D. High Altitude Inst allations
U.L. Listed gas appliances are tested and approved 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.
This statement is in compliance with CPSC 16 CFR
Section 1201.5 “Certification and labeling requirements”
which refers to 15 U.S. Code (USC) 2063 stating “…Such
certificate shall accompany the product or shall otherwise
be furnished to any distributor or retailer to whom the
product is delivered.”
Some local building codes require the use of tempered
glass with permanent marking in such locations. Glass
meeting this requirement is available from the factory.
Please contact your dealer or distributor to order .
NOTE: This installation must conform with local codes. In the
absence of local codes you must comply with the National
Fuel Gas Code, ANSI Z223.1-latest edition in the U.S.A.
and the CAN/CGA B149 Installation Codes in Canada.

Getting Started
A. Design and Installation Considerations
Heat & Glo direct vent gas appliances are designed to operate with all combustion air siphoned from outside of the
building and all exhaust gases expelled to the outside. No
additional outside air source is required.
CAUTION
Check building codes prior to installation.
• Installation MUST comply with local, regional, state
and national codes and regulations.
• Consult local building, fire officials or authorities
having jurisdiction about restrictions, installation
inspection, and permits.
When planning an appliance installation, it’s necessary to
determine the following information before installing:
• Where the appliance is to be installed.
• The vent system configuration to be used.
• Gas supply piping.
• Electrical wiring.
• Framing and finishing details.
• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
C. Inspect Appliance and Component s
WARNING
Inspect appliance and components for
damage. Damaged parts may impair safe
operation.
• Do NOT install damaged components.
• Do NOT install incomplete components.
• Do NOT install substitute components.
Report damaged parts to dealer.
• Carefully remove the appliance and components from
the packaging.
• The vent system components and trim doors are shipped
in separate packages.
• The gas logs may be packaged separately and must be
field installed.
• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.
• Read all of the instructions before starting the installation. Follow these instructions carefully during the installation to ensure maximum safety and

B. Constructing the Appliance Chase
A chase is a vertical boxlike structure built to enclose the
gas appliance and/or its vent system. Vertical vents that
run on the outside of a building may be, but are not required to be, installed inside a chase.
or stuffed with unfaced insulation. If the appliance is being
installed on a cement slab, a layer of plywood may be placed
underneath to prevent conducting cold up into the room.
C. Clearances
Construction of the chase may vary with the type of building.
These instructions are not substitutes for the requirements of
local building codes. Local building codes MUST be checked.
Chases should be constructed in the manner of all outside
walls of the home to prevent cold air drafting problems.
The chase should not break the outside building envelope
in any manner.
Walls, ceiling, base plate and cantilever floor of the chase
should be insulated. Vapor and air infiltration barriers should
be installed in the chase as per regional codes for the rest
of the home. Additionally, in regions where cold air infiltration may be an issue, the inside surfaces may be sheetrocked
and taped for maximum air tightness.
To further prevent drafts, the firestops should be caulked
with high temperature caulk to seal gaps. Gas line holes
and other openings should be caulked with high temp caulk
3/4 in.
WARNING
Fire Risk.
Odor Risk.
• Install appliance on hard metal or wood
surfaces extending full width and depth of
appliance.
• Do NOT install appliance directly on
carpeting, vinyl, tile or any combustible
material other than wood.

C. Measuring Standards
Vertical and horizontal measurements listed in the vent
diagrams were made using the following standards.
1. Pipe measurements are shown using the effective length
of pipe (see Figure 5.2).
2. Measurements are made from the appliance outer wrap,
not from the standoffs.
B. Use of Elbows
CAUTION
ALL vent configuration specifications MUST be followed.
• This product is tested and listed to these
specifications.
• Appliance performance will suffer if specifications are
not followed.

Impaired Performance of Appliance
• Overlap pipe slip sections at least 1-1/2 inches.
• Use pilot holes for screws.
• Screws must not exceed one inch long.
• Pipe may separate if not properly joined.
Attaching V ent to the Firebox Assembly
To attach the first pipe section to the collars, slide the male end of
the inner vent of the pipe section over the inner collar on the firebox
assembly. At the same time, slide the outer flue over the outer
collar on the appliance. Push the pipe section into the appliance
collar until all the lances (see Figure 8.1) have snapped in place.
Tug slightly on the section to confirm it has completely locked into
place.
Assembling Pipe Sections
Insert the inner flue of section A into the flared inner flue of section B.
Start the outer flue of section A over the outer flue of section B (see
Figure 8.2). Note: The end of the pipe sections with the lances/tabs
on it will face towards the appliance.
Once both inner and outer flues
are started, press section A onto
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

