Installation of Venting for Outdoor Units

Follow Guidelines
All of the following guidelines must be followed when installing the unit.
WARNING
Do not install units in locations where flue products can be drawn into adjacent building openings such as windows, fresh air
intakes, etc.
Distance from vent terminal to adjacent public walkways, adjacent buildings, operable windows and building openings shall conform with the local
codes. In the absence of local codes, installation shall conform with the National Fuel Gas Code, ANSI Z223.1 or the Canadian CAN/CGA B-149
Installation Codes.
The following guidelines must be followed for all outdoor units:
1. Building materials that will be affected by flue gases should be protected.
2. Maintain minimum horizontal clearance of 4 feet from electric meters, gas meters, regulators and relief equipment. In Canada, the mini-
mum clearance is 6 feet.
3. The combustion blower discharge on outdoor units must be located a minimum of 42 inches from any combustible materials.
4. Do not modify or obstruct the combustion air inlet cover or the combustion blower weatherhood.
5. Do not add vents other than those supplied by the manufacturer.
6. During the winter, keep the unit clear of snow to prevent any blockage of the combustion venting.
Install Stack (optional)
Clearance may require an exhaust stack. Install an exhaust stack as needed to the exhaust connection on the unit. Install a vent terminator
on the exhaust pipe.
Exhaust transition and vent termination must be purchased from the factory for proper operation. Exhaust pipe is by others.
Due to our policy of continuous product innovation, some specifications may change without notification.
