INSTALLATION & OPERATING INSTRUCTIONS  
This gas fireplace should be installed by a qualified  
installer in accordance with local building codes and with  
current CSA-B149 (.1 or .2) Installation codes for Gas  
Burning Appliances and Equipment. For USA Installations  
follow local codes and/or the current National Fuel Gas  
Code. ANSI Z223.1. If the unit is being installed in a  
mobile home the installation should comply with the  
current CAN/USA Z240.4 Code.  
IMPORTANT:  
PLEASE REVIEW THE FOLLOWING CAREFULLY  
Remove any plastic from parts before turning the  
fireplace ON.  
It is normal for fireplaces fabricated of steel to give  
off some expansion and/or contraction noises  
during the start up or cool down cycle. Similar  
noises are found with your furnace heat exchanger  
or car engine. It is not unusual for your gas fireplace  
to give off some odor the first time it is burned. This  
is due to the curing of the paint and any undetected  
oil from the manufacturing process.  
Please ensure that your room is well ventilated-  
open all windows.  
It is recommended that you burn your fireplace for  
at least ten (10) hours the first time you use it. If the  
optional fan kit has been installed, place the fan  
switch in the “OFF” position during this time.  
FOR SAFE INSTALLATION AND OPERATION PLEASE  
NOTE THE FOLLOWING:  
1 . This fireplace gives off high temperatures and should  
be located out of high traffic areas and away from  
furniture and draperies.  
2. Children and adults should be alerted to the hazards  
of fireplace high surface temperatures and should  
stay away to avoid burns or ignition of clothing.  
3. CAUTION: Due to high glass surface temperature  
children should be carefully supervised when in  
the same room as fireplace.  
4. Under no circumstances should this fireplace be  
modified. Parts removed for servicing should be  
replaced prior to operating this fireplace again.  
5. Installation and any repairs to fireplace must be

GAS LINE INSTALLATION  
This appliance may be installed in an aftermarket  
permanently located, manufactured (mobile) home,  
where not prohibited by local codes.  
When purging the gas line, the front  
glass must be removed.  
This appliance is only for use with the type of gas  
indicated on the rating plate. This appliance is not  
convertible for use with other gases, unless a  
certified kit is available and used.  
The gas pipeline can be brought in through the rear of  
the fireplace as well as the bottom. Opening is provided  
on the bottom behind the valve to allow for the gas pipe  
installation and testing of any gas connecion. It is most  
convenient to bring the gas line in from the rear right  
side of the valve, as this allows fan installation or  
removal without disconnecting the gas line.  
Input ratings are shown in BTU per hour and  
are certified without deration for elevations up  
to 4,500 feet (1,370 m) above sea level.  
For elevations above 4,500 feet (1,370 m) in  
USA, installations must be in accordance with  
the current ANSI Z223.1 and/or local codes  
having jurisdiction.  
In Canada, please consult provincial and/or  
local authorities having jurisdiction for install-  
ations at elevations above 4,500 feet (1,370 m).  
The gas line connection can be made  
with properly tinned 3/8” copper tubing,  
3/8” rigid pipe or an approved flex con-  
nector. Since some municipalities have  
some additional local codes, it is always  
best to consult your local authority and  
the CSA-B149 (.1 or .2) installation code.  
For USA Installations consult the current  
National Fuel Gas Code, ANSI Z223.1.  
CFM186  
Always check for gas leaks with a mild  
soap and water solution. Do not use an  
open flame for leak testing.  
The gas control is equipped with a  
captured screw type pressure test point,  
therefore it is not necessary to provide a  
1/8” test point up stream of the control.

