Connecting To Gas Supply - Vanguard VMH26TN Owner's Operation And Installation Manual

CONNECTING
TO GAS
SUPPLY
16
A qualified service person must connect fireplace to gas supply.
Follow all local codes.
Never connect fireplace to private (non-utility) gas wells. This gas is
commonly known as wellhead gas.
Check gas line pressure before connecting fireplace to gas line. Gas
IMPORTANT:
line pressure must be no greater than 14 inches of water. If gas line pressure is
higher, fireplace regulator damage could occur.
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.
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.
