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).
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.
A. Appliance Certification
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.
NOTINTENDED FOR USEASAPRIMARYHEATSOURCE.
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.
Listing and Code Approvals
D. High Altitude Installations
U.L.Listedgasappliances are tested andapprovedwithout
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
changingthe existingburner orificeto asmaller 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
between2000and4500feetin Canada. If the heatingvalue
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.

erate with all combustion air siphoned from outside of the
buildingand allexhaust gasesexpelled tothe outside.No
additionaloutside air source is required.
Getting Started
C. Inspect Appliance and Components
2
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,

Provide adequate clearance:
• Around air openings
• To combustibles
• For service access
Locate appliance away from traffic areas.
A. Selecting Appliance Location
When selecting a location for your appliance it is important
toconsiderthe required clearancestowalls (see Figure3.1).

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.
Construction of the chase may vary with the type of building.
Theseinstructions are not substitutes for the requirements of
localbuildingcodes.LocalbuildingcodesMUSTbechecked.
Chasesshould beconstructed in the manner of alloutside
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
shouldbeinsulated.Vaporandairinfiltrationbarriersshould
be installed in the chase as per regional codes for the rest
of the home. Additionally, in regions where cold air infiltra-
tionmaybeanissue,theinsidesurfacesmaybesheetrocked
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
andotheropenings should becaulkedwith high tempcaulk

CAUTION
Sharp Edges
• Wear protective gloves

• Place the appliance into position.
• Level the appliance from side to side and front to back.
• Shim the appliance with noncombustible material, such
as sheet metal, as necessary.
• Remove two side screws from each nailing tab (see
Figure 7.2) and refasten nailing tabs to the appliance.
Note: Return bend on nailing tab faces back of unit.
• Keep nailing tabs flush with the framing.
• Secure the appliance to the framing by using nails or screws
through the nailing tabs.
• Holes are also provided in appliance bottom to secure
appliance to floor.
WARNING

Assembling Pipe Sections
Inserttheinnerflue of sectionAintotheflared inner flue ofsectionB.
Start the outer flue of sectionAover the outer flue of section B (see
Figure 8.2).Note: The end ofthe pipe sectionswiththe lances/tabs
on it will face towards the appliance.
Onceboth innerand outerflues
arestarted,press sectionAonto
section B firmly until all lances
havesnappedintoplace. 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 section A to confirm
it has completely locked into
place.
For90° and45° elbowsthat are
changingtheventdirection from
horizontalto vertical,one screw
minimum should be put in the
outerflueatthehorizontalelbow
joint to prevent the elbow from
rotating.
Attaching Vent to the Firebox Assembly
To attach the first pipe section to the collars, slide the male end of
theinner vent of the pipesection overthe inner collar on thefirebox
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.

CORRECT INCORRECT
Fire Risk
Exhaust Fumes Risk
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.
WARNING

Heat & Glo • Crescent II • 2083-902 Rev. G • 9/0520
Assembling DVP-12A Slip Sections
Theouter flue ofthe slipsection should slideover 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.
If the slip section is too long, the inner and outer flues of
the slip section can be cut to the desired length.
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).
Theycanthenbeattachedbyfirstconnectingtheexpanded
endoftheMIinnerflue with the innerpipe fromtheadjacent
pipesectionandsecuringwith three screws.Theexpanded
portion of the MI inner flue must overlap completely with
the unexpanded end of the adjacent pipe section.
Theouter flue can then be inserted intothe adjacentouter
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.