GENERAL INFORMATION ON ASSEMBLING  
THE VENT PIPES IN DIRECT VENT APPLICATIONS  
NOTE: Only venting components manufactured by The Vermont Castings Majestic Products Company may be used.  
TWIST LOCK PIPES  
CRIMPED END PIPES  
Before joining elbows and pipes apply a bead of high  
temperature sealant to the crimped end of the elbow or  
pipe. Join the pipes using a 2” (50mm) overlap and  
secure the joints with three (3) sheet metal screws  
(Fig. 11). Wipe off excess sealant.  
When using twist-lock pipe it is not necessary to use  
sealant on the twist lock joints.  
The only areas of the venting system that need to be  
sealed with high temperature silicone sealant are the  
collars on the fireplace and termination, and the sliding  
joint of any telescopic vent section used in the system.  
There are polished brass decorative  
rings available to hide the exposed  
piping joints. Wrap the brass ring over  
the joint fitting the stud into the notch  
and tighten down the 3/8” nut.  
To join the twist lock pipes together, simply align the  
beads of the male end with the grooves of the female  
end, twisting the pipe until the flange on the female  
end contacts the external flange on the male end.  
It is recommended that you secure the joints with three  
(3) sheet metal screws, however this is not mandatory  
with twist lock pipe.  
BEAD LOCATION  
1" FROM CRIMPED END OF PIPE  
To make it easier to assemble the joints we suggest  
putting a lubricant (Vaseline or similar) on the male  
end of the twist lock pipe.

Since it is very important that the venting system  
maintain its balance between the combustion air intake  
and the flue gas exhaust, certain limitations as to vent  
configurations apply and must be strictly adhered to.  
Total angular variation =  
270°  
The graph, on page 11, showing the relationship  
between vertical and horizontal side wall venting will  
help to determine the various lengths allowable.  
Minimum clearance between vent pipes and  
combustible materials is one 1” (25mm) on top, bottom  
and sides unless otherwise noted.  
When the vent termination exits through  
foundations less than 20” below siding outcrop,  
the vent pipe must flush up with the siding.  
It is always best to locate the fireplace in such a  
way that minimizes the number of offsets and  
horizontal vent length.  
Fig. 13  
The horizontal vent run refers to the total length of  
vent pipe from the flue collar of the fireplace to the  
face of the outer wall.  
Horizontal plane means no vertical rise exists on  
this portion of the vent assembly.  
7.5 ft.  
2286mm  
A + B = 17 ft.  
VERTICAL SIDEWALL APPLICATIONS  
• The maximum number of 90° elbows per side wall  
installations is three (3).  
Fig. 14  
• For IRFSDV24 and IRFSDV34 models the  
maximum horizontal run off a minimum 12” vertical  
rise is 3’ (see Fig. 15).  
3 FT  
(92cm)  
• If a 90˚ elbow is used in the horizontal vent run  
(level height maintained) the maximum horizontal vent  
length is reduced by 36 inches, (Fig. 14). This does not  
apply if the 90˚ elbows are used to increase or redirect  
a vertical rise (Fig. 16).

TO USE THE VENT GRAPH  
1. Determine the height of the center of the horizontal  
vent pipe exiting through the outer wall. Using this  
dimension on the Sidewall Vent Graph below, locate  
the point it intersects with the slanted graph line.  
2. From the point of this intersection, draw a vertical  
line to the bottom of the graph.  
3. Select the indicated dimension, and position the  
fireplace in accordance with same.  
Example A:  
If the vertical dimension from the floor of the  
fireplace is 11’ (3.4m) the horizontal run to the face  
of the outer wall must not exceed 14’ (4.3m).  
Example B:  
If the vertical dimension from the floor of the unit is  
7’ (2.14m), the horizontal run to the face of the  
outer wall must not exceed 8-1/2 (215mm).

Apply high temperature sealant to 4” (100 mm) and 7”  
(175 mm) collars or the termination one inch away from  
crimped end. Guide the vent terminations 4” and 7”  
collars into their respective vent pipes. Double check  
that the vent pipes overlap the collars by 2” (50mm).  
Secure the termination to the wall with screws provided  
and caulk around the wall plate to weatherproof.  
Measure the horizontal length requirement including a  
2” (50 mm) overlap, i.e. from the elbow to the outside  
wall face plus 2” (or the distance required if installing a  
second 90° elbow (Fig. 21).

