CAUTION: The X-62 should not be installed in any fireplace that is normally subject to severe downdrafts.
Downdraft conditions exist if, when starting a wood fire, it is difficult to establish a good upward draw
(i.e., smoke and cold air flow into the room rather than up the chimney), or if it is necessary to open a
door or window to get an upward flow of air established. For homes with downdraft conditions, we
recommend the installation of a ―lined‖ heater-rated fireplace insert (such as the Mendota DV-30 or DV-
40). NOTE: High winds or severely cold temperatures can cause downdrafts in any fireplace,
especially those with large flues. These occasional downdrafts do not preclude the use of a X-62.
NOTE: Do not connect the X-62 to a chimney flue serving a second solid-fuel-burning appliance.
NOTE: A chimney cap must be used with the X-62 to prevent rain from damaging the appliance.
MANTEL CLEARANCE
Combustible mantels located above the X-62 must conform to the minimum clearance distances listed in the chart
below. A mantel that is 8‖ (203 mm) deep or less must be at least 15‖ (381 mm) above the top of the exhaust
opening of the appliance. For mantles deeper than 8‖ (203 mm), the minimum clearance increases by 2‖ (51 mm)
for every 1‖ (25 mm) increase in mantle depth. (See Fig. 3.)

GAS SUPPLY REQUIREMENTS
CORRECT GAS PRESSURE AND PROPER GAS SUPPLY LINE SIZING ARE CRITICAL TO THE SUCCESSFUL
PERFORMANCE OF YOUR X-62 GAS LOG INSERT. BE SURE THAT THE GAS SUPPLIER OR PLUMBER CHECKS FOR
CORRECT GAS PRESSURE AND GAS LINE SIZING WHEN INSTALLING THE APPLIANCE.
GAS SUPPLY PIPING MUST INCLUDE A DRIP LEG TO ELIMINATE THE POSSIBILITY OF CONTAMINANTS ENTERING THE
GAS TRAIN. MANY LOCAL CODES ALSO REQUIRE A SHUT OFF VALVE ON THE INCOMING GAS LINE. ADHERE
STRICTLY TO LOCAL AND NATIONAL CODES.
IF GAS SUPPLY PRESSURES EXCEED ½ PSIG [3.5KPA], THE APPLIANCE MUST BE ISOLATED FROM ITS SUPPLY WITH
AN APPROVED MANUAL SHUT-OFF VALVE. THIS MANUAL SHUT-OFF VALVE MUST BE CLOSED DURING ANY SUPPLY
LINE PRESSURE TESTING.
GAS SUPPLY LINE SIZING
The X-62 comes equipped with a 3/8" N.P.T. [1.0 cm] inlet on the main gas valve.
A gas line of sufficient size to deliver 63,000 BTUH to the unit at the normal inlet pressure must be run from the
supply regulator to the appliance. Refer to the following table and to local codes to determine the correct pipe
diameter.

Some areas allow the use of copper tubing or galvanized pipe. Check with local approval agencies and codes. NEVER use plastic pipe.
GAS PRESSURE REQUIREMENTS
A MAJOR CAUSE OF OPERATING PROBLEMS WITH GAS APPLIANCES IS IMPROPER GAS PRESSURE!
Such problems as changes in flame color or configuration, pilot or burner outages, intermittent operation, changes
in heat output, excessive burner noise, etc. can be the result of changes in gas pressure or improper gas pressure
at the time of installation. The most important item to check during installation, and the first thing to check when
problems occur, is gas pressure!
The natural gas supply normally enters a residence at ½ PSI [13‖ - 15‖ W.C.] [3.5 KPA]. A regulator located inside
the residence drops this pressure to 7‖ W.C. [1.8 KPA]. This ―inches to inches‖ regulator is sufficient to service
the existing gas appliances (stove, dryer, furnace, etc.). If the capacity of the regulator is not sufficient for the
addition of the X-62, a second ―inches to inches‖ regulator must be installed. EXCEPTION: Some codes allow 2
PSI [1.4 KPA] gas supplies to enter the residence, in which case ―pounds to inches‖ regulators are used.
The following table provides information on the requirements for correct gas pressure. Be sure your gas supplier
or plumber follows these requirements carefully.

