D. RESIDENTIAL GARAGE INSTALLATION
If the boiler is located in a residential garage, per ANSI Z223.1:
Mount the bottom of the boiler 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 boiler so it cannot be damaged by a moving vehicle.
E. EXHAUST VENT AND INTAKE PIPE
Vents must be properly supported. The boiler exhaust and intake connections are not designed to carry heavy weight. Vent support
brackets must be within 1’ of the boiler and the balance at 4’ intervals. Venting must be readily accessible for visual inspection for the
first 3’ from the boiler.
The boiler 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.
You must also install air intake piping from outdoors to the boiler flue adaptor. The resultant installation is categorized as direct vent
(sealed combustion).
NOTE: To prevent combustion air contamination, see Table 3 in this section when considering exhaust vent and intake pipe
termination.
Exhaust vent and intake pipe may be vented vertically through the roof or out a side wall. Venting methods are detailed in the Venting
Section. Do not attempt installation using any other means. Be sure to locate the boiler so exhaust vent and intake piping can be routed
through the building and properly terminated. Exhaust vent and intake piping lengths, routing, and termination method must comply with
methods and limits given in the venting section.
F. PREVENT COMBUSTION AIR CONTAMINATION
Install intake piping for the boiler as described in the Venting section. Do not terminate exhaust in locations that can allow
contamination of intake air.
Ensure that the intake air will not contain any of the contaminants below. For example, do not pipe intake near a swimming pool. Avoid
areas subject to exhaust fumes from laundry facilities. These areas always contain contaminants. Contaminated air will damage the
boiler, resulting in possible substantial property damage, severe personal injury, or death.
