It is normal for replaces fabricated of steel to
give off some expansion and/or contraction noises
during the start up or cool down cycle. Similar
noises are found with your furnace heat exchanger
or car engine.
It is not unusual for gas replaces to give off some
odor the rst time it is burned. This is due to the
manufacturing process.
It is recommended that you burn your replace

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 exible gas line with gas connector (if allowed by local codes — not provided)
* A CSA design-certied equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test
gauge connection. Purchase the CSA design-certied 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 wa-
ter. 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 14. Pointing the vent down protects it from freezing
rain or sleet.

Use proper gas type for the replace you are installing. If you have conicting gas type, do not install
replace. See dealer where you purchased the replace for proper replace according to your gas
type.
When using copper or ex connectors use only ttings
approved for gas connections. The gas control inlet is
3/8" NPT.

IDV380/IDV490 Fireplace Insert
Figure 15
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 appliance. Figure 15.
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 15. 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
ex connector. Since some municipalities have additional local codes it is always best
to consult your local authorities and the current edition of the National Fuel Gas Code
ANSI.Z223.1, NFPA54. In Canada CSA-B149 (1 or 2) Installation Code.
