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.

5. Module Reset  
I. Control Module Operation  
This module may lock-out under certain conditions.  
When this occurs, the appliance will not ignite or  
respond to commands. The module will go into lock-out  
mode by emitting three audible beeps, then continuously  
displaying a RED/GREEN error code at its status  
indicator LED.  
1. The control module has an ON/OFF/REMOTE selector  
switch that must be set. See Figure 2.3.  
OFF Position: Appliance will ignore all power inputs and  
will not respond to any commands from a wall switch or  
remote. The unit should be in the OFF position during  
installation, service, battery installation, fuel conversion,  
and in the event that the control goes into LOCK-OUT  
mode as a result of an error code.  
•
Check battery tray. Remove batteries if installed.  
Batteries should only be installed for use during power  
outages. See Section H.  
ON Position: Appliance will ignite and run continuously  
in the HI flame setting, with no adjustment in flame  
output. This mode of operation is primarily used for  
initial installation or power outage operation with battery  
backup.  
•
•
•
Locate the module selector switch. (See Figure 2.3).  
Set the module selector switch to the OFF position.  
Wait five (5) minutes to allow possible accumulated gas  
to clear.  
REMOTE Position: Appliance will initiate commands  
from an optional wired wall switch and/or the wireless  
remote (RC300).  
•
Set the module selector switch to ON or REMOTE  
position.  
•
Start the appliance.  
2. If using a wired wall switch with the module in REMOTE  
mode, the flame output can be adjusted with the HI/LO  
selector switch on the module. See Figure 2.3. Note  
that the flame HI/LO selector switch will become inactive  
once an optional remote control (RC200/RC300) is  
programmed to the control module. Note that the control  
module will always ignite the fireplace on HI and remain  
so for the initial 10 seconds of operation. If the HI/LO  
is switched to the LO position, the flame output will  
automatically drop to the lowest setting after the flame  
has been established for 10 sec. After this 10 second  
period, the flame can be adjusted from HI to LO with  
the switch.  
WARNING! Risk of Explosion! DO NOT reset the mod-  
ule more than one time within a five minute time period.  
Gas may accumulate in firebox. Call a qualified service  
technician.

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 14.H.  
• 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 fire-  
place break-in.  
• Some people may be sensitive to smoke and odors.  
• Smoke detectors may activate.  
M. 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  
This is a result of normal operation and the flames will begin to yellow as the appliance is al-  
lowed to burn for 20 to 40 minutes.  
Blue flames  
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 appliance.  
Odor from appliance  
Film on the glass  
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 appliance.  
Metallic noise  
In an intermittent pilot 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.  
Is it normal to see the pilot flame burn  
continually?

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. Constructing 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 be 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 minimum of 300ºF continuous exposure rating or stuffed  
with unfaced insulation. If the appliance is being installed  
on a cement surface, 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 out-  
side walls of the home to prevent cold air drafting prob-  
lems. The chase should not break the outside building  
envelope in any manner.  
COMBUSTIBLE FLOORING MAY BE INSTALLED

A. Approved Pipe  
This appliance is approved for use with Hearth & Home  
Technologies DVP or SLP venting systems. Refer to Sec-  
tion 16B for vent component information.  
DO NOT mix pipe, fittings or joining methods from differ-  
ent manufacturers.  
Vertical  
The pipe is tested to be run inside an enclosed wall.  
There is no requirement for inspection openings at each  
joint within the wall.  
8-1/2 in.  
WARNING! Risk of Fire or Asphyxiation. This appli-  
ance requires a separate vent. DO NOT vent to a pipe  
serving a separate solid fuel burning appliance.

Description  
D. Measuring Standards  
First section (closest to appliance) of vertical length  
V1  
Vertical and horizontal measurements listed in the vent  
diagrams were made using the following standards.  
Second section of vertical length  
V2  
H1  
H2  
• Pipe measurements are shown using the effective length  
of pipe (see Figure 7.2).  
First section (closest to appliance) of horizontal length  
Subsequent sections of horizontal length  
• Horizontal terminations are measured to the outside  
mounting surface (flange of termination cap) (see Figure  
6.3).  
C. Use of Elbows  
• Vertical terminations are measured to bottom of  
termination cap.  
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).  
• Horizontal pipe installed level with no rise.  
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).

