o
F / 37
o
C or greater, such
as boiler flue pipes, space heaters, etc.) may damage plastic

NOTE:
If you do not provide the minimum clearances shown in Figure
1 it might not be possible to service the appliance without removing
it from the space.
The space must be provided with combustion / ventilation
air openings correctly sized for all other appliances located in
the same space as the appliance. The appliance cover must be
securely fastened to prevent the appliance from drawing air from
the appliance room. This is particularly important if the appliance
is in a room with other appliances. Failure to comply with the
above warnings could result in substantial property damage,
severe personal injury, or death.
NOTE:
A combustible door or removable panel is acceptable front
clearance.
D. Residential Garage and Closet Installations
Precautions
If the heater is located in a residential garage, per ANSI Z223.1:
• Install the appliance burner and ignition devices a minimum
of 18” above the floor of the garage. This will ensure the
burner and ignition devices are well off the floor.
• When raising the appliance ensure the entire bottom and
fully filled weight of the appliance are fully supported.
• Locate or protect the appliance so it cannot be damaged by
a moving vehicle.
Check with your local Authority Having Jurisdiction for
requirements when installing the appliance 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.
E. Exhaust Vent and Intake Pipe
The appliance is rated ANSI Z21.10.3 Category IV (pressurized vent,
likely to form condensate in the vent) and requires a special vent
system designed for pressurized venting.
NOTE: The venting options described here (and further detailed
in the Venting section, this manual) are the lone venting options
approved for this appliance. Failure to vent the appliance in
accordance with the provided venting instructions will void the
warranty.
The exhaust discharged by this appliance may be very hot. Avoid
touching or other direct contact with the exhaust gases of the vent
termination assembly. Doing so could result in severe personal
injury or death.
Do not attempt to vent this appliance by any means other than
those described in this manual. Doing so will void the warranty
and may result in severe personal injury or death.
Failure to vent the appliance properly will result in serious personal
injury or death.
The space must be provided with correctly sized combustion/
ventilation air openings for all other appliances located in the
space with the appliance. 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 appliance in an attic. Failure to comply with these warnings
could result in substantial property damage, severe personal
injury, or death.
