Table B. Minimum Clearances from Combustible Surfaces
For ease of servicing, we recommend a clearance of at
least 24" (610 mm) for both the left and right side, and
also the top. This will enable the heater to be serviced in
its installed location, that is, without needing to move the
header.
Clearances less than these may require removal of the
heater to service either the heat exchanger or the burner.
In either case, the heater must be installed in a manner
that will enable the heater to be serviced without removing
any structure around the heater.

Flooring
This heater can be installed on combustible flooring.

Outdoor Heater Installation

These heaters are design-certified for outdoor installation,
when equipped with the approved vent cover designated
for outdoor use.
A WARNING: The heater shall not be located in an
area where water sprinklers, or other devices, may cause
water to spray through the cabinet louvers and into the
heater. This could cause internal rusting or damage
electrical components, and void the warranty.
A WARNING: Do not install within 3' (0.9 m) of a heat
pump or an outdoor condensing unit. Strong air intake
from this type of equipment can disturb the combustion
process and cause damage or personal injury.
