D. High Altitude Installations
U.L.Listed gasappliances aretested andapproved without
requiring changes for elevations from 0 to 2000 feet in the
U.S.A. and Canada.
When installing this appliance at an elevation above 2000
feet, it may be necessary to decrease the input rating by
changing the existing burner orifice to a smaller size. Input
rate should be reduced by 4% for each 1000 feet above
a 2000 foot elevation in the U.S.A., or 10% for elevations
between 2000 and 4500 feet in Canada. If the heating
value of the gas has been reduced, these rules do not
apply. To identify the proper orifice size, check with the
local gas utility.
If installing this appliance at an elevation above 4500 feet
(in Canada), check with local authorities.

A. Pipe Clearances to Combustibles
Vent Clearances and Framing
6
Combustible Wall Penetration
Frame a hole in a combustible wall for an interior wall
shield firestop, (Figure 6.2) whenever a wall is penetrated.
Use same size framing materials as those used in the wall
construction. The wall shield firestop maintains minimum
clearances and prevents cold air infiltration.
Non-Combustible Wall Penetration
If the hole being penetrated is surrounded by noncombus-
tible materials such as concrete, a hole with diameter one
inch greater than the pipe is acceptable.
Fire Risk.
Explosion Risk.
Maintain vent clearance to combustibles as
specified.
WARNING
• Do not pack air space with insulation or
other materials.
Failure to keep insulation or other materials
away from vent pipe may cause fire.

C. Vertical Penetration Framing
Installing the Ceiling Firestop
• Frame an opening 10 inches by 10
inches whenever the vent system
penetrates a ceiling/floor (see Figure
6.3).
• Frame the area with the same sized
lumber as used in ceiling/floor joist.
• When installing a top vent vertical ter-
mination appliance the hole should be
directlyabove theappliance, unlessthe
flue is offset.
• Donotpack insulationaround thevent.
Insulation must be kept away from the
pipe.

WARNING
Fire Hazard
Keep loose materials or blown
insulation from touching the
vent pipe.
Installing Attic Shield
Note: An additional ceiling firestop is not
required if attic shield is used.
• Frame opening for attic shield.
• Attic shield may be installed above or
below ceiling (see Figure 6.4).
• Secure with three fasteners on each
side.
• Fold tabs at top of attic shield in toward
vent pipe. Tabs must keep vent pipe
centered within shield.
• Fieldconstruct additionalshield heightif
insulation is deeper than height of attic
shield.
Figure 6.4 Installing the Attic Shield
• National building codes recommend us-
ing attic shield to keep loose materials/
blown insulation from contacting vent.
• Hearth & Home Technologies requires
the use of an attic shield.

CAUTION
Sharp Edges
• Wear protective gloves
and safety glasses dur-
ing installation.
The diagram shows how to properly position, level, and
secure the appliance (see Figure 7.1). Nailing tabs are pro-
vided to secure the appliance to the framing members.
• Place the appliance into position.
• Level the appliance from side to side and front to
back.
• Shimtheappliance asnecessary. Itisacceptable touse
wood shims.
• Bend out nailing tabs on each side.
• Keep nailing tabs flush with the framing.
• Secure the appliance to the framing by using nails or
screwsthrough thenailingtabs.Holesare providedinthe
basepan (inside the hearth) for securing to the floor.
A. Securing and Leveling the Appliance
WARNING
Fire Risk.
•Prevent contact with sagging, loose
insulation.
•Do NOT install against combustible
materials such as exposed insulation,
plastic and insulation backer.
WARNING
Fire Risk.
• ALWAYS maintain specified
clearances around the appliance.
• Do NOT notch into the framing around the appliance spacers.
Failure to keep insulation, framing or other material away
from the appliance may cause fire.

Assembling Pipe Sections
Insert the inner flue of section A into the flared inner flue of
section B.
Start the outer flue of sectionAover the outer flue of section B (see
Figure 8.2).Note: Theend ofthe pipesectionswith thelances/tabs
on it will face towards the appliance.
Attaching Vent to the Firebox Assembly
To attach the first pipe section to the collars, slide the male end of
theinnervent ofthepipe sectionoverthe innercollaron the firebox
assembly.Atthesame time,slide theouterflueoverthe outercollar
onthe appliance.Push thepipe sectionintotheappliancecollaruntil
all the lances (see Figure 8.1) have snapped in place. Tug slightly
on the section to confirm it has completely locked into place.

INCORRECT
CORRECT
Once both inner and outer flues
are started, press sectionAonto
section B firmly until all lances
have snapped into place. Check
to make sure they have snapped
together (see Figure 8.3) and
the seams are not aligned (see
Figure 8.4). Tug slightly on sec-
tionAto confirmit hascompletely
lockedintoplace. Itis acceptable
to use screws no longer than 1
inch to hold outer pipe sections
together. If predrilling holes, do
NOT penetrate inner pipe.
For 90° and 45° elbows that are changing the vent direction from
horizontaltovertical, onescrew minimumshould beputin theouter
flue at the horizontal elbow joint to prevent the elbow from rotating.
Use screws no longer than 1 inch. If predrilling screw holes, do
NOT penetrate inner pipe.
