ISSUE  
SOLUTIONS  
This is a result of gas combustion and temperature variations. As the replace warms, this  
condensation will disappear.  
Condensation on the glass  
This is a result of normal operation and the ames will begin to yellow as the replace is al-  
lowed to burn for 20 to 40 minutes.  
Blue ames  
When rst operated, this replace may release an odor for the rst several hours. This is  
caused by the curing of materials from manufacturing. Odor may also be released from  
nishing materials and adhesives used near the replace. These circumstances may require  
additional curing related to the installation environment.  
Odor from replace  
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.  
Film on the glass  
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 replace.

To further prevent drafts, the wall shield and ceiling 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 insu-  
lation. 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.  
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 restops and wall shield  
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.  
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.  
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.  
WARNING! Risk of Fire! Maintain specied air space  
clearances to appliance and vent pipe:  
Walls, ceiling, base plate and cantilever oor of the chase  
should be insulated. Vapor and air inltration barriers  
should be installed in the chase as per regional codes for  
the rest of the home. Additionally, in regions where cold  
air inltration may be an issue, the inside surfaces may  
be sheetrocked and taped for maximum air tightness.  
Insulation and other materials must be secured to  
prevent accidental contact.

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).  
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).

E. Vent Diagrams  
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.  
To replace the rst starter elbow with two 45° elbows,  
refer to Figure 7.4. All other 90° elbows can be replaced  
with two 45° elbows.  
When looking at horizontal termination diagrams, the  
adapter is not counted as part of the minimum vertical  
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 conguration. 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 rst 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  
restop must be installed.  
When penetrating a combustible ceiling, a ceiling  
restop must be installed.  
Horizontal runs of vent do not require vertical rise;  
horizontal runs may be level.

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 restop(s). The wall shield  
restop maintains minimum clearances and prevents cold  
air inltration.  
Between ceiling restops  
Between wall shield restops  
Around vent system  
Failure to keep insulation or other material away from  
vent pipe may cause over heating and re.  
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 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 restop is required on one side  
only on interior walls. If your local inspector requires a  
wall shield restop on both sides, then both wall shield  
restops 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.

A
Frame the area with the same sized lumber  
as used in ceiling/oor joist.  
The ceiling restop may be installed above or  
below the ceiling joists when installed with a  
attic insulation shield. It must be under joists  
between oors that are not insulated. Refer  
to Figure 8.4.  
Secure with three fasteners on each side.

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 qualied service technician in the diagnosis of a problem  
and the corrective action to be taken. This troubleshooting guide can only be used by a qualied service technician. Con-  
tact your dealer to arrange a service call by a qualied 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.  
C. Ignitor.  
Check the LP (propane) tank. You may be out of fuel.  
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 Using match, light the pilot. If the pilot lights, turn off the pilot and  
(spark at electrode).  
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.  
A. Thermocouple.  
Check that the pilot ame impinges on the thermocouple. Adjust the  
pilot for proper 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.  
C. Control valve.  
Natural gas should be 5-14 in. w.c. LP should be 10-14 in. w.c.  
Verify pressure with manometer.  
If the thermocouple is producing 8-16 millivolts, replace control  
valve.  
3. The pilot is burning, there A. On/off switch or wires  
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.

valve knob is in the ON  
position, and the ON/OFF  
switch is in the ON  
position.  
defective.  
B. Thermopile may not be  
generating sufcient  
millivoltage.  
Check that the pilot 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 specied  
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.