E. Vent Diagrams  
Top Vent - Horizontal Termination  
Note: The CD series fireplaces can adapt to SLP series  
vent pipe, if desired.  
When venting off the top of the unit, use a DVP-2SL adapter  
and a minimum 48 inch vertical section of SLP series vent  
pipe.  
4 ft min.  
(1.22 m)  
A DVP-SLP24 adapter may also be used with a 24 inch  
vertical section of SLP series vent pipe.  
After the 48 inch vertical section, the venting table rules  
must be followed. The first 48 inch vertical section is NOT  
counted as part of the vertical components in the table. It is  
still counted as part of the overall maximum run. All venting  
table rules for the vent run must still be followed.  
20 ft max.  
(6.10 m)  
Example: DVP pipe 3 ft. min. vertical = 11 ft. max. horizontal  
SLP pipe 7 ft. min. vertical = 11 ft. max. horizontal  
WARNING  
Fire Risk. Explosion Risk.  
Do NOT pack insulation or other combustibles  
between ceiling firestops.  
• ALWAYS maintain specified clearances around  
venting and firestop systems.  
Top Vent—Horizontal Termination—Two 45º Elbows  
Installation requirements to replace the first 90º elbow  
with two 45º elbows:  
• Install wall shield and ceiling firestops as speci-  
fied.  
Failure to keep insulation or other material away  
from vent pipe may cause fire.  
Figure 7.3  
WARNING  
Fire Risk.  
• When using DVP-HRC-SS and DVP-HRC-ZC-  
SS termination caps on top vented fireplaces, a  
6 inch minimum vertical vent section is required  
before installing first elbow.

Vent Clearances and Framing  
8
A. Pipe Clearances to Combustibles  
B. Wall Penetration Framing  
WARNING! Risk of Fire! Maintain air space clearance to  
vent. DO NOT pack insulation or other combustibles:  
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  
• The opening must be framed on all four sides using the  
same size framing materials as those used in the wall  
construction.  
Failure to keep insulation or other material away from  
vent pipe may cause over heating and fire.  
• SLP pipe - A wall 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.  
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. a DVP-HSM-B will be required.  
• 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 (refer to Section 16.B.)  
attached to them.  
• 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. a DVP-HSM-B will be required.

C. Install the Ceiling Firestop  
A ceiling firestop MUST be used between  
floors and attics.  
• DVP pipe only - Frame an opening 10 in.  
by 10 in. (254 mm by 254 mm) whenever  
the vent penetrates a ceiling/floor (see  
Figure 8.3).  
ATTIC ABOVE  
• SLP pipe only - Frame opening 9 in. x 9  
in. (229 mm x 229 mm) whenever the vent  
penetrates a ceiling/floor (see Figure 8.3).  
• Frame the area with the same sized lumber  
A
as used in ceiling/floor joist.  
• The ceiling firestop may be installed above or  
below the ceiling joists when installed with a  
attic insulation shield. It must be under joists  
between floors that are not insulated. Refer  
to Figure 8.4.