STEP 6  
Note: If using the charcoal wall plate, Part #52202-CG,  
and collar, Part #52203-CG, put them in place before  
putting the pipe sections through the wall.  
Use appropriate length of pipe sections - telescopic or  
fixed - and install. The sections which go through the  
wall are packaged with the starter kit, and can be cut to  
suit if necessary (Fig. 22).

Check fireplace to make sure it is lev-  
elled and properly positioned.  
BELOW GRADE INSTALLATIONS  
When it is not possible to meet the required vent  
terminal clearances of 12 inches (305mm) above grade  
level a snorkel vent kit is recommended. It allows  
installation depth of down to 7 “ (178mm) below grade  
level. The 7 “ is measured from the center of the  
horizontal vent pipe as it penetrates through the wall.  
If venting system is installed below  
ground, we recommend a window well  
with adequate and proper drainage.  
Fig. 22  
Ensure sidewall venting clearances are observed.  
Sealing vent pipe and firestop gaps with  
high temperature sealant will restrict  
cold air being drawn in around fireplace.

OPERATING INSTRUCTIONS  
GENERAL GLASS INFORMATION  
INSTALLATION OF LOGS & BURNER  
LAVA ROCK MATERIAL  
Only glass approved by the Vermont  
Castings, Majestic Products Company  
may be used for replacement.  
Model: IRFSDV34  
Refer Figure 32.  
The use of substitute glass will void all pro-  
duct warranties.  
Care must be taken to avoid breakage of the glass.  
Under no circumstances should this  
fireplace be operated without the front  
glass or with a broken glass.  
1. Remove window frame assembly (See “Window  
Frame Assembly” section).  
2. Remove logs from packaging.  
Replacement of the glass (with gasket)  
as supplied by the manufacturer should  
be done by a licensed qualified  
service person.  
As with all plastic - these are not toys  
and should be kept away from children  
and infants.  
WINDOW FRAME REMOVAL  
3. Place rear log (KR10) on rear bracket (ensure  
log is seated properly, leveled and centered to  
the unit), so it will not move from side to side  
and it is firmly positioned on the bracket.  
4. Slip front ember log (KR7) down behind the  
front deflector.  
5. Place front left log (KR8) on top of burner, left  
side. Use log’s bottom holes to locate it into the  
left bracket log locator studs.  
1. Shut off gas (See Lighting Instructions).  
2. Let the unit cool if it has been operating.  
3. Open two side doors  
4. Open the clamps on two sides.  
5. Pull the frame forward.  
6. To reinstall window frame assembly follow the  
above procedure in reverse.  
6. Place front right log (KR9) on top of burner, right  
side. Use log’s bottom holes to locate it into the  
right bracket log locator studs.  
7. Place burner lava rock on top of burner  
between the ember log and the two front logs.  
8. Place top left log (KR11) onto locator notches.  
Ensure log is secure.  
Release clips  
(2 per side)

9. Place top right log (KR12) onto locator notches.  
Ensure log is secure.  
GLASS CLEANING  
It will be necessary to clean the glass periodically.  
During start-up condensation, which is normal, forms  
on the inside of the glass. This condensation causes  
lint, dust and other airborne particles to cling to the  
glass surface. Also initial paint curing may deposit a  
slight film on the glass. It is therefore recommended  
that the glass be cleaned two or three times with a  
non-ammonia based household cleaner and warm  
water (We recommend gas fireplace glass cleaner).  
After the initial cleaning process the glass should be  
cleaned two or three times during each operating  
season depending on the environment.

