CONGRATULATIONS! 

 

You are the owner of a world class, heat producing, gas, direct vent, sealed combustion fireplace. 

This elegant, highly efficient Fireplace will be a constant source of comfort and fascination.  It will be the focal point 
of beauty and interest in your home. 

The Mendota Gas Fireplace is a true heating appliance incorporating the traditional aesthetics of fireplace fire view-
ing with the controllability and fuel efficiency of a home gas furnace. Of particular interest is the low fuel consump-
tion and brilliant fire viewing afforded by the patented realistic HearthGlo wood fire-like combustion system. 

Carefully read the following instructions prior to actual installation.  Proper Mendota Gas Fireplace installation and 
operation will give you years of safe trouble free comfort and enjoyment. 

If you have any questions regarding installation or operation of your Mendota Fireplace please contact your local 
dealer. 

......CAUTION..... 

FOR YOUR SAFETY do not install or operate your Mendota Gas Fireplace without first reading and understanding 
this manual.  Any installation or operational deviation from this manual voids the Mendota Gas Fireplace Warranty 
and may prove hazardous! 

Due to high temperatures, the Fireplace should be located out of traffic and away from furniture and draperies.  Chil-
dren and adults should be alerted to the hazards of high surface temperature and should stay away to avoid burns or 
clothing ignition. Young children should be carefully supervised when they are in the same room as the Mendota Gas 
Fireplace. 

Clothing or other flammable material should not be placed on or near the Fireplace. 

The Mendota Gas Fireplace is a powerful, efficient heating unit.  It has been designed as a major source of supple-
mental heat. As with any mechanical appliance there can be component shut downs.  It is advisable to have an alter-
nate heat supply. 

Installation, repair and any adjustments to logs or burner must be done by a qualified service person.  The Fireplace 
should be inspected before use and at least annually by a professional service person.  More frequent cleaning may 
be required due to excessive lint from carpeting, bedding material, carbon build-up, etc.  It is imperative that control 
compartments, burners and circulating air passageways of the appliance be kept clean.  The burner and pilot flames 
and logs should be visually checked periodically. 

DO NOT use this Fireplace if any part has been under water or exposed to moisture corrosion.  Immediately call a 
qualified service technician to inspect the Fireplace and replace any part of the control system and any gas control 
which has been under water.  DO NOT use this fireplace if the burner does not light immediately.  Turn unit off and 
call Mendota approved service person if there is any delay in burner light-off. 

It is Johnson Gas Appliance Company's policy that no responsibility is assumed by the Company or by any of its 
employees or representatives for any damages caused by an inoperable, inadequate, or unsafe condition which is the 
result, either directly or indirectly, of any improper operation, installation or servicing procedures. 

BUILDING PERMIT AND INSTALLATION INSPECTION APPROVAL REQUIREMENTS 

All installations of Mendota Fireplaces and Inserts must comply with all the 

requirements stated in this Installation and Operating Instructions Manual.  The 
Dealer and/or installer must also obtain all required Building Permits and 
Inspection Approval from the local building inspection department or the local 
body having jurisdiction.  In order to validate warranty coverage, Mendota may 
require facsimile copies of the Building Permit and Inspection Approval forms.  
Failure to provide adequate proof that the installation conforms to all local 

requirements and the requirements stated in the Installation and Operating 
Instructions Manual will void all applicable warranty. 

INSTALLER:  THESE INSTRUCTIONS ARE TO REMAIN WITH HOMEOWNER.
