L. Frequently Asked Questions

ISSUE SOLUTIONS

Condensation on the glass

Blue fl ames

Odor from appliance

This is a result of gas combustion and temperature variations. As the appliance warms, this
condensation will disappear.

This is a result of normal operation and the fl ames will begin to yellow as the appliance is allowed
to burn for 20 to 40 minutes.

When fi rst operated, this appliance may release an odor for the fi rst several hours. This is caused
by the curing of materials from manufacturing. Odor may also be released from fi nishing materials
and adhesives used near the appliance. These circumstances may require additional curing
related to the installation environment.

Film on the glass

Metallic noise

Is it normal to see the pilot
fl ame burn continually?

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.

In an Intellifi re ignition system it is normal to see the pilot fl ame, but it should turn off when ON/
OFF is turned to OFF. 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:

fi restops 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 fl oor of the chase
should be insulated. Vapor and air infi ltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infi ltration may be an issue, the inside surfaces may
be sheetrocked and taped for maximum air tightness.

Treatment of ceiling fi restops and wall shield

1/2 in. (13 mm)

To further prevent drafts, the wall shield and ceiling fi re-
stops should be caulked with high temperature caulk to
seal gaps. Gas line holes and other openings should be
caulked with high temp caulk 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.

C. Clearances

NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly on
carpeting, vinyl, tile or any combustible material other than
wood.

WARNING! Risk of Fire! Maintain specifi ed air space
clearances to appliance and vent pipe:

• Insulation and other materials must be secured to
prevent accidental contact.

• Failure to maintain airspace may cause overheating and
a fi re.

Combustible flooring may be installed next
to the front of the appliance.

Vent Information and Diagrams

A. Approved Pipe

This appliance is approved for use with Hearth & Home
Technologies DVP and/or SLP venting systems. Refer to
Section 16B for vent component information.

DO NOT mix pipe, fi ttings or joining methods from differ-
ent manufacturers.

The pipe is tested to be run inside an enclosed wall.
There is no requirement for inspection openings at each
joint within the wall.

WARNING! Risk of Fire or Asphyxiation. This appliance
requires a separate vent. DO NOT vent to a pipe serving a
separate solid fuel burning appliance.

C. Use of Elbows

Diagonal runs have both vertical and horizontal vent aspects
when calculating the effects. Use the rise for the vertical
aspect and the run for the horizontal aspect (see Figure

7.1).
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.

• Pipe measurements are shown using the effective length
of pipe (see Figure 7.2).

• Horizontal terminations are measured to the outside
mounting surface (fl ange of termination cap).

• Vertical terminations are measured to bottom of
termination cap.

• Horizontal pipe installed level with no rise.

E. Vent Diagrams

To replace the fi rst 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 confi guration. Some elbows
may be installed horizontally. See Figure 7.9.

• Elbows may be placed back to back anywhere in the
system as long as the fi rst 90° elbow is a starter elbow
except as shown in Figure 7.4.

• When penetrating a combustible wall, a wall shield
fi restop must be installed.

• When penetrating a combustible ceiling, a ceiling
fi restop must be installed.

• Horizontal runs of vent do not require vertical rise;
horizontal runs may be level.

Note: The CD 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
(V

min.) requirements.

Vent Clearances and Framing

A. Pipe Clearances to Combustibles

WARNING! Risk of Fire! Maintain air space clearance to
vent. DO NOT pack insulation or other combustibles:

• Between ceiling fi restops

• Between wall shield fi restops

• Around vent system
Failure to keep insulation or other material away from

vent pipe may cause over heating and fi re.

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.

B. Wall Penetration Framing

Combustible Wall Penetration

Whenever a combustible wall is penetrated, you must
frame a hole for the wall shield fi restop(s). The wall shield
fi restop maintains minimum clearances and prevents cold
air infi ltration.

• 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 fi restop 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 fi restop is required on one side
only on interior walls. If your local inspector requires a
wall shield fi restop on both sides, then both wall shield
fi restops must have a heat shield attached to them.

• See Section 10.L. for information for regarding the
installation of a horizontal termination cap.

Non-Combustible Wall Penetration

If the hole being penetrated is surrounded by noncombus­tible materials such as concrete, a hole with diameter one
in. greater than the pipe is acceptable.

Whenever a non-combustible wall is penetrated, the wall
shield fi restop is only required on one side and no heat
shield is necessary.

C. Install the Ceiling Firestop

A ceiling fi restop MUST be used between
fl oors and attics.

• DVP pipe only - Frame an opening 10 in.
by 10 in. (254 mm by 254 mm) whenever
the vent penetrates a ceiling/fl oor (see
Figure 8.4).

• SLP pipe only - Frame opening 9 in. x
9 in. (229 mm x 229 mm) whenever the
vent penetrates a ceiling/floor (see Figure

8.4).

• Frame the area with the same sized lumber
as used in ceiling/fl oor joist.

• The ceiling fi restop may be installed above
or below the ceiling joists when installed
with a attic insulation shield. It must be
under joists between fl oors that are not
insulated. Refer to Figure 8.5.

• Secure with three fasteners on each side.

WARNING! Risk of Fire! DO NOT pack insu-

lation around the vent. Insulation must be kept
back from the pipe to prevent overheating.

requires the use of an attic shield.

The National Fuel Gas Code ANSI Z223.1 and NFPA 54
requires an attic shield constructed of 26 gauge minimum
metal that extends at least 2 in. (51 mm) above insulation.

Attic shields must meet specifi ed clearance and be se-
cured in place.

