CGTH INSTALLATION, OPERATION AND SERVICE MANUAL

4.5 General Venting Guidelines

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.
