Vent Requirements 
•  The gas appliance and vent system must be vented directly to the outside of the building, and never be 
attached to a chimney serving a separate solid fuel or gas-burning appliance.  Each direct vent gas appliance 
must use its own separate vent system.   
•  In addition to the requirements listed here, follow the requirements provided with the vent. 
•  A firestop is required whenever the vent penetrates a wall, floor, or ceiling (passes through framing 
members).  Horizontal vent less than 48" (1219mm) above the fireplace must use the Travis Firestop (sku 
93006094 - it incorporates a 3" (76mm) clearance above, 1" (25mm) clearance below and to the sides of the 
vent).  Other penetrations only require a 1" (25mm) clearance and may use a standard firestop (make sure 
the required 1" (25mm) clearance is met). 
Vent Clearances  
•  The vent must maintain the required clearance to combustible materials to prevent a fire.  Do not fill air 
spaces with insulation.

Altitude Considerations  
• 
This heater has been tested at altitudes ranging from sea level to 6,000 feet (1800 M). In this testing we have found that 
the heater, with its standard orifice, burns correctly with just an air shutter adjustment. 
• 
Failure to adjust the air shutter properly may lead to improper combustion which can create a safety hazard. Consult your 
dealer or installer if you suspect an improperly adjusted air shutter.
