WARNINGS

WARNING: This product contains and/or generates

chemicals known to the State of California to cause
cancer or birth defects, or other reproductive harm.

WARNING: Keep fl ue open when operating unit.

IMPORTANT: Read this owner’s manual carefully
and completely before trying to assemble, operate,
or service this log set. Improper use of this log set
can cause serious injury or death from burns, fi re,
explosion, electrical shock, and carbon monoxide
poisoning.

DANGER: Carbon monoxide poisoning may lead

to death!

Carbon Monoxide Poisoning: Early signs of carbon monoxide

poisoning resemble the fl u, with headaches, dizziness, or nausea. If
you have these signs, the log set may not be working properly. Get
fresh air at once! Have log set serviced. Some people are more
affected by carbon monoxide than others. These include pregnant
women, people with heart or lung disease or anemia, those under
the infl uence of alcohol, and those at high altitudes.

Natural Gas: Natural gas is odorless. An odor-making agent is
added to the gas. The odor helps you detect a gas leak. However,
the odor added to the gas can fade. Gas may be present even though
no odor exists.

Make certain you read and understand all warnings. Keep this manual for
reference. It is your guide to safe and proper operation of this log set.

WARNING: Any change to this log set or its controls

can be dangerous.

CONNECTING TO GAS SUPPLY

WARNING: A qualifi ed 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

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 volume will occur.

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.
