We recommend that you install a sediment
trap (not supplied with log set) in supply line
as shown in Figure 4. Locate sediment trap
where it is within reach for cleaning. Install in
piping system between fuel supply and ap
-
pliance. Locate sediment trap where trapped
matter is not likely to freeze. A sediment trap
captures moisture and contaminants. This
keeps them from going into log set controls.
If sediment trap is not installed or is installed
wrong, log set may not run properly.

CHECKING GAS CONNECTIONS
WARNING: Test all gas piping
and connections, internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an
open flame to check for a leak.
Apply a noncorrosive leak detec-
tion fluid to all joints. Bubbles
forming show a leak. Correct all
leaks at once.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect log set and its individual equip
-
ment shutoff valve from gas supply piping
system.
2. Cap off open end of gas pipe where equip
-
ment shutoff valve was connected.
3. Pressurize supply piping system by either
using compressed air or opening main gas
valve located on or near gas meter.
4. Check all joints of gas supply piping system.
Apply noncorrosive leak detection fluid to
gas joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect log set and equipment shutoff
valve to gas supply. Check reconnected
fittings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see
Figure 5).
2. Pressurize supply piping system by either
using compressed air or opening main gas
valve located on or near gas meter.
3. Check all joints from gas meter to equip
-
ment shutoff valve (see Figure 5). Apply
noncorrosive leak detection fluid to gas
joints. Bubbles forming show a leak.
4. Correct all leaks at once.
