What happens when I first light my fireplace?
When you first light your fireplace, there is a curing period. This can include a small amount of smoke and
odor. This is normal. Curing steps for your Mendota include:
Step 1: Expelling Initial Smoke and Odors
•
Complete the installation of any surround, front, doors, or safety screen.
•
Turn on the fireplace 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. Then turn off the fireplace and let it
cool.
Attention:
It is important that the blowers are 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 odor is expected during this step.
If desired, disable smoke alarms
before this step.
Smoke from the initial cure may set off smoke alarms.
Open doors and windows to
circulate fresh air.
Step 2: High Heat Curing Cycle
•
Turn on the fireplace 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 on and continue to Step 3.
Attention:
Odors initially may be strong. Open doors and windows to circulate fresh air if needed.
Step 3: Final Curing Cycle
•
Set the fan speed control to
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.
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 applications.
Finish materials around the fireplace are subject to high temperatures. Finishing materials used over the
fireplace in the non-combustible zone can reach 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. Reference the
“Additional Application Caution for Finish Materials”
section of the installation
manual for information on appropriate finishing materials.
It is normal for surfaces around the fireplace to be too hot to touch
. Provided that all clearances and R-value
requirements in the installation manual have been met, this is not a safety concern. 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.
