will be maintained at all times�
WARNING: You must secure this appliance to fire-
place floor. If not, appliance will move when you adjust
controls. Moving appliance may cause a gas leak.
WARNING: If installing in a sunken fireplace, spe-
cial care is needed. You must raise the fireplace floor
to allow access to appliance control panel. This will
ensure adequate air flow and guard against sooting
and controls being damaged. Raise fireplace floor
with noncombustible material. Make sure material
is secure.

CONNECTING TO GAS SUPPLY
WARNING: This appliance requires a 1/2" NPT
(National Pipe Thread) inlet connection to the pres-
sure regulator.
WARNING: A qualified service person must con-
nect appliance to gas supply. Follow all local codes.
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in cer-
tain areas. Check your local codes. Use pipe of 1/2"
diameter or greater to allow proper gas volume to
appliance. If pipe is too small, undue loss of volume
will occur.
CAUTION: Never connect propane/LP appliance
directly to the propane/LP supply. This appliance
requires an external regulator (not supplied). Install
the external regulator between the appliance and
propane/LP supply.
Installation Items Needed
Before installing appliance, make sure you have the items listed below�
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
WARNING: Never connect this appliance to private
(non-utility) gas wells. This gas is commonly known
as wellhead gas and does not have odorants and may
have impurities, and variations in BTU content. The
use of well-head gas will void the manufacturer’s
warranty to this appliance.
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 appliance (see Figure 12,
Page 10)�
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�
Check your building codes for any special requirements for locating
equipment shutoff valve to appliances�
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 clogged appliance valves�
When an appliance is for connection to a fixed piping
system, the installationmust conform with localcodes,
or in the absence of local codes with the National Fuel
Gas Code, ANSI Z223.1 • NFPA 54; National Fuel Gas
Code; Natural Gas and Propane Installation Code, CSA
B149.1; or Propane Storage and Handling Code, CSA
B149.2, as applicable.
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connector (if allowed by local
codes) (not provided)
* An equipment shutoff valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection� Purchase the optional equip-
ment shutoff valve from your dealer�
For propane/LP units, 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 14" of water� If you
do not reduce incoming gas pressure, appliance regulator damage
could occur� Install external regulator with the vent pointing down as
shown in Figure 11� Pointing the vent down protects it from freezing
rain or sleet�

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1� Disconnect appliance with its appliance main gas valve (control
valve) and equipment shutoff valve from gas supply piping system�
Pressures in excess of 1/2 psig will damage appliance regulator�
2� Cap off open end of gas pipe where equipment shutoff valve was
connected�
3� Pressurize supply piping system by either opening propane/LP sup-
ply tank valve for propane/LP gas or opening main gas valve located
on or near gas meter for natural gas or using compressed air�
4� Check all joints of gas supply piping system� Apply noncorrosive
leak detection fluid to all joints� Bubbles forming show a leak�
5� Correct all leaks at once�
6� Reconnect appliance and equipment shutoff valve to gas supply�
Check reconnected fittings for leaks�
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1� Close equipment shutoff valve (see Figure 13).
2� Pressurize supply piping system by either opening propane/LP
supply tank valve for propane/LP gas or opening main gas valve
located on or near gas meter for natural gas or using compressed
air�
3� Check all joints from gas meter to equipment shutoff valve for
natural gas or propane/LP supply to equipment shutoff valve
for propane/LP (see Figure 14 or Figure 15, Page 11). Apply
noncorrosive leak detection fluid to all joints� Bubbles forming
show a leak�
4� Correct all leaks at once�
PRESSURE TESTING APPLIANCE GAS CONNECTIONS
1� Open equipment shutoff valve (see Figure 13)�
2� Open main gas valve located on or near gas meter for natural gas
or open propane/LP supply tank valve�
3� Make sure control knob of appliance is in the OFF position�
4� Check all joints from gas meter to equipment shutoff valve for
natural gas or propane/LP supply to equipment shutoff valve for
propane/LP (see Figure 14 or Figure 15, Page 11). Apply noncor-
rosive leak detection fluid to all joints� Bubbles forming show a leak�
5� Correct all leaks at once�
6� Light appliance (see Operation, Page 15)� Check all other internal
joints for leaks�
7� Turn off appliance (see To Turn Off Gas to Appliance, Page 15).

CAUTION: Avoid damage to gas control. Hold gas
control with wrench when connecting it to gas piping
and/or fittings.
We recommend that you install a sediment trap in supply line as
shown in Figure 12� Locate sediment trap where it is within reach for
cleaning� Install in piping system between fuel supply and appliance�
Locate sediment trap where trapped matter is not likely to freeze� A
sediment trap traps moisture and contaminants� This keeps them
from going into appliance controls� If sediment trap is not installed
or is installed wrong, appliance may not run properly�
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections,
internal and external to unit, for leaks after installing
or servicing. Correct all leaks at once.
WARNING: Never use an open flame to check for
a leak. Apply a noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak. Correct all
leaks at once.
CAUTION: Make sure external regulator has been
installed between propane/LP supply and appliance.
See guidelines under Connecting to Gas Supply,
Page 9.
PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
The appliance and its appliance main gas valve must be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of 1/2 psi (3�5 kPa)�
The appliance must be isolated from the gas supply piping system
by closing its equipment shutoff valve during any pressure testing of
the gas supply piping system at test pressures equal to or less than
1/2 psi (3�5 kPa)�
