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 components 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.

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
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.
Metallic noise
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.

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.
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 wall shield and ceiling
firestops 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 slab, a layer of plywood may be

E. Vent Diagrams
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:
•
•
•
•
•
•
•
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.
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.
Note: The NNXT 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.
When looking at horizontal termination diagrams, the
adapter is not counted as part of the minimum vertical
(V1 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.

The opening must be framed on all four sides using the
same size framing materials as those used in the wall
construction.
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.
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.

Troubleshooting
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 Plus™ Intermittent Ignition System
Symptom
Possible Cause
1. Pilot won’t light.
A. Incorrect wiring.
The ignitor/module
makes noise, but no
B. Loose connections or electrical
spark.
shorts in the wiring.
2. Pilot won’t light,
there is no noise or
spark.
3. Pilot sparks, but
Pilot will not light.
66
Corrective Action
Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are
connected to correct terminals on module and pilot assembly.
Verify no loose connections or electrical shorts in wiring from module 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).
A. No power or transformer installed
incorrectly.
Verify that transformer is installed and plugged into module. Check
voltage of transformer at connection to module. Acceptable readings of a good transformer are between 6.4 and 6.6 volts AC.
B. A shorted or loose connection in
wiring configuration or wiring harness.
Remove and reinstall the wiring harness that plugs into module.
Verify 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.
Verify that 120/VAC power is “ON” to junction box.
D. Module not grounded.
Verify black ground wire from module wire harness is grounded to
metal chassis of appliance.
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.
Verify module is securely grounded to metal chassis of appliance.
D. Pilot valve solenoid
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.

Intellifire Plus Intermittent Pilot Ignition System - (continued)
4. Pilot lights but continues 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.)
A. A shorted or loose connection in
flame sensing rod.
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.
B. Poor flame rectification or contaminated flame sensing rod.
With fixed glass assembly in place, verify that flame is engulfing
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 specifications. 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 appliance.
Verify that wire harness is firmly connected to the module.
D. Damaged pilot assembly or contaminated flame sensing rod.
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 multi-meter with ohms set
at lowest range. Replace pilot if any damage is detected.
