E. RESIDENTIAL GARAGE AND CLOSET INSTALLATIONS
Check with your local Authority Having Jurisdiction for requirements when installing boiler in a garage or closet. Please read the entire
manual before attempting installation. Failure to properly take factors such as venting, piping, condensate removal, and wiring into
account before installation could result in wasted time, money, and possible property damage and personal injury.
PRECAUTIONS
If the boiler is located in a residential garage, it should be installed per the latest edition of the National Fuel Gas Code, ANSI Z223.1,
and CGA-B149 Installation Code in Canada.
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.
The space must be provided with correctly sized combustion/ventilation air openings for all other appliances located in the space with
the boiler. For power venting installations using room air for combustion, refer to the venting section, this manual, for descriptions of
confined and unconfined spaces. Do not install the boiler in an attic. Failure to comply with these warnings could result in substantial
property damage, severe personal injury, or death.
F. EXHAUST VENT AND INTAKE PIPE
Vents must be properly supported. The appliance exhaust and intake connections are not designed to carry heavy weight. Vent support
brackets must be within 1’ of the appliance and the balance at 4’ intervals. Venting must be readily accessible for visual inspection for
the first 3
’ from the appliance.
NOTE:
To prevent combustion air contamination, see Table 9 in this section when considering exhaust vent and intake pipe
termination.
The appliance 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.
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 appliance 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.
G. PREVENT COMBUSTION AIR CONTAMINATION
Install intake piping for the appliance 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
appliance, resulting in possible substantial property damage, severe personal injury, or death.
