The combustion air inlet caps for multiple unit installations
must maintain the minimum 3 foot radius clearance below
or horizontally from the closest flue outlet. Multiple flue
outlet caps may be installed side by side and multiple air
inlet caps may be installed side by side but the 3 foot radius
minimum clearance between air inlet and flue outlet must
be maintained. All clearance and installation requirements
in this section and the applicable portions of the General
Vent in g section must be maintained on multiple unit
installations.
 CAUTION
Pool heaters which are shut down or will
not operate may experience freezing due
to convective air flow in the air inlet pipe
connected to the unit. If operated in
cold climates, continuous pump
operation is recommended to help
prevent freezing of pool water on
DirectAire systems. Proper freeze
protection must be provided. A pool
heater that is not in use in the winter
season must be properly drained and
winterized. See the Winterizing section
of the EnergyRite Service Manual.
