The Heatmax’s cold air return option can be connected to a new or to an existing cold air
return ductwork. In both cases, the minimum clearance to combustible material is 0”

7.4 Floor protector
Your furnace is designed to prevent the floor from overheating. However, it should be
placed on a non-combustible surface to protect the floor of the hot embers that might fall
from the furnace during loading and maintenance. There are differences between the floor
protection for Canada and the U.S., as shown in the Table and Figure below.
