CAUTION: Do not connect
appliance before pressure test-
ing gas piping. Damage to gas
valve may result and an unsafe
condition may be caused.
The appliance and it’s individual shutoff valve
must be disconnected from 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 individual
manual 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).
For the purpose of input adjustment two
pressure taps (for IN and OUT pressures)
are provided on the gas control valve for test
gauge connections to the appliance.
Flush installations are recommended where
living space is limited or at a premium and
since the space required to enclose the ap-
pliance would be located beyond an outside
wall, this would also reduce the cutting of
joists, roof rafters and such. Check local
codes for any restrictions.
Projected installations can extend any
distance into the room. A projection may
be ideal for a new addition on an existing,
finished wall.
Corner installations make use of space
that may not normally be used and provides
a wider and more efficient range for radiant
heat transference.
Internal wall installations provide a discreet
option for room separation and can also be
ideal as an addition to an existing wall.
SELECTING LOCATION
To determine the safest and most efficient
location for your appliance, you must take into
consideration the following guidelines:
1. The location must allow for proper clear-
ances (see Clearances, page 7).
2. Consider a location where heat output
would not be affected by drafts, air con-
ditioning ducts, windows or doors.
3. A location that avoids the cutting of joists
or roof rafters will make installation easier.
Figure 1 shows a plan view of a few com-
mon locations.

VENTING INSTALLATION
60° or greater. The total vertical height in this
example represents the minimum height of 8
feet and therefore the allowable lateral is 6
feet when the 75% rule applies. If the lateral
length must exceed 75% then the system
must be sized in accordance with Category I
venting tables.
Example 2: Shows a multiple offset each at
45° of inclination. Multiple offsets are permit-
ted if they do not exceed 45° of inclination. The
total lengths of the two offsets are not required
to meet the 75% allowable rule.
Example 3: Shows a single offset at 45° of
inclination and therefore the lateral length at
10 feet of offset does not have to meet the
75% rule.
In each case the offsets must be supported
and firestops must be positioned wherever
the vent must pass through a sub-floor, ceil-
ing joist or an attic overhang. The vent pipe
must terminate vertically into a listed type vent
cap and extend a sufficient height through
an approved roof flashing, roof jack or a roof
thimble. At all points listed clearances must
be maintained.
Vent terminations must be located in ac-
cordance with height and proximity rules of
NFPA No. 54. These rules apply to vents at
12" diameter or less and require a minimum
height in accordance with the roof pitch and
a minimum of 8 ft. distance from a vertical
wall or obstruction (see Figure 11, page 11).
A B-type venting system must be connected
to the appliance for venting to the outside of
the building.
The following section is provided as a guide
to a standard B-type vent installation.
Standing codes requirements concerning B-
type vent installations may vary within your
state, province or local codes jurisdiction.
Therefore, it is recommended that you check
with your local building codes for specific
requirements or in absence of local codes,
follow Section 7.0 of the current National Fuel
Gas Code ANSI Z223.1/NFPA 54.
This gas appliance must be vented to the
outdoors only and may not be terminated into
an attic space or into a chimney flue servicing
a solid fuel burning appliance.
This appliance may be vented through a
manufactured chimney system or a masonry
chimney using a B-vent adapter or a chim-
ney liner system if all are listed, inspected
and approved by local codes and/or building
authorities.
The examples shown in Figure 10, are
typical of most B-vent installations and codes
practices.
Example 1: Shows the minimum allowable
system height and lateral offset for a 60° or
greater inclination. Code specifies that offsets
at 60° or greater are considered horizontal
and must follow the 75% rule for lateral to
total vertical system height. Codes also allow
only one offset in the total system when at

Some codes areas allow the use of existing
B-type vent systems if the system is at or
above the recommended diameter of the flue,
in this case 6".
The flue connection must be made using
listed B-type connectors and the existing
system must be code inspected for damage
and proper installation.
It is not recommended that this appliance be
common vented with an existing gas burning
appliance.
Note: Before connecting this appliance to an
existing vent system consult with your local
architect, planner or building official.
WARNING: This appliance
must be properly connected
to a system and must not be
connected to a chimney flue
servicing a separate solid fuel
burning appliance.
CHECKING FOR PROPER VENTING
After completing and checking electrical,
gas and vent connections, follow the lighting
instructions and allow main burner to run
for approximately 5 minutes. Hold a lighted
match or cigarette near the top edge of fire-
place opening and play it along entire length
of opening (see Figure 12). Proper venting
should tend to draw the flame or smoke into
the appliance. Improper venting or escaping
of spillage of burned gas, is indicated when
the match flickers or goes out. Smoke from a
cigarette will also tend to disperse away from
the appliance.
If appliance is found to be improperly vent-
ing, shut it off and notify your installer or a
qualified service agency to inspect the vent-
ing system.
NOTICE: This appliance is
equipped with a vent safety
shutoff switch which will shut
down the appliance in the case
of a venting problem. Do not
bypass the vent safety switch. If
the appliance should shut down,
contact a qualified installer, ser-
vice agency or your gas supplier
to have the vent inspected before
operating.