To shut off the system, turn the pilotstat knob clockwise  
to the OFF position. This action closes the main gas  
and safety valves. The transmitter cannot turn on the  
main burner or fan.  
3. Push plunger on the piezo until the pilot burner is lit.  
When the pilot burner is lit, the LED on the control  
will come on after approximately 40 seconds and  
will provide 1 short blink continuously in the normal  
mode. When the light turns off which will be approxi-  
mately 10 seconds after it has been continuously  
red, the receiver/valve is fully powered.  
TRANSMITTER OPERATION  
Off Mode  
In the OFF mode, the fireplace flame and fan are off,  
the display will show OFF and displays the room  
temperature. If the receiver is in REMOTE mode, the  
fireplace will shut off.  
4. Release the knob. The shaft will move upward. The  
pilot burner should now stay burning. If the pilot  
burner goes out, repeat step 2.  
5. Turn the knob counterclockwise to the ON position.  
If the manual switch is in the LOCAL position, the  
main burner will turn on immediately.  
On (Manual) Mode  
In the ON mode, the room temperature, flame and fan  
levels will be shown. MANUAL will appear next to both  
the flame and fan icons.  
6. ON the initial use of a transmitter, a recognition  
operation is required between the receiver/valve and  
transmitter. Change the switch from LOCAL to  
REMOTE. Press the fan or flame button on the  
transmitter within 30 seconds. The LED will blink  
indicating the transmitter will now work with the  
receiver/valve. If the switch continues in the RE-  
MOTE position, the transmitter will now control the  
main valve, flame modulation level and fan control.  
When the control is in the ON mode, the flame and fan  
levels, and delay timer are changed with the up and  
down buttons. To change the flame level, press the  
flame button followed by an arrow key. To change the  
fan level, press the fan key followed by an arrow key.  
Pushing the arrow key once will change the level by  
one unit.

Troubleshooting  
In the AUTO mode, the fan speed will increase with  
increasing flame height or decrease with decreasing  
flame height. “AUTO” is displayed next to the flame and  
fan icons.  
1. Locate LED light on valve.  
2. LED will blink after every valid command received  
by the transmitter; this is not an error.  
Fan Override During Auto Mode  
3. Failure codes may occur anytime after pilot burner  
is lit.  
If a lower or higher fan speed is desired when operat-  
ing in the AUTO mode, the fan speed can be overrid-  
den by pushing the fan button followed by the up or  
down key. Pushing a key once will change the fan level  
by one unit. In this mode “AUTO” is displayed next to  
the flame icon and “MANUAL” is displayed next to the  
fan icon.  
4. Sequence is failure code followed by light not  
blinking for 30 seconds.  
5. In the event of multiple failure codes, next failure  
code follows previous failure code by approximately  
3 seconds.  
If an Error Code 3 is observed while performing the  
testing, complete the following:  
Change Between F/C Temperature Units  
Push the up and down arrow keys simultaneously for at  
least 3 seconds to toggle between Fahrenheit and  
Celsius units.  
1. Make sure the spade connectors are pushed all the  
way on. If rhe Error Code 3 is still showing, then go  
to the next step.  
Disable Thermostat Function  
2. Switch the front two thermopile leads with the back  
two. Be sure the white lead is connected to the  
spade with the white dot next to it. If the Error Code  
3 is still showing, replace the thermopiles.  
To disable the thermostat function in the AUTO mode,  
push the time and down keys simultaneously for at  
least 3 seconds.  
If an Error Code 8 is observed while performing the  
testing, complete the following:  
To Change Batteries  
1. Remove cover on the backside of the transmitter.  
Install 3 AAA batteries as shown and reattach cover.  
1. Confirm the valve is not in REMOTE mode.  
• If the valve is producing Error Code 8 and in  
REMOTE mode, the valve is defective and should  
be replaced.  
2. Once steps 1-3 in OPERATION are completed,  
receiver/valve and transmitter are now ready. Press  
any button on transmitter for recognition process to  
occur between the receiver/valve and transmitter.  
• If the valve is in LOCAL mode and producing Error  
Code 8, then go to the next step.  
3. Use functions as described in TRANSMITTER section.  
2. Slide the Remote/Local switch to REMOTE and  
teach the valve a transmitter (see item 6, page 23).  
The Error Code will clear itself after approximately  
1.5 minutes and return to normal operation.
