We recommend that you install a sediment trap/
drip leg in supply line as shown in Figure 38. Lo-
cate sediment trap/drip leg where it is within reach
for cleaning. Install in piping system between fuel
supply and replace. Locate sediment trap/drip leg
where trapped matter is not likely to freeze. A sedi-
ment trap traps moisture and contaminants. This
keeps them from going into replace gas controls.
If sediment trap/drip leg is not installed or is in-
stalled wrong, replace may not run properly.

1. Disconnect replace and its individual equip-
ment shutoff valve from gas supply piping
system. Pressures in excess of 1/2 psig (3.5 kPa)
will damage replace gas regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas replace or opening main gas
valve located on or near gas meter for natural
gas replace or using compressed air.
3. Attach exible gas line from gas supply to
control valve (see Figure 39).
4. Check all gas connections for leaks. See
Checking Gas Connections.
