When installing a heater for outdoor mounting, you must
always use the appropriate outdoor mounting kit which has
been specifically designed by L.B. White Co., Inc. for the
respective heater being installed. All outdoor mounting kits
are listed in Section 10, Kits and Accessories.
In addition to following the installation instructions provided
with the kit, attention must also be given to these areas:
■
The heater and its associated ducting must be
mounted so it will not interfere with electrical
raceways or waterlines.
■
The heater and ducting must sit level when installed
so the dampers open and close properly.
■
To prevent water entry into the case; remove the cage
nuts from the case top and install the hole plugs
(provided with the kit) into each hole. A sloped top
accessory kit is also available for heater models
AW230 and AW250 to facilitate water runoff (Kit Part
#500-20257.)
■
The heater should be installed at least 18 inches
above the ground or to height that would prevent snow
blockage at the heater’s air inlets.
■
Clearances from nearest combustible materials must
always be maintained. (See heater dataplate or
specification section within this guide.)
■
When mounted outside, the heater will be pulling in
fresh outdoor air for combustion. Therefore, during
periods of cold temperatures, the outlet air
temperature of the heater will also drop. Unless
building ventilation is properly managed, increased
fuel gas use may occur on outdoor mounted heaters.
