INDOOR INSTALLATION AND VENTING

POSITIVE AND NEGATIVE PRESSURE VENTING SySTEMS
The heater is designed such that it may be vented using either a negative-pressure or a positive-pressure
venting system. The appropriate system of venting for a particular site will depend on many factors such as
vent termination needs (horizontal/vertical), and the cost of venting system. Table 3 lists the indoor venting
kits available and the limitations of each system.

CLEARANCES

The heater must be installed such that the installation and
service clearances from combustible materials shown in Table
4 are maintained. This heater may be installed on combustible
floors. Do not install heater in a closet.

AIR SUPPLy

Indoor installations and outdoor shelters (confined spaces)
must be provided with adequate combustion and ventilation air
vents to assure proper heater operation. These vents must be
sized according to the requirements stated in paragraph A or B below (whichever applies to the installation).
These vents must never be obstructed when heater is in operation.
When air blowers are used in spa/hot tub installations and are located in proximity to the heater, caution
must be observed to ensure sufficient combustion air is available to the heater for proper combustion. A separate
blower air duct is recommended.
