1) GENERAL INFORMATION
This heater complies with ANZI Z83.20 (current
standard) and CSA 2-34.
This heater is a self-contained infrared radiant tube
heater for use in locations where flammable gases
or vapors are not generally present (as defined by
OSHA acceptable limits) and is intended for space
heating of garages, vestibules and entry ways,
workshops, enclosed patios, golf practice ranges
and most industrial and commercial applications.
DO NOT install this heater in residential bedrooms
or bathrooms, mobile homes or recreational vehicles.
For indoor installation only. Not for use in
residential dwellings.
INSTALLATION REQUIREMENTS
The installation must conform to local building codes
or in the absence of local codes, with the National Fuel
Gas Code ANSI Z223.1/NFPA54 or the Natural Gas
and Propane Installation Code CSA B149.1. Heaters
shall be installed by a licensed contractor or licensed
installer. Clearances to combustibles as outlined in this
manual should always be observed. In areas used for
storage of combustible materials where they may be
stacked below the heater, NFPA54 requires that the
installer must post signs that will “specify the maximum
permissible stacking height to maintain the required
clearances from the heater to combustibles.”
Every heater shall be located with respect to building
construction and other equipment so as to permit
access to the heater. Each installer shall use quality
installation practices when locating the heater and
must give consideration to clearances to combustible
materials, vehicles parked below, lights, overhead
doors, storage areas with stacked materials, sprinkler
heads, gas and electrical lines and any other possible
obstructions or hazards. Consideration also must be
given to service accessibility.
The heater, when installed in aircraft hangars and
public garages, must be installed in accordance with
ANSI/NFPA 409-latest edition (Standard for Aircraft
Hangars), ANSI/NFPA 88a-latest edition (Standard for
Parking Structures), and ANSI/NFPA 88b-latest edition
(Standard for Repair Garages) with the following
clearances:
At least 10 feet above the upper surfaces of wings or
engine enclosures of the highest aircraft that may be
housed in the hangar and at least 8 feet above the
floor in shops, offices, and other sections of hangars
communicating with aircraft storage or service areas.
At least 8 feet above the floor in public garages.
Minimum clearances marked on the
heater must be maintained from vehicles parked
below the heater.
FOR CANADA ONLY
a. Installation of this appliance is to be in accordance
with latest edition of CSA B149.1 (Natural Gas and
Propane Installation Code).
b. For installation in public garages or aircraft
hangars, the minimum clearances from the bottom
of the infrared heater to the upper surface of the
highest aircraft or vehicle shall be 50 percent
greater than the certified minimum clearance, but
the clearance shall not be less than 8 feet.
Although these heaters may be used in many
applications other than space heating (e.g., process
heating), Sterling will not recognize the warranty for
any use other than space heating.
This heater is for Indoor Installation and Covered Patio
Installation only and can be used in either Vented or
Unvented mode. The term Unvented actually means
Indirect Vented. While the products of combustion
are expelled into the building, national codes require
ventilation in the building to dilute these products of
combustion. This ventilation may be provided by
gravity or mechanical means.
This heater is not an explosion proof heater.
Where the possibility of exposure to volatile and low
flash point materials exists, it could result in property
damage or death. This heater must not be installed in
a spray booth where the heater can operate during the
spraying process. Consult your local fire marshal or
insurance company.
High Altitude:
Appliances are supplied as standard for altitudes of
0 to 2,000 feet (0-610 m). High-altitude ratings are
obtained by a change in the orifice size. When ordered
for high altitude installations, burners are supplied by
the factory ready for high altitude installation. Check
the nameplate for altitude before proceeding with the
installation. In Canada the adjustment for altitude is
made in accordance with Standard CGA 2.17, Gas-
Fired Appliances for Use at High Altitudes.
