2.3.1 Installation Information
WARNING
Improper installation or maintenance can cause
nausea or asphyxiation from carbon monoxide in
flue gases which could result in property damage,
severe injury, or death.
MISE EN GARDE
Une mauvaise installation ou un entretien inadéquat
peut provoquer la nausée ou l’asphyxie en raison
de la présence de niveaux dangereux de monoxyde
de carbone dans les résidus de combustion et peut
entraîner des dommages matériels, des blessures
ou même la mort.
Avoid placing the boiler in locations where it can
cause damage by water or condensate leakage. If this is
not possible, provide a suitable drain pan under the
boiler to catch and divert any leakage. The pan must
not restrict air flow around the boiler.
Locate the boiler to provide adequate clearance
on all sides for inspection, service and to provide
adequate air circulation for proper operation.
Locate the boiler so the clearances from
combustible surfaces shown in Table 1 and Figure 17
are met.
Locate the boiler on a waterproof floor with a
floor drain and a 6 inch (15.2 cm) minimum curb on all
four sides to protect the building if boiler repairs are
needed.

WARNING
Do not force the damper to open or close by moving
the damper blade, turning the shaft, or turning the
position indicator. Doing so can cause an unsafe
condition, leading to property damage, injury or
death.
