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
(3.5 kPa)
1. Disconnect appliance with its appliance
main gas valve (control valve) and equip-
ment shutoff valve from gas supply pip-
ing system. Pressures in excess of 1/2
psig will damage heater regulator.
2. Cap off open end of gas pipe where
equipment shutoff valve was con-
nected.
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 equipment
shutoff valve to gas supply. Check re-
connected 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)
• equipment shutoff valve
• test gauge connection
• 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.
We recommend that you install a sediment
trap in supply line as shown in Figure 6.
Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and heater. Locate sedi-
ment 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 an equipment
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).
IMPORTANT:
Install equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or
shutting off the gas to the appliance.
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.
