CONNECTING TO GAS SUPPLY

WARNING: A qualified service 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

Installation must include a 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 NPT threads. This will
prevent excess sealant from going into pipe. Excess sealant in pipe
could result in a clogged burner injector.

WARNING: Use pipe joint sealant that is resistant

to liquid petroleum (LP) gas.

We recommend that you install a sediment trap in supply line as
shown in Figure 4. Locate sediment trap where it is within reach for
cleaning. Install in piping system between fuel supply and heater.
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 wrong, log set may not run properly.

Propane/LP Gas Conversion

To convert to propane/LP gas, the burner inlet fitting and pilot orifice
must be replaced. The propane/LP burner inlet fitting is supplied with
the orifice installed for a 24" log set. If you have an 18" or 30" set, you
must change this orifice also. See Figure 1, page 3 for product
identification.

Burner Inlet Fitting

1. Remove the burner inlet fitting from the burner pan assembly.
DO NOT remove the orifice from this fitting. The propane/LP
burner inlet fitting is included in the hardware kit (see Figure 12).

2. Be sure to use the correct orifice for your appliance. The hard­ware kit included with this appliance contains two orifices with
a cone-like shape. If you have an 18" set, the orifice for the
burner inlet fitting is red; for a 30" set, it is black. If you have
a 24" log set, the orifice is already installed inside the fitting.

3. For an 18" or 30" set, use a 10mm socket or nut driver to re­move the orifice from the propane/LP burner inlet fitting.
Choose the correct orifice for your log set size and install in
place of the orifice you just removed.

4. Using thread sealant (resistant to the action of propane/LP gas) on
larger end of fitting, screw the burner inlet fitting through hole
and into burner manifold (see Figure 13). Tighten using a wrench.

During the 2-3 hour appliance break-in period, you may detect
an odor from the appliance as the various paints and com­pounds used in the manufacturing of this log set cure. This is a
normal and temporary situation that is not cause for alarm.
However, you may want to provide extra ventilation to the room
during this time.

To ensure proper curing of the logs:

• Ignite a 2" flame and maintain it for 1 hour.

• Burn the logs in consecutive 1 hour periods raising the flame
an additional 2" to full flame height for a total of three hours.