Flat Ceiling Installation

• Remove one shield from box.

NOTICE: Cut previously installed batt insulation to make
room for the attic insulation shield.

• Wrap shield around pipe if pipe is already installed in
area to be insulated.

• Match the three holes in each side and fasten with three
screws to form a tube.

• Bend three tabs on the bottom of the shield outward to
allow attachment to the ceiling fi restop.

• Bend the remaining bottom tabs inward 90° to maintain
the air space between the pipe and the shield. Set the
shield on the ceiling fi restop and attach to the fi restop.

• Bend all tabs inward 90° around the top of the shield.
These tabs must be used to prevent blown insulation
from getting between the shield and vent pipe, and to
maintain air space clearance.

Bend all tabs inward
90° to maintain
clearance and
prevent insulation
from falling inside

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 qualifi ed service technician in the diagnosis of a problem
and the corrective action to be taken. This troubleshooting guide can only be used by a qualifi ed service technician. Con-
tact your dealer to arrange a service call by a qualifi ed service technician.

A. Standing Pilot Ignition System

Symptom Possible Causes Corrective Action

1. After repeated triggering
of the red or black piezo
ignitor button, the spark
ignitor will not light the
pilot. Check for spark.

A. No gas or low gas pressure. Check the remote shut-off valves from the appliance. Usually, there

is a valve near the gas main. There can be more than one valve

between the appliance and the main.
B. No lp in tank. Check the LP (propane) tank. You may be out of fuel.
C. Ignitor. Check the spark at the electrode and pilot. If no spark and electrode

wire is properly connected, replace the ignitor. Verify that there is

no short in electrode wire.
D. Pilot or misaligned electrode

(spark at electrode).

Using match, light the pilot. If the pilot lights, turn off the pilot and

trigger the piezo ignitor button again. If the pilot lights, an improper

gas/air mixture caused the bad lighting and a longer purge period

is recommended. If the pilot will not light, ensure the gap at the

electrode and pilot is one-eighth inch to have a strong spark. If the

gap is OK, replace the pilot.

2. The pilot will not stay lit
after carefully following the
lighting instructions.

3. The pilot is burning, there
is no burner fl ame, the
valve knob is in the ON
position, and the ON/OFF
switch is in the ON
position.

A. Thermocouple. Check that the pilot fl ame impinges on the thermocouple. Adjust the

pilot for proper fl ame impingement.
Ensure that the thermocouple connection at the gas valve is fully

inserted and tight (hand tighten plus 1/4 turn).
Verify proper voltage output from the thermocouple to the valve.

Place one millivolt meter lead wire on the thermocouple copper
lead. Place the second lead wire on the solder button on the back
of the valve (blue wire). Start the pilot and hold the valve knob in.
The millivolt reading should read 8-16 millivolts. If millivolt reading
is less than 8 millivolts, replace thermocouple.

B. Improper gas inlet pressure. Natural gas should be 5-14 in. w.c. LP should be 10-14 in. w.c.

Verify pressure with manometer.

C. Control valve. If the thermocouple is producing 8-16 millivolts, replace control

valve.

A. On/off switch or wires

defective.

B. Thermopile may not be

generating suffi cient
millivoltage.

Check the ON/OFF switch and wires for proper connections. Place
the jumper wires across the terminals at the ON/OFF switch. If the
burner comes on, replace the ON/OFF switch. If the switch is OK,
place the jumper wires across the ON/OFF switch wires at the gas
valve. If the burner comes on, the wires are faulty or connections
are bad.

Check that the pilot fl ame impinges thermopile properly.
Be sure the wire connections from the thermopile at the gas valve

terminals are tight and that the thermopile is fully inserted into the
pilot bracket.

Check the thermopile with a millivolt meter. Take the reading at
TH-TP&TP terminals of the gas valve. The meter should read 350
millivolts minimum, while holding the valve knob depressed in the
pilot position, with the pilot lit, and the ON/OFF switch in the OFF
position. Replace the thermopile if the reading is below the specifi ed
minimum.

With the pilot in the ON position, disconnect the thermopile leads
from the valve. Take a reading at the thermopile leads. The reading
should be 350 millivolts minimum. Replace the thermopile if the
reading is below the minimum.

A. Standing Pilot Ignition System (continued)

Symptom Possible Cause Corrective Action

3. (Continued) C. Failed valve. Turn the valve knob to the ON position. Place the ON/OFF switch

in the ON position. Check the millivolt meter a the thermopile
terminals. The millivolt meter should read greater than 125mV. If the
reading is acceptable, and if the burner does not come on, replace
the gas valve.

D. Plugged burner orifi ce. Check the burner orifi ce for stoppage. Remove stoppage.

E. Wall switch or wires. Check the wall switch and wires for proper connections. Place the

jumper wires across the terminals at the wall switch. If the burner
comes on, replace the wall switch. If the wall switch is OK, place
the jumper wires across the wall switch wires at the gas valve. If the
burner comes on, the wires are faulty or connections are bad.

4. Frequent pilot outage

5. The pilot and main
burner extinguish while in
operation.

6. Glass soots. A. Flame impingement. Adjust the log set so that the fl ame does not excessively impinge on

A. Pilot fl ame may be too high or

too low, or blowing out (high
pressure), causing pilot safety
to drop out.

A. No LP in tank. Check the LP (propane) tank. Refi ll the fuel tank.
B. Improper gas inlet pressure. Verify with manometer. NG should read 5-14 inches w.c. LP should
