INSTALLING DAMPER
CLAMP
Secure the damper stop clamp provided to
the leading edge of the damper as shown in
Figure 5. If for any reason this clamp doesn't
work on your fireplace, another suitable
clamp or permanent stop must be installed,
or the damper blade must be cut or removed.

WARNING: Test all gas pip-
ing and connections for leaks
after installing or servicing. Cor-
rect all leaks at once.
WARNING: Never use an
open flame to check for a leak.
Apply a mixture of liquid soap
and water to all joints. Bubbles
forming show a leak. Correct all
leaks at once.
CHECKING GAS
CONNECTIONS
Pressure Testing Gas Supply
Piping System
Test Pressures In Excess Of 1/2 PSIG
1. Disconnect log set and its individual
manual shutoff valve from gas supply
piping system.
2. Cap off open end of gas pipe where
manual 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 mixture of liquid soap
and water to gas joints. Bubbles form-
ing show a leak.
5. Correct all leaks at once.
6. Reconnect log set and manual shutoff
valve to gas supply. Check reconnected
fittings for leaks.
CONNECTING TO GAS
SUPPLY
WARNING: A qualified ser-
vice person must connect log set
to gas supply. Follow all local
codes.
Installation Items Needed
Before installing log set, make sure you
have the items listed below.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• manual shutoff valve
• adjustable (crescent) wrench or pliers
• sediment trap
• tee joint
• pipe wrench
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-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 log set. If
pipe is too small, undue loss of
pressure will occur.
Install sediment trap in supply line as shown
in Figure 6. 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 log set controls. If sediment trap is not
installed or is installed wrong, log set may
not run properly.
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
log set (see Figure 6).
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in a clogged burner injector.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
