OUTSIDE FRESH-AIR CONNECTION:

This Heater must have adequate air for proper combustion in the room that it is installed.

A Fresh-air intake is strongly recommended for all installations. Failure to install intake air may result in improper combustion as well as the unit smoking during power failures.

The inlet to the intake must be below and a minimum of 305mm (12”) away from the unit exhaust outlet.

Outside fresh air is mandatory when installing this unit in airtight homes.

When connecting to an outside fresh air source, do not use plastic or combustible pipe. A 50mm minimum (2”) ID (inside diameter) steel, aluminum or copper pipe should be used. It is recommended, when you are installing a fresh air system, to keep the number of bends in the pipe to a minimum.
