Regardless of the venting arrangement that will be 
connected to the heater, the following general guide-
lines for venting must be followed:

1. The 3" (80 mm) flue pipe must be centered inside 

the 5" (125 mm) air supply pipe.

2. The total length of vent pipe (horizontal and verti-

cal runs combined, plus the length of the exterior 
termination) must not exceed 10' (3048 mm), and 
must not be less than 2' 6" (762 mm). A maximum 
of two elbows are allowed with natural gas, one 
elbow with propane.

3. The vent terminal, mounted outside of the building, 

should not be located above walkways. Conden-
sate produced during operation of the heater 
could drip onto the walkway forming ice during 
cold weather.

4. Be sure that the venting installation is in accor-

dance with all applicable local codes and recom-
mendations of the local gas company.

5. DO NOT connect this heater to a separate chim-

ney and DO NOT common vent with any other fuel 
burning appliance.

IMPORTANT: For standard flue, seal all vent pipe 

connections with high temperature silicone seal-
ant. Where required, drill holes and secure each 
connection with three sheetmetal screws.

NOTE: Failure to seal all flue connections 3" (80 

mm) will result in erratic heater operation.
