Safety Precautions

FOR SAFE INSTALLATION AND OPERATION OF YOUR “ENVIRO” HEATER, 

PLEASE CAREFULLY READ THE FOLLOWING INFORMATION:

•  All  ENVIRO  gas-fired  appliances  must  be  installed  in 

accordance with their instructions. Carefully read all the 

instructions  in  this  manual  first.  Consult  the  building 

authority having jurisdiction to determine the need for a 

permit prior to commencing the installation.
•  NOTE:

 Failure to follow these instructions could cause 

a malfunction of the fireplace, which could result in death, 

serious bodily injury, and/or property damage.
• Failure to follow these instructions may also void your 

fire insurance and/or warranty.

GENERAL

•  Installation  and  repair  should  be  done  by  a  qualified 

service person. The appliance should be inspected before 

the first use and, at least, annually by a qualified service 

person. More frequent cleaning may be required due to 

excessive lint from carpeting, bedding material, etc.  It 

is  imperative  the  control  compartments,  burners  and 

circulating  air  passageways  of  the  appliance  be  kept 

clean.
• Due to high temperatures, the appliance should be 

located out of high traffic areas and away from furniture 

and draperies.
Children and adults should be alerted to the 

hazards of high surface temperatures and should 

stay away to avoid burn or clothing ignition.

• Young children should be carefully supervised when in 

the same room as the appliance.  Toddlers, young children 

and others may be susceptible to accidental contact 

burns.  A physical barrier is required if there are at risk 

individuals in the house.  To restrict access to a fireplace 

or stove install an adjustable safety gate to keep toddlers, 

young  children  and  other  at  risk  individuals  out  of  the 

room  and  away  from  hot  surfaces.  Any  safety  screen, 

guard, or barrier removed for servicing an appliance must 

be replaced prior to operating the appliance.

•  Clothing  or  other  flammable  materials  should  not  be 

placed on or near the appliance.

• A barrier designed to reduce the risk of burns from the 

hot veiwing glass is provided with this appliance and shall 

be installed for the protection of children and other at-risk 

individuals. If the barrier becomes damaged, the barrier 

shall be replaced with the manufacturer’s barrier for this 

appliance
FOR YOUR SAFETY

• Installation and service must be performed by a qualified 

installer, service agency or gas supplier.
•  This  installation  must  conform  to  local  codes  or,  in  the 

absence  of  local  codes,  with  the  National  Fuel  Gas  Code, 

ANSI  Z223.1/NFPA  54,  or  the  Natural  Gas  and  Propane 

Installation Code, CSA B149.1.

• To prevent injury, do not allow anyone who is unfamiliar 

with the stove to operate it.

 

To prevent injury, if the pilot or pilot and burners 

have gone out on their own, open the glass door and 

wait  5  minutes  to  air  out  before  attempting  to  re-

light the stove.

•  Always  keep  the  area  around  these  appliances  clear  of 

combustible material, gasoline and other flammable liquids 

and vapours.
• These appliances should not be used as a drying rack for 

clothing or for hanging Christmas stockings/decorations.
• Due to the paint curing on the stove, a faint odor and slight

 

smoking will likely be noticed when the stove is first used.  

Open a window until the smoking stops.
Always connect this gas stove to a vent system and vent to 

the outside of the building envelope. Never vent to another 

room  or  inside  the  building.  Make  sure  the  specified  vent 

pipe  is  used,  properly  sized  and  of  adequate  height  to 

provide sufficient draft.  Inspect the venting system annually 

for blockage and signs of deterioration.

WARNING:  Failure to position the parts in accordance 

with  the  diagrams  in  this  booklet,  or  failure  to  use  only 

parts specifically approved with this appliance, may result in 

property damage or personal injury.

WARNING: 

Do not operate with the glass front removed, 

cracked or broken.  Replacement of the glass should be done 

by a licensed or qualified service person.
• Never use solid fuels such as wood, paper, cardboard, coal, 

or any flammable liquids, etc., in this appliance.
• Do not use this appliance if any part has been under water. 

Immediately call a qualified service technician to inspect the 

appliance and to replace any part of the control  system or 

any gas control which has been under water.
• Do not abuse the glass by striking it or slamming the door 

shut.
• 

If the S50I unit is pulled out of its installation, and the vent-

air intake system is disconnected for any reason, ensure that 

the vent-air intake pipes are reconnected and re-sealed in 

accordance to the instructions noted in
