B. Limited Lifetime Warranty  
Hearth & Home Technologies Inc.  
LIMITED LIFETIME WARRANTY  
Hearth & Home Technologies Inc., on behalf of its hearth brands (”HHT”), extends the following warranty for  
HHT gas, wood, pellet, coal and electric hearth appliances that are purchased from an HHT authorized dealer.  
WARRANTY COVERAGE:  
HHT warrants to the original owner of the HHT appliance at the site of installation, and to any transferee taking ownership  
of the appliance at the site of installation within two years following the date of original purchase, that the HHT appliance  
will be free from defects in materials and workmanship at the time of manufacture. After installation, if covered compo-  
nents manufactured by HHT are found to be defective in materials or workmanship during the applicable warranty period,  
HHT will, at its option, repair or replace the covered components. HHT, at its own discretion, may fully discharge all of its  
obligations under such warranties by replacing the product itself or refunding the verified purchase price of the product  
itself. The maximum amount recoverable under this warranty is limited to the purchase price of the product. This warranty  
is subject to conditions, exclusions and limitations as described below.  
WARRANTY PERIOD:  
Warranty coverage begins on the date of original purchase. In the case of new home construction, warranty coverage  
begins on the date of first occupancy of the dwelling or six months after the sale of the product by an independent,  
authorized HHT dealer/ distributor, whichever occurs earlier. The warranty shall commence no later than 24 months  
following the date of product shipment from HHT, regardless of the installation or occupancy date. The warranty period for  
parts and labor for covered components is produced in the following table.  
The term “Limited Lifetime” in the table below is defined as: 20 years from the beginning date of warranty coverage for  
gas appliances, and 10 years from the beginning date of warranty coverage for wood, pellet, and coal appliances. These  
time periods reflect the minimum expected useful lives of the designated components under normal operating conditions.

L. After Fireplace is Lit  
Initial Break-in Procedure  
•
The fireplace should be run three to four hours  
continuously on high.  
•
•
•
•
Turn the fireplace off and allow it to completely cool.  
Remove fixed glass assembly. See Section 15.D.  
Clean fixed glass assembly. See Section 3.  
Replace the fixed glass assembly and run continuously  
on high an additional 12 hours.  
This cures the materials used to manufacture the fire-  
place.  
NOTICE! Open windows for air circulation during fireplace  
break-in.  
• Some people may be sensitive to smoke and  
odors.  
• Smoke detectors may activate.  
M. Frequently Asked Questions  
ISSUE  
SOLUTIONS  
Condensation on the glass  
This is a result of gas combustion and temperature variations. As the appliance warms, this  
condensation will disappear.  
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.  
Odor from appliance  
When first operated, this appliance may release an odor for the first several hours. This is caused  
by the curing of materials from manufacturing. Odor may also be released from finishing materials  
and adhesives used near the appliance. These circumstances may require additional curing  
related to the installation environment.  
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. A non-abrasive cleaner such as gas appliance 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 appliance.  
Is it normal to see the pilot  
flame burn continually?  
In an IntelliFire Plus™ ignition system (IPI), the pilot flame should turn off when appliance is  
turned off. Some optional control systems available with IPI models may allow pilot flame to  
remain lit. In a standing pilot system the pilot will always stay on.

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.  
B. Construct the Appliance Chase  
A chase is a vertical box-like structure built to enclose the  
gas appliance and/or its vent system. In cooler climates  
the vent should enclosed inside the chase.  
NOTICE: Treatment of ceiling firestops and wall shield  
firestops and construction of the chase may vary with the  
type of building. These instructions are not substitutes for the  
requirements of local building codes. Therefore, you MUST  
check local building codes to determine the requirements  
to these steps.  
To further prevent drafts, the wall shield and ceiling fire-  
stops should be caulked with caulk with a minimum of 300ºF  
continuous exposure rating to seal gaps. Gas line holes and  
other openings should be caulked with caulk with a mini-  
mum of 300ºF continuous exposure rating or stuffed with un-  
faced insulation. If the appliance is being installed on a ce-  
ment slab, a layer of plywood may be placed underneath  
to prevent conducting cold up into the room.  
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.

C. Use of Elbows  
Diagonal runs have both vertical and horizontal vent as-  
pects when calculating the effects. Use the rise for the  
vertical aspect and the run for the horizontal aspect (see  
Figure 7.1).  
DVP Pipe  
(see chart)  
Two 45º elbows may be used in place of one 90º elbow.  
On 45º runs, one foot of diagonal is equal to 8-1/2 in. (216  
mm) horizontal run and 8-1/2 in. (216 mm) vertical run. A  
length of straight pipe is allowed between two 45º elbows  
(see Figure 7.1).

D. Measuring Standards  
Vertical and horizontal measurements listed in the vent  
diagrams were made using the following standards.  
SLP Pipe  
(see chart)  
•
Pipe measurements are shown using the effective length  
of pipe (see Figure 7.2).  
Figure 7.2 Pipe Effective Length  
•
Horizontal terminations are measured to the outside  
mounting surface (flange of termination cap) (see  
Figure 6.4.).  
•
•
Vertical terminations are measured to bottom of  
termination cap.  
Horizontal pipe installed level with no rise.

