INSTALLATION
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. This
replace must be installed in an unconned
space with a minimum of 50 cubic feet per
1,000 BTUs of gas output. Therefore 36”
models require 2,650 cubic feet, 42” models
require 3,100 cubic feet.. If the space you
wish to install the replace does not meet
these requirements NFPA 54 details several
actions that may be taken.
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,
nished wall.
Corner installations make use of space
that may not normally be used and provides
a wider and more efcient 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.
CAUTION: Do not connect
appliance before pressure test-
ing gas piping. Damage to gas
valve may result and an unsafe
condition may be caused.
SELECTING LOCATION
To determine the safest and most efcient
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.
Flush installations are recommended where

VENTING INSTALLATION
total vertical system height. Codes also allow
only one offset in the total system when at
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 restops must be positioned wherever
the vent must pass through a sub-oor, ceil-
ing joist or an attic overhang. The vent pipe
must terminate vertically into a listed type vent
cap and extend a sufcient height through
an approved roof ashing, roof jack or a roof
thimble (38FST recommended). 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 installation standards of its product. Third
party products must be installed to their speci-
ed standards.
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 specic
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 ue
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 species that offsets
at 60° or greater are considered horizontal
and must follow the 75% rule for lateral to

Some codes areas allow the use of existing
B-type vent systems if the system is at or
above the recommended diameter of the ue,
in this case 6".
The ue 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 ofcial.
WARNING: This appliance
must be properly connected
to a system and must not be
connected to a chimney ue
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 re-
place opening and play it along entire length
of opening (see Figure 12). Proper venting
should tend to draw the ame or smoke into
the appliance. Improper venting or escaping
of spillage of burned gas, is indicated when
the match ickers 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
qualied 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 qualied installer, ser-
vice agency or your gas supplier
to have the vent inspected before
operating.

Note: The receiver and hand-held remote
control kit must be purchased separately (see
Accessories, page 31). Follow installation
instructions included with the remote control.
Check pilot ame pattern and burner ame

PILOT ASSEMBLY
The pilot assembly is factory preset for the
proper ame height. Alterations may have
occurred during shipping and handling. The
pilot is located on the back right hand side
of the burner.
The height of the thermopile must be 3/8" to
1/2" above the pilot ame. The ame from
the pilot burner must extend beyond the
thermopile.
If your pilot assembly does not meet these
requirements:
• Turn adjustment screw marked pilot clock-
wise to decrease or counterclockwise to in-
crease the ame to proper size (see Figure
36, page 19). Do not remove adjustment
screw.
