line pressure is

 

higher, fireplace regulator damage could occur.

 

 

 

 

 

 

WARNING ICON

G 001CAUTION

 

 

 

 

 

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" or greater diameter 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).

 

 

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.

 

 

 

 

 

 

WARNING ICON

G 001CAUTION

 

 

Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

 

 

 

 

Install sediment trap in supply line as shown in Figure 16. 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 controls. If sediment trap is not installed or is installed wrong, fireplace may not run properly.
