4.2 Installation room
The boiler must be installed in rooms that comply with all local, state and
federal codes and laws. Before commissioning the boiler verify exhaust
ue and terminations are properly sealed and secured.
• Adequate combustion air and ventilation is required for safe and
proper installation of the boiler, regardless whether the combustion air
is taken from the outside (Direct Vent, sealed combustion) or inside
(room air for combustion).

WARNING: Insufcient ventilation of the boiler room can
lead to high air temperatures and lead to risk of personal
injury or death from ue gas poisoning!
• Make sure that intake and exhaust openings are sufciently sized and no
reduction or closure of openings takes place. If these are not provided, do
not operate the boiler (see section “4.7.2 Connecting ue gas systems”).
• The heating units cannot be installed outdoors. NEVER place this
appliance in a location that would subject it to temperatures at or near
freezing or temperature that exceed 120°F (49°C) while in operation.
Failure to properly locate this unit can result in premature failure.
• This appliance must be installed in a location so that any water
leaking from the unit or piping connections or relief valve openings
will not cause damage to the area surrounding the unit or any lower
oors in the structure. When such locations cannot be avoided, it
is recommended that a suitable drain pan, adequately drained, be
installed under the boiler. The pan must not restrict combustion air ow.
• When installed in a room with thin ooring, resonating noises may
occur. Isolate the boiler from direct contact with the oor to minimize
noise transmission.
• Do not allow excessive dust to collect on the appliance.

WARNING: If the information in these instructions is not
followed exactly, a re or explosion may result causing
property damage, personal injury or death.
• Do not store or use gasoline or other ammable vapors and liquids in
the proximity of this or any other appliance.
• Installation and service must be performed by a qualied installer,
service agency or the gas supplier.
• Please consider the space needed for accessibility to safety and
control devices and for performing maintenance operations.
