READ ME FIRST
1.1 INITIAL FIRING AND CURING PROCEDURE
This product requires an initial heat curing cycle during which some materials used in the manufacturing process will burn
off and the powder paint goes through a hardening cycle. During the initial curing phase, some smoke and odor will be
emitted. This is normal.
The installer should perform these initial curing cycle procedures as the final step in the installation process before
finishing materials are installed around this fireplace. See chapter Mendota Fireplace Insert Curing Instructions. Read and
follow all instructions given in this Chapter and perform the 3-step curing cycle.
After the 3-step curing cycle has been completed, all smoking will have stopped. Some slight odors may remain. With
subsequent use of this Insert, odors will slowly dissipate and disappear.
ODOR RISKS
If the Woodburning fireplace firebox and chimney flue are not inspected and cleaned as required, the
heat from this Insert body and vent system may cause existing dirt, creosote, or mold to emit odor.
If this appliance is not operated for an extended period (three months or longer), when first fired
again, expect odors of burnt dust and lint; just like when turning on your home heating system for the
first time in the Fall.
1.2 HOT SURFACES ARE NORMAL
Mendota Inserts comply with ANSI Z21.88-2017 Standards for maximum surface temperatures (ambient plus 117oF) on
exposed “combustible” surfaces adjacent to the Insert.
Be aware that the surface in front of, above and adjacent to this heater appliance can be too hot to touch. As long as all
required clearances to combustibles are met and the required finishing materials are used, this appliance will perform
safely. Note that the exposed surfaces immediately surrounding the Insert can have surface temperatures that are too hot
to touch. This level of surface temperature is considered normal and does not indicate any hazardous situation.
WARNING: The supplied barrier screen must be installed always when this fireplace is in operation.
Do not place any object directly in front (within 60”) or directly above (on the front edge of the
mantel). This is a heating appliance. Areas directly in front and above this appliance will be very hot
and can damage most household objects if placed too close. Keep Furniture pieces at least 60” away
in front of the barrier screen.
1.3 PERIODIC AND ANNUAL CLEANING ARE REQUIRED
See Required Periodic Inspections and Required Annual Maintenance.Periodic and Annual cleaning and general services
are required at least once a year in the Summer or early Fall. Changing remote control batteries at least every 6 months is
required; or more frequently based upon usage frequency. Cleaning pilot flame sensor rod, sparker rod and pilot hood
body is required at least once per year. Cleaning of burner ports, gas orifice areas is required once a year due to insects’
nesting probability due to Mercaptan addition in Natural Gas (Mercaptan attracts insects).
1.4 KEEP THE FLUE WARM
It is required to activate the Continuous Pilot Mode (CPI) to leave the pilot light running during winter months when
outside daily high temperatures remain 50oF or lower. Doing so will eliminate heat loss from the home through the
fireplace Insert glass door and will increase flue draft during startups and will aid in eliminating system lock out.

Caution: Before igniting the pilot or burners, perform the following inspections and verifications:
Check glass gasket seal. Visually inspect glass gasket, especially at the corners of the glass piece. Glass gasket is installed as a 4-
piece assembly. Check joints between the gasket pieces at the corners. They should butt against each other to create a seal. Gaps
between gasket pieces can cause exhaust leaks and lead to acrid smell concerns. Check for gas leaks at all fittings.
During the first burning cycle of this insert, ensure the convection blower is running at level three during the first two hours of
initial burn. After two hours of initial burn, allow fireplace to cool. Proceed with Mendota Fireplace Insert Curing Instructions.
This fireplace must be installed and serviced by a qualified installer, service agency, or the gas supplier. Any adjustments to
burner, pilot, logs, or coal bed must be made by a qualified installer, service agency, or the gas supplier.
If ignition system goes into lockout mode, always wait 5 minutes before attempting to re-light.
Never block off convection air openings or paths. Trim panels or surrounds shall not seal ventilation openings in the fireplace.
Always use Mendota decorative fronts and Mendota approved vent systems and vent caps only.

3.1.1 Mendota Fireplace Insert Curing Instructions
ATTENTION
It is important that the blowers are turned on during this step to prevent the curing smoke from staining the
wall finish above the fireplace. Mendota recommends completing Step 1 prior to installation of wall finish
materials.
Visible smoke and strong odor are to be expected during this step. If desired, disable smoke alarms before
this step, smoke from the initial curing cycle will set off smoke alarms. Open doors and windows of the home
to circulate fresh air.
3.1.1.1 Step 1: Expelling Initial Smoke and Odors
• Please refer to OPERATING INFORMATION,if you have questions on how to operate your Mendota.
• Complete the installation of any barrier screen (required), surround, front, or doors.
• Turn the fireplace on in the Manual (Off) thermostat mode.
• Set the Flame Height to Hi.
• Set the Fan Speed Control to Level 3.
• Run the fireplace with these settings for a minimum of 2 hours.
• Turn the fireplace off and let it cool.
3.1.1.2 Step 2: High Heat Curing Cycle
• Turn the fireplace on in the Manual (Off) thermostat mode.
• Set the Flame Height to Hi.
• Set the Fan Speed Control to Off.
• Run the fireplace with these settings until curing odors have diminished.
• When odors have diminished leave the fireplace turned on and continue to Step 3.
3.1.1.3 Step 3: Final Curing Cycle
• With the fireplace still turned on from Step 2.
• Set the Fan Speed Control to the lowest setting Level 1.
• If any new curing odors are detected continue to run the fireplace with this setting until the curing odors have diminished.
ATTENTION:Slight odors may still be noticeable on future startups of the fireplace. These will diminish over time as the fireplace
is used.
3.1.1.4 Additional Curing Information
It is not unusual for a fireplace to require more than 10 continuous hours on high for curing odors to diminish. There are
variables that can extend or shorten the curing time such as decorative fronts, doors, facing materials and their application.
Finish materials around the fireplace are subject to high temperatures. Finishing materials used over the fireplace in the non-
combustible zone can see temperatures around 350° F. Materials used around the fireplace must be rated for these
temperatures. Failure to use adequate materials can result in odor problems.
Please be aware that any material used around the fireplace will heat up and has the potential to cause odor issues. Adhesives,
glue, wall substrate, wall finish material, paints and polishes are common materials that if used incorrectly will cause odor issues.
Mendota is not responsible for any odor issues caused by materials used around the fireplace.
