tents for shipping damage and immediately inform your dealer if any damage is found. Do
not install any unit with damaged, incomplete, or substitute parts. Check your packing list to
verify that all listed parts have been received.
The following factors should be taken into consideration:
• This insert should have sufcient access for its safe operation and maintenance.
• The ow of combustion and ventilation air must not be obstructed.
• Minimum clearances to combustibles, such as mantels, must be maintained. Refer to Pages
8 and 9, Figures 3, 4 and 5.
• Never obstruct the front opening of the insert.
• Do not install in the vicinity where gasoline or other ammable liquids may be stored.
• These units can be installed in a bedroom. Refer to National Fuel Gas Code ANSI Z233.1/
NFPA 54 (current edition), the Uniform Mechanical Code (current edition), and Local Build-
ing Codes for specic installation requirements.

Before installing the gas replace insert, consider the functioning needs of the replace. Con-
rm the size of the replace cavity, the design of the chimney, and the availability of the gas
supply and electricity for the insert fan.
When the unit is installed into a wood burning replace, the minimum distance the mantel
can be placed above the replace is governed by local building codes applicable to wood
burning replaces. Consult local authorities having jurisdiction for these clearances. The
underside of the mantel will become warm. Use only nishes which are heat resistant and
do not discolor.
The dimensions shown on Pages 8 and 9, Figures 3 and 4, are mini-
mum clearances to maintain when installing this heater. Follow these
instructions carefully to ensure safe installation. Failure to follow
instructions exactly can create a re hazard.

Use proper gas type for the insert you are installing. If you have conicting gas type, do not
install insert. See dealer where you purchased the insert for proper insert according to your
gas type.
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 27. Pointing the vent down protects it from freezing
rain or sleet.

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 28
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 28. 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.
