Locate mechanical draft system flue assembly at least
48 in. from any opening through which combustion prod-
ucts could enter the building, and at least 48 in. from an ad-
jacent 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 Combus-
tion 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.
