Initial Installation

WARNING: 
Operation of this heater when not connected to a properly installed and maintained venting system can 

result in carbon monoxide (CO) poisoning and possible death.

•  Remove the packaging from the appliance, and check to make sure there is no damage.  If damage is 

found, please report it to both the carrier and your dealer as soon as possible.

•  Before beginning, carefully check the glass door and the log set
•  Locate a position where the flue system of the stove can be properly installed without damaging the 

integrity of the building; e.g. cutting a wall or ceiling joist.

•  Check stove and flue system clearance requirements.
•  Locate the stove where it can be accessed by a gas supply line.
•  Locate the stove in a large and open room that is centrally located in the house.  This will optimize heat 

circulation and comfort.

•  As the stove can be equipped with a convection fan, ensure that an electrical outlet is within 6 ft (1.8 

m) of the stove.

•  The flow of combustion and ventilation air must not be obstructed.

When planning your installation, it will be necessary to select the proper length of vent pipe for your 

particular requirements. It is important to note when passing through a wall, the maximum allowable 

wall thickness is 10 inches (25.4 cm), 1½ inches (3.8 cm) clearance to combustibles must be maintained. 

Select  the  amount  of  vertical  rise  desired  for  “vertical-to-horizontal”  type  installations.  To  determine 

the length of vent pipe required for vertical installations, measure the distance from the appliance flue 

outlet to the ceiling, the ceiling thickness, the vertical rise through the attic or second story, and allow 

for sufficient vent height above the roof line. For two story applications, a fire stop is required at each 

floor level. If an offset is needed in the attic, additional pipe and elbows will be required. To connect the 

venting system to the appliance flue outlet, a twist-lock adapter is built into the appliance at the factory.