TROUBLESHOOTING
Note: Before troubleshooting the system, make sure the gas shutoff valve is ON. The two
most common causes of a malfunctioning gas appliance are:
1. Loose wiring connections
2. Construction debris clogging pilot and/or gas control valve filter
OBSERVED PROBLEM
Pilot will not light
Pilot will not stay lit
No gas to burner, although wall
switch and valve are set to the
ON position
Frequent pilot outage
POSSIBLE CAUSE
1. No gas supply or shutoff
valve is OFF
2. Air in gas line
3. Construction debris clog-
ging pilot orifice
4. Low gas pressure
5. Control valve knob is not on
the PILOT position
6. Kinked pilot line
7. Bad valve
8. Vent damper not fully
open
1. Loose wiring on thermopile
to regulator valve. No mil-
livolt current is being sent
back to regulator
2. If valve knob and wall
switch are in the ON posi-
tion, probable defective
regulator valve
3. Vent damper not fully
open
1. Wall switch wires defective
or too long
2. Thermopile not generating
sufficient voltage
1. Pilot flame may be too low,
causing safety pilot to “drop
out”
2. Improper venting or exces-
sive blockage
REMEDY
1. Check to see if you have
gas supply
2. Hold regulator control valve
in the PILOT position for 2
to 3 minutes to purge air. If
you smell gas stop and wait
for a few minutes before
trying to light fireplace
3. Remove debris and dirt,
inspect and clean any other
possible obstructions
4. Contact your gas supplier
5. Refer to section on pilot
lighting
6. Have a qualified technician
replace pilot line
7. Replace regulator valve (see
Accessories, page 31)
8. Open vent damper until fully
locked in OPEN position
1. Check wiring connections.
Refer to wiring diagram
shown in Wall Switch Instal-
lation, page 12
2. Have a qualified technician
replace valve
3. Open vent damper until fully
locked in OPEN position
1. Check electrical connec-
tions
2. See Pilot will not stay lit,
above
1. Clean and adjust pilot flame
for maximum flame im-
pingement on thermopile
2. Have vent system inspect-
ed, including termination
cap. Remove any restric-
tion or obstruction

TROUBLESHOOTING
Continued
OBSERVED PROBLEM
Pilot goes out when wall switch
is ON
Spark ignitor will not light pilot
after repeated triggering of
red button
Fireplace produces a clicking/
ticking noise just after burner
is lit or shut off
POSSIBLE CAUSE
1. Millivolt output on thermo-
pile too high
1. Defective ignitor (no spark
at electrode)
2. Defective pilot or misaligned
electrode at pilot (spark at
electrode)
3. No gas or low gas pres-
sure
4. If using propane/LP gas, no
propane/LP gas in tank
1. Metal expanding while
heating or contracting while
cooling
REMEDY
1. Replace thermopile
1. Check for spark at electrode
and pilot. If no spark and
electrode wire is properly
connected, replace ignitor
2. Using a match, light pilot. If
pilot lights, turn off pilot and
trigger the red button again.
If pilot lights, an improper
gas/air mixture caused the
improper lighting and a
longer purge period is rec-
ommended. If pilot will not
light, check gap at electrode
and pilot. Gap should be
1/8" to have a strong spark.
If okay, replace pilot
3. A) Check remote shut off
valves from fireplace. Usu-
ally there is a valve near the
fireplace and sometimes
there is a valve near the
main. There can be more
than one valve between
fireplace and main
B) Low pressure can be
caused by a variety of situ-
ations such as bent line, or
gas supplier
4. Check propane/LP supply
and contact local propane/
LP supplier
1. This is normal with most
fireplaces. If noise is ex-
cessive, contact qualified
service person
