INSTALLATION
In compliance with ANSI Z21.60•CGA2.26 and Nation-
al Fuel Gas Code, Section 6.
BEFORE INSTALLING THE APPLIANCE
- Turn off gas supply to fireplace or firebox.
- Clean fireplace floor and chimney before installing log
set. Seal any ash. Clean out doors to protect
the unit from down drafts.
WARNING:Before installing this appliance, have
the fireplace and chimney professionally cleaned to re-
move any ashes, soot, creosote, or other obstructions.
Perform this cleaning annually after installation.
Installation and Gas Connection (See Fig. 5)
1. Place the burner pan assembly in the center of the
fireplace floor. Make sure the front of pan faces forward.
2a. Thread the keyed shut-off valve to the fireplace gas
supply pipe. Use thread sealant.
2b. If a keyed shut-off valve is already installed, thread
1/2" female connector to the fireplace gas supply pipe.
Use thread sealant.
3. Thread adapter fitting into keyed shut-off valve (or
1/2" Female Connector).
4. Install 3/8" orifice fitting onto the burner inlet fitting
using thread sealant on male threads of burner
inlet fitting.
5. Install the gas flex tube to the adapter fitting.
Carefully shape tube to attach to orifice fitting.
CONNECTION 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 natural gas)
• equipment shutoff valve
• test gauge connection
• adjustable (crescent) wrench or pliers
• sediment trap
• tee joint
• pipe wrench
CAUTION: Only use a 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,
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 6).
Step 2a: Keyed shut-off valve
Step 2b: 1/2" Female Connector
IMPORTANT: Install equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or shut-
ting 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.
Install sediment trap in supply line as shown
in Figure 6. Locate sediment trap where it is
within reach for cleaning. 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 incorrectly, log set
may not run properly.