INSTALLATION INSTRUCTIONS
NOTE: The X-62 Gas Log Insert must be installed only by a qualified technician.
1. Check to be sure that the fireplace into which the X-62 is to be installed meets ALL of the installation
requirements listed on page 5, that is:
a. The fireplace must be vented and non-combustible, have a working flue, and be approved for burning
solid fuel. It must not be located in a bathroom, or in any room where sleeping accommodations are
provided.
b. The fireplace must be at least 30 ½‖ wide by 24‖ high by 16 ½‖ deep.
c. The chimney opening of the fireplace must equal or exceed the minimum opening for the height of the
chimney, as listed in the CHIMNEY OPENING chart on page 5.
d. The fireplace must not be subject to severe downdrafts during the normal course of its operation.
e. The chimney flue must not serve a second solid-fuel-burning appliance.
f.The chimney of the fireplace must be equipped with a chimney cap.
2. Check to see that the gas supply meets ALL of the requirements listed on page 6, that is:
a. The gas supply line must of the proper material and must be of the proper diameter, as listed in the
GAS SUPPLY LINE SIZING chart on page 6. Also, the gas supply line must have a drip leg, a shut-
off valve (if one is required by local codes or if the supply gas pressures exceed ½ PSIG [3.5KPA]),
and a regulator of sufficient capacity.
b. Flex hose used to connect the appliance must have brass-to-brass fittings.
c. The gas pressure must meet the requirements listed in the INLET GAS PRESSURE chart on page 6.
3. Remove any glass doors, grates, combustible materials, etc. from the existing fireplace.
4. Have the fireplace and venting system cleaned by a certified chimney sweep or qualified service technician.
The damper of the fireplace must be modified to maintain at least the minimum opening required for
the height of the chimney, as listed in the CHIMNEY OPENING chart on page 5. It is recommended
either to remove the damper completely, or to cut a hole in the damper equal the minimum opening
required. A large damper may be permanently fixed open with a screw or bolt in its edge, provided that
the opening meets the minimum requirements.
NOTE: Massachusetts requires that the existing fireplace flue damper must be removed or
permanently welded in the "open" position.
5. Remove the log package, the bag of coals, the grate, the bag containing the remote and batteries, the L.P.
conversion kit, the packing material, and any other loose items in the firebox. Set the X-62 in front of the
fireplace.
6. Take out the front vent plate by removing the 2 screws that hold it to the firebox floor (see Fig. 6). Plug the
receiver wire into the receiver (see Fig. 7, page 8).
Figure 6

Figure 7
IF THE X-62 IS TO BE OPERATED ON NATURAL GAS, PROCEED TO STEP #8.
7. The X-62 can operate on either Natural Gas or L.P. Gas. It arrives from the factory set up for operation on
Natural Gas. If the appliance is to be operated on L.P. Gas, a qualified technician must convert the gas valve
and the pilot from Natural Gas to L.P. Gas, and install all of the components in the L.P. Conversion Kit that is
provided with the appliance. To convert the appliance to L.P. Gas (see Fig.5):
a. Take out the burner: Remove the 4 screws that hold the burner to the firebox floor (see Fig.5, page 4).
Slide the burner to the left to disengage its inlet tube from the shutter box. Lift the burner up.
b. Take out the firebox floor by removing the 6 screws that hold it to the firebox (see Fig 5, page 4).
c. Unscrew and remove the Natural Gas orifice that was shipped with the X-62 (see Fig.4, page 4). Save
the orifice removed from the appliance for future use. [Conservez les injecteurs retirés de ĺappareil
pour utilisation future.]
d. Screw the L.P. orifice (which is part of the L.P. Conversion Kit) over the fitting on the gas valve.
e. To convert the valve to L.P. Gas, remove the rubber cap that covers the valve conversion stem.
Depress the stem and rotate it clockwise until it locks in place in the depressed position. Replace the
rubber cap. (See Fig.4, page 4.)
f.To convert the pilot to L.P. Gas, loosen the ½‖ hex fitting under the pilot hood, slide the quick adjust
lever forward (the lever is just below the hex fitting), and tighten the hex fitting (see Fig. 8).
g. Reinstall the firebox floor, the front vent plate, and the burner, in that order. To reinstall the burner, set
it in place in the left side of the opening in the firebox floor (the opening of the burner inlet tube should
be pointing to the right. Slide the burner to the left until the inlet tube engages with the shutter box
and the screw holes line up. Screw the burner in place.
Figure 8
To convert the X-62 back to natural gas, replace the L.P. orifice with the Natural Gas orifice according to the
instructions above. Also convert the gas valve and the pilot back to natural gas. Remove the rubber cap that
covers the valve conversion stem. Push in on the stem and rotate it counterclockwise until it pops out to its
full extension. Replace the rubber cap. To convert the pilot, loosen the ½‖ hex fitting under the pilot hood,
slide the quick adjust lever backward (the lever is just below the hex fitting), and tighten the hex fitting.

