OUTDOOR INSTALLATION
VENTING GUIDELINES
INDOOR INSTALLATIONS
The heater must be placed in a suitable room on a non-combustible
floor or on a non-combustible base and in an area where leakage
from heat exchanger or water connections will not result in
damage to the area adjacent to the heater or the structure. When
such locations cannot be avoided, it is recommended that a
suitable drain pan with adequate drainage, be installed under the
heater. The pan must not restrict air flow.
Installations in basements, garages, or underground structures
where flammable liquids may be stored must have the heater
elevated 18 inches from the floor using a non-combustible base.
The following minimum clearances from combustible materials
must be provided.
