INSTALLATION
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
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.
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 the gas 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
manual shutoff valve during any pressure
testing of the gas supply piping system at
test pressures 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.
SELECTING LOCATION
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.

A B-type venting system must be connected to
appliance for venting to outside of 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 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.

www.desatech.com
108794-01F 9
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 9 are typi-
cal 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
total vertical system height. Codes also al-
lows 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 the
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.

VENTING INSTALLATION
Continued
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. At all points the 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 feet distance from a vertical wall
or obstruction (see Figure 10, page 10).
If venting horizontally through a side wall be-
comes necessary, a listed thimble approved
for use with B-type vent must be used. Check
with your local codes before venting through
a side wall.
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.
The ue connection must be made using
listed B-type connectors and the existing
system must be code inspected for damage
and proper installation.

VENTING INSTALLATION
Continued
It is not recommended that this appliance be
common vented with an existing gas burning
appliance. However, if it becomes necessary
to common vent this appliance, the venting
system must be sized and congured in ac-
cordance with the common venting guides
Appendix G of the current National Fuel Gas
Code NFPA No. 54/ANSI Z223.1.
Note: Before connecting this appliance to an
existing vent system or a common venting
system consult with your local architect, plan-
ner, 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 lighting
instructions and allow main burner to run
for approximately 5 minutes. Hold a lighted
match or cigarette near top edge of replace
opening and play it along entire length of
the 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 the appliance is found to be improperly
venting, shut it off and notify your installer
or a qualied service agency to inspect the
venting 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
