A. Positioning
Maintain clearance around and above unit to provide mini-
mum distance from combustible materials, proper airflow,
and service access. See Fig. 1A and 1B Notes.
Do not install unit in an indoor location. Do not locate unit
air inlets near exhaust vents or other sources of contami-
nated air.
Be sure that unit is installed so that snow will not block the
combustion intake or flue outlet.
Unit may be installed directly on wood flooring or on Class
A, B, or C roof-covering material when roof curb is used.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
Position unit on roof curb so that the following clearances are
maintained:
1
/
4
-in. clearance between roof curb and base
rails on each side and duct end of unit; 3
5
/
16
-in. clearance
between roof curb and condenser section end. (See Fig. 3,
section C-C.)
Locate mechanical draft system flue assembly at least 48 in.
from an adjacent building or combustible material. When
unit is located adjacent to public walkways, flue assembly
must be at least 7 ft above grade.
Flue vent discharge must have a minimum horizontal clear-
ance of 48 in. from electric and gas meters, gas regulators,
and gas relief equipment.
Flue gas can deteriorate building materials. Orient unit so
that flue gas will not affect building materials.
Adequate combustion-air space must be provided for proper
operation of this equipment. Be sure that installation com-
plies with all local codes and Section 5.3, Air for Combustion
and Ventilation, NFGC (National Fuel Gas Code), ANSI
(American National Standards Institute) Z223.1-latest year
and addendum Z223.1A-latest year. In Canada, installation
must be in accordance with the CAN1. B149.1 and
CAN1.B149.2 installation codes for gas burning appliances.
