A.3 MOUNTING CLEARANCES
The heater should be positioned so that clearances from
combustible materials will meet or exceed those shown
in the following table. Also, ensure that there is at least
6” clearance on all sides of the burner for service access
and for free flow of combustion air. When the heater is
angle mounted, the burner/control assembly must remain
horizontal.
Ensure that there is adequate provision in the building
for combustion and ventilation supply. Installation must
meet minimum requirements and applicable codes.
