lung disease or anemia, those under the influ-
ence of alcohol and those at high altitudes.
Propane/LP gas and natural gas are both
odorless. An odor-making agent is added
to each of these gases. The odor helps you
detect a gas leak. However, the odor added
tothese gases canfade.Gas may bepresent
even though no odor exists.
Make certain you read and understand all
warnings. Keep this manual for reference. It

CAUTION: Do not connect
appliance before pressure test-
ing gas piping. Damage to gas
valve may result and an unsafe
condition may be caused.
Theappliance and it’sindividual shutoff valve
mustbe disconnected fromgas supply piping
system during any pressure testing of that
system at test pressures in excess of 1/2
psig (3.5 kPa).
The appliance must be isolated from the gas
supply piping system by closing its individual
manualshutoffvalveduringanypressuretesting
ofthegassupplypipingsystemattestpressures
equal to or less than 1/2 psig (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 arerecommendedwhere
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 providea 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
locationforyour appliance, you must takeinto
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
orroofrafterswill make installation easier.
Figure 1 shows a plan view of a few com-
mon locations.

FRAMING
1. Frame appliance enclosure as illustrated
in Figures 7 and 8.
Note: If a wall covering is used to line the
enclosure, then all measurements must
be from the surface of the covering.
2. Place the appliance into the framing and
secure it.
Note: If appliance is to be raised above
floor level, a platform must be built to
support the appliance.
3. Install the supply line to the appliance
using a 1/2" NPT black iron gas line ter-
minating 2 5/16" above the bottom of the
appliance. The gas line must be installed
throughthe lower left sideaccess point or
alternate access hole in the bottom of the
appliance (see Figure 19, page 13).
4. Repack insulation around the gas line to
coverany remaining openings in thecon-
duitsleeve.Prepare the incoming gas line
with teflon tape or pipe joint compound
and hook-up incoming gas line to the
flexible gas line.
Note: If 1/2" NPT black iron pipe does not
mate with fitting at the end of flexible gas
line, remove fitting and replace with a 37°
flare 3/4"-12, 1/2" NPT (female) fitting.
WARNING: When finishing
appliance, do not overlap com-
bustible material onto the black
front face. Brick, tile or other
noncombustible materials may
be applied to the face provided
that any gap is between the
material used and the face is
caulked with a noncombustible
caulking.

INSTALLING TRANSITION PIPE AND
STARTER COLLAR
The transition pipe and starter collar shown
in Figure 9 are supplied with the fireplace,
unattached and ready for installation. Re-
move starter collar and set aside. Slide
transition pipe over vent collar and attach
with a minimum of three screws. Replace
starter collar over transition pipe and attach
using four screws located on leg stands (five
used on model M42). To install B-vent piping,
slide the first piece of B-vent over transition
pipe and attach with either a minimum of two
screws or other means approved by the vent
manufacturer. Figure 9 - Installing Transition Pipe and

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-
tediftheydonotexceed45° of inclination.The
totallengthsofthetwo offsetsarenotrequired
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
mustterminateverticallyintoa 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
heightin accordance withthe roof pitchand a
minimum of 8 ft. distance from a vertical wall
or obstruction (see Figure 11, page 10).
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,
followSection 7.0 of thecurrentNational Fuel
Gas Code ANSI Z223.1/NFPA 54.
This gas appliance must be vented to the
outdoorsonly and maynot be terminated into
anattic space orintoa chimney flueservicing
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, page 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
greaterinclination.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
abovetherecommended diameter of theflue,
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.