Troubleshooting  
15  
With proper installation, operation, and maintenance your gas appliance will provide years of trouble-free service. If you do  
experience a problem, this troubleshooting guide will assist a qualified service technician in the diagnosis of a problem and  
the corrective action to be taken. This troubleshooting guide can only be used by a qualified service technician. Contact  
your dealer to arrange a service call by a qualified service technician.  
A. IntelliFire PlusTM Ignition System  
Symptom  
Possible Cause  
Corrective Action  
1. Pilot won’t light.  
The ignitor/module  
makes noise, but no  
spark.  
A. Incorrect wiring.  
Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are  
connected to correct terminals on module and pilot assembly.  
B. Loose connections or electrical  
shorts in the wiring.  
Verify no loose connections or electrical shorts in wiring from mod-  
ule to pilot assembly. Verify connections underneath pilot assembly  
are tight; also verify igniter and flame sense wires are not grounding  
out to metal chassis, pilot burner, pilot enclosure, mesh screen if  
present, or any other metal object.  
C. Ignitor gap is too large.  
Verify gap of igniter to right side of pilot hood. The gap should be  
approximately .17 in. or 1/8 in. (3 mm).  
2. Pilot won’t light,  
there is no noise or  
spark.  
A. No power, transformer installed  
incorrectly, or depleted batteries.  
Verify that transformer is installed and plugged into module. Check  
voltage of transformer at connection to module. Acceptable read-  
ings of a good transformer are between 6.4 and 6.6 volts AC. Bat-  
tery power supply voltage must be at least 4 volts. If below 4 volts,  
replace batteries.  
B. A shorted or loose connection in  
wiring configuration or wiring har-  
ness.  
Remove and reinstall the wiring harness that plugs into module. Ver-  
ify there is a tight fit. Verify pilot assembly wiring to module. Remove  
and verify continuity of each wire in wiring harness. Replace any  
damaged components.  
C. Improper wall switch wiring.  
D. Module not grounded.  
Verify that 110/VAC power is “ON” to junction box.  
Verify black ground wire from module wire harness is grounded to  
metal chassis of appliance.  
3. Pilot sparks, but  
Pilot will not light.  
A. Gas supply.  
Verify that incoming gas line ball valve is “open”. Verify that inlet  
pressure reading is within acceptable limits.  
B. Ignitor gap is too large.  
Verify gap of igniter to right side of pilot hood. The gap should be  
approximately .17 in. or 1/8 in. (3 mm).  
C. Module is not grounded.  
D. Pilot valve solenoid.  
Verify module is securely grounded to metal chassis of appliance.  
Verify that 1.5 to 1.8 VDC is supplied to pilot solenoid from module.  
If below 1.5 volts, replace module. If 1.5 volts or greater, replace  
valve.

Troubleshooting (continued)  
Symptom  
Possible Cause  
Corrective Action  
A. A shorted or loose connection in flame  
Verify all connections to wiring diagram in manual. Verify  
connections underneath pilot assembly are tight. Verify  
flame sense or igniter wires are not grounding out to metal  
chassis, pilot burner, pilot enclosure or screen if present, or  
any other metal object.  
4. Pilot lights but contin-  
ues to spark, and main  
burner will not ignite.  
(If the pilot continues  
to spark after the  
pilot flame has been lit,  
flame rectification has  
not occurred.)

B. Poor flame rectification or contaminated With fixed glass assembly in place, verify that flame is en-  
flame sensing rod.  
gulfing flame sensing rod on left side of pilot hood. Flame  
sensing rod should glow shortly after ignition. With a multi-  
meter, verify that current in series between module and  
sense lead is at least 0.14 microamps. Verify correct pilot  
orifice is installed and gas inlet is set to pressure specifi-  
cations. Polish flame sensing rod with fine steel wool to  
remove any contaminants that may have accumulated on  
flame sensing rod.  
C. Module is not grounded.  
Verify module is securely grounded to metal chassis of ap-  
pliance. Verify that wire harness is firmly connected to the  
module.  
D. Damaged pilot assembly or contami-  
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 sens-  
ing rod with fine steel wool to remove any contaminants that  
may have accumulated on flame sensing rod. Verify conti-  
nuity with a multi-meter with ohms set at lowest range. Re-  
place pilot if any damage is detected.  
nated flame sensing rod.  
E. Module.  
Turn ON/OFF rocker switch or wall switch to OFF position.  
Remove ignitor wire “I” from module. Place ON/OFF rocker  
switch or wall switch in ON position. If there is no spark at “I”  
terminal module must be replaced. If there is a spark at “I”  
terminal, module is fine.