9
8. Connect the 3/8‖ npt flex connector (with shut-off valve) of the X-62 to the gas supply line. Take care not to
damage or kink the flex connector.
9. Check the connections for leaks. Use a solution of soap and water, and check for bubbling. IT IS CRITICAL
TO CHECK CAREFULLY FOR LEAKS!
10. Make sure all gas supply shut-off valves are open. Bleed air from supply lines. Light the X-62, and adjust the
burner to its highest setting (see OPERATING INSTRUCTIONS, page 12). Check the manifold pressure at
the pressure tap fitting on the gas valve (see Fig. 4, page 4). Manifold pressure must meet the requirements
listed in the INLET GAS PRESSURE chart on page 6 (gas pressure may vary by ± 5%).
11. Cycle the burner on and off several times to make certain that it lights promptly, and that flames cover all parts
of the burner pan. NOTE: Never turn the burner on or off quickly—always allow the X-62 to burn at least 60
seconds before turning it off, and to rest at least 60 seconds before turning it on.
12. Plug the power cord for the blower into a grounded 115-volt outlet. The outlet must be electrically grounded in
accordance with local codes, or in the absence of local codes, with the National Electric Code ANSI/NFPA 70-
1987. NOTE: The blower for the X-62 is equipped with an 8-ft power cord. If an electrical outlet has not been
wired into the existing fireplace, check to be sure that an outlet is located within reach of the power cord when
the appliance is in its installed position. Extension cords are not allowed.
13. Slide the X-62 into the fireplace, and check to see that it is level and plumb with the fireplace opening. If not,
the appliance should be squared to the opening by placing metal shims, metal washers, brick, or other non-
combustible materials beneath it.
IF YOU PURCHASED AN OPTIONAL BRICK KIT FOR YOUR X-62, INSTALL IT NOW ACCORDING TO
THE INSTRUCTIONS THAT ACCOMPANY THE KIT. THEN PROCEED TO STEP 14.
14. Open the bag of coals. Spread the coals on top of the burner to produce a glowing ember effect, and also
around the base of the burner to conceal it (see Fig. 6). DO NOT spread any coals over the slots at the front
of the appliance, as these may inhibit airflow. NOTE: Use only the larger chunks of coals—DO NOT use any
tiny fragments or coal dust, as these might clog the burner.
Positioning of the coals on the burner has a major impact on the appearance of the flame and the glow.
More coals = more glow but less flame. Fewer coals = more flame but less glow.
15. Set the grate in place over the burner (see Fig. 9, page 10). The grate should be centered left to right in the
firebox. The tines at the back of the grate should rest on the ledge in the back of the firebox. Slide the grate
as far back in the firebox as it will go.
16. Carefully open the log package, and remove the logs. Position the logs on the grate as shown in Fig. 9 (page
10). The grate and the log pile should be centered in the firebox. CAUTION: DO NOT position the logs so
that they obstruct the pilot flame—any obstruction of the pilot flame may inhibit the prompt, safe lighting of the
burner.
NOTE: The logs will produce a strong, acrid odor on initial contact with the flames. This is completely normal.
The odor will dissipate after about an hour of operation.
17. Cycle the burner on and off several times to make certain that it lights promptly, and that flames are distributed
throughout the log pile. If there is any delay in lighting, it is necessary to check for the correct positioning of
logs and coals—logs and coals must not obstruct the pilot flame. NOTE: Never turn the burner on or off
quickly—always allow the X-62 to burn at least 60 seconds before turning it off, and to rest at least 60 seconds
before turning it on.
18. Take out the front vent plate by removing the 2 screws that hold it to the firebox floor (see Fig.6, page 7).
Loosen the nut that holds the air shutter in place (see Fig.10, page 10). Light the burner, and allow the X-62
to burn for 2-3 hours. At this point, small additional adjustments may need to be made to the air shutter to
improve the appearance of the flame.