E. Vent Diagrams  
Note: The NEVO series appliances can adapt to  
SLP series vent pipe when venting off the top of  
the appliance. You must use a DVP-SLP24 adapter  
which can only be attached to the appliance starting  
collar.  
To replace the first starter elbow with two 45° elbows,  
refer to Figure 7.4. All other 90° elbows can be replaced  
with two 45° elbows.  
General Rules:  
When looking at horizontal termination diagrams, the  
adapter is not counted as part of the minimum vertical  
•
•
•
SUBTRACT 3 ft. from the total H measurement for each  
90° elbow installed horizontally.  
SUBTRACT 1-1/2 ft. from the total H measurement for  
each 45° elbow installed horizontally.  
A maximum of three 90° elbows (or six 45° elbows)  
may be used in any vent configuration. Some elbows  
may be installed horizontally. See Figure 7.8.  
Elbows may be placed back to back anywhere in the  
system as long as the first 90° elbow is a starter elbow  
except as shown in Figure 7.4.  
(V min.) requirements.

Whether horizontal or vertical termination, the adapter is  
counted as part of the maximum vertical limitations.  
All venting rules for the vent run must still be followed.  
HORIZONTAL EXAMPLE  
•
•
•
•
When penetrating a combustible wall, a wall shield  
firestop must be installed.  
When penetrating a combustible ceiling, a ceiling  
firestop must be installed.  
Horizontal runs of vent do not require vertical rise;  
horizontal runs may be level.

Vent Clearances and Framing  
8
A. Pipe Clearances to Combustibles  
WARNING! Risk of Fire! Maintain air space clearance to  
vent. DO NOT pack insulation or other combustibles:  
B. Wall Penetration Framing  
Combustible Wall Penetration  
Whenever a combustible wall is penetrated, you must  
frame a hole for the wall shield firestop(s). The wall shield  
firestop maintains minimum clearances and prevents cold  
air infiltration.  
•
•
•
Between ceiling firestops  
Between wall shield firestops  
Around vent system  
Failure to keep insulation or other material away from  
vent pipe may cause over heating and fire.  
•
•
•
The opening must be framed on all four sides using the  
same size framing materials as those used in the wall  
construction.  
SLP pipe -Awall shield firestop must be placed on each  
side of an interior wall. A minimum 1 1/2 in. (38 mm)  
overlap of attached heat shields must be maintained.  
DVP pipe - A wall shield firestop is required on one side  
only on interior walls. If your local inspector requires a  
wall shield firestop on both sides, then both wall shield  
firestops must have a heat shield attached to them.  
See Section 10.L. for information for regarding the  
installation of a horizontal termination cap.  
Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).  
• DVP heat shield - designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184  
mm) thick.  
•
If wall thickness is less than 4 in. the existing heat shields must be field trimmed.  
If wall thickness is greater than 7-1/4 in. an extended heat shield will be required.  
• SLP heat shield - designed to be used on a wall 4-3/8 in. to 7-5/8 in. (111 mm to 194  
mm thick).  
•
If wall thickness is less than 4-3/8 the existing heat shields must be field trimmed.  
If wall thickness is greater than 7-5/8 in. an extended heat shield will be required.

• DO NOT remove the heat shields attached to the  
wall shield firestop and the horizontal termination  
cap.  
• Heat shields must overlap 1-1/2 in. (38 mm) mini-  
mum.  
Termination Cap  
There are two sections of the heat shield. One section  
is factory-attached to the wall shield firestop. The other  
section is factory-attached to the cap. See Figure 10.20.  
If the wall thickness does not allow the required 1-1/2 in.  
(38 mm) heat shield overlap when installed, an extended  
heat shield must be used.  
•
If the wall thickness is less than 4 in./102 mm (DVP) or  
4-3/8 in./ 111 mm (SLP), the heat shields on the cap and  
wall shield firestop must be trimmed. A minimum 1-1/2  
in. (38 mm) overlap MUST be maintained.  
Use an extended heat shield if the finished wall thickness  
is greater than 7-1/4 in. (184 mm).  
The extended heat shield may need to be cut to length  
maintaining sufficient length for a 1-1/2 in. (38 mm)  
overlap between heat shields.

Verify that ceramic insulator around the flame sensing rod is not  
cracked, damaged, or loose. Verify connection from flame sensing  
rod to white sensor wire. Polish flame sensing rod with fine steel  
wool to remove any contaminants that may have accumulated on  
flame sensing rod. Verify continuity with a multimeter with ohms  
set at lowest range. Replace pilot if any damage is detected.  
E. Module.  
Turn ON/OFF rocker switch or wall switch to OFF position.  
Remove ignitor wire “I” from module. Place ON/OFF rocker switch
