The illustrations shown provide useful information on the installation of a chimney system. Each installation
is specific to the application and the job site. If you encounter a situation not covered by this illustration,
refer to the guide or consult the factory. The chimney systems illustrated in this manual have been tested
to and comply with UL 103 Type HT, Factory-Built Chimneys for Building Heating Appliances. Chimney
needs to be installed additionally in accordance with NFPA 211.
There is no limit on the angle or slope of an offset for gas or liquid fuel burning appliances, but with a solid
fuel burning appliance the slope must not be greater than 30 degrees (USA) or 45 degrees (Canada) from
vertical.
Chimney for combination fuel heating appliances which are capable of burning solid fuel or are convertible
to solid fuel are limited to the same 30 degrees (US) or 45 degrees (Canada) slope even if the current
choice of fuel is gas or oil.
