Sunstar Patio Heaters SGL Glass Serries 2 Stage

The required clearance to combustibles for an SGL50 heater is dependent on the mounting angle:It's important to note that the stated clearance represents a surface temperature of 117ºF (65ºC) above room temperature.
- 0º Mounting Angle: 22 inches above and 60 inches below.
- 30º Mounting Angle: 22 inches above and 60 inches below.
Building materials with low heat tolerance, such as plastics, vinyl siding, canvas, and tri-ply, may degrade at temperatures lower than this clearance indicates.
Therefore, the installer is responsible for ensuring that adjacent materials are protected from degradation.
While 18 inches (457 mm) is a general minimum clearance for gas or fuel-oil heat-producing appliances from combustible materials, and 36 inches (914 mm) for solid fuel-burning appliances, specific manufacturer's instructions or listings for the SGL50 should always be followed.
These clearances may be reduced with the use of appropriate protection like heat shields or double-wall piping.

Important Reminders:

Always prioritize the SGL50 manufacturer's specific installation instructions. SunStar Heating Products, Inc. provides SGL Glass series information.
Consult with local building and fire officials for permits, restrictions, and inspections in your area.
Consider the heat tolerance of surrounding materials and take appropriate measures to prevent degradation
