Air for Combustion.
The unit heater shall be installed in
a location in which the facilities for ventilation permit
satisfactory combustion of gas, proper venting, and the
maintenance of ambient temperature at safe limits under
normal conditions of use. The unit heater shall be located
in such a manner as not to interfere with proper circulation
of air within the confined space. When buildings are so
tight that normal infiltration does not meet air
requirements, outside air shall be introduced per Sections
1.3.4.2 and 1.3.4.3 of ANSI Z223.1 for combustion
requirements. A permanent opening or openings having a
total free area of not less than one square inch per
5,000 Btu/h (1.5 Kw) of total input rating of all appliances
within the space shall be provided.

Clearances
Each gas unit heater shall be located with respect to
building construction and other equipment so as to permit
access to the Unit Heater.
building construction and other equipment so as to permit
access to the Unit Heater.
Unit sizes 30–120: Clearance between vertical walls and
the vertical sides of the unit heater shall be no less than
1 inch (25.4 mm). However, to ensure access to the control
box and fan, a minimum of 18 inches (457 mm) is required
for the fan, and control box side. A minimum clearance of
1 inch (25.4 mm) must be maintained between the top of
the vertical sides of the unit heater shall be no less than
1 inch (25.4 mm). However, to ensure access to the control
box and fan, a minimum of 18 inches (457 mm) is required
for the fan, and control box side. A minimum clearance of
1 inch (25.4 mm) must be maintained between the top of
the Unit Heater and the ceiling. The bottom of the Unit
Heater must be no less than 1 inch (25.4 mm) from any
combustible. The distance between the flue collector and
any combustible must be no less than 1 inch (25.4 mm).

Unit sizes 150–400: Clearance between vertical walls and
the vertical sides of the unit heater shall be no less than
6 inches (152 mm). However, to ensure access to the
control box, a minimum of 18 inches (457 mm) is required
for the control box side. A minimum clearance of 6 inches
(152 mm) must be maintained between the top of the unit
heater and the ceiling. The bottom of the unit heater must
be no less than 12 inches (305 mm) from any combustible.
The distance between rear of unit and vertical wall should
be no less than 18 inches to maintain inlet air flow. The
distance between the flue collector and any combustible
must be no less than 6 inches (152 mm).

WARNING
Overheating or Flooding Could Cause Fire
or Explosion!
or Explosion!
Overheating or flooding (where any part of the unit
heater has been under water) could result in fire or
explosion. Should overheating occur, or the gas supply
fails to shut off, shut off the manual gas valve to the
unit heater before shutting off the electrical supply. Do
not use the unit heater if any part has been under
water. Immediately call a qualified service technician to
inspect the unit heater and replace any gas control
which has been underwater. Failure to follow these
recommendations could result in death or serious
injury.

WARNING
Hazardous Gases and Flammable Vapors!
Exposure to hazardous gases from fuel substances
have been shown to cause cancer, birth defects or other
reproductive harm. Improper installation, adjustment,
alteration, service or use of this product could cause
flammable mixtures. To avoid hazardous gases and
flammable vapors follow proper installation and set up
of this product and all warnings as provided in this
manual. Failure to follow all instructions could result in
death or serious injury.

WARNING
Heavy Objects!
Make certain that the lifting methods used to lift the
heater and the method of suspension used in the field
installation of the heater are capable of uniformly
supporting the weight of the heater at all times. Make
certain that the structure to which the heater is
mounted is capable of supporting its weight. Under no
circumstances must the gas lines, the venting system
or the electrical conduit be used to support the heater;
or should any other objects (i.e. ladder, person) lean
against the heater, gas lines, venting system or the
electrical conduit for support. Failure to follow
recommendations could result in death or serious
injury.
