AIR FOR
COMBUSTION AND
VENTILATION
WARNING: This appliance
shall not be installed in a confined space or unusually tight
construction unless provisions
are provided for adequate combustion and ventilation air. Read
the following instructions to insure proper fresh air for this and
other fuel-burning appliances in
your home.
Today’s homes are built more energy efficient than ever. New materials, increased
insulation, and new construction methods
help reduce heat loss in homes. Home owners
weather strip and caulk around windows and
doors to keep the cold air out and the warm air
in. During heating months, home owners
want their homes as airtight as possible.
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper combustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and
fuel burning appliances draw air from the
house to operate. You must provide adequate fresh air for these appliances. This
will insure proper venting of vented fuelburning appliances.
INSTALLATION
NOTICE: Installation, service, and
repair of this appliance must be
performed by a qualified installer,
service agency, company or gas
supplier experienced with this
type of gas appliance. Only factory authorized components listed
in these instructions may be used
in accordance with the
manufacturer’s instructions and
all codes and requirements of the
authority having jurisdiction. Any
modifications to this kit, or use of
unauthorized components or accessory items will void the
manufacturer’s warranty, and may
result in a hazardous condition.

CAUTION: Use only 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, undue 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 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.
CHECKING GAS
CONNECTIONS
WARNING: Test all gas piping and connections for leaks
after installing or servicing. Correct all leaks at once.