10
Figure 10
NOTE: Very small changes in air shutter position make major changes in the appearance of the flame.
a. If the flame is too blue, push the air shutter away from you in small increments (about 1/16‖) until the
appearance of the flame improves. Tighten the nut of the air shutter. Replace the front vent plate,
and screw it to the firebox floor.
b. If the flame is too orange, or if sooting occurs, pull the air shutter toward you in small increments
(about 1/16‖) until the appearance of the flame improves. Tighten the nut of the air shutter. Replace
the front vent plate, and screw it to the firebox floor. NOTE: If sooting persists, turn off the appliance,
and call your Mendota dealer.
19. Install the Faceplate / Surround, Screen, and other facings and trims according to the instructions included
with them.
Figure 9
WARNING: Failure to position the logs in accordance with Fig.8 or failure to use only parts specifically
approved with this appliance may result in property damage or personal injury.
Place the grate above the burner and coals by resting the three center bars on the ledge located on the
rear wall of the firebox. Center the grate left to right over the burner.

OPERATING INSTRUCTIONS
LIGHTING
1. Grab the damper of the X-62 with the damper hook. Pull the damper forward until it slides over the latch at
the front of the unit (see Fig. 11). NOTE: The appliance will not light unless the damper is pulled all the
way forward—the pilot will spark for 60 seconds and then will shut off.
FIGURE 11
2. Press the ―ON‖ button of the remote. DO NOT tap and release the button quickly, but hold it down firmly
until the X-62 lights. The appliance should light almost immediately, and the button can be released.
NOTE: Never turn the burner on or off quickly—always allow the X-62 to burn at least 60 seconds before turning it
off, and to rest at least 60 seconds before turning it on.
CAUTION: THE BURNER SHOULD LIGHT ALMOST IMMEDIATELY AFTER PRESSING THE ―ON‖ BUTTON OF THE REMOTE
CONTROL. IF THE BURNER DOES NOT LIGHT PROMPTLY, IMMEDIATELY RELEASE THE BUTTON. WAIT AT LEAST 60
SECONDS, AND TRY AGAIN. IF THE BURNER DOES NOT LIGHT PROMPTLY AFTER THE SECOND TRY, REPLACE THE
BATTERIES IN THE REMOTE, AND TRY ONCE MORE. IF THE BURNER STILL FAILS TO LIGHT PROMPTLY, CALL YOUR
LOCAL MENDOTA DEALER.
OPERATION
The X-62 will burn continuously until it is turned off. Press the ―HI‖ button on the remote to operate the appliance
with maximum flame and heat. Press the ―LOW‖ button on the remote to operate the appliance with minimum
flame and heat.
BLOWER OPERATION
To increase its heating capacity, the X-62 is equipped with a dual blower system. To increase the heating
capacity. Provided that the rheostat is turned ―ON‖, the blower operates automatically when the appliance is
burning. NOTE: After the appliance is turned on, it must heat up for approximately 15 minutes before the blower
comes on. Similarly, after the appliance is turned off, the blower will run for a cool-down period lasting
approximately 10 minutes. These times could be longer if the optional firebrick was installed.
The blower speed can be adjusted high/low or on/off as desired (see Fig. 5). First remove the firescreen. To turn
the blower on, turn the rheostat knob clockwise until it clicks. The speed of the blower can be adjusted higher (by
turning the rheostat knob clockwise) or lower (by turning the rheostat knob counterclockwise). To turn the blower
off, turn the rheostat knob counterclockwise until it clicks. NOTE: It is not necessary to turn the blower off
manually when the fireplace is turned off; the blower will shut off automatically after about 10 minutes. Replace
the firescreen after adjusting the blower.

