contaminants; combustion air should be drawn from a CLEAN source
(e.g. outdoors) and the boiler should be isolated from interior dust
sources. Do not seal boiler case openings directly when ring - allow for
air circulation and ventilation in the immediate area.
SURFACE DISTANCE FROM COMBUSTIBLE SURFACES
Front 1"
Rear 0"
Left Side 1"
Right Side 1"
Top 12”
Bottom 12"
Table 2 - Clearance from boiler cabinet
A minimum distance below the boiler of 12" is required to provide
clearance for the supplied condensation trap assembly. More clearance will
typically be required to accommodate associated water and gas piping.
EXHAUST VENTING AND AIR INTAKE
It is important to carefully plan the installation to ensure the appropriate
vent materials, travel and termination decisions are incorporated. Specic
attention is warranted to manage the impact of the steam plume normally
experienced at the exhaust terminal of a condensing boiler. Generally,
intake and exhaust pipes should terminate at a rooftop or sterile wall
location, to maximize customer satisfaction. Keep exhaust plumes
well away from all building air intakes including those of neighbouring
properties.
WARNING
DO NOT MOUNT THIS
BOILER TO HOLLOW
WALL STRUCTURES - The
combined weight of the
boiler, its water contents
and associated piping
components can exceed 300
pounds. Fasteners must be
rated for this strain, and must
be rmly anchored into solid
material that will support this
weight.
Installers are to take all
necessary precautions
to avoid injury during the
installation of this boiler.