Assembling Minimum Installations (MI) Sections
MI sections are non-unitized so that they can be cut to a
certain length. Cut these sections to length from the nonexpanded end (see Figure 8.5).
They can then be attached by first connecting the expanded
end of the MI inner flue with the inner pipe from the adjacent
pipe section and securing with three screws. The expanded
portion of the MI inner flue must overlap completely with
the unexpanded end of the adjacent pipe section.
The outer flue can then be inserted into the adjacent outer
flue expanded end and attached to the next pipe section
with three screws. The other end of the MI pipe section
can then be attached by fitting another pipe section to it
and snapping it together, as normal.
Assembling DVP-12A Slip Sections
The outer flue of the slip section should slide over the outer
flue of the pipe section and into (inner flue) the last pipe
section (see Figure 8.6) .
Figure 8.5
Slide together to the desired length, making sure that a
1-1/2 inch outer flue overlap is maintained between the
pipe section and slip section.
The pipe and slip section need to be secured by driving
two screws through the overlapping portions of the outer
flues using the pilot holes (see Figure 8.7).
This will secure the slip section to the desired length and
prevent it from separating. The slip section can then be
attached to the next pipe section.
If the slip section is too long, the inner and outer flues of
the slip section can be cut to the desired length.

C. Af ter Appliance is Lit
Initial Break-in Procedure
When you light the appliance, you may notice that it produces heat which does have an associated odor or smell.
If you feel this odor is excessive it may require the initial
three to four hour continuous burn on high followed by a
second burn up to 12 hours to fully drive off any odor from
paint and lubricants used in the manufacturing process.
Condensation of the glass is normal.
NOTE: The appliance should be run three to four hours
on the initial start-up. T urn it of f and let it cool completely.
Remove and clean the glass. Replace the glass and run
the appliance for an additional 12 hours. This will help to
cure the products used in the paint and logs.
During this break-in period it is recommended that some windows in the house be opened for air circulation. This will help
avoid setting off smoke detectors, and help eliminate any
odors associated with the appliance’s initial burning.
CAUTION
• Prevent accidental appliance operation when not
attended.
• Unplug or remove batteries from remote control if
absent or if appliance will not be used for an extended
period of time.
• Property damage possible from elevated temperatures.
CAUTION
Smoke and odors released during initial operation.
• Open windows for air circulation.
• Leave room during initial operation.
• Smoke may set off smoke detectors.
Smoke and odors may be irritating to sensitive
individuals.
WARNING
Fire Risk.
High Temperatures.
Keep combustible household items away from appliance.
Do NOT obstruct combustion and ventilation air.
• Do NOT place combustible items on top of or in front
of appliance.
• Keep furniture, draperies away from appliance.
D. Frequently Asked Questions
ISSUE SOLUTIONS
Condensation on the glass
Blue flames
Odor from appliance
Thi s is a result of gas combustion and temperature variations. As the appliance
warms, this condensation will disappear.
Thi s is a result of normal operation and the flames will begin to yellow as the
appliance is allowed to burn for 20 to 40 minutes.
When first operated, this appliance may release an odor for the first several hours.
Thi s is caused by the curing of the paint and the burning off of any oi ls remaining
from manufacturing. Odor may also be released from finishing materials and
adhesives used around the fireplace.
WARNING
Fire Hazard.
Keep combustible materials, gasoline
and other flammable vapors and liquids
clear of appliance.
• Do NOT store flammable materials in the appliance’s
vicinity.
• Do NOT use gasoline, lantern fuel, kerosene, charcoal
lighter fluid or similar liquids in this appliance.
• Combustible materials may ignite.
Film on the glass
Meta llic noise
Is it normal to see the pi lot flame
bur n co nt inually?
Thi s is a normal result of the curing process of the paint and logs. Glass should be
cleaned within 3 to 4 hours of initial burni ng to remove deposits left by oils from the
manufacturing process. A non-abrasive cleaner such as gas fireplace glass cleane r
may be necessary. See your dealer.
Noise is caused by metal expanding and contracting as it heats up and cools down,
similar to the sound produced by a furnace or heating duct. This noise does not affect
the operation or longevity of the fireplace.
In an Intellifire ignition system it is normal to see the pilot flame, but it should turn off
when ON/OFF is turned off. In a standing pilot system the pilot will always stay on.
