INSERT INSTALLATION
CHECK GAS TYPE
Use proper gas type for the insert you are installing. If you have conflicting gas type,
do not install insert. See dealer where you purchased the insert for proper insert ac-
cording to your gas type.
INSTALL GAS PIPING TO INSERT LOCATION
WARNING
A qualified installer or service person
must connect appliance to gas supply.
Follow all local codes.
CAUTION
For propane/LP units, never connect insert directly to the propane/
LP supply. This burner system requires an external regulator (not
supplied). Install the external regulator between the burner system
and propane/LP supply.
INSTALLATION ITEMS NEEDED
Make sure you have the items listed below before installing appliance.
• External regulator (supplied by installer) • Piping (check local codes) • Test gauge connection*
• Sealant (resistant to propane/LP gas) • Sediment trap (optional but recommended)
• Tee joint • Pipe wrench
• approved flexible gas line with gas connector (if allowed by local codes — not provided)
* A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA design-certified equipment shutoff valve from your dealer.
For propane/LP connections only, the installer must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure to between 11 and 13 inches of water. If you do
not reduce incoming gas pressure, burner system regulator damage could occur. Install external regulator with
the vent pointing down as shown in Figure 12. Pointing the vent down protects it from freezing rain or sleet.

CAUTION
Use only new black iron or steel pipe. Inter-
nally tinned copper or copper tubing can be
used per National Fuel Gas Code, Section
2.6.3, providing gas meets hydrogen sulfide
limits, and where permitted by local codes.
Gas piping system must be sized to provide
minimum inlet pressure (listed on data plate)
at the maximum flow rate (BTU/hr). Undue
pressure loss will occur if the pipe is too
small.

ILDV30/ILDV20 Fireplace Insert INSERT INSTALLATION
WARNING
Only persons licensed to work with gas
piping may make the necessary gas con-
nections to this appliance.
CAUTION
A manual shut-off valve is factory installed
upstream of the appliance. Union tee and
plugged 1/8" NPT pressure tapping point
should be installed upstream of the appli-
ance. Figure 13
A listed manual shutoff is factory installed upstream of appliance. Union tee and
plugged 1/8" NPT pressure tapping point should be installed upstream of the appli-
ance. Figure 13.
IMPORTANT: The main gas valve is for turning on or
shutting off the gas to the insert.
Check your building codes for any special requirements
for locating equipment shutoff valve to inserts.
Apply pipe joint sealant lightly to threads. This will
prevent excess sealant from going into pipe. Excess
sealant in pipe could result in clogged burner system valves.
We recommend that you install a sediment trap/drip leg in supply line as shown in
Figure 13. Locate sediment trap/drip leg where it is within reach for cleaning. Install
in piping system between fuel supply and burner system. Locate sediment trap/drip
leg where trapped matter is not likely to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going into the burner system gas controls. If
sediment trap/drip leg is not installed or is installed wrong, burner system may not
run properly.
NOTE : The gas line connection may be made using 1/2" rigid tubing or an
approved flex connector. Since some municipalities have additional local codes
