Safety Warnings & Recommendations

ELECTRICAL: The use of a surge protected power bar is recommended. 

The unit must be grounded. 

The grounded electrical cord should be connected to a standard 110-120 volts (4.2 Amps), 60 hertz electrical 

outlet and also must be accessible. If this power cord should become damaged, a replacement power cord 

must be purchased from the manufacturer or a qualified Enviro dealer. Be careful that the electrical cord is 

not trapped under the appliance and that it is clear of any hot surfaces or sharp edges. This unit’s maximum 

power requirement is 504 watts.
When installing the stove in a mobile home, it must be electrically grounded to the steel chassis of the home 

and bolted to the floor.  

GLASS:

 Do not abuse the glass by striking or slamming the door.  Do not attempt to operate the stove with 

broken glass. The stove uses ceramic glass. Replacement glass must be purchased from an Enviro dealer.  

Do not attempt to open the door and clean the glass while the unit is in operation or if glass is hot. To clean 

the glass, use a soft cotton cloth and mild window cleaner, gas or wood stove glass cleaner, or take a damp 

paper towel and dip into the fly ash. This is a very mild abrasive and will not damage the glass.

KEEP ASH PAN FREE OF RAW FUEL. 

DO NOT PLACE UNBURNED OR NEW PELLET FUEL IN ASH PAN. 

A fire in the ash pan may occur.

INSTALLATION:

  Contact your local building or fire official to obtain a permit and any information on 

installation restrictions and inspection requirements for your area. 
Be sure to maintain the structural integrity of your home when passing a vent through walls, ceilings, or 

roofs, and all construction meets local building codes. It is recommended that the unit be secured into its 

position in order to avoid any displacement. This appliance must be installed on a floor with an adequate 

load  bearing  capacity,  if  existing  construction  doesn’t  meet  load  capacity,  suitable  measures  (e.g.  load 

distributing plate) must be taken to achieve it.
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT.

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

FRESH AIR:

 This unit uses large quantities of air for combustion; outside Fresh Air connection is 

strongly 

recommended. Fresh Air 

must

 be connected to all units installed in Mobile and “Air Tight Homes” (R2000) 

or where required by local codes. 
Consider all large air moving devices when installing your unit and provide room air accordingly. NOTE: 

Extractor fans when operating in the same room or space as the appliance may cause problems. Limited air 

for combustion may result in poor performance, smoking and other side effects of poor combustion. 
The  stove’s  exhaust  system  works  with  negative  combustion  chamber  pressure  and  a  slightly  positive 

chimney pressure. It is very important to ensure that the exhaust system be sealed and airtight. The ash 

pan and viewing door must be locked securely for proper and safe operation of the pellet stove.
Do not burn with insufficient combustion air. A periodic check is recommended to ensure proper combustion 

air is admitted to the combustion chamber.  Setting the proper combustion air is achieved by adjusting the 

slider damper located on the left side of the stove.
Soot or creosote may accumulate when the stove is operated under incorrect conditions such as an rich 

burn (black tipped, lazy orange flames).
If you have any questions with regards to your stove or the above-mentioned information, please feel free 

to contact your local dealer for further clarification and comments.

SINCE SHERWOOD INDUSTRIES LTD. HAS NO CONTROL OVER THE INSTALLATION OF YOUR 

STOVE, SHERWOOD INDUSTRIES LTD. GRANTS NO WARRANTY IMPLIED OR STATED FOR THE 

INSTALLATION  OR  MAINTENANCE  OF  YOUR  STOVE.  THEREFORE,  SHERWOOD  INDUSTRIES 

LTD. ASSUMES NO RESPONSIBILITY FOR ANY CONSEQUENTIAL DAMAGE(S).
