Operating Instructions and Owner’s Manual

APPLICATIONS

This is 

not

 an explosion proof heater. Consult your local fire marshal, 

insurance carrier, and other authorities for approval of the proposed 
installation.

COMMERCIAL/INDUSTRIAL

This patio heater is specifically designed to provide heated comfort for 
outdoor or patio installation. Not for use in residential dwellings.

CLEARANCES TO COMBUSTIBLES

A critical safety factor to consider before installation is the clearances 
to combustibles. Clearance to combustibles is defined as the minimum 
distance you must have between the infrared surface, or reflector, and 
the combustible item. Considerations must also be made for moving 
objects around the infrared heater. The following is a partial list of 
items to maintain clearances from:

Combustible items:

• Wood • Chemicals • Paper • Wall or roof insulation • Fabric • 
Plastics

Moving objects:

• Overhead doors • Hoists • Vehicle lifts • Car wash equipment • 
Cranes

Refer to 

Table 3

 for required minimum clearances to combustibles.

Hazards:

WARNING: For maximum safety the building must be 

evaluated for hazards before installing the heater system.

Examples include, but are not limited to:

• 

Gas and electrical lines • Combustible and explosive materials 
• Chemical storage areas • Areas of high chemical fume 
concentrations • Provisions for accessibility to the heater 
• Adequate clearances around air openings • Combustion 
and ventilating air supply • Vehicle parking areas • Vehicles 
with lifts or cranes • Storage areas with stacked materials • 
Lights • Sprinkler heads • Overhead doors and tracks • Dirty, 
contaminated environment

• 

Children and adults should be alerted to the hazards for high 
surface temperatures and should stay away to avoid burns or 
clothing ignition.

• 

Young children should be carefully supervised when they are in 
the same space as the heater.

• 

Clothing or other flammable materials should not be hung from 
the heater, or placed on or near the heater.

• 

Any guard or other protective device removed for servicing the 
heater must be replaced prior to operating the heater.

• 

Installation and repair should be done by a qualified service 
person. The heater should be inspected before use and at least 
annually by a qualified service person.

• 

More frequent cleaning may be required as necessary. It is 
imperative that the control compartment, air passageways, and 
burner of the heater are kept clean.

• 

When installing the infrared heater system, the minimum 
clearances to combustibles must be maintained. If you are unsure 
of the potential hazards, consult your local fire marshal, fire 
insurance carrier, or other qualified authorities on the installation 
of gas fired infrared heaters for approval of the proposed 
installation.

• 

If the heater is mounted beneath a non-combustible surface, an 
8 in. minimum top clearance must be maintained from the top of 
the heater to prevent overheating the controls.

NOTICE:

 Clearances to combustibles distances represent a surface 

temperature of 90°F (50°C) above ambient temperature.

• 

Ensure that building materials with a low heat tolerance (i.e., 
awnings, fabrics, plastics, sprinklers, insulation) are protected 
against degradation. This may require the heater to be 
mounted at a distance in excess of the published clearances 
to combustibles. Contact the factory or the building material 
manufacturer for additional information.

STANDARDS, CERTIFICATIONS, AND 
GOVERNMENT REGULATIONS

The installation of this heater must comply with all applicable local, 
state, and national specifications, regulations, and building codes 
(contact the local building inspector and/or fire marshal for guidance) 
before installing the heater system.

In the absence of local codes, the installation must conform to the 
latest edition of the National Fuel Code ANSI Z223.1 (NFPA 54).

Refer to the following standards and codes for application specific 
guidelines:

Public Garages:

The installation of this heater in public garages must conform with the 
Standard for Parking Structures, ANSI/NFPA 88A (latest edition), and 
must be at least 8 ft. above the floor.

Aircraft Hangars:

The installation of this heater in aircraft hangars must conform with 
the Standard for Aircraft Hangars, ANSI/NFPA 409 (latest edition). The 
heater must be installed at least 10 ft. above the upper wing surfaces 
and engine enclosures of the highest aircraft which might be stored 
in the hangar. In areas adjoining the aircraft storage area, the heaters 
must be installed at least 8 ft. above the floor. The heaters must be 
located in areas where they will not be subject to damage by aircraft, 
cranes, moveable scaffolding or other objects.

High Altitude:

The installation of this heater is approved, without modifications, for 
elevations up to 2,000 ft. above MSL (sea level). Contact Heatstar, Inc. 
for installations above these elevations.

Gas Connection:

WARNING: An approved connector, suitable for the 

environment of equipment usage, is required. Visible 
or excessive swaying, flexing, and vibration of the gas 
connections must be avoided to prevent failure.

Neither the gas pipe nor the connector shall be placed in the 
flue discharge area or in direct contact with infrared rays. In 
no case shall the gas supply support or bear weight of the 
heater.

To ensure your safety, and to comply with the terms of the warranty, 
all units must be installed in accordance with these instructions. Under 
no circumstance should the gas supply line provide support to the 
heater.

The gas supply to the infrared patio heater must be connected and 
tested in accordance with national, state, provincial, and local codes 
along with the guidelines in the manual. In the United States, refer 
to the latest edition of the ANSI Z223.1 (NFPA 54) Standard and in 
Canada, refer to the latest edition of the CAN/ CGA B149.1 Standard.
