VENTING SPECIFICATIONS
FOR INSTALLATION
The fireplace chimney flue and vent
must be drafting properly. To check the
vent for proper drafting, light a tightly
rolled newspaper on one end and place
it at the inside front edge of the fireplace.
Observe the smoke and be sure the
vent is properly drawing it up the
chimney. If the smoke spills out into the
room, extinguish the flame and remove
any obstruction until proper venting is
achieved. The chimney flue must remain
open a minimum of 3" at all times during
the operation of this log set.
WARNING: A qualified service
person must connect log set to gas
supply. Follow all local codes.
CHECK GAS TYPE
Use only natural gas. If your gas supply is
not natural gas, you must install On/Off
Valve/Safety Pilot Kit (see Accessories, page
6). Call dealer where you bought log set.
If the fireplace does not have a gas supply
shutoff valve, one must be installed.

have the items listed below.
●
piping (check local codes)
●
sealant (resistant to natural gas)
●
equipment shutoff valve
●
test gauge connection
●
adjustable (crescent) wrench or pliers
●
sediment trap
●

INSTALLING DAMPER CLAMP
Secure the damper stop clamp provided
to the leading edge of the damper as
shown in Figure 3. 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.
CAUTION: Only use a 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" diameter or greater to
allow proper gas volume to log
set. If pipe is too small, loss of
pressure will occur.
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 4).
IMPORTANT: Install equipment shutoff
valve in an accessible location. The
equipment 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 sealant
that is resistant to natural gas.
Install sediment trap in supply line as
shown in Figure 4. 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 incorrectly, log set may not
run properly.
CHECKING GAS CONNECTIONS
WARNING:
Test all gas
piping and connections for leaks
after installing or servicing.
Correct all leaks immediately.
Figure 4 –Gas connection
*
Purchase the optional CSA design-certified
equipment shutoff valve from dealer. See
Accessories pages 6.
** Minimum inlet pressure for purpose of
input adjustment.
.
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 immediately.