HEATING PERFORMANCE
NOTE: The X-62 is a decorative gas appliance. It has been designed as a source of supplemental heat only.
It should not take the place of, or be used as, a whole-house heating system. NEVER overfire by
increasing the BTUH above the nameplate specifications.
To maximize heat circulation, provide the appliance with good air movement by using ceiling fans, through-the-wall
grills, floor grills, or the blowers of your central heating and cooling system.
The best means of heat distribution is a ceiling fan. We recommend the use of a ceiling fan for anyone who
wishes to utilize the heat of the X-62 most efficiently. CAUTION: Make sure that the ceiling fan does not blow air
directly onto the flames. Disturbing the flames can lead to sooting.
In warm weather, or whenever a log fire is desired but warmth is not, the flame of the X-62 can be reduced to
approximately 33,600 BTUH by pressing the ―LOW‖ button on the remote (to turn down the flame), and by turning
the rheostat knob on the front of the unit counterclockwise to the ―OFF‖ position (to turn off the blower).
SHUT DOWN PROCEDURE
Press the ―OFF‖ button on the remote control, and hold it briefly until the flame shuts off. If the blower was turned
on, it will remain running for a 5-minute cool-down period, and then will shut off automatically. Grab the damper
with the damper hook. (See Fig.7.) Lift the damper up off the latch at the front of the unit, and slide the damper
back into the unit as far as it will go. NOTE: The damper may be left in the open position unless cold downdarfts
are a problem, in which case the damper should be closed.
TROUBLESHOOTING THE X-62 GAS LOG INSERT
SYMPTOM
PROBABLE CAUSES
CORRECTIVE ACTION
1. The appliance fails to light.
A. The remote is too far from
the receiver.
B. The gas supply is turned off.
C. The batteries in the remote
and/or receiver need
replacing.
D. The remote needs to be
synchronized with the
receiver.
E. The pilot assembly is dirty.
F. Any other cause.
A. Make certain that the remote is within the 20-foot operational
range.
B. Turn on the gas supply to the appliance.
C. Replace the batteries in the remote and/or receiver. To change
the batteries in the receiver, take off the front vent plate by
removing the 2 screws that hold it to the firebox floor. Pull the
battery box, which is held down by Velcro, out of the unit (see
Fig.12). Slide the cover open, and replace the batteries—make
certain that they are installed in the proper direction. Close the
cover, stick the receiver to the Velcro pad, and replace the front
vent plate.
D. Take off the front vent plate by removing the 2 screws that hold it
to the firebox floor. Using a small screwdriver or other pointed
device, press the button on the receiver and HOLD IT IN (see
Fig. 13). Press the ON button of the remote—the pilot will spark
when the remote is synchronized. Replace the front vent plate.
E. Clean the pilot assembly with compressed air, available at most
electronics stores, to remove any dust or debris that has clogged
the pilot opening.
F. Call your Mendota dealer.
2. A thin black coating of soot
forms on the firescreen.
A. Incorrect gas pressure.
B. Not enough combustion air.
A. Have your gas supplier check for the correct gas pressure [7"
W.C. Nat.Gas; 11" W.C. LP Gas].
B. Open the air shutter on the burner [see "INSTALLATION
INSTRUCTIONS" step 18 b]. If sooting still continues, turn off
the unit and call your Mendota dealer.
3. Humming or whistling comes
from the appliance.
A. Normal operating noise.
A. Some noise is normal. It is caused by the gas supply flowing
through the gas orifice, and is to be expected from any gas
fireplace. The noise can be reduced operating the appliance on
its ―LOW‖ setting, though this will reduce the amount of flames
and therefore the heat output.

15
4. The appearance of the flame
or the operation of the burner
changes.
A. A change in gas pressure.
B. The burner, pilot, air shutter,
and logs need cleaning.
A. Have your gas supplier check for the correct gas pressure [7"
W.C. Nat.Gas; 11" W.C. LP Gas]. If the flame still is not right,
adjust the air shutter on the burner [see "INSTALLATION
INSTRUCTIONS" step 18 b].
B. Clean out carbon, dust, spider webs, lint, pet hair, etc. from these
areas.

MAINTENANCE
MAINTENANCE OF THE X-62 GAS LOG INSERT IS REQUIRED ANNUALLY.
We recommend that the following procedures be performed every year by your Mendota dealer:
1. Inspect and clean the control valve and burner: Check the condition of the wiring for melting or damage
from rodents. Clean all foreign matter from around the control valve and the air shutter on the venturi. Use a
brush or wire to clean the inlet of the venturi. Clean foreign matter and carbon deposits from the burner pan
and burner tiles. Check to see that the burner tiles are still porous.
2. Inspect and clean the pilot: Clean away any carbon deposits. Check the appearance of the pilot flame.
3. Inspect the gaskets: All gaskets must be tight. Replace them, if necessary.
4. Inspect the exhaust opening and the front vent plate: Make sure both areas are free from foreign matter
and other obstructions. Never block these openings.
5. Check the operation of the system: Cycle the burner on and off according to the procedure listed in
INSTALLATION INSTRUCTION step 17. Reposition the logs and the coals, if necessary.
6. Inspect the chimney: Check that chimney flue and outlet are open and free of blockage.
In addition, the homeowner periodically should dust the firescreen. The glass of any accessories may be cleaned
with standard glass cleaner, as needed.
