D. High Altitude Installations  
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.  
NOT INTENDED FOR USEASAPRIMARY HEAT SOURCE.  
This appliance is tested and approved as either supplemen-  
tal room heat or as a decorative appliance. It should not be  
factored as primary heat in residential heating calculations.  
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.  
B. Glass Specifications  
Hearth & Home Technologies appliances manufactured  
with tempered glass may be installed in hazardous  
locations such as bathtub enclosures as defined by the  
Consumer Product Safety Commission (CPSC). The  
tempered glass has been tested and certified to the  
requirements of ANSI Z97.1 and CPSC 16 CFR 1202  
(Safety Glazing Certification Council SGCC# 1595 and  
1597. Architectural Testing, Inc. Reports 02-31919.01 and  
02-31917.01).  
If installing this appliance at an elevation above 4500 feet  
(in Canada), check with local authorities.  
WARNING  
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.”  
Do NOT use this appliance if any part has been under  
water. Immediately call a qualified service technician to  
inspect the appliance and to replace any part of the control  
system and any gas control which has been under water.  
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.

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.  
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 re-  
quired to be, installed inside a chase.  
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.  
WARNING  
Fire Risk.  
Odor Risk.  
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.  
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.  
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 infiltra-  
tion may be an issue, the inside surfaces may be sheetrocked  
and taped for maximum air tightness.  
WARNING  
Fire Risk.  
Construct chase to all clearance  
specifications in manual.  
Locate and install appliance to all  
clearance specifications in manual  
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

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 non-  
expanded 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.  
Figure 8.5  
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) .  
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.  
Figure 8.6 Slip Section Pilot Holes  
If the slip section is too long, the inner and outer flues of  
the slip section can be cut to the desired length.

Securing the Vent Sections  
Vertical Sections  
Vertical sections of pipe must be supported every 8 feet  
after the 25 foot maximum unsupported rise. The vent  
support or plumber’s strap (spaced 120° apart) may be  
used to do this (see Figure 8.8).  
Horizontal Sections  
Horizontal sections of vent must be supported every 5 feet  
with a vent support or plumber’s strap.  
Figure 8.8 Securing Vertical Pipe Sections  
Figure 8.9 Securing Horizontal Pipe Sections  
B. Disassembly of Vent Sections  
To disassemble any two pieces of pipe, rotate either section  
(see Figure 8.10), so that the seams on both pipe sections  
are aligned (see Figure 8.11). They can then be carefully  
pulled apart.  
WARNING

C. After Appliance is Lit  
Initial Break-in Procedure  
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.  
When you light the appliance, you may notice that it pro-  
duces 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.  
Property damage possible from elevated temperatures.  
NOTE: The appliance should be run three to four hours  
on the initial start-up. Turn it off 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.  
CAUTION  
Smoke and odors released during initial operation.  
Open windows for air circulation.  
Leave room during initial operation.  
Smoke may set off smoke detectors.  
During this break-in period it is recommended that some win-  
dows 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.  
Smoke and odors may be irritating to sensitive  
individuals.

D. Frequently Asked Questions  
ISSUE  
SOLUTIONS  
This is a result of gas combustion and temperature variations. As the appliance  
warms, this condensation will disappear.  
Condensation on the glass  
Blue flames  
This 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.  
This is caused by the curing of the paint and the burning off of any oils remaining  
from manufacturing. Odor may also be released from finishing materials and  
adhesives used around the fireplace.  
Odor from appliance  
Film on the glass  
Metallic noise  
This is a normal result of the curing process of the paint and logs. Glass should be  
cleaned within 3 to 4 hours of initial burning to remove deposits left by oils from the  
manufacturing process. A non-abrasive cleaner such as gas fireplace glass cleaner  
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.  
Is it normal to see the pilot flame  
burn continually?  
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.
