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

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.

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 enclosed inside the chase.

NOTICE: Treatment of ceiling ﬁ restops and wall shield 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.

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.

Vent Information and Diagrams

A. Approved Pipe

This appliance is approved for use with Hearth & Home Technologies DVP and SLP venting systems. Refer to Sec-

tion 16B for vent component information. DO NOT mix pipe, ﬁ ttings or joining methods from different

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.

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).

• Measurements are made from the appliance outer wrap,

not from the standoffs.

• Horizontal terminations are measured to the outside

mounting surface (ﬂ ange of termination cap) (see Figure

6.5).

• Vertical terminations are measured to bottom of

termination cap.

• Horizontal pipe installed level with no rise.

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 (216 mm) inches horizontal run and 8-1/2 (216 mm) inches vertical run. A length of straight pipe is allowed between two 45º elbows (see Figure 7.1).

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.

• 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 7.3.

• 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 NDV 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

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.

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. a DVP-HSM-B 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. a DVP-HSM-B will be required.

B. Wall Penetration Framing

Combustible Wall Penetration

Frame a hole in a combustible wall for an interior wall shield ﬁ restop, (Figure 8.2) whenever a wall is penetrated.

The opening must be framed on all four sides using the same size framing materials as those used in the wall construction. The wall shield ﬁ restop maintains minimum clearances and prevents cold air inﬁ ltration.

Non-Combustible Wall Penetration

If the hole being penetrated is surrounded by noncombustible materials such as concrete, a hole with diameter 1 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.

If your local inspector requires the wall shield ﬁ restop on both sides, then both wall shield ﬁ restops must have a heat shield attached to them.

D. Install Attic Insulation Shield

WARNING! Fire Risk. DO NOT allow loose materials or insulation to touch vent. Hearth & Home Technologies Inc. requires the use of an attic shield.

The National Fuel Gas Code ANSI Z223.1 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.

Note: 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 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.

Insert 3 screws

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 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 technician. Contact your dealer to arrange a service call by a qualiﬁ ed 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 switch. If the burner comes on, replace the defective switch. If the switch is OK, place the jumper wires across the 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.

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. Follow the corrective action in Symptom and Possible Cause 1.a

above. Check the switch and wiring.

4. Frequent pilot outage

5. The pilot and main

burner extinguish while in operation.

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

assembled pipe sections.

D. Glass installed improperly. Check to ensure glass is installed properly. Replace glass panel

assembly.

E. Failed thermopile or

thermocouple.

F. Improper vent cap installation. Check for proper installation and freedom from debris or blockage.

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

B. Improper air shutter setting. Refer to manual for shutter set points. Ensure that set point is

Ensure that the vent system joints are tight and have no leaks. Ensure that no debris has been placed at the base of, or in the area

of the air holes in the center of the base pan beneath the burner.

Ensure that the glass is tightened properly on the unit, particularly on top corners.
