Air Circulation Of The Heating System - J. A. Roby ULTF Instruction Manual

AIR CIRCULATION OF THE HEATING SYSTEM

Always refer to the applicable building code before installing the hot air conduct.
Hot air pipe:
An air supply must be installed if:
• The appliance seems to have an irregular draft control, a smoke return, a bad
combustion and a counterblow whether you have combustion or not.
• Your other appliances, such as hearths or other heating appliances, release
odors, provide poor performance, provoke smoke return or a counterblow
whether there is combustion or not.
• If the window is open, even slightly, in the calm weather (no wind), the situation
above is solved.
• Your home is built with vapour barrier and airtight windows, and/or with a system
device to blow the air outside.
In these circumstances, which mean the air infiltration is inefficient, you must ensure an
adequate air supply.
* In doubt, it is recommended to ensure an adequate supply of fresh air.
