D. RESIDENTIAL GARAGE INSTALLATION
PRECAUTIONS
If the heater is located in a residential garage, per ANSI Z223.1:

Mount the bottom of the heater a minimum of 18” above the floor of the garage, to ensure the burner and ignition devices are
well off the floor.

Locate or protect the heater so it cannot be damaged by a moving vehicle.
E. EXHAUST VENT AND INTAKE PIPE
Vents must be properly supported. The heater exhaust and intake connections are not designed to carry heavy weight. Vent support
brackets must be within 1’ of the heater and the balance at 4’ intervals. Venting must be readily accessible for visual inspection for the
first 3’ from the heater.
The heater is rated ANSI Z21.13 Category IV (pressurized vent, likely to form condensate in the vent), and requires a special vent
system designed for pressurized venting.
