2.3.3 Flooring - Typical Installation
Do not install the heater directly on carpeting
without placing a non-combustible platform between
the carpeting and the heater. If the heater is installed in
a carpeted alcove, the entire floor of the alcove must
be covered by a non-combustible panel. The panel
must be strong enough to carry the total weight of the
heater and all piping, pumps, and any other equipment
attached to the heater. For rooftop installation, see
Figure 11 through Figure 13.
2.4 Combustion and Ventilation
Air Supply
All indoor installations must have openings to
outside air for combustion, ventilation and dilution of
flue gases from inside the building (see Figure 14 and
Table 2 ). Bradford White does not recommend indoor
installations that do not provide combustion air from
outside the building.
